Why the study?
To describe associations between perioperative blood pressures and clinical postoperative outcomes, and investigate whether these associations depend on preoperative resting and nadir nighttime blood pressures.
Does intraoperative and postoperative hypotension increase postoperative complications in vascular surgery patients?
Does intraoperative and postoperative hypotension increase postoperative complications in vascular surgery patients?
Intraoperative and postoperative hypotension are significantly associated with increased postoperative complications in vascular surgery patients, and this risk is not modified by the patient's baseline resting or nighttime blood pressure.
May support minimizing perioperative time with MAP <65 mmHg in vascular surgery; hypothesis-generating and requires RCTs before practice change.
