NoL and BIS Monitoring on Patients Recovery and Safety After Surgery (CINAAMON)
Evaluation of the Combined Intraoperative Depth of Analgesia (NoL) and Depth of Anesthesia (BIS) Monitoring on the Patients' Recovery and Safety After Surgery: A Pilot Study
Study Overview

Conditions
Intervention / Treatment
Detailed Description
Hypothesis is that the intraoperative use of the combination of 1) the NoL index (given by the PMD200TM monitor, Medasense LTD inc, Ramat, Israel) to monitor pain levels and to guide opioids' administration during surgery, and 2) the BIS index (Medtronic, St-Laurent, QC, Canada) to monitor the depth of hypnosis during anesthesia and to guide the administration of anesthetic halogenous gases, will improve the quality of recovery as well as the safety after anesthesia in ERAS (Early Rehabilitation After Surgery) patients undergoing colonic surgery under general anesthesia + epidural analgesia.
This study will compare a group of patients monitored by the classical monitoring (with anesthesia/analgesia guided by these classical parameters: heart rate, blood pressure; Control "C" group; no BIS, no NoL) to a group of patients monitored by the same classical monitoring implemented with the NoL/BIS indices (with analgesia/anesthesia guided by these 2 indices; Monitoring "M" group).
The primary objective of the study will be the total consumption of desflurane that is expected to be significantly reduced in the M group. Secondary objectives will be evaluating safety and side effects of anesthesia and opioids and we expect a reduction of the following parameters: time for awakening from anesthesia, time for extubation, time for transfer to PACU, intraoperative opioid consumption, opioid consumption in PACU and for 48h, time for readiness for discharge from PACU, incidence of adverse effects such as: nausea-vomiting / sedation / respiratory depression / itching / dizziness / cognitive dysfunction in PACU and for 48h, satisfaction of the patients at 24 and 48hs, pain scores at rest and at mobilization in PACU, at 24h and 48h. Quality of postoperative recovery after surgery and treatment satisfaction are also expected to be higher in the M group than in the C group.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Control (C Group )
Intervention for intraoperative analgesic administration will be based on heart rate and blood pressure variations.
Intervention for intraoperative hypnotice/desflurane administration will based on keeping the MAC at 0.8.
|
Remifentanil i.v. infusion will be run between 0.03 and 0.15 mcg/kg/min and boluses (0.4mcg/kg) will be given to keep a baseline mean arterial pressure between 10% of variation. Once intubated, the maintenance of anesthesia will be achieved with: desflurane set at 1 MAC to start, then ajusted to 0.8 MAC. |
Experimental: Monitoring (M Group )
Intervention for intraoperative analgesic administration will be based on the NOL index (to keep it below 25).
Intervention for the desflurane administration will be based on the BIS index (to keep it between 40-60).
|
Remifentanil i.v. infusion will be run between 0.03 and 0.15 mcg/kg/min and boluses (0.4mcg/kg) will be given to keep a NoL index between 10-20. Once intubated, the maintenance of anesthesia will be achieved with: desflurane set at 1 MAC to start, then adapted to the BIS between 45-55.
