The Nociception Level (NoL) is an index obtained via a non-invasive monitor, that is currently used to assess nociception in anesthetized adults. The NoL index varies from 0 to 100. It increases in response to nociceptive stimuli. The objective of this study was to investigate if the NoL index also indicates the level of nociception in anesthetized children. In children anesthetized according to standard practice, before surgical incision, three 5-seconds stimulations will be performed with different intensities (10, 30 and 60 milliamps). The order of the stimulations intensities will be randomized. The hypothesis of study is that the intensity of stimulation will influence the magnitude of NoL-index increase in response to the stimulation.

NoL variation = [(Maximal NoL value in the 5 minutes following the stimulation) - (NoL before stimulation)] / [NoL before stimulation]
Timeframe: 5 minutes after stimulation
