Multicenter Study Clinical Trial[Peroperative risks in cerebral aneurysm surgery].
The perioperative complications associated with cerebral aneurysm surgery require a specific anaesthetic management. Four major perioperative accidents are discussed in this review. The anaesthetic and surgical management in case of rebleeding subsequent to the re-rupture of the aneurysm is mainly prophylactic. ⋯ Its treatment is aggressive, with intravenous agents, mannitol, deep hypocapnia and/or lumbar drainage. Prophylaxis, according to the "brain homeostasis concept", is the preferred method to avoid these four peroperative accidents. It includes normal blood volume, normoglycaemia, moderate hypocapnia, normotension, soft manipulation of the brain and optimal brain relaxation.

Multicenter Study[Anesthesia and intensive care of subarachnoid hemorrhage. A survey on practice in 32 centres].
To assess the current practices in anaesthesia and intensive care in patients experiencing subarachnoid haemorrhage (SAH). ⋯ Twenty-nine French and three non French centers answered the questionnaire. In 14 centers, more than 60 SAH had been treated in the previous year. Angiography was performed under sedation with a benzodiazepine associated with an opioid (54%). Criteria for choosing an endovascular approach were the site of the aneurysm (81%), its neck size (42%) and the underlying disease (42%). Anaesthesia was induced with either propofol (60%) or thiopentone (40%) associated with an opioid and a muscle relaxant. It was maintained with either isoflurane (59%) or propofol (41%). Nitrous oxide was often associated (62%). During anaesthesia, nimodipine (84%), mannitol (69%), anticonvulsants (47%), dopamine (31%) and lidocaine (9%) were also administered. Postoperatively, nimodipine was administered for prophylaxis of vasospasm (97%) and transcranial Doppler was employed to diagnose vasospasm (50%). Other techniques of care included hypervolaemia (89%), controlled arterial hypertension (36%) and haemodilution (36%).
