Case Based for July
While bringing in toys from outside, an eight-year-old male was bitten by a juvenile Western Rattlesnake. He noticed immediate pain in his right third digit. EMS was activated and transported the patient 45 minutes to our facility in 45 minutes. EMS noted normal vital signs and discoloration to the digit. They also noted redness to the arm which was attributed to the blood pressure cuff. The patient was immediately evaluated, and an envenomation was diagnosed. He was immediately given the four units of crotalid antivenom in the pharmacy. The areas of redness were noted to ascend to the right axilla. The outer limits were marked and timed. Labs to included CBC, CMP, PT/INR, and PTT were sent and normal. The patient’s arm was elevated with pillows. The transfer process was initiated; however, the regional quaternary children’s hospital did not have antivenom in its formulary. Thus, a smaller hospital with pediatric capabilities was chosen. Air transport was unavailable due to significant thunderstorms in the area, and ground transport was also delayed. In the interim, the patient’s arm pain worsened, as did the erythema of the arm. Two additional doses of antivenom were acquired from a neighboring hospital and transported to our facility by EMS. Approximately five hours after arrival, the patient was transported to the receiving facility with the aircrew providing patient care and infusing the additional two vials of antivenom. The patient was admitted to the ICU, received six additional vials of antivenom, and recovered well. He was discharged home four days later with instructions for daily wound care. Each year, approximately 8,000 people are bitten by snakes in the United States. The overwhelming majority of these are from the crotalid family, which includes rattlesnakes, cottonmouths, and other pit vipers. Crotalid venom degrades structural proteins (like collagen and fibrin), which compromises…
