Why the study?
Intraoperative hypotension is a modifiable risk factor targeted to improve neurological outcomes despite lacking a known threshold value.
Highlights the importance of targeted blood pressure management using rScO2 or cerebral pressure autoregulation to mitigate the risk of intraoperative hypotension on neurological outcomes.
Supports cerebral autoregulation-guided BP targets in anesthesia; leaves open confirmation via prospective RCTs.
Despite the lack of a known threshold value, IOH is a modifiable risk factor targeted to improve neurological outcomes. Ideal BP management is recommended in order to maintain target BP based on the monitoring of rScO2 or cerebral pressure autoregulation.
