Preoperative Change of mYPAS in Different Group

Values are mean ± SD or number. M group: midazolam 0.15 mg/kg IV premedication. S group: intervention with smart phone application. SM group: midazolam 0.05 mg/kg IV premedication and intervention with smart phone application. No anxiety: the number of children whose scores indicated no anxiety (mYPAS score < 30) at operation room. MDZ add.: the number of children who needs additional midazolam premedication 0.05 mg/kg IV for high mYPAS score (mYPAS > 70). ^*P < 0.05 compared with holding area. In all three group, the preoperative anxiety scale after intervention and in operation room were lower than the holding area (P < 0.01). A comparison of mYPAS scores between each group showed that the S group reduced anxiety lower than M group (P < 0.01), and the SM group exhibited significantly lower anxiety than the two other groups (P < 0.01). The number of no anxiety in each group showed that the SM group had the significantly highest number than the two other groups (P < 0.01).
