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. |
- 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 ]∆HR = [HR maximal value in the 3 minutes following the stim] - [HR before stim] Heart rate expected to increase after stim.
