Insights
Nitrous oxide may slightly improve diazepam sedation in young children by reducing crying and movement. However, this effect is not consistent across all pediatric patients undergoing dental procedures.
Area of Science:
- Pediatric Dentistry
- Anesthesiology
- Sedation Techniques
Background:
- Diazepam is commonly used for pediatric sedation.
- Optimizing sedation quality in young children is crucial for procedural success.
- Investigating adjuncts to enhance sedative effects is an ongoing area of research.
Purpose of the Study:
- To evaluate if nitrous oxide (N2O) augments diazepam sedation in young children.
- To assess the impact of N2O on reducing crying and movement during sedation.
- To determine if N2O improves the overall quality of sedation in pediatric patients.
Main Methods:
- A randomized crossover study involving 24 children (mean age 32 months).
- Children received oral diazepam (0.5 mg/kg) with and without nitrous oxide (50% N2O/50% O2).
- Sedation quality was assessed by crying, movement, and overall evaluation; vital signs were monitored.
Main Results:
- Successful sedation occurred in 83% of administrations.
- Overall sedation quality was rated as better with nitrous oxide in 56% of cases.
- Vital signs remained stable, with transient elevations during specific procedural steps.
Conclusions:
- Nitrous oxide may offer a slight augmentation to diazepam sedation in young children.
- The benefit of nitrous oxide on diazepam sedation is not uniform for all pediatric patients.
- Further research may be needed to identify patient factors influencing response to combined sedation.
Abstract:
This study was performed to test the hypothesis that nitrous oxide augments the effects of diazepam sedation of young children by reducing crying and movement and improving the overall quality of sedation. Twenty-four children (mean age of 32 months) were sedated on two occasions with two different treatment regimens. All subjects received a standard oral dose of 0.5 mg/kg of diazepam with and without nitrous oxide during each of two treatment visits. During one visit, the subjects received 50% nitrous oxide and 50% oxygen for the first 20 min followed by 100% oxygen for the balance of the procedure and, during the second visit, the reverse regimen was used. All subjects were restrained in a Papoose Board (Olympic Medical, Seattle, WA) with an auxiliary head restraint. Successful sedation, as evidenced by lack of crying or movement that interrupted treatment, occurred in 83% of administrations. Vital signs remained essentially unchanged throughout all treatment with the exception of transitory elevation of the pulse and respiratory rates, which usually occurred when the mouth prop was inserted, local anesthesia was administered, and the rubber dam was placed. When the evaluation of the overall sedation was compared with and without nitrous oxide, it was better with nitrous oxide 56% of the time, worse 13% of the time, and the same in the remaining 31% of the comparisons. It is concluded that nitrous oxide may slightly augment the effect of diazepam sedation of young children, but it does not do so uniformly for all children receiving sedation.
