Predictive Factors for Death After Snake Envenomation in Myanmar

摘要: Introduction Factors predictive for death from snake envenomation vary between studies, possibly due to variation in host genetic factors and venom composition. This study aimed evaluate Myanmar. Methods A prospective was performed among adult patients with snakebite admitted tertiary hospitals Yangon, Myanmar, May 2015 August 2016. Data including clinical variables laboratory parameters, management, outcomes were evaluated. Multivariate regression analysis at the time of presentation hospital. Results Of 246 recruited into study, 225 (92%) survived 21 (8%) died during hospitalization. The species responsible a bite identified 74 (30%) patients; majority bites Russell's vipers (63 patients, 85%). independent included 1) duration arrival hospital >1 h (odds ratio [OR]: 9.0, 95% confidence interval [CI]: 1.1–75.2; P =0.04); 2) white blood cell counts >20 ×10 3 cells·μL -1 (OR: 8.9, CI: 2.3–33.7; =0.001); 3) presence capillary leakage 3.7, 1.2–11.2; =0.02). delay antivenom administration >4 increases risk (11/21 deaths). Conclusions Patients who present these should be recognized provided early appropriate intervention reduce mortality rate adults
