摘要
目的通过比较两组患儿的检查成功率,探讨角色转换干预法在儿童头颅MRI检查中的价值。方法选取484例行MRI检查的患儿,随机分配到干预组和对照组,对照组只交代MRI检查时的注意事项,干预组除交代MRI检查时的注意事项外还进行角色转换干预,然后对患儿的图像进行主观及客观评价,主观评价及客观评价均合格则认为该患儿MRI检查成功。对于患儿的年龄采用方差分析,患儿性别和检查成功的人数进行卡方检验。结果 4~4.9岁患儿干预组检查成功率(77%)较对照组(51%)提高了26%(χ^2=6.99,P=0.008);5~5.9岁患儿干预组检查成功率(84%)较对照组(65%)提高了19%(χ^2=4.86,P=0.028);6~6.9岁患儿干预组检查成功率(86%)较对照组(63%)提高了23%(χ^2=6.36,P=0.012);其余年龄组患儿干预组较对照组检查成功率未见明显提高。结论角色转换干预法能够提高4~6.9岁患儿头颅MRI检查成功率。
Objective To investigate the value of role reversal intervention by comparing the success rate of two groups of children during the MRI examination. Methods 484 patients were enrolled and distributed into Intervention group and control group randomly.The children in the control group were only told the notes during the examination and the children in the Intervention group were not only told the notes during the examination but also performed role reversal intervention. The image quality was evaluated subjectively and objectively,both subjective and objective evaluation were qualified,and the result of MRI examination was considered to be successful. The age of the children was analyzed by variance,and the gender of the children and the numbers of successful patients were tested by chi-square test. Results The success rate of the intervention group was 77% among children of 4-4.9 years,26% higher than the 51% of the control group(χ~2=6.99,P=0.008. The success rate of the intervention group was 84% among children of 5-5.9 years and 19% higher than the 65% of the control group(χ~2=4.86,P=0.028). The success rate of the intervention group was 86% among children of 6-6.9 years,23% higher than the 63% of the control group(χ~2=6.36,P=0.012). No significant improvement was found in other groups. Conclusion Role reversal intervention can improve the success rate of brain MRI examination in children aged 4-6.9 years.
