NCT06788743

Brief Summary

The present study is a multicenter, randomized controlled clinical trial, which plans to enroll 450 diabetic patients aged more than 60 years. The participants will be randomly assigned in a 1:1 ratio and will receive either propofol or sevoflurane for intraoperative anesthesia maintenance to evaluate the impact of these two anesthetic drugs on postoperative delirium. The aim of our study is to explore whether the use of propofol for anesthesia maintenance in elderly diabetic patients undergoing elective non-cardiac major surgery can reduce the incidence of postoperative delirium. This study will provide new perspectives for improving perioperative management in elderly diabetic patients and optimizing anesthesia management strategies to reduce the risk of postoperative delirium.

Outcome Measures

Primary Outcomes (1)

  • the incidence of delirium

    Postoperative delirium will be assessed daily at 8:00 AM and 6:00 PM from postoperative days 1 to 7, or until discharge, using the 3D-CAM scale.

    within the first 7 postoperative days

Secondary Outcomes (4)

  • The severity of POD

    within the first 7 postoperative days

  • The duration of POD

    within the first 7 postoperative days

  • The length of hospital stay

    the first 7 postoperative days

  • Blood glucose levels

    before anesthesia induction (T0), 1 h and 2 h after incision (T1, T2), at skin closure (T3), before PACU discharge (T4), and on post-operative days 1 and 2 (T5, T6)

Other Outcomes (3)

  • Serum insulin levels

    at 1 h and 2 h after incision(T1, T2)

  • Serum inflammatory factor (IL-6) levels

    post-operative days 1 and 2 (T5, T6)

  • Serum neurodegenerative factor (S-100β protein) levels

    post-operative days 1 and 2 (T5, T6)
