About this study
Official title: Effect of Perioperative Dezocine Administration on Postoperative Delirium in Elderly Patients Undergoing Cardiopulmonary Bypass Cardiac Surgery: A Randomized Controlled Trial
Postoperative delirium (POD) is a common complication in elderly patients undergoing cardiac surgery and is associated with prolonged hospitalization, increased morbidity, and poor recovery. Currently, effective pharmacological strategies for preventing POD remain limited.
This study aims to evaluate whether perioperative administration of dezocine can reduce the incidence of postoperative delirium in elderly patients undergoing cardiopulmonary bypass cardiac surgery.

This is a prospective, randomized, controlled clinical trial conducted at Fuwai Hospital. Eligible patients aged 65 years or older undergoing elective cardiopulmonary bypass cardiac surgery will be randomly assigned to receive either dezocine or normal saline control in a 1:1 ratio. Patients in the dezocine group will receive intravenous dezocine (0.1 mg/kg) before anesthesia induction and again before transfer out of the operating room. At each administration time point, dezocine will be diluted with normal saline to a total volume of 6 mL and infused intravenously over 3 minutes. Patients in the control group will receive equivalent volumes of normal saline at the corresponding time points.
The primary outcome is the incidence of postoperative delirium within 7 days after surgery. Secondary outcomes include delirium characteristics, postoperative recovery outcomes, pain scores, opioid consumption, sedation status, and perioperative complications.
This study will investigate the potential role of dezocine as a preventive strategy for postoperative delirium in high-risk elderly cardiac surgery patients.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DezocineDrug
Dezocine will be administered intravenously at a dose of 0.1 mg/kg before anesthesia induction and before transfer out of the operating room. At each administration time point, dezocine will be diluted with 0.9% normal saline to a total volume of 6 mL and infused over 3 minutes.
Normal Saline (NS)Drug
An equivalent volume of 0.9% normal saline will be administered intravenously at the same time points as the dezocine group, with the same infusion volume and administration procedure.
| Study group | Role | What they receive |
|---|---|---|
| Dezocine Group | Experimental | Not described Receives: Drug: Dezocine |
| Normal Saline Control Group | Active comparator | Not described Receives: Drug: Normal Saline (NS) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of postoperative delirium within 7 days after surgery
Measured: Within 7 days after surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Postoperative delirium (POD) is a common complication in elderly patients undergoing cardiac surgery and is associated with prolonged hospitalization, increased morbidity, and poor recovery. Currently, effective pharmacological strategies for preventing POD remain limited.
This study aims to evaluate whether perioperative administration of dezocine can reduce the incidence of postoperative delirium in elderly patients undergoing cardiopulmonary bypass cardiac surgery.
This is a prospective, randomized, controlled clinical trial conducted at Fuwai Hospital. Eligible patients aged 65 years or older undergoing elective cardiopulmonary bypass cardiac surgery will be randomly assigned to receive either dezocine or normal saline control in a 1:1 ratio. Patients in the dezocine group will receive intravenous dezocine (0.1 mg/kg) before anesthesia induction and again before transfer out of the operating room. At each administration time point, dezocine will be diluted with normal saline to a total volume of 6 mL and infused intravenously over 3 minutes. Patients in the control group will receive equivalent volumes of normal saline at the corresponding time points.
The primary outcome is the incidence of postoperative delirium within 7 days after surgery. Secondary outcomes include delirium characteristics, postoperative recovery outcomes, pain scores, opioid consumption, sedation status, and perioperative complications.
This study will investigate the potential role of dezocine as a preventive strategy for postoperative delirium in high-risk elderly cardiac surgery patients.
