Case Reports
Cardiac tamponade complicating anaesthetic induction for repair of ascending aorta dissection.
A case is described of a 69-year-old woman with dissection of the ascending aorta who developed cardiac tamponade during induction of anaesthesia. The tamponade was diagnosed by a haemodynamic profile showing approximation of the central venous, pulmonary wedge and pulmonary arterial diastolic pressures, and was treated with rapid surgical intervention and drainage of the haemopericardium. Cardiac tamponade and dissecting aneurysms of the ascending aorta are conditions with contrasting anaesthetic considerations and the problems encountered are discussed.

Case ReportsArterial hypertension associated with the use of a tourniquet with either general or regional anaesthesia.
A hypertensive patient with left cardiac enlargement developed marked hypertension under general anaesthesia, during which time a tourniquet was applied around his thigh. When the tourniquet was released, severe hypotension ensued which responded to therapy. The patient, however, died 16 h later of a myocardial infarction. ⋯ A 30% increase in systolic and/or diastolic arterial blood pressure occurred in 27% of the total patient material and in 67% of those who had had a general anaesthetic. There was a higher frequency of the occurrence of "tourniquet hypertension" with older age, longer operations and the operation site being the lower rather than the upper limb. Tourniquet hypertension rarely occurred in patients with spinal anaesthesia (2.7%) and brachial plexus blockade (2.5%), while those with intravenous regional anesthesia had a higher incidence (19%) of hypertension.
