NCT06353516

Brief Summary

The goal of this clinical trial is to compare the permeability of blood-brain barrier between the intravenous anesthesia group and the inhalation gas anesthesia group in the elderly patients undergoing surgery. The main questions it aims to answer are:

  • \[Is the permeability of blood-brain barrier between the intravenous anesthesia group and the inhalation gas anesthesia group in the elderly patients different?\]
  • \[Is the incidence of postoperative cognitive dysfunction between the intravenous anesthesia group and the inhalation gas anesthesia group different?\] Participants will be anesthetized with different categories of anesthetics.
  • Intravenous anesthetics
  • Inhalation gas anesthetics

Outcome Measures

Primary Outcomes (1)

  • Concentration of serum S100B levels

    Levels of S100B will be obtained from venous blood samples collected before surgery, at the end of surgery, 4 hours after surgery, and 1st day after surgery.

    before surgery, at the end of surgery, 4 hours after surgery, 1st day after surgery

Secondary Outcomes (7)

  • Incidence of Delirium

    during 7 postoperative days or until discharge if the postoperative hospital stay is shorter than 7 days

  • Incidence of Postoperative Cognitive Dysfunction

    before surgery, 3 months after surgery

  • Concentration of serum albumin

    before surgery, at the end of surgery, 4 hours after surgery, 1st day after surgery

  • Concentration of serum CRP

    before surgery, at the end of surgery, 4 hours after surgery, 1st day after surgery

  • Concentration of serum IL6 levels

    before surgery, at the end of surgery, 4 hours after surgery, 1st day after surgery

  • +2 more secondary outcomes
