  https://www.ncbi.nlm.nih.gov/books/NBK448124/

  Acute compartment syndrome is considered a surgical emergency since, without proper treatment, it can lead to ischemia and eventually necrosis. Generally, acute compartment syndrome is considered a clinical diagnosis. However, intracompartmental pressure (ICP) 30 mmHg can be used as a threshold to aid in diagnosis. However, a single normal ICP reading does not exclude acute compartment syndrome. […] Acute compartment syndrome is a clinical diagnosis and needs prompt treatment. However, the following are done to evaluate further and to confirm the diagnosis. […] Measurement of intracompartmental pressure is not required but can aid in diagnosis if uncertainty exists. Compartment pressures are often measured with a manometer, a device that detects intracompartmental pressure by measuring the resistance that is present when a saline solution is injected into the compartment. Another method employs a slit catheter, whereby a catheter is placed within the compartment, and the pressure is measured with an arterial line transducer. The slit catheter method is more accurate and allows for continuous monitoring. Its use is also recommended to measure all the surrounding compartments.

  https://www.uptodate.com/contents/acute-compartment-syndrome-of-the-extremities

  Acute compartment syndrome (ACS) of an extremity is diagnosed on the basis of the history, examination findings, and often the measurement of compartment pressures, although this is not required. ACS most often develops soon after significant trauma, particularly involving long bone fractures. Other possible causes include crush injury, severe thermal burns, penetrating trauma, injury to vascular structures, and less often a number of nontraumatic conditions. Important clues to the development of ACS include rapid progression of symptoms and signs over a few hours and the presence of multiple findings consistent with the diagnosis in a patient at risk. Notable findings include pain out of proportion to apparent injury, pain with passive stretch of muscles in the affected compartment, and a tense compartment with a firm „wood-like” feeling. In patients with suggestive clinical features, a difference between the diastolic blood pressure and the compartment pressure (delta pressure) of 30 mmHg or less strongly suggests the diagnosis of ACS. A table outlining the emergency evaluation and management of ACS is provided (table 1).

  Compartment syndrome is typically identified via clinical diagnosis based on symptoms and risk factors, as prompt treatment is crucial (Torlincasi et al. 2022; TeachMe Surgery 2022). […] Physical examination should involve: Assessing the skin for lesions, swelling or discolouration, Palpating the compartment to assess temperature, tension and tenderness, Checking the patients pulse, A two-point discrimination test, which is used to assess whether the patient can identify that two objects touching the skin close together are separate objects rather than one, Assessing motor function. […] Traditionally, compartment syndrome has been diagnosed using the 'six Ps of arterial insufficiency: Pain, Pulselessness, Paraesthesia, Paralysis, Pallor, Poikilothermia. […] The six Ps are now considered clinically unreliable as aside from pain, they may only occur in the later stages of compartment syndrome by the time irreversible tissue damage has already occurred (Rasul Jr 2020; Hammerberg 2022).

  What happens if you combine signs and symptoms? A combination of pain with passive stretch, pain at rest, and paresthesias has a sensitivity of 93 percent for diagnosis, and the addition of paresis increases sensitivity to 98 percent. However, do not rely on the absence of any classic isolated findings. Other items that complicate diagnosis based on history and exam include clinician inexperience, sedation, polytrauma, and intoxication. […] What about other tools? Abnormal pulse oximetry may indicate compartment syndrome. However, you cannot use this to exclude the condition. Rhabdomyolysis is present in up to 40 percent of patients with compartment syndrome, so be sure to check creatine kinase levels, renal function, and electrolytes. […] The most reliable bedside data can be obtained by measuring intracompartmental pressure. Options include a solid-state transducer intracompartmental catheter (STC) device (eg, a Stryker monitor) or other needle manometer/arterial line setups. The Stryker monitor has a diagnostic sensitivity around 95 percent, with specificity greater than 98 percent. Make sure to place the catheter within 5 cm of the fracture/injury level. However, the catheter tip should be outside the actual site of the fracture. Also ensure the pressure transducer and catheter tip are at the same height.

  An intra-compartmental pressure greater than 30 mmHg indicates compartment syndrome and a need for fasciotomy. […] If ICP is greater than or equal to 30 mmHg or delta pressure is less than or equal to 30 mmHg, fasciotomy should be done. […] Acute compartment syndrome is a surgical emergency, so prompt diagnosis and treatment are critical. Once the diagnosis is confirmed, immediate surgical fasciotomy is needed to reduce the intracompartmental pressure. The ideal timeframe for fasciotomy is within six hours of injury, and fasciotomy is not recommended after 36 hours following injury.

  The accuracy of the physical examination for diagnosing ACS is limited. Early symptoms include progressive pain out of proportion to the injury; signs include tense swollen compartments and pain with passive stretching of muscles within the affected compartment. Important clues include rapid progression of symptoms and signs over a few hours and the presence of multiple findings consistent with the diagnosis in a patient at risk. Close observation and serial examinations are of great importance. Motor deficits are LATE findings associated with irreversible muscle and nerve damage. […] Immediate surgical consultation should be obtained whenever ACS is suspected based upon the patient’s risk factors and clinical findings. Whenever possible, the surgeon should determine the need for measuring compartment pressures, which can aid diagnosis. A single normal compartment pressure reading, which may be performed early in the course of the disease, does not rule out ACS. Serial or continuous measurements are important when patient risk is moderate to high or clinical suspicion persists.

  Compartment syndrome is a painful condition that occurs when pressure within the muscles builds to dangerous levels. This pressure can decrease blood flow, which prevents nourishment and oxygen from reaching nerve and muscle cells. […] Compartment syndrome can be either acute (having severe symptoms for a short period of time) or chronic (long-lasting). […] Acute compartment syndrome is a medical emergency. It is usually caused by a severe injury and is extremely painful. Without treatment, it can lead to permanent muscle damage. […] Chronic compartment syndrome, also known as exertional compartment syndrome, is usually not a medical emergency. It is most often caused by athletic exertion and is reversible with rest. […] Compartment syndrome develops when swelling or bleeding occurs within a compartment. Because the fascia does not stretch, this can cause increased pressure on the capillaries, nerves, and muscles in the compartment. Blood flow to muscle and nerve cells is disrupted. Without a steady supply of oxygen and nutrients, nerve and muscle cells can be damaged.

  Despite there is obvious evidence that delay in treatment leads to poorer outcomes, it is difficult to determine the exact time of performance for fasciotomy. […] The main etiologies of ACS was traumatic injuries such as fracture and crush-type injury, while other injuries such as limb ischemia (ischemia-reperfusion injury after revascularization), tourniquet, tight splint, shock trousers, drug injection, or snake bites could also induce ACS. […] The most important thing to treat ACS was comprehension to the true injury mechanism, but a systemic classification about traumatic mechanism in most literature was not clear. […] Although fasciotomy is considered as the gold standard for ACS, but the role of fasciotomy in the treatment of crush syndrome is still controversial. […] The ACS was always found to be mixed with the concept of crushing syndrome and Volkmann contracture. […] The consequences of missed diagnosis are severe for both patients and surgeons. […] The ACS is considered as an orthopedic emergency which can lead to limb and life-threatening outcome if there is delay in diagnosis and treatment.

  Compartment syndrome is a clinical diagnosis, based on the symptoms and risk factors present. Clinicians should therefore have a high degree of clinical suspicion for compartment syndrome in post-operative patients. […] The most reliable diagnostic test is siting an intra-compartmental pressure monitor, which may be utilised where there is clinical uncertainty, such as in atypical presentations or if the patient is unconscious / intubated (normal compartmental pressures are 0-8mm Hg). […] A creatine kinase (CK) level may aid diagnosis, if elevated (or trending upwards). […] Diagnosis is clinical, the main symptom being pain disproportionate to the injury or worsening despite treatment.

  First and foremost, however, compartment syndrome remains a clinical diagnosis. Objective confirmation is reassuring but waiting for that evidence must not create an unacceptable delay. […] In cases in which the patient is unable to participate in the exam, compartment pressures can be measured using needle manometry. […] Although it has been suggested that a given value for compartment pressure can be used to make the diagnosis, the best criterion for the diagnosis is the pressure differential between the mean arterial blood pressure and the measured compartment pressure. […] A commonly used consensus criterion is that if the difference is less than 40 mm Hg, perfusion will be impaired. […] In a patient that is intubated and sedated, it is not possible to gather a clinical history or perform an exam. Therefore, any injury classically associated with compartment syndrome should result in a low threshold to measure the compartment pressure in order to obtain a diagnosis.

  https://pmc.ncbi.nlm.nih.gov/articles/PMC3535085/

  Acute compartment syndrome (ACS) is a surgical emergency. Diagnosis depends on a high clinical suspicion and an understanding of risk factors, pathophysiology and subtle physical exam findings. […] Diagnosis of ACS in this patient is primarily a clinical one but can be confirmed with invasive intracompartmental pressure monitoring or non-invasive near infrared spectroscopy (NIRS). […] The diagnosis of compartment syndrome is often based on subtle changes in symptoms and vague clinical exam findings. […] Overall, the absence of symptoms is more useful in excluding ACS, than the presence of symptoms is in to diagnosing ACS. […] ICP monitoring is a controversial component in evaluating the patient with suspected ACS. […] In the awake and alert patient, compartment syndrome can be diagnosed based on clinical signs and symptoms with or without confirmatory intracompartmental pressure data. […] Clinical compartment monitoring is highly variable across examiners and is not always reliable in the diagnosis of ACS. […] NIRS has been validated in humans as a noninvasive, continuous technique to evaluate tissue oxygenation.

  Compartment syndrome is increased tissue pressure within a closed fascial space, resulting in tissue ischemia. Diagnosis is clinical and usually confirmed by measuring compartment pressure. […] Diagnosis of compartment syndrome must be made and treatment started before pallor or pulselessness develops, indicating necrosis. […] Thus, in patients with at-risk injuries, clinicians must have a low threshold for measuring compartment pressure (normal 8 mm Hg), usually with a commercially available pressure monitor. Compartment syndrome is confirmed if compartmental pressure is more than approximately 30 mm Hg or within approximately 30 mm Hg of diastolic blood pressure (BP). […] Measure compartment pressure to confirm the diagnosis; a finding of more than approximately 30 mm Hg or within approximately 30 mm Hg of diastolic BP confirms it.

  Patients with compartment syndrome typically present with pain whose severity appears out of proportion to the injury. The pain is often described as burning. The pain is also deep and aching in nature and is worsened by passive stretching of the involved muscles. The patient may describe a tense feeling in the extremity. Pain, however, should not be a sine qua non of the diagnosis. In severe trauma, such as an open fracture, it is difficult to differentiate between pain from the fracture and pain resulting from increased compartment pressure.

  After obtaining the intracompartmental pressure, you can use an absolute intracompartmental pressure of 30-40 mm Hg as diagnostic, but using a true intracompartmental pressure alone is problematic, as different compartments have varying pressure thresholds and patients may have varying absolute pressures. Some advocate using a perfusion pressure or differential pressure, which is calculated by subtracting the intracompartmental pressure from the diastolic pressure. A differential pressure (P = compartmental pressure – diastolic blood pressure) of 20 mm Hg is diagnostic. While higher intracompartmental pressures can cause severe damage over a short time period, relatively lower but elevated intracompartmental pressures for long time periods can also cause severe tissue damage. Also, an absolute intracompartmental pressure >20 mm Hg in the setting of hypotension should be considered diagnostic. If the initial pressure is normal but the clinical picture fits compartment syndrome, a repeat measurement as well as pressure measurements in surrounding compartments are recommended.

  The most reliable diagnostic method for compartment syndrome is measuring the intracompartmental pressure (ICP) of the affected area using a manometer or slit catheter. […] An ICP of over 30 mmHg indicates compartment syndrome (normal pressure is between 0 mmHg and 8 mmHg) (Torlincasi et al. 2022). […] Other diagnostic tests that might be used include: Radiograph if the patient has a suspected fracture, Doppler ultrasound to assess for occlusion or thrombus, Creatine kinase (CK) blood test (elevated CK levels are indicative of compartment syndrome), Complete blood count and coagulation studies (preoperatively). […] Note: Due to the severity of the condition and the potential for limb loss, treatment should be prioritised with less time spent on confirming the diagnosis (Torlincasi et al. 2022).

  On the way to pain-free diagnosis of compartment syndrome. The diagnosis of compartment syndrome is difficult to make. It is mainly based on the symptoms of the affected person, first and foremost severe pain and numbness or tingling in the fingers or toes. […] For this reason, the role of regional anaesthesia in delaying the diagnosis of compartment syndrome is being discussed. […] In a project funded by the FWF, scientists headed by Priv. Doz. Dr. Gerhard Fritsch, senior physician at the AUVA emergency hospital Salzburg, are specifically investigating the question of how regional anaesthesia affects the formation and recognition of compartment syndrome. […] The research project also uses a new diagnostic method. The so-called microperfusion makes it possible to measure substances directly in the muscle tissue, i.e. directly at the site of the event, which are produced in the course of cell death.

  Other exercise-related problems are more common than chronic exertional compartment syndrome, so your doctor may first try to rule out other causes such as shin splints or stress fractures before moving on to more specialized testing. […] Results of physical exams for chronic exertional compartment syndrome are often normal. Your doctor might prefer to examine you after you’ve exercised to the point of bringing on symptoms. Your doctor may notice a muscle bulge, tenderness or tension in the affected area. […] Imaging studies may include: […] A typical MRI scan of your legs can be used to evaluate the structure of the muscles in the compartments and rule out other possible causes of your symptoms. […] An advanced MRI scan can help assess the fluid volumes of the compartments. Images are taken at rest, while moving your foot until you feel symptoms, and after the exercise.

  How useful are historical features? Unfortunately, early findings can be subtle or not detected in patients with altered mental status, major trauma, substance use, and extremes of age. Classically, the earliest symptom is pain out of proportion to the exam (as with other conditions including necrotizing fasciitis and mesenteric ischemia). Patients typically describe this pain as a deep, severe pain that worsens with passive stretch. While this seems relatively straightforward, data suggest that severe pain has poor sensitivity, as pain is typically subjective. If ischemia develops, pain may vanish with necrosis. Other late symptoms include sensory changes/paresthesias and focal motor deficits. […] Is your bedside exam reliable? While we are taught about the classic findings of pain with passive stretch, a tense/firm compartment, swelling, focal motor/sensory changes, and decreased pulses, these are not always present and have poor sensitivity. Digital palpation has a sensitivity under 50 percent for detection of compartment syndrome affecting the hand and under 25 percent for the leg. Paralysis and absent pulses are rare, and palpating a tense or firm compartment is not reliable. Swelling of the affected area may be present in only half of patients.

  Compartment syndrome is generally an orthopedic emergency, and because the consequences are often dire, there is a high risk for medical malpractice. […] To date, there are no reliable clinical guidelines established to diagnose compartment syndrome. It can be difficult to diagnose due to similarity between its side effects and side effects of other conditions. […] Compartment syndrome that occurs after an injury is called acute compartment syndrome (ACS), but it can also occur from overuse of a muscle, called chronic exertional compartment syndrome, which typically affects athletes. […] According to the BMJ, lower extremity compartment syndrome is a devastating complication if not rapidly diagnosed and properly managed. […] If the fasciotomy is delayed, muscle tissue may die and the patient may require amputation of the limb. […] Chronic compartment syndrome is easier to diagnose because it develops over a longer period of time.

  A clinical diagnosis of compartment syndrome can be followed by prompt surgical decompression; however, the diagnosis is often unclear, and pressure monitoring is commonly required. […] For both evaluable and non-evaluable patients, pressure measurement is invaluable in the diagnosis of compartment syndrome. […] Traditionally, an intramuscular compartment pressure of 30mm Hg was used as a diagnostic threshold for diagnosing compartment syndrome, although the absolute pressure value has been debated. […] Tissue perfusion pressure, or delta pressure, which is calculated as diastolic blood pressure minus the compartment pressure, has been studied as an alternative trigger for compartment release. […] Continuous compartment pressure monitoring has been suggested as an alternative to spot compartment pressure checks.

  Although diagnosing acute compartment syndrome (CS) can be difficult, both patients in these cases displayed typical symptoms of CS involving lower extremity fractures: development of severe worsening pain and neurologic deficits (i.e., numbness and weakness). […] The resolution of pain was misleading and insufficient to exclude CS. […] Pain out of proportion to injury severity is a hallmark sign of CS and should have been investigated prior to discharge. […] Compartment fullness or firmness can be a manifestation of increased pressure and an early sign of CS; it can be assessed regardless of a patients mental status or ability to sense pain. […] Severe pain out of proportion to the patients injury and pain that does not improve with appropriate analgesia are also concerning signs of CS, although they may be confounded by opioid treatment.

  Acute compartment syndrome is considered a surgical emergency since, without proper treatment, it can lead to ischemia and eventually necrosis. Generally, acute compartment syndrome is considered a clinical diagnosis. However, intracompartmental pressure (ICP) 30 mmHg can be used as a threshold to aid in diagnosis. However, a single normal ICP reading does not exclude acute compartment syndrome. […] Acute compartment syndrome is a clinical diagnosis and needs prompt treatment. However, the following are done to evaluate further and to confirm the diagnosis. […] Measurement of intracompartmental pressure is not required but can aid in diagnosis if uncertainty exists. Compartment pressures are often measured with a manometer, a device that detects intracompartmental pressure by measuring the resistance that is present when a saline solution is injected into the compartment. Another method employs a slit catheter, whereby a catheter is placed within the compartment, and the pressure is measured with an arterial line transducer. The slit catheter method is more accurate and allows for continuous monitoring. Its use is also recommended to measure all the surrounding compartments.

  Acute compartment syndrome (ACS) is a painful condition caused by pressure within a closed osteofascial compartment. […] Compartment syndrome results when increased pressure within one of the body’s anatomical compartments results in insufficient blood supply to the tissues and leads to ischaemic necrosis of the tissues. […] Intra compartmental pressure monitoring is recommended for patients at high risk, given the documented high estimated sensitivity (94%) and specificity (98%) for the diagnosis of ACS when using a slit catheter technique and a differential pressure threshold of 30 mmHg for more than 2 hours. […] Delta pressure 30 mmHg is a better indicator of compartment syndrome than absolute compartment pressure. […] In suspected compartment syndrome, the pressure should be measured as close to the fracture site as is practicable. […] High index of suspicion is needed to diagnose this early.

  What happens if you combine signs and symptoms? A combination of pain with passive stretch, pain at rest, and paresthesias has a sensitivity of 93 percent for diagnosis, and the addition of paresis increases sensitivity to 98 percent. However, do not rely on the absence of any classic isolated findings. Other items that complicate diagnosis based on history and exam include clinician inexperience, sedation, polytrauma, and intoxication. […] What about other tools? Abnormal pulse oximetry may indicate compartment syndrome. However, you cannot use this to exclude the condition. Rhabdomyolysis is present in up to 40 percent of patients with compartment syndrome, so be sure to check creatine kinase levels, renal function, and electrolytes. […] The most reliable bedside data can be obtained by measuring intracompartmental pressure. Options include a solid-state transducer intracompartmental catheter (STC) device (eg, a Stryker monitor) or other needle manometer/arterial line setups. The Stryker monitor has a diagnostic sensitivity around 95 percent, with specificity greater than 98 percent. Make sure to place the catheter within 5 cm of the fracture/injury level. However, the catheter tip should be outside the actual site of the fracture. Also ensure the pressure transducer and catheter tip are at the same height.

  Major consequences can occur much faster than in O’Brien’s case. In fact, muscle necrosis can occur in as little as three hours after the injury in up to 37% of patients with acute compartment syndrome. Amputation was found to occur in 9.5% of acute leg compartment syndrome patients, and death occurred in 6.6%, according to a 2019 study. […] Prompt diagnosis is key as acute compartment syndrome requires emergency fasciotomy. Typically, clinical symptoms known as “The Five Ps” (pain, pulselessness, paresthesia, paralysis, and pallor) can adequately diagnose the syndrome in trauma patients with extremity injuries. […] Yet there are some instances when diagnosis is not as straightforward. For instance, a patient may be unconscious and unable to report pain or paresthesia, and there may be times when there is a high clinical suspicion of acute compartment syndrome but the presentation is atypical. In these cases, an intracompartmental pressure monitor can be used as an adjunct to other diagnostic tools.

  The mainstay of diagnosis is a high index of clinical suspicion particularly in high risk cases. However difficulty can be encountered in diagnosing compartment syndrome based on clinical picture alone, as the signs and symptoms can be ambiguous. Diagnosis is challenging, and can be missed despite clinical vigilance. […] The five Ps that have been described historically in relation to compartment syndrome pain, pulselessness, paresthesia, pallor, and paralysis are signs of ischemia and not compartment syndrome. However, the three main findings that point toward compartment syndrome which clinicians rely on are: 1) pain out of proportion to expectation, 2) stretch pain, ie, pain exacerbated by passive movement/stretch of the muscles, and 3) tense swelling. […] Though there are no reproducible and reliable tests for compartment syndrome, measurement of intracompartmental syndrome is required in cases where diagnosis is unclear.

  Acute compartment syndrome is a serious condition that involves increased pressure in a muscle compartment. It can lead to problems with blood flow to the affected area leading to muscle and nerve damage. […] To confirm the diagnosis, the provider may need to measure the pressure in the compartment. This is done using a needle placed into the affected body area. The needle is attached to a pressure meter. The test may be done at rest or during and after an activity that causes pain. […] With prompt diagnosis and treatment, the outlook is excellent and the muscles and nerves inside the compartment will recover. However, the overall outlook is determined by the injury that led to the syndrome. […] If the diagnosis is delayed, permanent nerve injury and loss of muscle function can result. This is more common when the injured person is unconscious or heavily sedated and cannot complain of pain. Permanent nerve injury can occur after less than 12 to 24 hours of compression.

  Compartment syndrome is a surgical emergency that can present after a variety of insults, ranging from those we commonly encounter in the ED (fractures, crush injuries) to more rare clinical presentations (snake bites, electrocution). […] The diagnosis of compartment syndrome relies heavily on clinical judgement, based on both the patients history and physical exam, followed by the diagnostic adjunct of measured compartment pressures. […] The normal pressure in a muscle compartment is less than 10 mmHg, and blood flow may start to be compromised at pressures greater than 20 mmHg. […] If the absolute pressure 30 mmHg in any patient, 20 mmHg in hypotensive patient, pressure is 20-30 mmHg, there has been interrupted arterial perfusion for 4 hours, and/or clinical signs are present, consultation of orthopedic surgery for emergent fasciotomy is recommended.
