Effectiveness of Children Experiencing Nitrous Oxide/Oxygen Inhalation Sedation at an Assessment Visit Before Having Treatment.

Apart from the Lead researcher, a dental nurse assisted with the dental treatment on every appointment. A specially trained sedation nurse was responsible for the monitoring during sedation. The Porter Brown inhalation sedation machine (RA Services, Keighly, W. Yorkshire, UK) was used. Once the appropriate nasal hood was selected, 100% O2 was introduced for 1-2 minutes. Following that, the level of N2O was increased in 10% increments until signs of sedation were observed. The endpoint was between 30-40% nitrous oxide.
