Abstract
The purpose of this study was to compare effects of tablet-based interactive distraction (TBID; 1minute preseparation) with oral midazolam (15 to 45minutes of preseparation) on preoperative anxiety, emergence delirium, and postanesthesia length of stay in children, 4 to 12years undergoing outpatient surgery. Single-blinded prospective design with randomized assignment to TBID or oral midazolam group was conducted at a large pediatric hospital in southwestern United States. A total of 102 children and caregivers were enrolled. Outcome measures included anxiety scores at baseline, separation, and mask induction; postemergence delirium scores; caregiver ratings of child anxiety and satisfaction; and time from postanesthesia care unit arrival to discharge and posthospital behaviors. The TBID group demonstrated significantly lower anxiety at separation and mask induction (P < .001) and emergence delirium at 15minutes postawakening (P = .001), were extubated earlier (P = .007), arrived to phase II earlier (P = .03), and discharged earlier (P = .0001). TBID was more effective than oral midazolam in reducing preoperative anxiety, emergence delirium, and postanesthesia length of stay.
