General SCUBA Diving Topics
- 2 scientists refute online cures for jellyfish stings
- Recommended: "Sting No More" spray and cream; Vinegar; Hot water (>45C, >113F)
- Avoid: Sea water; Fresh water; Ice; Scraping (e.g. with a credit card)
- Source: "Cubozoan Sting-Site Seawater Rinse, Scraping, and Ice Can Increase Venom Load: Upending Current First Aid Recommendations," Toxins, March 15, 2017
- The Toxins article faulted WebMD and the Mayo Clinic's website for advising people to rinse jellyfish stings with seawater to "remove" or "deactivate" stingers, and for advising use of a credit card to scrape them off.
- Sting-relief research touts vinegar's effect - Honolulu Star-Advertiser - Jellyfish (including the Hawaiian Box Jellyfish and probably the Portuguese man-of-war)
- Box jellyfish are known to cause 100 deaths a year around the world.
- In Hawaii, box jellyfish are known to come into leeward and southern shores with the tide at night some eight to 10 days after a full moon.
= Do this ASAP
- Vinegar - Do this first. Douse affected skin area with vinegar.
- Hot water works well on jellyfish venom stings as it significantly reduces hemolysis, the destruction of red blood cells at the wound. UH advises running the hottest water you can stand for 20 or 30 minutes.
- Sting No More - a therapeutic ointment (containing vinegar and copper gluconate) and rinse developed by UH with the USA Department of Defense. (rinse solution spray and a treatment cream)
- NOT Recommended = Don't do this
- Cool or cold water
- Over-the-counter products were found to be ineffective. (Lidocaine, Ethanol, Isopropanol)
- Using an ID card and shaving cream. (Duh!)
- Scraping the skin will activate undischarged venom cells.
- Vinegar, heat are best way to treat man-of-war stings, UH study finds
- Packing tips for dive trips:
- Malaria medication
- Alcohol-based ear drops (should be used after every day of diving)
- Ointments for scratches
- A course of wide-spectrum antibiotics (just in case)
- Ear medication (for infection) (e.g. Garamycin Otic)
- Eye medication (for infection) (e.g. Sodium Sulamyd)
- Hep.A, Hep.B, Typhoid, Polio, Diptheria&Tetanus, TB, etc...
- Motion Sickness = Sea Sickness
- CDC = Centers for Disease Control and Prevention
- DAN = Divers Alert Network
- Exercise Before, During, and After Diving - Don't Do It !!!!
- IAMAT = International Association for Medical Assistance to Travellers
- Malaria Links
- Lariam (= Mefloquine = Mephaquine) Mefloquine should be considered strictly as a treatment drug, not a preventative. Neuro-toxicity. Side-effects may begin with diarrhea (not necessarily 'disabling'). The disabling 'unwanted effects' can be dizziness, lethargy, insomnia, 'pins-and-needles', severe headache or migraine, uncontrollable anxiety, unexplained depression, and sometimes developing further into symptoms as severe as a violent mood shift, fits and seizures, panic attacks, and serious psychosis ('detachment from reality'). These are the so-called neuro-psychiatric effects.The residual effects of mefloquine can last years. Mefloquine is not recommended for divers because: it may have adverse side-effects on the sense of balance; it may induce side-effects which could be mis-diagnosed as neurological decompression illness; it may adversely interact with the effects of raised partial pressure of nitrogen. Combined with other problems (allergies; epilepsy; kidney or liver or heart complaints; pregnancy) or other drugs (beta-blockers; any other anti-malarial drug; halofantrine), Mefloquine can be fatal.
- Doxycycline (= Vibramycin) May increase photosensitivity (susceptibility to sunburn).
- Chloroquine. Often combined with proguanil. (Aralene?)
- chloroquine phosphate
- 2020 CoViD-19 Pandemic: People died after self-medicating with this drug after President D.Trump recommended (in the 2020-03-20 White House briefing) two anti-malaria medications. Do not take these drugs for CoViD-19 (to prevent or to cure). They are not effective and can be deadly.
- Avoid being bitten (insects / bugs / mosquitos) ...
