RESUMO
Background: Snake bite envenomation remains one of the commonest causes of mortality and morbidity in rural West Bengal. Objective of present study was to compare the rationality, effectiveness and adherence to standard treatment guidelines of Government of West Bengal of snake bite management over the high-risk periods of two years.Methods: This was a comparative study of snake bite management between 2016 and 2018 (over April to September) during peak risk season in a tertiary care teaching hospital in rural Bengal. The data was collected retrospectively from the treatment records in 2016 and from patients admitted with history of snake bite in the Medicine ward, ICU and ITU in 2018.Results: Records from 2016 yielded 177 snake bite patients (144 venomous and 82.5% neurotoxic envenomation) and in 2018, 190 cases (114 venomous and 71.1% neurotoxic). There was delay in presentation (>2 hours) in almost 80% cases in both years and 2.56% had anaphylactic reaction following ASV administration in 2018 against 3.15% in 2016. Ventilator support was necessary for 12% patients in 2018. Overall percentage of mortality reduced from 6.70% to 3.2% in 2018. Adherence to snake bite management STG was seen in 81.8% of the retrospective records vis a vis 80% cases in prospective analysis (p = 0.21).Conclusions: The survival rate in venomous snake bite is found to be high in this institution over last two seasons of snake bite. The practice of snake bite management is found to be adherent with standard protocol in most cases.
RESUMO
Background: Rural Bengal has one of the highest snakebite prevalence in India. This prospective observational study was initiated with the motive to analyse the effects and adherence to implementation of the new national snakebite protocol 2016.Methods: Data were collected from the patients admitted with snake bite on a pre-designed and pre tested case study form and analysed with the help of descriptive statistics.Results: A total of 75 patients arrived in the hospital during the study period out which 53 were male (most in the age group of 31-40 years) and majority of them were farmers (26.6%) or housewives (25%). Maximum of them were bitten in the lower limbs (54.6%) and peak time of bite was between 6 am-12 pm (40%). Most of them reached the hospital late, i.e., beyond 2 hours (70.6%). It was found that there were 26 neurotoxic, 16 hemotoxic and 1 neuro-hemotoxic cases and the rest were non-venomous cases. Fifty-one of them received ASV and 4 died. There was 80% adherence in the indication of ASV administration, 73.3% in the ASV dose, 32% in the monitoring after ASV administration, 94.66% in the monitoring 20 WBCT, 100% in adherence to haemodialysis as indicated.Conclusions: The results showed good adherence in all the parameters. Protocol guided treatment has also resulted in rational use of ASV. So, from this study, it was concluded that protocol guided treatment is effective in snakebite management, but its continuous revision and amendments should be considered in future.
