Brief Summary

Postoperative delirium in older adults is a common and costly complication after surgery. Propofol and sevoflurane are commonly used anesthetics to maintain sedation during spine surgery, and have different sedative and anti-inflammatory effects. The aim of this trial will be compare the impact of propofol versus sevoflurane on incidence of postoperative delirium in elderly patients after spine surgery.

Outcome Measures

Primary Outcomes (1)

  • Incidence of delirium after surgery

    Delirium is assessed twice daily (8-10 AM and 6-8 PM ) with the 3 minute diagnostic interview for Confusion Assessment Method.Researchers will review all progress notes and nursing documentation for delirium diagnoses, and a thorough medical record review process using the Chart-based Delirium Identification Instrument.

    Between postoperative day 1 to discharge or day 7, whichever came first

Secondary Outcomes (12)

  • The day of postoperative delirium duration among patients who developed delirium

    Time from first to last delirium-positive day. Between postoperative day 1 to discharge or day 7, whichever came first

  • The day of total delirium-positive days among patients who developed delirium

    Between postoperative day 1 to discharge or day 7, whichever came first

  • The types of delirium in patients who developed delirium

    Between postoperative day 1 to discharge or day 7, whichever came first

  • The intubation time in postanesthesia care unit (PACU)

    From the patient transfered into PACU to tracheal extubation. Within 24 hours after surgery.

  • The length of stay in in postanesthesia care unit (PACU)

    Within 24 hours after surgery.

  • +7 more secondary outcomes

Study Arms (2)

propofol group

OTHER

For patients in the propofol group, anaesthesia will be maintained with propofol infusion(target controlled infusion), of which the target concentration will be adjusted to maintain the BIS value between 40 and 60. Analgesia will be maintained with remifentanil(0.1-0.5ug/(kg.min)), muscle relaxation will be maintained with atracurium(10ug/(kg.min)). Propofol infusion will be stopped at the end of surgery.

Drug: propofol infusion

sevoflurane group

OTHER

For patients in the sevoflurane group, anaesthesia will be maintained with sevoflurane inhalation, of which the concentration will be adjusted to maintain the BIS value between 40 and 60. Analgesia will be maintained with remifentanil(0.1-0.5ug/(kg.min)), muscle relaxation will be maintained with atracurium(10ug/(kg.min)). Sevoflurane inhalation will be stopped at the end of surgery.

Drug: sevoflurane inhalation

Interventions
