Thoracic trauma

The physiologic equilibrium of chest injury patients is frequently precarious, and mild stress during examination and treatment may precipitate acute decompensation and death. This is particularly true with the respiratory system, where the normally large respiratory reserve capacity may be rapidly lost. Accurate assessment of the nature of the thoracic injury and the severity of that injury must be determined in order to formulate a therapeutic plan. Many thoracic injuries, such as pneumothorax, pulmonary contusions, or rib fractures, will be self-limiting. Other conditions must be recognized for their potentially lethal nature and dealt with aggressively, and these include cardiac tamponade, tension pneumothorax, and esophageal perforation. By performing a systematic evaluation of the patient and confirming or denying the presence of all possible types of thoracic injury, the veterinarian may avoid overtreatment of self-limiting lesions and recognize and aggressively treat those with potentially fatal outcomes.
