Management and Prognosis of Snake Envenomation Among Pediatric Patients: A National Database Study

Snakebites constitute a common medical emergency in tropical and subtropical regions. Pediatric snake envenomation is a special category that has not been well studied. This study investigated the management and prognostic factors of snake envenomation in children using a Taiwanese national database.

This observational study used the National Health Insurance database of all pediatric snake envenomation patients treated from 2005 to 2009. Patients' demographic data, antivenom types and doses, medical and surgical interventions, and prognostic variables were collected. Comparisons were made according to the envenomation types, age groups, and whether the patients were hospitalized using univariate and multivariate methods.

A total of 106 patients' data were collected. Of the patients, 73 (68.9%) were male, 62 (58.5%) were under the age of 12, 69 (65.1%) received intravenous (IV) antibiotic treatment, 38 (35.9%) were hospitalized, 5 (4.72%) required surgical intervention, and none died. Compared with non-hospitalized patients, the patients who required hospitalization were more likely to have suffered hemorrhagic envenomation ( p = 0.035), receive IV antibiotic treatment ( p = 0.0078), and require surgical intervention ( p = 0.005). In the multivariate analysis, hemorrhagic envenomation was an independent predictor for hospitalization (odds ratio: 3.47, 95% confidence interval: 1.18-10.21) after adjusting for other covariates. No significant differences were observed between age groups in total antivenom usage ( p = 0.2880), IV antibiotic usage ( p = 0.3190), hospitalization ( p = 0.3988), and surgical intervention ( p = 0.1874).

In this Taiwanese population-based national database study, antivenom treatment of pediatric snakebite patients resulted in zero mortality and a low surgical intervention rate. Patients with hemorrhagic envenomation were associated with a higher probability of hospitalization.
