• #1 Nosebleeds (Epistaxis): Causes, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/13464-nosebleed-epistaxis

  Epistaxis is the medical term for a nosebleed. A nosebleed meaning a loss of blood from the tissue that lines the inside of your nose can occur in one or both nostrils. […] Your nose has many tiny blood vessels in it. These vessels help warm and moisten the air you breathe. But they lie close to the inner surface of your nose. When air moves through your nose, it can dry and irritate your blood vessels. This makes them very easy to injure or break, causing a nosebleed. […] The most common cause of nosebleeds is dry air. The air is typically drier in hot, low-humidity climates, areas at high altitudes, and heated indoor spaces. Dry air causes your nasal membrane (the delicate tissue inside your nose) to dry out and become crusty or cracked. It’s then more likely to bleed when rubbed or picked or when blowing your nose.

  https://www.health.harvard.edu/a_to_z/nosebleed-epistaxis-a-to-z

  The inside of the nose is covered with moist, delicate tissue (mucosa) that has a rich supply of blood vessels near the surface. When this tissue is injured, even from a minor nick or scratch, these blood vessels tend to bleed, sometimes heavily. […] Only rarely is a nosebleed life threatening or fatal. In these cases, the hemorrhage (severe bleeding) is usually from an artery in a posterior location, higher and deeper in the nose. […] In most cases of severe nosebleeds, the person has another health problem, such as high blood pressure or a bleeding disorder, or the person takes a blood-thinning medication that slows down the blood-clotting process. […] Certain people are more likely to get nosebleeds because of their environment, work history, health problems or use of medications that increase the tendency to bleed.

  Nosebleeds (Epistaxis) is a common condition in which there is bleeding from one or both sides of the nasal septum due to tearing of the small blood vessels that feed the septum caused by hard nasal picking, a severe impact on the nasal septum, dry nasal mucosa, or a condition in which the body’s temperature rises. […] Epistaxis or nosebleeds occurs when small blood vessels or capillaries in the nasal septum rupture or tear, leading to bleeding from one or both nostrils. […] Common conditions: Dry air due to high temperature and low relative humidity inside the living facility causes blood vessels in the nasal septum to dry out, clot, and burst when impacted. […] Certain medications, such as intranasal steroids for allergies, vasoconstrictor decongestants, and antihistamines, cause the nasal septum to dry out and bleed.

  Epistaxis, or nosebleed, is one of the most frequent ear, nose, and throat emergencies encountered in both primary care and emergency settings. […] Anterior nosebleeds typically arise from Kiesselbach’s plexus, located on the anterior nasal septum. […] The rupture of a blood vessel within the nasal mucosa causes nosebleeds. Rupture can be spontaneous, initiated by trauma, use of certain medications, and secondary to other comorbidities or malignancies. An increase in the patient’s blood pressure can increase the episode’s length. Anticoagulant medications, as well as clotting disorders, can also increase the bleeding time. […] Most nosebleeds occur in the anterior part of the nose (Kiesselbach plexus), and an etiologic vessel can usually be found on careful nasal examination. […] Bleeding from the posterior or superior nasal cavity is often termed a posterior nosebleed. This is usually presumed due to bleeding from the Woodruff plexus, the rear, and fine terminal branches of the sphenopalatine and posterior ethmoidal arteries. […] The differential diagnoses for epistaxis include the following: Nasal tumor, Disseminated intravascular coagulation, Hemophilia, Von Willebrand disease, Rhinitis, Foreign body in the nose, Drug toxicity (warfarin, NSAIDs).

  Epistaxis refers to bleeding from the nose. In the vast majority of cases they will terminate with simple manoeuvres and minimal intervention. However, in a small proportion of patients, epistaxis can lead to significant haemorrhage warranting urgent intervention. […] Anterior bleeds originate from ruptured blood vessels in Littles area, a highly-vascularised region formed by the anastomosis of 5 arteries, and cause around 90% of cases. Posterior bleeds originate from the posterior nasal cavity, typically from branches of the sphenopalatine arteries of the nose, and cause around 10% of cases (more common in older patients). […] Littles area (also known as Kiesselbachs plexus) is found on the anterior nasal septum and is an anastomosis of 5 arteries: anterior ethmoidal artery, posterior ethmoidal artery, sphenopalatine artery, greater palatine artery, and the septal branch of the superior labial artery.

  https://www.american-hospital.org/en/pathologie/epistaxis-nosebleeds

  Epistaxis, commonly known as a nosebleed, is loss of blood from the nasal cavities occurring when blood vessels in the nasal membrane rupture. This causes blood to flow from the nose, from one or both nostrils. […] In 80% of cases, the epistaxis originates in the Kiesselbach plexus, a vascular network located in the entrance of the nasal cavity. This area is particularly exposed to local inflammation, nasal membrane dryness and local trauma (often caused by picking). […] However, in 20% of cases, the epistaxis is posterior, caused when the blood vessels located at the back of the nose, near the throat, rupture. This can result in significant bleeding that flows into the throat. This type of epistaxis is more serious and difficult to control, and may require medical care. […] Several risk factors may contribute to nosebleeds, including high blood pressure, nasal dryness, nasal trauma, and excessive use of blood-thinning medications.

  A nosebleed is loss of blood from the tissue lining the nose. Bleeding most often occurs from one nostril only. […] Nosebleeds are very common. Most nosebleeds occur because of minor irritations of the inside of the nostrils or colds. […] The nose contains many small blood vessels that bleed easily. Air moving through the nose can dry and irritate the membranes lining the inside of the nose. Crusts can form that bleed when irritated. Nosebleeds occur more often in the winter, when cold viruses are common and indoor air tends to be drier. […] Most nosebleeds occur on the front of the nasal septum. This is the piece of the tissue that separates the two sides of the nose. This type of nosebleed can be easy for a trained professional to stop. Less commonly, nosebleeds may occur higher on the septum or deeper in the nose such as in the sinuses or the base of the skull. Such nosebleeds may be harder to control. However, nosebleeds are rarely life threatening.

  https://en.wikipedia.org/wiki/Nosebleed

  An increase in blood pressure (e.g. due to general hypertension) tends to increase the duration of spontaneous epistaxis. […] Anticoagulant medication and disorders of blood clotting can promote and prolong bleeding. […] Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nosebleeds as their blood vessels are less able to constrict and control the bleeding. […] The vast majority of nosebleeds occur in the front anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach’s plexus). This region is also known as Little’s area. Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff’s plexus, a venous plexus situated in the posterior part of inferior meatus.

  The second peak is in the over-65 age group, where the nose bleed may be more severe. […] In this group, nose bleeds may be indicative of a more serious health problem such as bleeding disorders and chronic sinus infections. […] Bleeding due to blood thinning medication, or sometimes as a side effect of nasal steroid sprays, are becoming more common. […] Bleeding from the back of the nose, while less common overall, is more likely to occur in older people. […] The risk of death from nose bleeds is extremely low. Out of 2.4 million deaths in the US in 1999, four were due to nose bleeds. […] If you have recurrent minor bleeds, try nasal decongestant sprays or nasal lubricants such as petroleum jelly (Vaseline). […] The other approach is to seal the bleeding vessels with chemical (such as silver nitrate applicators) or heat cauterisation.

  Most nosebleeds begin in the lower part of the septum, the semi-rigid wall that separates the two nostrils of the nose. […] More rarely, a nosebleed can begin high and deep within the nose and flow down the back of the mouth and throat even if the patient is sitting or standing. […] It is important to try to make the distinction since posterior (back of nasal cavity) nosebleeds are often more severe and almost always require a physician’s care. Posterior nosebleeds are more likely to occur in older people, persons with high blood pressure, and in cases of injury to the nose or face. […] Anterior nosebleeds are common in dry climates or during the winter months when heated, dry indoor air dehydrates the nasal membranes. Dryness may result in crusting, cracking, and bleeding. […] If the nosebleeds persist, you should see your doctor. Using an endoscope, a tube with a light for seeing inside the nose, your physician may find a problem within the nose that can be fixed. He or she may recommend cauterization (sealing) of the blood vessel that is causing the trouble.

  Posterior bleeds are often prolonged and difficult to control. They can be associated with bleeding from both nostrils and with a greater flow of blood into the mouth. […] Sometimes blood flowing from other sources of bleeding passes through the nasal cavity and exits the nostrils. It is thus blood coming from the nose but is not a true nosebleed, that is, not truly originating from the nasal cavity. Such bleeding is called „pseudoepistaxis”.

  Nose bleeds, or epistaxes, are often a mystery to the 60% of us who have had at least one in our lifetime. […] The nose is very prone to bleeding. This is because of the important role it plays in warming and humidifying the air we breathe. Large numbers of small blood vessels lie just under a thin layer of skin, as a heat exchange mechanism for air going to the lungs. […] A number of things can cause those vessels to rupture and the nose to bleed. […] Nasal infections and dryness are known to increase the frequency of bleeds. In one study, people who got nose bleeds were seven times more likely to have staphylococcal bacteria in their nose than than their peers who didnt get nose bleeds. […] Depending on the location of the ruptured blood vessels, the bleed is classified as anterior (the front part of the nose) or posterior (the back part of the nose). The blood from an anterior bleed will predominantly flow out of the nostrils, while with a posterior bleed, much of the blood will end up in the throat to be spat up or swallowed.

  “Blood thinning” or anticoagulant medicines such as aspirin, clopidogrel and warfarin do not cause nosebleeds themselves but, by reducing the blood’s ability to clot, can prolong bleeds, making them heavier and more clinically significant. […] The association between hypertension and epistaxis is probably a myth. Although it is common for patients to be hypertensive when they present with nosebleeds this has been attributed to stress, anxiety etc. […] If cautery fails to stop bleeding, or a bleeding point cannot be accessed with a cauterising device, in some areas a matrix sealant may be available. This is a mixture of collagen-derived particles and topical bovine-derived thrombin that can be used to control acute epistaxis. […] If cautery and matrix sealant (where available) have failed then nasal packing may be required. […] Cautery can also be used in the treatment of minor recurrent epistaxis which, although rarely serious, can be troublesome and affect quality of life.

  Common risk factors for nosebleeds include: A hot, dry indoor climate – This is a trigger for nosebleeds in parts of the United States where heat (especially forced hot air) is used during the winter. […] A deviated septum – If the wall between the two nostrils is shifted to one side (deviated), air flow in the nostrils is uneven. […] Colds and allergies – Upper respiratory tract infections and allergies cause inflammation in the nose, which can increase the risk of bleeding. […] Medical conditions – Examples include kidney failure, thrombocytopenia (low levels of the blood platelets needed for clotting), high blood pressure and hereditary bleeding disorders, such as hemophilia. […] Heavy alcohol use – Alcohol interferes with the normal activity of platelets in the blood, and this increases the time needed for blood clots to form.

  Epistaxis is the medical term for a nosebleed, which is a common presenting concern in the emergency room. The most common site of bleeding is the Kiesselbach plexus, where the vessels supplying the nasal mucosa anastomose, resulting in bleeding from the nostrils (anterior epistaxis). […] Posterior epistaxis may be a sign of life-threatening hemorrhages. […] Hereditary hemorrhagic telangiectasia, which is an autosomal dominant vasculopathy characterized by telangiectasia on the skin and mucosa, may cause recurrent epistaxis.

  Most of the time, nosebleeds are harmless, but when they run in the family, recur frequently, or are accompanied by tiny red spots on the skin, they may indicate a rare, genetic condition called hereditary hemorrhagic telangiectasia (HHT). […] That bad event which can be anything from a stroke to gastrointestinal bleeding to a brain abscess is due to a malformation of the blood vessels in people with HHT. […] People with HHT lack capillaries in certain key locations, causing blood to flow directly from the artery into the vein. This creates a fragile site called an arteriovenous malformation (AVM) that may bleed or lead to a host of other problems.

  Hypertension can be associated with older age and thus increased mucosal dryness, increased chance of traumatic blood vessel damage, and atherosclerotic disease, making it more prone to bleeding. […] Several studies and clinical observations suggest that while hypertension is not a direct cause of epistaxis, it is frequently associated with it and thus the anchor bias is very high with nose bleeds. […] Many patients presenting with epistaxis have been found to have elevated blood pressure at the time of the nosebleed. However, it is unclear whether the hypertension precedes the nosebleed or is a reactive response to the stress and anxiety caused by the bleeding event.

• #49 Nosebleeds (Epistaxis): Causes, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/13464-nosebleed-epistaxis

  Epistaxis is the medical term for a nosebleed. A nosebleed meaning a loss of blood from the tissue that lines the inside of your nose can occur in one or both nostrils. […] Your nose has many tiny blood vessels in it. These vessels help warm and moisten the air you breathe. But they lie close to the inner surface of your nose. When air moves through your nose, it can dry and irritate your blood vessels. This makes them very easy to injure or break, causing a nosebleed. […] The most common cause of nosebleeds is dry air. The air is typically drier in hot, low-humidity climates, areas at high altitudes, and heated indoor spaces. Dry air causes your nasal membrane (the delicate tissue inside your nose) to dry out and become crusty or cracked. It’s then more likely to bleed when rubbed or picked or when blowing your nose.

  An increase in blood pressure (e.g. due to general hypertension) tends to increase the duration of spontaneous epistaxis. […] Anticoagulant medication and disorders of blood clotting can promote and prolong bleeding. […] Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nosebleeds as their blood vessels are less able to constrict and control the bleeding. […] The vast majority of nosebleeds occur in the front anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach’s plexus). This region is also known as Little’s area. Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff’s plexus, a venous plexus situated in the posterior part of inferior meatus.

[…] Regardless of the cause, people who take aspirin or other medications that interfere with blood clotting (anticoagulants), who have a clotting disorder, or who have hardening of the arteries (arteriosclerosis) are more likely to develop nosebleeds. […] Posterior nosebleeds usually involve larger blood vessels than anterior nosebleeds. […] Anterior nosebleeds usually come from the front part of the nose (anterior nosebleed). The bleeding comes from small blood vessels in the cartilage that separates the two nostrils (called the nasal septum). […] High blood pressure (hypertension) is unlikely to cause a nosebleed, but in people with high blood pressure, the nosebleed may last longer than expected. […] For more severe or recurring bleeding, sometimes the doctor seals (cauterizes) the bleeding source with a chemical, silver nitrate, or an electrical current (electrocautery).

  “Blood thinning” or anticoagulant medicines such as aspirin, clopidogrel and warfarin do not cause nosebleeds themselves but, by reducing the blood’s ability to clot, can prolong bleeds, making them heavier and more clinically significant. […] The association between hypertension and epistaxis is probably a myth. Although it is common for patients to be hypertensive when they present with nosebleeds this has been attributed to stress, anxiety etc. […] If cautery fails to stop bleeding, or a bleeding point cannot be accessed with a cauterising device, in some areas a matrix sealant may be available. This is a mixture of collagen-derived particles and topical bovine-derived thrombin that can be used to control acute epistaxis. […] If cautery and matrix sealant (where available) have failed then nasal packing may be required. […] Cautery can also be used in the treatment of minor recurrent epistaxis which, although rarely serious, can be troublesome and affect quality of life.

  A. Bleeding from the nose (epistaxis) is a common condition and rarely serious. Most bleeds are minor and self-limiting. It is thought that approximately 60 per cent of the population will suffer from a nosebleed at some point in their lifetime. […] Despite these reassuring statistics it should be remembered that some nosebleeds can be serious and even fatal if not treated effectively. […] The main causes of epistaxis are trauma to the nose, disorders of platelet function, disorders such as hereditary haemorrhagic telangiectasia, cocaine use, some systemic conditions, such as Wegener’s granulomatosis and tumours (rare). […] Very few medicines directly cause epistaxis. Patients using topical nasal steroid sprays may be at greater risk of epistaxis through thinning of the septal mucosa, but these products rarely cause significant bleeds.

  Nosebleeds (Epistaxis) is a common condition in which there is bleeding from one or both sides of the nasal septum due to tearing of the small blood vessels that feed the septum caused by hard nasal picking, a severe impact on the nasal septum, dry nasal mucosa, or a condition in which the body’s temperature rises. […] Epistaxis or nosebleeds occurs when small blood vessels or capillaries in the nasal septum rupture or tear, leading to bleeding from one or both nostrils. […] Common conditions: Dry air due to high temperature and low relative humidity inside the living facility causes blood vessels in the nasal septum to dry out, clot, and burst when impacted. […] Certain medications, such as intranasal steroids for allergies, vasoconstrictor decongestants, and antihistamines, cause the nasal septum to dry out and bleed.

  Various medications, both prescription and over the counter can have the unwanted side effect of increasing the risk of epistaxis. Topical decongestant nasal sprays as well as those sprays used for allergies can irritate the lining of the nose and cause bleeding. This is especially true if they are used on a chronic basis, or used more frequently than recommended. Over the counter pain medications such as aspirin and ibuprofen cause problems using a different mechanism. Instead of directly damaging the lining of the nose, these medications can make the patients blood not clot as well. In this case, a small area of irritation inside the nose can be more likely to bleed and take longer to stop bleeding due to this side effect. Finally, there are some medications prescribed specifically to thin a patients blood to prevent unwanted clots from forming in the body. These will however also make it more difficult for the body to stop bleeding if a nose bleed were to start.

  Epistaxis, or nosebleed, is one of the most frequent ear, nose, and throat emergencies encountered in both primary care and emergency settings. […] Anterior nosebleeds typically arise from Kiesselbach’s plexus, located on the anterior nasal septum. […] The rupture of a blood vessel within the nasal mucosa causes nosebleeds. Rupture can be spontaneous, initiated by trauma, use of certain medications, and secondary to other comorbidities or malignancies. An increase in the patient’s blood pressure can increase the episode’s length. Anticoagulant medications, as well as clotting disorders, can also increase the bleeding time. […] Most nosebleeds occur in the anterior part of the nose (Kiesselbach plexus), and an etiologic vessel can usually be found on careful nasal examination. […] Bleeding from the posterior or superior nasal cavity is often termed a posterior nosebleed. This is usually presumed due to bleeding from the Woodruff plexus, the rear, and fine terminal branches of the sphenopalatine and posterior ethmoidal arteries.

  There are numerous causes for epistaxis to consider, including trauma, hypertension, iatrogenic (e.g. anti-coagulants), or foreign bodies (nose-picking is the most common cause in children!). Less common causes include coagulopathies, platelet disorders, vascular malformations, vasculitis, rhinosinusitis (including allergies), malignancy, or cocaine use. […] If nasal packing fails to stop the bleeding, then contributing blood vessels can either be ligated surgically or embolised radiologically. The vessels that are targeted are usually the sphenopalatine artery, anterior ethmoidal artery (never embolised due to its origin from the internal carotid artery and may lead to blindness), or the external carotid artery (as a last resort).

  https://theconversation.com/health-check-why-do-we-get-nose-bleeds-97367

  Nose bleeds, or epistaxes, are often a mystery to the 60% of us who have had at least one in our lifetime. […] The nose is very prone to bleeding. This is because of the important role it plays in warming and humidifying the air we breathe. Large numbers of small blood vessels lie just under a thin layer of skin, as a heat exchange mechanism for air going to the lungs. […] A number of things can cause those vessels to rupture and the nose to bleed. […] Nasal infections and dryness are known to increase the frequency of bleeds. In one study, people who got nose bleeds were seven times more likely to have staphylococcal bacteria in their nose than than their peers who didnt get nose bleeds. […] Depending on the location of the ruptured blood vessels, the bleed is classified as anterior (the front part of the nose) or posterior (the back part of the nose). The blood from an anterior bleed will predominantly flow out of the nostrils, while with a posterior bleed, much of the blood will end up in the throat to be spat up or swallowed.

  Any disorder that disrupts the normal healthy mucosa may induce nosebleeds; conditions include sinonasal tumors, granulomatous disease, septal perforation/ulceration, and environmental/occupational irritant exposure. […] Probably the most common predisposing factor to epistaxis is the use of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs), which are often taken as self-medication. […] Epistaxis is also listed as a side effect of many other medications. […] Hypertension is often quoted as being a cause of epistaxis, but a definite relationship has not been proven. […] HHT is a rare but significant cause of severe recurrent epistaxis that will be referred to later in this chapter. The condition is inherited as an autosomal dominant genetic disorder, leading to a weakness of blood vessel walls and vascular malformations. The underlying mechanism is not completely understood.

  Epistaxis has been categorized as primary (idiopathic) or secondary (due to an identifiable cause). It is estimated that 70% of bleeds are primary. […] Primary epistaxis refers to spontaneous idiopathic bleeding from the nose. The reason why this happens is not fully understood. However, we can hypothesize that in older people the nasal mucosa and blood vessels become more fragile and more susceptible to spontaneous bleeding. […] The introduction of endoscopes into clinical practice has led to improved recognition of the bleeding site and more accurate diagnoses. Small vascular anomalies such as hemangiomas are therefore clearly recognizable. […] Where bleeding is due to a known cause, it is termed secondary. There are many causes of secondary epistaxis, but most are posttrauma or secondary to sino-nasal surgery.

• #91 Nose Bleeds | Mass Eye and Ear

  https://masseyeandear.org/conditions/nose-bleeds

  Epistaxis or nosebleeds are very common and can occur for a variety of reasons. The inside lining of the nose has a rich blood supply, with blood vessels located very close to the surface. When these vessels break, it can cause the nose to bleed. […] When the bleeding is aggressive and persists beyond the above measures, patients should seek emergency care. In some cases, packing the nasal cavity in the emergency room setting will stop the bleeding. If that is not enough, the broken blood vessel may need to be treated. This is sometimes done through cautery, a minor procedure in which the area thats bleeding is slightly burned to block the vessel from bleeding. […] Sometimes, an operative procedure that identifies and clips the problematic blood vessel may be necessary. In rare cases, embolization is recommended to stop the bleeding, in which a radiologist will perform an angiogram and inject particles into the blood vessels. […] If you experience recurrent episodes of brisk bleeding, a specialist should evaluate you. There can be other underlying reasons for recurrent nosebleeds, such as vascular abnormalities or tumors. An endoscopic exam and CT or MRI scan may be needed to further evaluate the bleeding.

  Nosebleeds occur when the moist inner lining of the nose is irritated or when blood vessels in the nose are broken. […] Regardless of the cause, people who take aspirin or other medications that interfere with blood clotting (anticoagulants), who have a clotting disorder, or who have hardening of the arteries (arteriosclerosis) are more likely to develop nosebleeds. […] Posterior nosebleeds usually involve larger blood vessels than anterior nosebleeds. […] Anterior nosebleeds usually come from the front part of the nose (anterior nosebleed). The bleeding comes from small blood vessels in the cartilage that separates the two nostrils (called the nasal septum). […] High blood pressure (hypertension) is unlikely to cause a nosebleed, but in people with high blood pressure, the nosebleed may last longer than expected. […] For more severe or recurring bleeding, sometimes the doctor seals (cauterizes) the bleeding source with a chemical, silver nitrate, or an electrical current (electrocautery). […] If the balloon or packing does not work, doctors need to directly close the bleeding vessel.

  “Blood thinning” or anticoagulant medicines such as aspirin, clopidogrel and warfarin do not cause nosebleeds themselves but, by reducing the blood’s ability to clot, can prolong bleeds, making them heavier and more clinically significant. […] The association between hypertension and epistaxis is probably a myth. Although it is common for patients to be hypertensive when they present with nosebleeds this has been attributed to stress, anxiety etc. […] If cautery fails to stop bleeding, or a bleeding point cannot be accessed with a cauterising device, in some areas a matrix sealant may be available. This is a mixture of collagen-derived particles and topical bovine-derived thrombin that can be used to control acute epistaxis. […] If cautery and matrix sealant (where available) have failed then nasal packing may be required. […] Cautery can also be used in the treatment of minor recurrent epistaxis which, although rarely serious, can be troublesome and affect quality of life.

  Some Studies: Indicate a higher prevalence of hypertension in patients with epistaxis, suggesting a potential link between high blood pressure and severity of nosebleeds. […] In conclusion, while hypertension is commonly associated with epistaxis, its role as a direct cause remains uncertain. The elevated blood pressure observed in many patients with epistaxis may be a result of the stress and anxiety related to the bleeding rather than the underlying cause. However, given the potential for vascular fragility and the effects of hypertensive medications, managing hypertension is a crucial component in the comprehensive care of patients with recurrent or severe epistaxis. Further research is needed to elucidate the precise mechanisms linking hypertension and epistaxis, which will help improve prevention and treatment strategies for affected individuals.

  Self-mutilation is defined as a deliberate act of destruction and/or body alteration without suicidal intent and is noted to occur in a wide variety of psychiatric conditions. […] The management would initially be surgical management of the traumatic facial injury but with the addition of psychiatric referral and/or transfer of care to manage the underlying psychiatric condition. […] A patient that presents with an inanimate nasal foreign body typically reports painless, unilateral mucopurulent discharge. Epistaxis is rare but has been reported in the literature. […] A factitious disorder is a psychiatric condition in which the patient intentionally fabricates physical and/or psychological symptoms solely to assume the role of a patient. […] Psychogenic purpura, also known as Gardner-Diamond Syndrome, is a rare condition that presents as spontaneous painful ecchymosis following severe stress and/or emotional trauma.

• #105 Nosebleeds (Epistaxis): Causes, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/13464-nosebleed-epistaxis

  Nosebleeds have many causes, including dry air, allergies and recreational drug use. […] Less common causes of nosebleeds include alcohol use, bleeding disorders, like hemophilia or von Willebrand disease, high blood pressure, atherosclerosis, facial and nasal surgery, nasal tumors, nasal polyps, immune thrombocytopenia, leukemia, hereditary hemorrhagic telangiectasia, and pregnancy. […] The reasons for nosebleeds during sleep are the same as the reasons why they occur during the day. Dry air, allergies and upper respiratory infections damage the delicate nasal membrane lining your nose. […] Nosebleed treatment depends on the cause of the bleeding. Your provider will explain what’s necessary in your situation. Epistaxis treatment may include nasal packing, cauterization, medication adjustments/new prescriptions, foreign body removal, surgery, and ligation. […] Nosebleeds that occur higher on your septum or deeper in your nose may be harder to control. However, nosebleeds are rarely fatal.

  An increase in blood pressure (e.g. due to general hypertension) tends to increase the duration of spontaneous epistaxis. […] Anticoagulant medication and disorders of blood clotting can promote and prolong bleeding. […] Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nosebleeds as their blood vessels are less able to constrict and control the bleeding. […] The vast majority of nosebleeds occur in the front anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach’s plexus). This region is also known as Little’s area. Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff’s plexus, a venous plexus situated in the posterior part of inferior meatus.

  Many women experience nosebleeds during pregnancy due to hormonal changes and increased blood flow placing greater pressure on the delicate blood vessels in the lining of the nose. […] Adults with HHT have some blood vessels that haven’t developed properly causing frequent nose bleeding or arteriovenous malformations (AVMs). […] People with high blood pressure who consume excessive amounts of alcohol are more likely to suffer from nose bleeds. […] Patients who have recently undergone surgery on their nose (i.e. rhinoplasty, septoplasty, or septorhinoplasty) may experience bleeding usually as a result of the incisions made, use of blood thinners, or outside impacts. […] In most cases, frequent epistaxis (the medical term for recurring nosebleeds) is caused by the rupture of the blood vessels in the nose or an abnormal growth (tumour or polyp) in the nose or sinuses.

• #109 Nosebleed Causes and Treatments – familydoctor.org

  https://familydoctor.org/condition/nosebleeds/

  A nosebleed is blood loss from the tissue that lines your nose. It can affect both nostrils, but most often occurs in only one nostril. Usually, a nosebleed is not serious. […] Sometimes, though, nosebleeds are more serious. These stem from large vessels in the back of the nose. Nosebleeds from these larger vessels often occur after an injury, in young children, or in the elderly. Usually, the older the patient, the more serious the nosebleed. […] Less common causes include injuries, allergies, or the use of illegal drugs, such as cocaine. Children may stick small objects up their noses, and that can cause the nose to bleed. Older people may have atherosclerosis (which is the hardening of the arteries), infections, high blood pressure, or blood clotting disorders that may cause nosebleeds. Nosebleeds may occur and last longer if you’re taking drugs that interfere with blood clotting, such as aspirin. A rare cause of frequent nosebleeds is a disorder called hereditary hemorrhagic telangiectasia (HHT). Sometimes, the cause of nosebleeds can’t be determined. […] Frequent nosebleeds may mean you have a more serious problem. For example, nosebleeds and bruising can be early signs of leukemia. Nosebleeds can also be a sign of a blood clotting or blood vessel disorder, or a nasal tumor (both non-cancerous and cancerous).

  Epistaxis associated with hypertension in elderly becomes difficult to control at times. […] As per available literature, posterior nasal packing are commonly used in the management of epistaxis with hypertension. […] In our series use of either anterior nasal packing or merocele application was done in the majority (87%) of the cases for the initial control of the bleeding and few required posterior nasal packing. […] Chronic rhinosinusitis also gives rise to epistaxis in the elderly, as recorded (4%) in this study. Initial control of bleeding with merocele application or nasal packing followed by control of infection was the protocol followed in the management of our cases as per the records in this retrospective study. […] Epistaxis poses a greater risk in elderly in whom clinical deterioration progresses rapidly with significant blood loss. […] A comprehensive management of the underlying cause, is necessary to reduce the morbidity associated with epistaxis in the elderly.

  Epistaxis, or nasal bleeding, has been reported to occur in up to 60 percent of the general population. The condition has a bimodal distribution, with incidence peaks at ages younger than 10 years and older than 50 years. Epistaxis appears to occur more often in males than in females. […] Most causes of nasal bleeding can be identified readily through a directed history and physical examination. The patient should be asked about the initial presentation of the bleeding, previous bleeding episodes and their treatment, comorbid conditions, and current medications, including over-the-counter medicines and herbal and home remedies. […] Although the differential diagnosis should include both local and systemic causes, environmental factors such as humidity and allergens also must be considered.

  Epistaxis, commonly known as a nosebleed, refers to bleeding from tissues inside the nose caused by broken blood vessels. […] Frequent epistaxis is most often caused by capillaries inside the nose that are irritated and wont heal properly. […] Frequent epistaxis may require intervention from an otolaryngologist, a medical professional commonly known as an Ear, Nose, and Throat (ENT) doctor. […] Your ENT physician may use a thin, long camera called a nasal endoscope to examine the inside of your nose to determine the source and severity of the bleeding. […] Once your ENT identifies the source and cause of the bloody nose, he or she will present the patient with treatment options. Treatment may include: the adjustment of medications, retrieval of foreign bodies that may have been stuck up the nose, surgery (when dealing with a deviated septum or broken nose), treatment to stem the bleeding, such as nasal packing or cauterizing the nose.

  Several things can cause nosebleeds. The most common cause is irritation or damage to the lining inside of the nose. This can be caused by dry air, trauma, or misusing nasal sprays. […] In some cases, nosebleeds can be a symptom of an underlying medical condition, such as blood clotting disorders (hemophilia or hereditary hemorrhagic telangiectasia) or nasal tumors. […] If these methods dont work, your doctor may use sticks coated with a chemical called silver nitrate to cauterize (or burn) the blood vessels shut. They may also use electrical cautery in some instances. Another way to control nose bleeds is packing the nose. […] If the nosebleed is more complicated, your doctor may recommend a procedure called embolization to block off a blood vessel using a special material. Another option is surgery, which may involve endoscopically tying off or cauterizing a bigger blood vessel in the nose.

• #129 Nosebleed Causes and Treatments – familydoctor.org

  https://familydoctor.org/condition/nosebleeds/

  A nosebleed is blood loss from the tissue that lines your nose. It can affect both nostrils, but most often occurs in only one nostril. Usually, a nosebleed is not serious. […] Sometimes, though, nosebleeds are more serious. These stem from large vessels in the back of the nose. Nosebleeds from these larger vessels often occur after an injury, in young children, or in the elderly. Usually, the older the patient, the more serious the nosebleed. […] Less common causes include injuries, allergies, or the use of illegal drugs, such as cocaine. Children may stick small objects up their noses, and that can cause the nose to bleed. Older people may have atherosclerosis (which is the hardening of the arteries), infections, high blood pressure, or blood clotting disorders that may cause nosebleeds. Nosebleeds may occur and last longer if you’re taking drugs that interfere with blood clotting, such as aspirin. A rare cause of frequent nosebleeds is a disorder called hereditary hemorrhagic telangiectasia (HHT). Sometimes, the cause of nosebleeds can’t be determined. […] Frequent nosebleeds may mean you have a more serious problem. For example, nosebleeds and bruising can be early signs of leukemia. Nosebleeds can also be a sign of a blood clotting or blood vessel disorder, or a nasal tumor (both non-cancerous and cancerous).

  https://www.health.harvard.edu/a_to_z/nosebleed-epistaxis-a-to-z

  The inside of the nose is covered with moist, delicate tissue (mucosa) that has a rich supply of blood vessels near the surface. When this tissue is injured, even from a minor nick or scratch, these blood vessels tend to bleed, sometimes heavily. […] Only rarely is a nosebleed life threatening or fatal. In these cases, the hemorrhage (severe bleeding) is usually from an artery in a posterior location, higher and deeper in the nose. […] In most cases of severe nosebleeds, the person has another health problem, such as high blood pressure or a bleeding disorder, or the person takes a blood-thinning medication that slows down the blood-clotting process. […] Certain people are more likely to get nosebleeds because of their environment, work history, health problems or use of medications that increase the tendency to bleed.

  Initial management includes compression of the nostrils (application of direct pressure to the septal area) and plugging of the affected nostril with gauze or cotton that has been soaked in a topical decongestant. […] Every attempt should be made to locate the source of bleeding that does not respond to simple compression and nasal plugging. […] If a single anterior bleeding site is found, vasoconstriction should be attempted with topical application of a 4 percent cocaine solution or an oxymetazoline or phenylephrine solution. […] Larger vessels generally respond more readily to electrocautery. […] If local treatments fail to stop anterior bleeding, the anterior nasal cavity should be packed, from posterior to anterior, with ribbon gauze impregnated with petroleum jelly or polymyxin B-bacitracin zinc-neomycin ointment. […] Posterior bleeding is much less common than anterior bleeding and usually is treated by an otolaryngologist.

[…] It’s important to note that if someone is on prescription blood thinners, their risk of a continued hemorrhage increases significantly, as these medications can intensify bleeding and challenge the standard control techniques. […] One common misconception is to pack the nose with gauze or tissue. This should be avoided in a first-aid scenario. […] Nosebleeds are the most common sign of HHT, resulting from small abnormal blood vessels within the inside layer of the nose. While rare, it’s important to understand that sometimes a nosebleed is a sign of a greater underlying problem.

  Epistaxis or nosebleed in common parlance occurs in more than half of the population and accounts for approximately 0.5 percent of emergency department visits. […] Recurrent nosebleeds can often be managed by simply holding pressure on the nose. In some cases medical or surgical intervention is necessary, notes Dr. Gudis. In rare cases, very severe or frequent unilateral nosebleeds could warrant concern for a more serious condition, such as a benign or malignant neoplasm of the nasal cavity, sinuses, or skull base. […] The mucosa overlying the vessels in the anterior nasal cavity is thin and prone to injury. Cold, dry air and recurrent trauma commonly instigate bleeding from the anterior nasal cavity. […] Even though it’s essentially unnoticeable to the average person, over time it can cause trauma to the mucous membrane that covers Kiesselbachs plexus and cause recurrent nosebleeds.

[…] If a single anterior bleeding site is found, vasoconstriction should be attempted with topical application of a 4 percent cocaine solution or an oxymetazoline or phenylephrine solution. […] Larger vessels generally respond more readily to electrocautery. […] If local treatments fail to stop anterior bleeding, the anterior nasal cavity should be packed, from posterior to anterior, with ribbon gauze impregnated with petroleum jelly or polymyxin B-bacitracin zinc-neomycin ointment. […] Posterior bleeding is much less common than anterior bleeding and usually is treated by an otolaryngologist. […] Patients with anterior or posterior bleeding that continues despite packing or balloon procedures may require treatment by an otolaryngologist.

  If it was a septum bleed, like from the structure that we talked about, we take a look in the nose. […] The location is the most important, the etiology and the location, I would say. […] The good news is, nosebleeds rarely require… As we said, only .5% ER visit and .2% hospitalization. […] I would be concerned in patients who are like older patients with posterior nosebleeds that did not seek care and it continues to bleed, obviously. […] What I recommend if patients, obviously, are at-risk of nosebleeds is to have a humidifier at home that could obviously decrease the dryness. […] Most important is, as we said, the most common are the spontaneous anterior bleeds mostly due to dryness and obviously colder temperature.

  The second peak is in the over-65 age group, where the nose bleed may be more severe. […] In this group, nose bleeds may be indicative of a more serious health problem such as bleeding disorders and chronic sinus infections. […] Bleeding due to blood thinning medication, or sometimes as a side effect of nasal steroid sprays, are becoming more common. […] Bleeding from the back of the nose, while less common overall, is more likely to occur in older people. […] The risk of death from nose bleeds is extremely low. Out of 2.4 million deaths in the US in 1999, four were due to nose bleeds. […] If you have recurrent minor bleeds, try nasal decongestant sprays or nasal lubricants such as petroleum jelly (Vaseline). […] The other approach is to seal the bleeding vessels with chemical (such as silver nitrate applicators) or heat cauterisation.

  Repeated nosebleeds may be a symptom of another disease such as high blood pressure, a bleeding disorder, or a tumor of the nose or sinuses. Blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, may cause or worsen nosebleeds. […] The type of treatment used will be based on the cause of the nosebleed. Treatment may include: controlling blood pressure, closing the blood vessel using heat, electric current, or silver nitrate sticks, nasal packing, reducing a broken nose or removing a foreign body, reducing the amount of blood thinner medicine or stopping aspirin, treating problems that keeps your blood from clotting normally.

  In the event of severe epistaxis, embolization may be recommended. This minimally invasive treatment, performed by an experienced interventional radiologist under local or general anesthesia, consists in blocking the culprit blood vessels by introducing an embolic agent in the form of small spheres. These spheres block the blood vessels and halt the flow of blood. […] According to recent studies, this procedure is a safe and effective treatment for persistent nosebleeds. In 2023, a meta-analysis of 41 studies involving 1,632 patients showed an average immediate success rate of 90.9% and an average recurrence rate of 17%. Major complications are very rare; minor complications are more frequent but temporary (nasal pain, headaches, hematoma at the insertion site).

  There are numerous causes for epistaxis to consider, including trauma, hypertension, iatrogenic (e.g. anti-coagulants), or foreign bodies (nose-picking is the most common cause in children!). Less common causes include coagulopathies, platelet disorders, vascular malformations, vasculitis, rhinosinusitis (including allergies), malignancy, or cocaine use. […] If nasal packing fails to stop the bleeding, then contributing blood vessels can either be ligated surgically or embolised radiologically. The vessels that are targeted are usually the sphenopalatine artery, anterior ethmoidal artery (never embolised due to its origin from the internal carotid artery and may lead to blindness), or the external carotid artery (as a last resort).

  Most nasal bleeding is anterior, originating from a plexus of vessels in the anteroinferior septum (Kiesselbach area). […] Less common but more serious are posterior nosebleeds, which originate in the posterior septum overlying the vomer bone or laterally from the inferior or middle turbinate. Posterior nosebleeds tend to occur in patients who have preexisting atherosclerotic vessels or bleeding disorders and have had nasal or sinus surgery. […] Hypertension may contribute to the persistence of a nosebleed that has already begun but is unlikely to be the sole etiology. […] Many cases of epistaxis have a clear-cut trigger (particularly nose blowing or picking), as suggested by findings. […] In hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome), a split-thickness skin graft (septal dermatoplasty) reduces the number of nosebleeds and allows the anemia to be corrected.

  The use of anticoagulant medications such as warfarin or heparin in patients with heart disease. […] Abnormal conditions or diseases including: Clotting disorders such as hemophilia. […] A thorough evaluation of epistaxis from an ear, nose, and throat specialist can promptly pinpoint underlying diseases causing the epistaxis. […] If the epistaxis or nosebleed persists, the patient should seek treatment at a hospital as soon as possible to avoid shock and unconsciousness from blood loss. […] The otolaryngologist can choose among the following treatments: Topical decongestants apply to the nasal septum. […] Cauterization with chemicals such as silver nitrate or thermal energy, such as electrocautery, to seal the bleeding blood vessel. […] Internal artery ligation: In some cases, the doctor may decide on internal artery ligation or artery occlusion to stop bleeding by using an occlusive tube with nasal endoscopy to tie off a blood vessel to stop bleeding.

  Some medications contain anticoagulants. Therefore, in patients with congenital diseases, the otolaryngologist may consider adjusting the existing medications or using a new drug to help control blood pressure, or prescribing an anticoagulant, such as Tranexamic, to help with the blood clot. […] Many epistaxes are caused by children accidentally putting toys or foreign objects into their noses, resulting in nosebleeds.
