Why the study?
The implications of preanesthetic blood pressure values compared to baseline on postoperative in-hospital 30-day mortality remain underexplored.
Does a decrease in preanesthetic blood pressure compared to baseline increase 30-day postoperative mortality in adults undergoing non-cardiac surgery?
Population
60,534 adults scheduled for non-cardiac surgeries at a tertiary care center in Seoul, Korea
Comparison
Discrepancies between baseline ward blood pressure and blood pressure measured right before anesthesia
Follow-up
30 days

Preanesthetic BP drop ≥20 mmHg from baseline may flag higher 30-day mortality risk; leaves open whether deviation thresholds should inform perioperative decisions.
Does a decrease in preanesthetic blood pressure compared to baseline increase 30-day postoperative mortality in adults undergoing non-cardiac surgery?
A decrease in preanesthetic systolic or mean blood pressure of 20 mmHg or more from baseline significantly increases the risk of 30-day postoperative mortality in non-cardiac surgery patients.
