Methods: We conducted a retrospective cohort study by reviewing medical records of patients with crotaline snakebite between 1991 and 2005. We used a structured questionnaire to abstract information on demographic variables, treatment, adverse effects of antivenom, and local/ systemic complications. T-test, chi-squared test, and multiple logistic regression were employed in data analyses.
