sea anemone sting

Contact with the nematocysts or stinging cells of certain species of the flower-like marine coelenterates causing severe dermatitis with chronic ulceration. In some cases, signs and symptoms of a systemic reaction develop, including headache, nausea, vomiting, sneezing, chills, fever, paralysis, delirium, seizures, anaphylaxis, cardiac arrhythmias, heart failure, pulmonary edema, and collapse. In rare cases, it is fatal.


When systemic changes are present, vigorous therapy is indicated for hypotension. Diazepam is administered for convulsions. An electrocardiogram should be monitored for arrhythmias. Treatment for mild stings is symptomatic; application of vinegar to the sting area may inactivate the irritating secretion. All victims should be observed for 6 to 8 hr after initial therapy for rebound phenomenon.
