Key result
Intraoperative hypotension (mean blood pressure decrease >30% from baseline) was significantly associated with postoperative ischemic stroke, which occurred in 0.09% of the 48,241 surgical cohort.
Why the study?
Does intraoperative hypotension increase the risk of postoperative ischemic stroke in patients undergoing noncardiac and nonneurosurgical procedures?

Does intraoperative hypotension increase the risk of postoperative ischemic stroke in patients undergoing noncardiac and nonneurosurgical procedures?
Intraoperative hypotension, specifically a mean blood pressure decrease of >30% from baseline, is significantly associated with an increased risk of postoperative ischemic stroke in noncardiac, nonneurosurgical procedures.
Bijker et al. (2012) conducted a case-control in Patients undergoing noncardiac and nonneurosurgical procedures (n=294). Intraoperative hypotension vs. No intraoperative hypotension was evaluated on Occurrence of an ischemic stroke within 10 days after surgery. Intraoperative hypotension (mean blood pressure decrease >30% from baseline) was significantly associated with postoperative ischemic stroke, which occurred in 0.09% of the 48,241 surgical cohort.
