Summary

N2O has been used during general anesthesia (GA) for more than 100 years. It is known to have anesthetic agents sparing effect. But small is know on his real analgesic effect during GA. So far, the only way to monitor pain during GA was based on vital signs that are not specific and not sensitive. Few devices tried to evaluated pain under GA during the last 2 decades. More recently, better devices were proposed such as the Physiodoloris device and the PMD200 device. The first offers an index called ANI based on heart rate variability (HRV) assessment. The second offers the NoL index based on the analysis of 5 parameters. The aim of the present study is to evaluate quantitatively the analgesic index of N2O during GA using the two indices ANI and NoL.

N2O exposure

The aim of this study is to evaluate the nociceptive response to a standardized forearm electrical stimulus applied to patients under GA, during surgery, at different End-Tidal concentrations of N2O (ET-N2O: 0%-50%-25%-0%), and to see if ANI and NoL indices show less pain when inhaled N2O is higher.
