Characterization and treatment protocol of injuries inflicted to humans by synurbic European wild boars (Sus scrofa).

ABSTRACT

PURPOSE: Wild boar (Sus scrofa) has spread and colonized urban areas. The closer contact with humans can lead to wild boar-inflicted injuries. The objectives of this study are 1) to systematically review the literature on wild boar-inflicted injuries; 2) to describe our wild boar-inflicted wound management protocol; and 3) to analyse the features, outcomes and complications of our case series. METHODS: First, a systematic search of the literature was performed using the PubMed (MEDLINE) electronic database. Then, our evidence-based wild boar-inflicted wound management protocol was described. Finally, a retrospective case series study including all the patients with wild boar-inflicted injuries attended in our Emergency Department (2020-2022) was analysed. RESULTS: Fourteen studies (twelve case reports and two case series) were selected for the literature review. Our case series included 34 patients 50.0% of them presented superficial wounds and 38.2% penetrating wounds. Most of the wounds occurred in the lower limbs (71.9%). Following our protocol, 30.0% of the wounds were primarily closed, the 70.0% of the patients received antibiotics (92.3% in penetrating injuries) and the 26.7% received an antitetanic vaccine. Only one patient (2.9%) presented a complication. CONCLUSIONS: This study reports the first specific wild boar inflicted-wound management protocol, which led to a low complication rate. Open wounds affecting the lower limbs were the most common lesions. Care should be taken with penetrating tusk injuries. Wide-spectrum antibiotic and antitetanic treatments are recommended. Decisions on wound management should be taken case-by-case, while antirabies vaccination depends on the local status of the disease.
