Brief Summary:
NIPE monitor is the recently developed pediatric version of the ANI monitor, which is used in adults to monitor analgesia during general anesthesia. In adults, under general anesthesia, ANI decreases after a nociceptive stimulation. The amplitude of this decrease is related to the intensity of the stim. This study aims to investigate if NIPE index decreases in the same manner after stimulations in anesthetized children.

Allocation: N/A

Primary Purpose: Diagnostic
Official Title: Newborn Infant Parasympathetic Evaluation (NIPE) Index After Three Standardized Tetanic Stimulations (10, 30 and 60 Miliamps) Performed in a Randomized Sequence Under General Anesthesia in a Pediatric Population
Actual Study Start Date : January 28, 2021
Estimated Primary Completion Date : July 2022
Estimated Study Completion Date : July 2022

Arm Intervention/treatment
Experimental: NIPE Device: NIPE monitor
NIPE monitor connected to the anesthetic station. No part of the device in contact with the patient. No action on patient or anesthesia. Automatic recording of Heart rate and NIPE index during the study period.

Procedure: Tetanic stimulations

Three tetanic stimulations will be performed (10-30 and 60 milliamps) under general anesthesia, before surgical incision.

Stims performed via the muscle relaxation monitor (used in standard practice in this population) Each stim lasts for 5 seconds. Interval between two stims : 3-5 minutes Order on intensities randomized by a latin square of order 3.

Primary Outcome Measures :
  1. Variation of NIPE index (∆NIPE) [ Time Frame: 3 minutes following tetanic stimulation ]

    ∆NIPE = [NIPE minimal value in the 3 minutes following the stim] - [NIPE before stim]

    NIPE varies from 0 to 100. Monitor displays one value per second. NIPE index expected to decrease after stim.

Secondary Outcome Measures :
  1. Heart rate Variation (∆HR) [ Time Frame: 3 minutes following tetanic stimulation ]
    ∆HR = [HR maximal value in the 3 minutes following the stim] - [HR before stim] Heart rate expected to increase after stim.
