The association of preprocedural anxiety and the success of procedural sedation in children

Abstract

Purpose: To investigate the association between a child's preprocedural state anxiety and the success of sedation.

Methods: A consecutive sample of children aged 2 through 17 years requiring sedation for a procedure was enrolled. Pain, preprocedural anxiety (range, 0-9), and success of sedation (10=most successful) were measured.

Results: Fifty-nine patients were enrolled. The median age was 7 years. The median anxiety score was 1.0 (interquartile ratio, 0-3). Pain and anxiety were weakly correlated (r=.21, P>.10). The mean sedation score was 7.8 (+/-2.2). Preprocedural anxiety and successful sedation were inversely correlated (r=-0.31, P=.002). Sedation was successful in 81% of children with anxiety scores below the median and 52% with anxiety scores above the median (P=.02). Children with low anxiety were 3.8 times more likely to be successfully sedated (95% confidence interval, 1.19-12.14).

Conclusion: Our data suggest that preprocedural state anxiety is associated with the success of sedation in children.
