Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants receiving moderate sedation for a dental procedure will be recruited and divided into one of two study arms.

Primary Study Purpose

TREATMENT

Blinding Strategy

DOUBLE

Participants Caregivers

Sedation provider who will administer the pain scale tests and the participant will be masked to the subject's assigned study arm (30% or 70% nitrous oxide with midazolam). The attending pediatric dentist and dental assistant will not be blinded for patient safety.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

30% Nitrous Oxide with Midazolam

30 percent nitrous oxide/70 percent oxygen will be administered for 5 minutes prior to intranasal midazolam.

Group Type EXPERIMENTAL

Nitrous Oxide

Intervention Type DRUG

Nitrous oxide will be given prior to determine if it reduces pain from intranasal midazolam administration. Nitrous oxide is a minimal sedation drug used as an inhaled gas to reduce anxiety and produce anxiolysis and analgesia during dental procedures.

Midazolam

Intervention Type DRUG

Intranasal midazolam will be given after nitrous oxide administration.

70% Nitrous Oxide with Midazolam

70 percent nitrous oxide/30 percent oxygen will be administered for 5 minutes prior to intranasal midazolam.

Group Type EXPERIMENTAL

Nitrous Oxide

Intervention Type DRUG

Nitrous oxide will be given prior to determine if it reduces pain from intranasal midazolam administration. Nitrous oxide is a minimal sedation drug used as an inhaled gas to reduce anxiety and produce anxiolysis and analgesia during dental procedures.

Midazolam

Intervention Type DRUG

Intranasal midazolam will be given after nitrous oxide administration.
