AB The  venom  of  poisonous  snakes  and  lizards  may  be  predominantly  neurotoxic  (coral  snake)  or  predominantly  cytolytic  (rattlesnakes,  other  pit  vipers).  Neurotoxins  cause  respiratory  paralysis;  cytolytic  venoms  cause  tissue  destruction  by  digestion  and  hemorrhage  due  to  hemolysis  and  destruction  of  the  endothelial  lining  of  the  blood  vessels.  The  manifestations  of  rattlesnake  envenomation  are  mostly  local  pain,  redness,  swelling,  and  extravasation  of  blood.  Perioral  tingling,  metallic  taste,  nausea  and  vomiting,  hypotension,  and  coagulopathy  may  also  occur.  Thrombocytopenia  can  persist  for  several  days  after  a  rattlesnake  bite.  Neurotoxic  envenomation  may  cause  ptosis,  dysphagia,  diplopia,  and  respiratory  arrest.
