Effect of Ciprofol on Postoperative Cognitive Function in Patients Undergoing Cardiac Surgery with Cardiopulmonary Bypass: A Prospective, Randomized, Controlled Trial
Bibliographic record
Abstract
Purpose: To investigate the effects of ciprofol on postoperative cognitive function in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Patients and Methods: A total of 138 patients who underwent cardiac surgery with cardiopulmonary bypass were included in this prospective, randomized, controlled study. Patients were randomized into two groups: the Ciprofol group (Group C) and the Propofol group (Group P). During anesthesia induction and maintenance, the patients in Group C received ciprofol, whereas those in Group P received propofol. The primary outcome measure was the incidence of postoperative delirium (POD), which was assessed twice daily for 7 days after surgery via either the Confusion Assessment Method (CAM) or the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Statistical analyses included chi-square tests for categorical outcomes and relative risk calculations for POD. Additionally, delirium subtypes were recorded. The incidence of postoperative cognitive dysfunction (POCD) was evaluated at 1 and 3 months after surgery using the Telephone Montreal Cognitive Assessment (T-MoCA). Furthermore, the occurrence of postinduction adverse events, including hypotension, bradycardia, and tachycardia, as well as the incidence of postoperative complications, were also documented. Results: POD occurred in 19/64 (29.69%) patients in the Ciprofol group and 34/65 (52.31%) patients in the Propofol group (RR = 0.57; 95% confidence interval = 0.37 to 0.88; p = 0.009). There was no significant difference in the incidence of POCD at 1 month (22.03% vs 26.62%, p = 0.547) or 3 months (16.25% vs 16.00%; p = 0.771) after surgery between the two groups. Conclusion: Ciprofol was found to decrease the incidence of POD in patients who underwent cardiac surgery with cardiopulmonary bypass. Nevertheless, no significant effect of this intervention on the incidence of POCD was demonstrated at either 1 or 3 months after surgery. A reduction in the incidence of delirium may be associated with improved postoperative recovery, shortened hospital stays, and a decrease in long-term cognitive impairments. Registration: The study had been registered in the Chinese Clinical Trials Registry ( www.chictr.org.cn ; Trial Identifier: ChiCTR2200061712). Keywords: ciprofol, cardiopulmonary bypass, cardiac surgery, delirium, cognitive function

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
