Abstract
A case of in-hospital thoracotomy with subsequent open chest cardiopulmonary resuscitation of a polytraumatized patient is reported. Emergency thoracotomies are rare interventions in challenging situations. Up to now there are only few standards or uniform education and training concepts. The indications are often a borderline decision. The aim of thoracotomy and open resuscitation in combination with a reduction in circulation, for example by cross-clamping the aorta, is to save time to address reversible causes of the hemorrhage, redirect the blood volume into the vital cerebral and coronary circulation and minimize bleeding from subdiaphragmatic bleeding sources. Ultimately, in case of doubt, the thoracotomy can be performed for the patient's benefit with the appropriate indications.
