ABSTRACT
Background: Snakebites remain a source of considerable morbidity and mortality in many countries with an estimated global true incidence of envenomation exceeding five million per year; with about 100 000 of these cases developing severe sequelae. Despite the availability of polyvalent snake antivenom; inappropriate first aid; the regional effects of envenomation; and inappropriate use of antivenom result in significant and at times potentially avoidable; morbidity and mortality - particularly in children. The study was undertaken in Ellisras (now Lephalale) hospital; Limpopo province due to the frequency of snake bites managed at the hospital. Methods: This was a record-based retrospective study in which patient files with the diagnosis of snake bite were reviewed. The objective of this study was to document the management of snakebites at Ellisras (now Lephalale) hospital; Limpopo; a rural hospital in South Africa. The hospital files of all patients managed at the hospital for snakebites from 1 January 1998 to 31 December 2001 were reviewed. Results: Seventy patients were treated for snakebites during the study period. The results showed a male preponderance (60) and a mean age of 27.3 years among the reported cases managed for snakebites. Twenty-nine patients (41.1) were bitten between dusk and dawn (18h00 and 06h00); 43 (61.4) were bitten on the lower limb and the mean duration of admission in the wards was 4.2 days. Twenty-one bites (30) were attributed to known poisonous snakes; 22 (31.4) received polyvalent antivenom; 42 (60) received promethazine which has not been shown to prevent anaphylactic reactions; 12 (17.1) developed complications; and 2 died (case fatality rate of 2.9). Conclusion: The findings of this study highlight gaps in the management of snake bites at this rural hospital where they occur frequently. It is crucial for primary care physicians to be familiar with the most common venomous snakes in South Africa and the management of their bites in humans. The importance of administering prophylactic antibiotic; tetanus toxoid in all confirmed snakebites; and close monitoring of all patients during and after antivenom administration form the basis of most clinical protocols on the management of snakebites

The purpose of this report is to describe a case of seve re snake bite with enve n o m ation by an A f rican puff adder(Bitis arietans). Presenting symptoms warranted administration of antivenon upon admission. The patient's ge n e ral condition improved. However bite-related trauma caused extensive phlyctenuar edema of the lower extremity with a high risk of compartimental syndrome due to hardening and compression. Due to the high risk for postoperative infection at our facility; apon ev ro t o my to relief pressure was not undert a ken immediately. Instead management consisted in close surveillance with rep e ated measurement of peripheral pulses by Doppler ultrasound and of intracompartimental pressure. The outcome was favo rabl e without need for aponevro t o my. This case demonstrates the value of intra c o m p a rtimental pressure measurement in cases invo lving this type of envenomation in function of available technical facilities

En 12 mois; 53 cas de morsures de serpents ont ete colliges. Le sexe masculin est le plus touche. Le tableau clinique est celui d'un syndrome inflammatoire localise au niveau des membres inferieurs; il est plus sensible a l'heparinate de sodium intraveineux qu'aux anti-flammatoires non steroidiens. La duree moyenne d'hospitalisation a ete de 2;87 jours. Le traitement a ete uniquement symptomatique et l'evolution favorable dans 100 pour cent des cas

Les morsures de serpents constituent par leur frequence l'une des principales urgences observees dans les dispensaires de brousse et l'une des grandes causes d'evacuation vers les centres de soins intensifs. Les soins sur place doivent se limiter au strict necessaire. L'important est d'assurer; dans les meilleures conditions; le transfert de la victime sur un centre correctement equipe. Sans minimiser la valeur du traitement symptomatique; il parait essentiel de rappeler que la serotherapie reste le traitement specifique de choix; dont l'efficacite est indiscutable tant au plan du pronostic vital que fonctionnel
