Background And ObjectivesA significant number of children undergo surgery experience high levels of anxiety in the presurgical period. The aim of this study is to investigate which intervention is more effective in reducing preoperative anxiety.Methods/MaterialsThe sample was composed of 75 subjects (aged 5-12 years) who had to undergo minor day surgery. Children were randomly assigned to: the Clowns group (N = 25) accompanied to the preoperative room by the clowns and by a parent; Premedication group (N = 25) premedicated with oral midazolam and accompanied to the preoperative room by one parent; or the Control group (N = 25) only accompanied by one parent. Anxiety in the preoperative period was measured by using the Modified Yale Preoperative Anxiety Scale (m-YPAS). Parental anxiety was measured by using the State-Trait Anxiety Inventory (STAI Y-1/Y-2).ResultsThe Clown group was significantly less anxious during the induction of anesthesia compared with Premedication group and Control group. There were not any significant differences between Control group and Premedication group. There was an increased level of anxiety in the induction room in comparison with the waiting room: this difference was statistically significant for Control group and Premedication group, whereas it was not significant in Clown group.ConclusionsPPIA+clown intervention is more effective in reducing anxiety in children during the preoperative period than PPIA alone or PPIA+oral midazolam.© 2010 Blackwell Publishing Ltd.
