Pediatric Emergency Suture Care: a Trial Comparing the Analgesic Efficacy of Hypnosis Versus MEOPA

Trial end date:
Target enrollment:
Participant gender:
This is a therapeutic, randomized, single center, two parallel-arm trial comparing pain control via "MEOPA" (equimolar mixture of nitrous oxide and oxygen) in one arm versus "Hypnosis + MEOPA if needed" in the second arm. The primary objective is to compare the two study arms in terms of efficacity for pain control according to the FLACC (Face Legs Activity Cry Consolability Observational Tool) behavioural scale.
