Clinical Trial Summary

The purpose of this study is to assess the effectiveness of nitrous oxide/oxygen administration in reducing the discomfort of intranasal midazolam administration for moderate sedation for dental procedures.


Clinical Trial Description

This study will determine the effectiveness of two different concentrations of nitrous oxide for reducing the pain of intranasal midazolam when given for subjects already planned for moderate sedation for completion of dental procedures in the pediatric dental clinic. Moderate dental sedation is useful because it helps relieve anxiety and make the dental procedure less memorable and more comfortable for the patient. Sedation appointments typically go smoothly when the patient is calm rather than when the patient is upset. Giving midazolam through the nose can be painful and the dental provider risks upsetting a patient and causing the sedation appointment to fail. Therefore, the goal of this study is to test whether nitrous oxide administration is effective in reducing the pain from intranasal midazolam administration. The effectiveness will be measured by the primary outcome of heart rate pre- and post- midazolam administration for the two randomly assigned study arms. The first study arm will be given 30% nitrous/70% oxygen and the second study arm will be given 70% nitrous/30% oxygen prior to the midazolam administration. The secondary outcome will compare subject, dental provider, and the parent/guardian answers to questions regarding the subject's experience pre- and post- midazolam administration. The investigators hypothesize lower changes in heart rate and less pain reported following midazolam administration in subjects given 70% nitrous oxide. ;
