目的 探讨术前扮演护士角色对室间隔缺损患儿介入术后躁动及血管并发症发生的影响。方法 采用便利抽样方法选取2019年7月—2020年12月膜周部室间隔缺损行经导管介入封堵术的82例患儿作为试验组,在术前常规宣教的基础上,每2例患儿为1组进行护士角色扮演,提前模拟术后固定患儿术侧下肢并按压伤口的过程。2018年1月—2019年6月的79例患儿作为对照组,采用常规术前宣教。比较两组术后躁动评分及血管并发症发生率。 结果 躁动评分组间和时间存在交互效应（F=20.326,P<0.001）,简单效应分析显示离苏醒室时、术后1 h、术后2 h时,试验组躁动评分均低于对照组（P<0.05）,术后3 h两组患儿的躁动评分差异无统计学意义（P>0.05）;两组术后伤口渗血、血肿、动静脉瘘和假性动脉瘤发生率的差异均无统计学意义（P>0.05）。 结论 室间隔缺损患儿在术前扮演护士角色,可有效减轻患儿的躁动。

Objective To investigate the effects of role play as a nurse before surgery in children with ventricular septal defect. Methods A convenience sampling was used to recruit 82 children who underwent catheter interventional closure of perimembrane ventricular septal defect from July 2019 to December 2020 as the experimental group. On the basis of routine preoperative education,every 2 children were divided into 1 group for nurse role playing. The process of postoperative lower limb fixation and wound compression was simulated during the role play. Another 79 children were enrolled as the control group from January 2018 to June 2019 and routine preoperative education was provided. The postoperative agitation score and incidence of vascular complications were compared between the two groups. Results There were interaction effects between groups and time of agitation evaluation（F=20.326,P<0.001）. Simple effect analysis showed that the agitation score of children in the interventional group was lower than that of children in the control group when leaving the recovery room,1h and 2h after the surgery（P<0.05）. There was no statistically significant difference in the agitation score of the two groups at 3h after surgery（P>0.05）. There was no significant differences in the incidence of wound oozing,hematoma,arteriovenous fistula and pseudoaneurysm in the two groups（P>0.05）. Conclusion Children with ventricular septal defect should play the role of nurse before surgery,which can effectively reduce the irritability of children.
