We conducted prospective, randomized analytical and observational trials to
assess reconstitution times of two lyophilized crotaline snake antivenoms,
Antivenin (Crotalidae) Polyvalent [Wyeth-Ayerst] (ACP) and affinity-purifi
ed, mixed monospecific crotalid antivenom ovine Fab (CroTAb(R)) (Fab antive
nom). The analytical experiment indicated Fab antivenom and ACP reached the
ir maximum protein concentration at 25 and 45 min, respectively. In the obs
ervational experiment, Fab antivenom (median 40 min) had a shorter reconsti
tution time than ACP (>90 min, p < 0.008). (C) 2000 Elsevier Science Ltd. A
