Periprocedural management of patients with subarachnoid hemorrhage

Anesthesiologists and intensivists may be involved in the management of aneurysmal subarachnoid hemorrhage (aSAH) patients at various stages of care. This article will review the recent advances in the periprocedural management of aSAH patients.

New scoring systems to assess gravity and prognosis of aSAH patients have been evaluated and proposed. Rebleeding still remains, with early aneurysmal treatment, a major challenge in the first hours of aSAH management. In the last decades, the treatment of the aSAH has shifted from clipping to coiling and more recently, the use of flow diversion technique has been introduced in selected patients. Although these improvements allow treatment of more complex aneurysms, they have implications for the anesthesiologist, including requiring the management of anticoagulation with its inherent risks. Even though knowledge, monitoring, and management of postprocedural phase of aSAH patients has improved, vasospasm and cerebral-delayed ischemia still remain the major and devastating complications in the postoperative course of aSAH patients.

Despite recent progress in the scoring, diagnosis, and treatment of aSAH patients, the periprocedural management of these patients is still a major challenge for anesthesiologists and intensivists, who are involved from the first phase of the aneurysm rupture through the postoperative phases and vasospasm period.
