Current Primary Outcome Measures  ICMJE
 (submitted: May 6, 2020)
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.

Heart rate Variation (∆HR) [ Time Frame: 3 minutes following tetanic stimulation ]

Descriptive Information
Brief Title  ICMJE Newborn Infant Parasympathetic Evaluation (NIPE) Index After Standardized Tetanic Stimulations Under General Anesthesia
Official Title  ICMJE 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
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.

Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description:
The research does not involve the evaluation or comparison of medical strategies.The order of application of the stimuli will be randomized according to a Latin square of order 3.
Masking: None (Open Label)
Primary Purpose: Diagnostic
Condition  ICMJE Anesthesia
Intervention  ICMJE
  • 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.

Study Arms  ICMJE Experimental: NIPE
  • Device: NIPE monitor
