Objective To evaluate the effect cooperation by using iPAD for preoperative intervention undergoing phimosiectomy. Methods Totally 60 children,undergoing phimosiectomy,were divided into the experimental group and the control group with 30 cases each by random digits table method. A conventional preoperative interview was performed in the control group. In the experimental group, the parents and the children would be given education about the environment of operation room and materials of educational propaganda by watching video in a preoperative interview,furthermore,the children got the entitlement to chose their favorite cartoons, which would be played in operation room. The age, weight, time for surgery and the number for general anesthesia were recorded. The anxiety level of the parents, assessed by Hamilton Anxiety Scale, were carried out before and after operation. The satisfaction score, coming from the parents for operation room work and the surgeon for the operation process were also carried out. Results The anxiety level of the parents assessed by Hamilton Anxiety Scale, after the operation,the number for general anesthesia and the time for surgery were(44.2 ± 7.4)points,11 cases, (11.9 ± 3.2)points in the experimental group,and (51.2 ± 6.0)points,28 cases,(17.7 ± 5.8)points in the control group, and there were significant differences(t =4.005, 4.704, χ2=10.978, all P<0.01). The satisfaction score, coming from the parents for operation room work and the surgeon for the operation process were higher than that in the control group (χ2=10.162, 14.836, P<0.01). Conclusions The cooperation of the children,undergoing phimosiectomy,could be improved significantly by the application of iPAD in preoperative interview.
