Nitrous Oxide Prior to Intranasal Midazolam for Moderate Dental Sedation in Pediatric Patients
- Registration Number
- NCT04083105
- Lead Sponsor
- Children's Hospital Colorado
- Brief 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.
- Detailed 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.

Group Intervention Description 30% Nitrous Oxide with Midazolam Midazolam 30 percent nitrous oxide/70 percent oxygen will be administered for 5 minutes prior to intranasal midazolam. 70% Nitrous Oxide with Midazolam Midazolam 70 percent nitrous oxide/30 percent oxygen will be administered for 5 minutes prior to intranasal midazolam. 30% Nitrous Oxide with Midazolam Nitrous Oxide 30 percent nitrous oxide/70 percent oxygen will be administered for 5 minutes prior to intranasal midazolam. 70% Nitrous Oxide with Midazolam Nitrous Oxide 70 percent nitrous oxide/30 percent oxygen will be administered for 5 minutes prior to intranasal midazolam.
- Primary Outcome Measures
Name Time Method Heart rate through the study completion, an average of 2 years Measured in beats per minute with range from 50-190 bpm. A great change in heart rate indicates more pain and less effect of the nitrous oxide. Heart rate is an autonomic reflex to determine the effect of mental and physical stressors including painful stimuli. The participants resting heart rate will be compared to the heart rate immediately after intranasal midazolam administration for a change in heart rate value.
- Secondary Outcome Measures
Name Time Method Wong-Baker Faces scale for pain through the study completion, an average of 2 years Scale from 0 (no hurt) to 10 (hurts worst). A higher score indicates more pain. Wong-Baker Faces scale will be recorded from the subjective standpoint of the participant.
Visual analog scales (VAS) for pain through the study completion, an average of 2 years Scale from 1 (no pain) to 10 (most possible pain). A higher score indicates greater pain. VAS will be obtained from the subjective standpoint of the parent/guardian of the parent and the dental provider during time points before and after the administration of intranasal midazolam.
Visual analog scales (VAS) for fear through the study completion, an average of 2 years Scale from 1 (no fear) to 10 (very fearful). A higher score indicates greater fear. VAS will be obtained from the subjective standpoint of the parent/guardian of the parent and the dental provider during time points before and after the administration of intranasal midazolam.
