Abstract
Purpose
To identify the incidence and outcomes of postoperative delirium after cardiopulmonary bypass machine in adult cardiac surgery patients.
Method
A prospective observational study was conducted in a single-center institution in the Republic of China. This study included 273 patients who underwent cardiac surgical procedures requiring cardiopulmonary bypass machine utilization.
Results
This study used the Confusion Assessment Method to screen for delirium. Univariate analysis identified advanced age, emergency surgery and prolonged aortic cross-clamping time as significant predisposing factors for delirium, which occurred in 19.8% (n = 54) of cases and typically developed in average of 4.8 ± 3.28 days after the surgery. The analysis also identified that delirium was associated with increased complications and external referrals. A total of 142 patients (52.1%) were discharged to their homes, wherein the discharge rate in the delirium group was notably lower, with only 35.2% (n = 19) of patients, than in the delirium-free group with 56.2% (n = 123) of patients.
Conclusion
Considering the increased probability of delirium-related complications following cardiac surgery, it is important to develop effective preventive strategies for patients with perioperative risk factors, such as advanced age, emergency surgery and prolonged cross-clamp time, by implementing practical measures to minimize the risk of delirium.
