Intraoperative Hypotension and Postoperative Newly Developed Cerebral Infarction in Patients With Aneurysmal Subarachnoid Hemorrhage: A Retrospective Cohort Study.

ABSTRACT:

Aims

To investigate the association between intraoperative hypotension and newly developed cerebral infarction in patients with aneurysmal subarachnoid hemorrhage (aSAH) undergoing aneurysm clipping or coiling.

Methods

The patients who had emergent clipping/coiling procedures for aSAH under general anesthesia were included. The major exposure was mean arterial pressure (MAP) below different absolute or relative thresholds characterized by area under curve (AUC), duration, and time-weighted average (TWA) value. The outcome was newly developed cerebral infarction. The associations between MAP and newly developed cerebral infarction were adjusted by other risk factors. Odds ratio and 95% confidence interval were used to present the statistical difference.
