Abstract • We treated two cases of severe envenomation by the scorpion Centruroides exilicauda. The first infant was treated with a species-specific scorpion antivenom, which produced a delayed but dramatic return of all vital signs to normal. A second infant was treated with two doses of intravenous propranolol hydrochloride and had a rapid, dramatic decrease in heart rate but only gradual resolution of neurologic symptoms. These cases demonstrate the severe symptoms of envenomation by this scorpion in the infant and show two possible treatments. (AJDC 1984;138:1136-1139) References 1.
