The Effects of Preoperative Resting Blood Pressure and Nighttime Blood Pressure on the Associations between Perioperative Blood Pressures and Postoperative Complications: A Prospective, Observational Study in Vascular Surgery Patients
Authors' conclusion
Intraoperative and postoperative hypotension were significantly associated with postoperative complications in vascular surgery patients. There were no statistically significant interactions between these associations and preoperative nighttime blood pressure, or ambulatory resting blood pressure.
Study context
- Population
- Patients undergoing vascular surgery under GA
- Participants
- 200 patients
- Outcome
- Comprehensive Complication Index at 30 days per minute with MAP < 65 mmHg
- Follow-up
- 30 days
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Increase in Comprehensive Complication Index per minute with mean arterial pressure (MAP) < 65 mmHg during anesthesia
0.15
Increase in Comprehensive Complication Index per minute with MAP < 65 mmHg in the PACU
0.09
Observational data: associations, not effects.
Further findings
Effect modification by preoperative resting and nighttime BP
- Preoperative resting and nighttime BP did not significantly modify the associations between intra- or postoperative hypotension and postoperative complications
