Sedation of patients with acute aneurysmal subarachnoid haemorrhage with Ketamine is safe and might influence the occurrence of cerebral infarctions associated with delayed cerebral ischemia

Highlights - Ketamine use in sedated and ventilated patients with acute aneurysmal SAH is safe and reduced the intracranial pressure. - Ketamine use in sedated and ventilated patients with acute aneurysmal SAH lead to a significant reduction of vasopressors dosage. - The rate of cerebral infarctions associated with delayed cerebral ischemia was lower in the patient group who was treated with Ketamine. - Ketamine treatment of patients with acute aneurysmal SAH was not associated with a higher complication rate.
