Venomous animals, Serpent Bites, Amazonian Ecosystem


Introduction: Snakebite accidents are a public health problem and are considered clinical emergencies, what makes studies in high-incidence regions very important.

Objective: To describe the clinical and epidemiological aspects of patients suffering from snakebite accidents in a region of the Western Amazon, Brazil.

Methods: It is a cross-sectional, retrospective and documentary quantitative approach, from 2015 to 2016, held at the Regional Hospital of Juruá, located in the city of Cruzeiro do Sul, Acre, Brazil. Epidemiological data were obtained from the forms of the Notification Disease Information System (SINAN), in the Epidemiological Surveillance Sector of the hospital. The following variables were verified: month of occurrence, snake identification (type of accident), accident location (urban and rural), locality, municipality, victim data (age group, sex, anatomical region affected), symptoms and signs circumstances of the accident, time elapsed between accident and care, number of ampoules used, and type of serum.

Results: An average of 124 cases of snakebite accidents were treated per year (76.71 cases per 100,000 inhabitants/year), most of them were botropic accidents and the patients were male adult and rural workers, bitten in the lower limbs. More than 30% of cases were treated six hours after poisoning and 24-hour care is a risk factor for complications, as seven of the eight patients who had complications were treated within one day of the accident.

Conclusion: It was presented a constant increase in the cases, which generated a worrying point of reflection, which may be associated with two factors, where one turns to the improvement in the displacement of victims (improvements in branch roads and implementation of SAMU speedboat) facilitating plus transport and telephone coverage by improving communication, or the failure of public health policies to provide better conditions and guidance to the population.
