Bothropic accidents directly impact health costs and the morbidity and mortality of the population. The objective of this research is to outline the clinical profile of cases attended by CIATOX-PR. This is an observational, retrospective, and cross-sectional study, conducted through the review of 1738 medical records created between 2014 and 2021. Epidemiological data of the patient (sex, age, origin, etc.), the accident (bite location, accident city, etc.), the clinical presentation (signs and symptoms), the treatment (time to antivenom administration, adverse events, etc.), and the evolution of the condition with and without specific antivenom therapy were collected. For statistical analysis, chi-square tests, McNemar's test, t-tests, ANOVA, or their parametric versions were performed. The observed results showed that, in most cases, the clinical profile of the accidents consisted of male individuals (77.33%), with an average age of 39.14 years (the youngest patient being 1 year old and the oldest being 88 years old) and with a mild clinical presentation. On average, the antivenom was administered in 4.49 hours. The most prevalent manifestations were local pain and edema. Edema proved to be an adequate parameter to assess the severity of the case, unlike laboratory tests, which did not demonstrate the ability to predict case staging. The main complications after the bite were acute renal failure, cardiorespiratory arrest, and amputations. In this scenario, it was observed that diagnostic errors, imprudence, lack of skill, lack of antivenom, and communication errors can delay the administration of the specific antivenom and lead to unfavorable outcomes for the patient. Therefore, it is essential to include this topic during the training of healthcare professionals, as well as to promote awareness of poisoning centers and collaborate with them.
