NCT05936671

Brief Summary

This study aims to assess whether electroencephalogram (EEG) and nociception level-guided anesthesia can improve quality of recovery after laparoscopic gynecological surgery compared with standard care. Patients will be randomly assigned to either EEG and Analgesia Nociception Index (ANI)-guided anesthesia group (EEG-and-ANI-Guided group) or usual care group (control group). Primary outcome is 15-item Quality of Recovery (QoR-15) score at postoperative day (POD) 1. Secondary outcomes included remifentanil consumption during anesthesia, occurrence of awareness with recall, incidence of undesirable intraoperative movement, emergence time, postoperative pain scores, quality of recovery score at POD 2, and length of hospital stay.

Outcome Measures

Primary Outcomes (1)

  • 15-item Quality of Recovery (QoR-15) at postoperative day (POD) #1

    The Korean version of 15-item Quality of Recovery (QoR-15) score. Each item uses an 11-point numeric rating scale. The sum of the scores of the 15 items ranges from 0 to 150, with a high score indicating good quality of recovery.

    24 hours after the end of surgery

Secondary Outcomes (19)

  • Remifentanil consumption during anesthesia

    During surgery, from the anesthetic induction to emergence of anesthesia

  • Occurrence of awareness with recall

    During the operation.

  • Incidence of undesirable intraoperative movement

    During the operation.

  • Intraoperative end-tidal sevoflurane minimum alveolar concentration (MAC)

    During the operation

  • Intraoperative time ANI <50 [%]

    During the operation.

  • +14 more secondary outcomes

Study Arms (2)

EEG-and-ANI-guided group

EXPERIMENTAL

During anesthetic maintenance, sevoflurane concentration will be titrated according to EEG monitoring. Sevoflurane concentration will be titrated to maintain intraoperative Patient state index (PSi) ≥ 35 and to avoid burst suppression. Intraoperative target-controlled infusion of remifentanil will be titrated to maintain intraoperative ANI between 50 and 70.

Procedure: EEG-and-ANI-guided anesthesiaDrug: Sevoflurane and remifentanilDevice: EEG and ANI

Usual care group

ACTIVE COMPARATOR

During anesthetic maintenance, the attending anesthesiologists will provide a routine standard care for anesthetic and analgesic titration. In brief, hemodynamic variables and clinical situations will be used to titrate the sevoflurane concentration and remifentanil infusion rates.

Interventions

During anesthetic maintenance, sevoflurane concentration will be titrated according to EEG monitoring. Sevoflurane concentration will be titrated to maintain intraoperative Patient state index (PSi) ≥ 35 and to avoid burst suppression. Intraoperative target-controlled infusion of remifentanil will be titrated to maintain intraoperative ANI between 50 and 70.

During anesthetic maintenance, the attending anesthesiologists will provide a routine standard care for anesthetic and analgesic titration. In brief, hemodynamic variables and clinical situations will be used to titrate the sevoflurane concentration and remifentanil infusion rates.

Usual care group

For anesthetic maintenance, balanced anesthesia with sevoflurane inhalation and target controlled infusion of remifentanil will be performed.

EEG-and-ANI-guided groupUsual care group

EEG monitoring using SEDline (Masimo, Irvine, California, USA) and Analgesia Nociception Index (ANI; MetroDoloris Medical Systems, Lille, France) monitoring will be performed.
