Abstract

We report the initial result of a series of clinical measurements of cerebral cortical oxygen tension in patients undergoing surgery for intracranial arterial aneurysms. This group of patients, the majority of whom present with sub-arachnoid haemorrhage (s.a.h.), frequently suffer from delayed cerebral artery vasospasm which may not manifest itself clinically, yet may seriously decrease blood flow and thus cortical oxygenation may become compromised. Once established, vasospasm is at present refractory to all forms of treatment, and unfortunately anaesthesia and surgery themselves may lead to further serious and irreversible vasospasm, and hence to neurological deficits, despite the advances in both operating and anaesthetic equipment and techniques of the last decade.
