[Anesthesia in Early Surgery and Endovascular Therapy for Aneurysmic Subarachnoid Hemorrhage]

Early surgery after SAH is frequently performed. The most important problems for anesthesiologists are the risk of rebleeding, the alteration of autoregulation and CO2 responsiveness, cardiac, respiratory and electrolytic alterations. In this phase the brain may be ischemic-edematous or haemorrhagic-compressive and the choice of anesthetic agent is made on the basis of cerebral conditions. The main goal is to control ICP and maintain adequate CPP. The endovascular treatment with Guglielmi detachable coils is usually performed in patients with poor neurologic and/or medical conditions. General anaesthesia under aggressive monitoring is advisable to control systemic pressure and to avoid movements.
