Surgical hazards posed by marine and freshwater animals in Florida.
Marine and freshwater animals can cause injury to humans by biting, stinging, being poisonous to eat, and causing infections. Biting aquatic animals in Florida include sharks, barracudas, alligators, and moray eels. Devitalized tissue should be débrided, and vascular, neurologic, and tendinous injuries should be repaired. Radiographs should be obtained to examine the injury sit for fractures and retained foreign bodies (teeth). The spines of stingrays and marine catfish can cause soft tissue injury and infection. The spine has a recurved, serrated shape that may cause further injury and break if it is pulled out. The venom may cause local tissue necrosis requiring débridement. Soft tissue infections with marine Vibrio bacteria can occur after eating raw oysters or receiving even minor injuries from marine animals. Thirty-one individuals developed soft tissue infections, 49 developed sepsis, and 23 developed both sepsis and soft tissue infection with marine Vibrio species during a 12-year period. Sixteen patients developed necrotizing soft tissue infections. Treatment is with antibiotics and débridement when necrosis occurs.
