What are the modifiable and non-modifiable risk factors for postoperative delirium in patients undergoing cardiac surgery?
Higher intraoperative sufentanil doses, along with non-modifiable factors like advanced age and longer bypass times, independently predict the development of postoperative delirium in cardiac surgery patients.
High sufentanil doses may increase delirium risk; leaves open whether dose reduction prevents postoperative delirium after cardiac surgery.

Sabol et al. (2015) conducted an observational in Postoperative delirium (n=250). Higher sufentanil dose vs. Lower sufentanil dose was evaluated on Development of postoperative delirium (OR 5.657, 95% CI 2.159-14.821, p=<0.001). Higher doses of sufentanil administered during anesthesia significantly increased the risk of early postoperative delirium (OR 5.657) in patients undergoing cardiac surgery.
