Predictors of pediatric sedation failure with initial dose of intranasal dexmedetomidine and oral midazolam

Abstract

Background

To assess the sedative failure rate over different dose combinations of intranasal dexmedetomidine and oral midazolam for procedural sedation.

Methods

This was a retrospective study. Four groups were established according to the initial dose of sedatives. The primary outcome was the sedative failure rate for different doses of the two-drug combination. The risk factors associated with sedation failure were analyzed.

Results

A total of 2165 patients were included in the final analysis. Of these, 394 children were classified as sedation failure after the initial dose of a combination of intranasal dexmedetomidine and oral midazolam. Although the initial doses of intranasal dexmedetomidine and oral midazolam administered to patients varied widely, no significant differences were detected in the sedation outcomes among the groups. Multivariate analysis showed that sedation history, a history of sedation failure, and echocardiography were independent risk factors for sedation failure after an initial dose of intranasal dexmedetomidine and oral midazolam. In contrast, patients undergoing lung function and MRI were more likely to be successfully sedated.

Conclusion

A combination of low-dose intranasal dexmedetomidine and oral midazolam provides adequate sedation efficacy without any increase in side effects, especially for patients undergoing MRI or lung function examination.

Impact

  • This is an original article about the risk factors of sedation failure with an initial dose of intranasal dexmedetomidine and oral midazolam for procedure sedation.

  • For patients undergoing echocardiogram, it is better to choose other sedatives, while a combination of intranasal dexmedetomidine and oral midazolam is a good option for patients undergoing MRI or lung function.

  • The selection of sedative drugs should be personalized according to different procedures.
