Principles of neuroanesthesia in aneurysmal subarachnoid hemorrhage: The Helsinki experience.

BACKGROUND

Aneurysmal subarachnoid hemorrhage is a devastating disease that is followed by a marked stress response affecting other organs besides the brain. The aim in the management of patients with aSAH is not only to prevent rebleedings by treating the aneurysm by either microneurosurgery or endovascular surgery, but also to evacuate acute space-occupying hematomas and to treat hydrocephalus.

METHODS

This review is based on the experience of the authors in the management of more than 7500 patients with aSAH treated in the Department of Neurosurgery at Helsinki University Central Hospital, Finland.

RESULTS

The role of the neuroanesthesiologist together with the neurosurgeon may begin in the emergency department to assess and stabilize the general medical and neurologic status of the patients. Early preoperative management of patients in the NICU, prevention of rebleeding, and providing a slack brain during microneurosurgical procedures are further steps. Postoperative management, prevention, and treatment of possible medical complications and cerebrovascular spasm are as necessary as high-quality microsurgery.

CONCLUSION

Multidisciplinary and professional teamwork is essential in the management of patients with cerebral aneurysms.
