EEG and ANI Guided Anesthesia and Quality of Recovery

Официальное название

Quality of Recovery After Electroencephalogram and Nociception Level-guided Versus Standard Anesthesia Care in Female Patients Undergoing Laparoscopic Gynecological Surgery: A Randomized Controlled Trial

Обзор

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.

Подробное описание

Adult women scheduled to undergo laparoscopic gynecologic surgery will be screened for eligibility. Patients will be randomly allocate to either the EEG-and-ANI-guided group or usual care group.

In the guided group, sevoflurane concentration will be titrated according to EEG monitoring. Intraoperative infusion of remifentanil will be titrated by ANI monitoring.

In the usual care group, EEG and ANI sensor will be attached to patients, but EEG and ANI monitor will be blinded to the attending anesthesiologists. The anesthesiologists will provide a standard care of our institution for anesthetic and analgesic titration. In brief, hemodynamic variables and clinical situations will be used to titrate the anesthetic depth and analgesic dose.

Blinded investigator will assess quality of recovery questionnaire-15 at postoperative day 1 and 2.

Вмешательства

• Процедура EEG-and-ANI-guided anesthesia
  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.
• Процедура standard anesthesia
  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.
• Препарат Sevoflurane and remifentanil
  For anesthetic maintenance, balanced anesthesia with sevoflurane inhalation and target controlled infusion of remifentanil will be performed.
• Устройство EEG and ANI
  EEG monitoring using SEDline (Masimo, Irvine, California, USA) and Analgesia Nociception Index (ANI; MetroDoloris Medical Systems, Lille, France) monitoring will be performed.
