Factors Affecting the Time to Postoperative Recovery of Consciousness in Patients Undergoing Cardiac Surgery With Cardiopulmonary Bypass: A Retrospective Study

Preoperative renal dysfunction and brain atrophy were identified as factors affecting the postoperative time to recovery of consciousness after cardiac surgery with cardiopulmonary bypass. Additionally, cardiopulmonary bypass time and hypoalbuminemia suggested that they were related to the time to recovery of consciousness. For patients with renal dysfunction, brain atrophy, or hypoalbuminemia, adjusting the dose and timing of anesthetic agent administration during induction and surgery may help reduce the time to recovery of consciousness.
