Introduction: bite affects about 2 million people every year, with more than 100000 mortalities annually. A person bitten by a snake represents a variety of symptoms. Snake bite might be asymptomatic or with mild local symptoms or even could lead to tissue damage and rapid death. This study aimed to investigate characteristics of snake bite in Northwest Iran. Methods: In this retrospective study, medical records of all patients with final diagnosis of snake bite who were admitted to Sina Clinical-Educational Center, the referral center for envenomation in Northwest Iran were investigated from 2002 to 2012. Demographic information and laboratory findings were collected using a checklist. Results: During a 10 year period, 160 individuals with snake bite were admitted, of which 128 (77.6%) were male. With regard to occupation, farmers accounted for the largest portion (n = 57, 34.6%). The most prevalent sites bitten by snakes were right hand (25.5%) and left leg (24.8%). Fifty-seven patients (34.5%) had leukocytosis and four (2.4%) had coagulopathy. Pain and swelling were two main complaints, with vomiting, dizziness, and tingling in extremities coming afterwards. Conclusion: Because snake bite is one of the most important emergencies presenting to emergency department and Iran’s geographic status bears wide spectrum of poisonous snakes, this study was performed to further explore the clinical and epidemiologic details of snake bite.
