• #1 Cochrane Corner: how effective are interventions for reducing symptoms and signs resulting from jellyfish stings?

  https://firstaidjournal.org/article/id/2540/

  This Cochrane Corner is based on a review that investigates the benefits and harms associated with interventions aimed at treating jellyfish stings in both adults and children. […] Many treatments have been suggested for the symptoms and signs of jellyfish stings, in order to deactivate the attached nematocysts, neutralize the venom, and provide symptomatic relief (including pain relief) and supportive care. […] Currently, for the treatment of jellyfish stings, the Australian Resuscitation Council and Red Cross recommend (1) the use of vinegar in tropical Australia or a cold/ice pack if vinegar is unavailable, and (2) hot water for stings in non-tropical regions or for obvious bluebottle stings. However, the effectiveness of different treatments is still unclear. […] Due to the very low certainty of the evidence, the effectiveness of any of the treatments identified by and evaluated in this review remains uncertain.

  https://www.hawaii.edu/news/2016/04/14/heat-trumps-cold-in-the-treatment-of-jellyfish-stings/

  A recent study by researchers at the University of Hawaii at Mnoa, published this month in the journal Toxins, may finally put to rest the ongoing debate about whether to use cold or heat to treat jellyfish stings. Their systematic and critical review provides overwhelming evidence that clinical outcomes from all kinds of jellyfish stings are improved following treatment with hot packs or hot-water immersion. […] People think ice will help because jelly stings burn and ice is cold, said Christie Wilcox, a postdoctoral fellow at the John A. Burns School of Medicine and lead author of the paper. […] But research to date has shown that all marine venoms are highly heat sensitive, thus hot water or hot packs should be more effective than cold packs or ice. […] The overwhelming preponderance of evidence supported the use of hot-water immersion (about 45 degrees Celsius). This is consistent with findings in more than a dozen articles, demonstrating that venom components are inactivated at temperatures between 40 and 50 degrees Celsius. […] Hot-water immersion is already the standard of care for other severe marine envenomations including potentially life-threatening stonefish stings, so these results help streamline the first-aid response. Its simple, really: if youre stung, use hot water or hot packs rather than ice or cold packs.

  https://www.peoplespharmacy.com/articles/how-to-ease-the-pain-of-a-jellyfish-sting

  The best remedies for a jellyfish sting may depend on the species of jellyfish. Vinegar is sometimes helpful, and so is hot water. […] There are many home remedies for a jellyfish sting, but medical authorities are skeptical about most of them. […] Aussie researchers have found that vinegar is not a good option for box jellyfish. […] The Australian scientists found that vinegar increased the amount of venom released by box jellyfish, Chironex fleckeri. […] Vinegar is also contraindicated for stinging sea anemone, as is ammonia. […] It seems that vinegar is helpful for the stings of some jellyfish species and harmful for those of others. […] Consequently, swimmers shouldn’t use vinegar on jellyfish stings unless they know precisely which species has caused the sting and whether vinegar will be helpful.

• #1 Jellyfish Stings and Their Management: A Review

  https://pmc.ncbi.nlm.nih.gov/articles/PMC3640396/

  Jellyfish (cnidarians) have a worldwide distribution. Despite most being harmless, some species may cause local and also systemic reactions. Treatment of jellyfish envenomation is directed at: alleviating the local effects of venom, preventing further nematocyst discharges and controlling systemic reactions, including shock. In severe cases, the most important step is stabilizing and maintaining vital functions. With some differences between species, there seems to be evidence and consensus on oral/topical analgesics, hot water and ice packs as effective painkillers and on 30 s application of domestic vinegar (4%6% acetic acid) to prevent further discharge of unfired nematocysts remaining on the skin. Conversely, alcohol, methylated spirits and fresh water should be carefully avoided, since they could massively discharge nematocysts; pressure immobilization bandaging should also be avoided, as laboratory studies show that it stimulates additional venom discharge from nematocysts. Most treatment approaches are presently founded on relatively weak evidence; therefore, further research (especially randomized clinical trials) is strongly recommended. Dissemination of appropriate treatment modalities should be deployed to better inform and educate those at risk. Adequate signage should be placed at beaches to notify tourists of the jellyfish risk. Swimmers in risky areas should wear protective equipment.

  These products can now help families, lifeguards, and EMS personnel effectively treat jellyfish stings in addition to more traditional household vinegar rinse followed by hot water immersion and topical antihistamine and glucorticoid creams. […] These jellyfish sting recommendations decrease venom load in the tissues with the following threefold approach: 1) Deactivate nematocysts preventing further envenomation: use vinegar (acetic acid 5%) or Sting No More as the initial 30 second rinse. 2) Decontaminate skin by plucking tentacles from skin with tweezers or gloved hand (do not scrape, shave or rub as pressure and manipulation triggers nematocyst release). 3) Denature injected venom in tissues: immerse the affected skin in hot water (45 C/113 F), hot shower to tolerance or heat pack application for 45 minutes. […] The aim now is to help educate others with these up-to-date recommendations.

  A new study of the man o war jellyfish found popular remedies like lemon juice and shaving foam make stings worse. Vinegar followed by heat is most effective. […] Scientists have found that applying vinegar is the best solution, and that popular remedies including urine, lemon juice, and shaving foam could make the situation worse. […] A recent study in Toxins, which investigated the efficacy of various remedies for stings from the Portuguese man o war (Physalia physalis) concludes that rinsing with vinegar before applying heat is the most effective treatment. […] The commonly recommended treatment of seawater and ice was found to cause more harm than good. […] We are absolutely 100% certain that vinegar does the trick. […] However, applying vinegar was shown to prevent further venom release, allowing the tentacles to be safely removed.

  Here’s some timely advice from a Californian dermatologist for anyone planning to swim in jellyfish territory. If you get stung, remove any clinging tentacles with your fingers or by scraping the skin with a credit card. Forget weird remedies such as hot sand, kerosene, or urine, and don’t douse the sting with fresh water—it forces toxins further into the skin. Dilute vinegar is good first aid for box jellyfish and Portuguese man-of-war stings, and ice is best for the rest.

  Jellyfish stings are common in coastal regions around the world. Understanding the benefits and harms of different treatments will help to know how best to treat the effects of a jellyfish sting. […] We found nine studies with 574 participants, assessing three groups of treatments. […] Due to our limited confidence in the available evidence, we cannot tell whether applying heat or cold to a jellyfish sting reduces or stops pain within one hour of treatment; reduces the need for retreatment or switching to the alternative treatment; reduces skin reactions in the first 24 hours (itchiness, red marks, or rashes); or causes any harms (burns or temporary redness around the area of application). […] Due to our low confidence in the available evidence, we cannot tell whether applying any of these treatments to a jellyfish sting reduces or stops pain within six hours of treatment, or causes harm.

  Hot water is often recommended. It should be hot enough to be painful but not so hot that it will burn the skin (110 to 113 F). […] Researchers tested first aid protocols and discovered that rinsing the site with undiluted vinegar (5 percent acetic acid) was helpful. […] Hot water, on the other hand, helps relieve the pain because heat inactivates key venom compounds. […] Both the American Red Cross and the American Heart Association suggest that certain jellyfish stings should be washed with vinegar for at least 30 seconds. This inactivates the venom of Olindias sambaquiensis and Physalia physalis (Portuguese man-of-war) species.

  Although the evidence was very uncertain, the data from the included studies did not refute the treatment recommendations of the 2010 Australian Red Cross guidelines (applying heat to non-box jellyfish stings in non-tropical Australia and applying vinegar to box jellyfish) and the 2000 International Life Saving Federation guidelines (applying vinegar to box jellyfish). […] Future research is needed to determine which treatments are most effective for treating signs and symptoms of jellyfish stings of a certain species. […] The only treatment to neutralize the venom is Australian anti-Chironex fleckeri serum. […] The most frequent jellyfish in Southern Brazil mainly cause localized pain and skin plaques. […] As highlighted in the Cochrane Review a vast majority of envenomation has extremely favorable outcomes and can be controlled by iced marine water compresses and a popular use of vinegar baths.
