| Abstract: | OBJECTIVES: Canine bite wounds may cause severe underlying tissue trauma even with no clinically evident puncture wounds. In order to assess the ability of pre-operative diagnostic parameters to predict the extent of internal damage inflicted by a thoracic bite wound, the clinical, radiological and surgical data of 45 dogs that sustained thoracic bite trauma were recorded. METHODS: Clinical, radiographic and surgical parameters from 45 dogs of various breeds with thoracic bite trauma, were analysed (P<0.05). All dogs were treated according to a previously described protocol and had exploratory surgery including a thoracotomy. RESULTS: Mainly small-breed dogs were traumatised. Clinical and radiological data were suggestive of internal trauma but not reliable as accurate indicators for internal lesions. Only radiological evidence of lung contusion was significantly associated with the presence of surgically confirmed lung contusion (P=0.006). Dogs with postoperative wound complications had a significantly higher risk of dying than those without complications (P=0.04). CLINICAL SIGNIFICANCE: This study concludes that according to protocol an optimal management of thoracic bite wounds in small dogs includes surgical exploration of the wound and the thoracic cavity in the presence of flail or pseudo-flail chest, fractured ribs, radiological evidence of lung contusion, pneumothorax or any combination of these. |
