Keywords:
Snake bite, envenomation, polyvalent antisnake venom, NigeriaAbstract
Objective: Antisnake venom (ASV) is a specific antidote for the management of snake bite envenomations. This study profiled the treatment and outcome of adult snake bite victims managed using low dose antisnake venom.
Methods: This was a 5-year retrospective study that involved all adult patients who presented in University of Benin Teaching Hospital, Benin City, Nigeria, with a history of snake bite. Information obtained were demographic characteristics, clinical features, and administered treatment per established. All patients with a diagnosis of snake bite envenomation were administered ASV.
Results: Sixty patients were seen during the study period, 35(58.3%) males, 25(41.7%) females with a mean age was 34.7±13.3. The mean time from bite to presentation was 14.67±14.05 hours with range of 148 hours. Twenty patients (33.3%) had snake bite envenomations, of these eleven (57.9%) were managed and discharged after administration of 30 to 40 mls of polyvalent ASV. The mean dose of PASV used was 3.9 ± 2.0 vials. The most encountered clinical indication for ASV administration was progressive painful swelling. No death was recorded throughout this period studied.
Conclusion: Adoption of the low dose regimen in the management of snake bite envenomations may be as effective as the traditional high dose regimen.
