Abstract:
A 60-year-old patient suffered a pulmonary embolism following the application of an Esmarch and pneumatic tourniquet before arthroscopy of the knee. The diagnosis was suspected because of sudden hypotension, ECG changes, a decrease in end-expiratory carbon dioxide concentration and oxygen desaturation as indicated by pulse oximetry. Before performing a sternotomy and cardiopulmonary bypass for removal of pulmonary artery clots, the diagnosis was confirmed by the demonstration of severe right ventricular strain using transoesophageal echocardiography.
