The trauma patient - critical decision making - when to explore the chest?

Abstract

The critical decisions regarding thoracotomy for trauma occur soon after the injury, when decisions have to be made that may influence survival or have an impact on morbidity if operation is delayed. Roadside thoracotomy is impractical, and should not be considered; instead, patients should be taken rapidly to the nearest hospital. Endotracheal intubation prior to transport appears to be beneficial, but the application of MAST trousers and the infusion of large volumes of fluid for hypovolaemia before control of haemorrhage offers no advantage and may be hazardous. On the whole, resuscitative thoracotomy is associated with a low salvage rate, especially for the patient sustaining blunt trauma, but may be worthwhile in the patient with penetrating trauma. Urgent, as opposed to immediate thoracotomy, should be undertaken once the patient has been stabilized. This may occur in most patients with penetrating injuries of the heart who survive to reach hospital, those with continuing, significant haemorrhage through chest drains, and those with tracheal, oesophageal and diaphragmatic injuries. Extensive open chest wounds require considerable ingenuity in closure, often with plastic surgical help. Patients with blunt traumatic rupture of the aorta often have multiple injuries, which may also be life threatening. If bleeding into the abdomen is demonstrated, then laparotomy should precede thoracotomy: musculoskeletal injuries and neurological injuries can usually be dealt with after the aortic rupture has been repaired.
