Utilization of whole body computed tomography in polytrauma patients.

Abstract

To determine the safety, feasibility, and utility of whole body computed tomography (WBCT) in polytrauma patients. A second objective was to describe the utilization of the VetMouse Trap for sedated WBCT in polytrauma patients. A prospective, observational study in a high-volume private practice. Any cat or dog weighing <20 kg that presented to the emergency department following a polytrauma was eligible. Patients were given analgesia and sedation prior to placement in the VetMouse Trap. A WBCT was then performed. A total of 16 patients (8 dogs and 8 cats) met inclusion criteria. All patients presented with blunt trauma; 3 also had evidence of penetrating wounds. Five (31.25%) patients met inclusion criteria for WBCT based on their neurological evaluation. Five (31.5%) were non-ambulatory with suspicion of orthopedic injury, and 37.5% met additional criteria for WBCT. The most common areas of injury were head (43.7%), lungs (25%), and pelvis (25%). Four patients (25%) had evidence of cavitary effusion that was not seen on focused assessment using sonography for trauma (FAST) scan. No patient had any adverse events during the CT. This study demonstrated successful WBCT imaging of the sedated small animal polytrauma patient with the VetMouse Trap.
