Use of the Equimolar Mixture of Oxide Nitrous and Oxygen (EMONO) Associated With Audiovisuals in Children

Children experience numerous painful experiences from nursing procedures: peripheral venous access placement is the main cause of procedural pain. As much as pharmacological and nonpharmacological tools are known, their application during venipuncture is not systematic by children's hospitals. Among pharmacological tools, the Equimolar Mixture of Nitrogen Protoxide and Oxygen (EMONO) provides adequate protection from procedural pain through inhalation of the gas mixture at least 3 minutes before the procedure. Literature reports that the combination of nonpharmacological distractive tools and pharmacological interventions increases their analgesic effect. The aim of the study is to measure children's cooperation during procedure (primary outcome), pain perception and side effects when EMONO is combined with audiovisuals compared with EMONO alone in peripheral venous access placement.
