Abstract
Pain is defined by the International Association for the Study of Pain (IASP) as "an unpleasant sensory and emotional experience associated, or similar to that associated, with actual or potential tissue injury" (Vidal Fuentes, 2020). It is vital to control the pain before performing techniques that involve this painful experience, as well as the awareness of all health professionals to apply the different resources and respect the times of action of effect. Thus, it has been shown that the use of nitrous oxide (N2O) is an optimal alternative to mitigate painful effects with few recorded adverse effects, these being mostly mild and known. It is well accepted by parents, who would again accept the use of gas in future procedures (Capapé, 2008).This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
