Abstract: | One hundred dogs with skeletal injury were evaluated for co-existing thoracic abnormalities. Parameters used to assess thoracic trauma were physical examination, thoracic radiographs, electrocardiograms and arterial blood gas PaO2. Thoracic abnormalities were found in 57 per cent of the dogs. Within this group, 77 per cent had abnormal thoracic radiographs, 44 per cent had abnormal low PaO2, and 30 per cent had cardiac arrhythmias. No clinical signs suggestive of thoracic injury were found on physical examination in 79 per cent of the dogs with thoracic lesions. |
