摘　　要：目的:探讨乐园化引导干预对儿童放疗摆位精度的影响。方法:选取2020年3月~2022年5月在中山大学肿瘤防治中心放疗的儿童患者作为研究对象,按照是否参与乐园化引导干预分为试验组(24例)和对照组(21例)。试验组儿童患者在每次放疗前进行儿童乐园化诱导心理干预,待儿童患者完成心理适应后进行治疗;对照组实施常规放疗准备后治疗。比较两组儿童患者放疗实施的摆位精度。结果:试验组在左右(LR)、头脚(SI)、腹背(AP)方向的摆位误差分别为(-0.32±2.18)、(-0.12±2.24)、(-0.17±2.32)mm,对照组分别为(-0.93±1.91)、(0.79±1.75)、(-0.63±1.97)mm。两组摆位误差比较,在LR和SI方向的差异有统计学意义(LR:t=2.28, P=0.02;SI:t=-2.58, P=0.01),而AP方向的差异无统计学意义(LR:t=1.63, P=0.11)。结论:乐园化引导干预可以提高儿童患者放疗的依从性,进而提高放疗的摆位精度,具有显著的临床应用意义和推广价值。Objective To explore the effect of playful situational intervention on the positioning accuracy in radiotherapy for children. Methods Children who received radiotherapy in Sun Yat-sen University Center Cancer from March 2020 to May2022 were enrolled in the study. The patients in experimental group(n=24) were given playful situational intervention before radiotherapy, and the radiotherapy was carried out after psychological adjustment. Those in control group(n=21) received radiotherapy after routine preparation. The positioning accuracy in radiotherapy was compared between two groups. Results The setup errors in left-right(LR), superior-inferior(SI) and anterior-posterior(AP) directions were(-0.32±2.18),(-0.12±2.24),(-0.17±2.32) mm in experimental group, and(-0.93±1.91),(0.79±1.75),(-0.63±1.97) mm in control group. There were significant differences in setup errors between two groups in LR and SI directions(LR: t=2.28, P=0.02;SI: t=-2.58, P=0.01), but not in AP direction(t=1.63, P=0.11). Conclusion Playful situational intervention can improve patient compliance,thereby improving the positioning accuracy of radiotherapy, with significant clinical significance and popularization value.
