Contralateral tension pneumothorax during thoracotomy for lung resection.

A patient underwent right thoracotomy and upper lobectomy for a mass found on routine chest radiography. He became profoundly cyanosed with a bradycardia and severe reduction in oxygen saturation at completion of surgery. The diagnosis of tension pneumothorax on the contralateral side to surgery was made and treatment instituted. The causes, treatment and implications of such an event during general anaesthesia for lung resection are discussed.
