The Neuroprotection of Sevoflurane Preconditioning on Intracranial Aneurysm Surgery

The Neuroprotection of Sevoflurane Preconditioning on Perioperative Ischemia-reperfusion Injury During Intracranial Aneurysm Surgery

The current study is designed to clarify the neuroprotective effect of sevoflurane preconditioning on the patients underwent intracranial aneurysm surgery.

The current study is designed to clarify the neuroprotective effect of sevoflurane preconditioning on the patients underwent intracranial aneurysm surgery. The patients with cerebral aneurysm will be recruited in current study. The sevoflurane preconditioning will be performed before the surgical procedure. The neurological injury biomarkers, such as S-100b and NSE will be detected. The neurological function and recovery will be assessed after the surgery.

Inclusion Criteria:

• Patient under intracranial aneurysm surgery.

Exclusion Criteria:

• Patients who refused to participate or who had a history of chemotherapy/convulsions two weeks prior to admission, stroke/cardiopulmonary resuscitation/head trauma three months prior to admission, Alzheimer's disease, amyotrophic lateral sclerosis, and prior melanoma were excluded.
