Q
4 yo boy is seen after rattlesnake bite to his hand. He is nauseated and vomits once. HR is 104, BP 95/59. He is alert but has progressive swelling around his hand and fingers. He receives an initial loading dose of CroFab (ovine) and is admitted. The BEST next step in management is:
A) administer Maintainence antivenom
B) observe and elevate the hand
C) obtain CBC, coags, renal function testing
D) perform pressure immobilization
A
A. For crofab (ovine antivenom), Maintainence dosing needed as opposed to anavip (equine) which has a longer half life and does not necessarily need maintenance dosing.
D is specifically NOT recommended for crotalidae bites. C is true but should have already been done.
