X射线对小儿肠套叠诊治剂量优化价值探讨

目的 探讨小儿肠套叠在数字脉冲透视整复中的辐射剂量优化,为降低小儿在X射线透视整复中的辐射剂量提供一种切实可行的方法。方法 通过调研相关文献并结合研究的目的和原理,采用数字胃肠机低脉冲透视对小儿肠套叠胃肠整复治疗。结果 实验组(脉冲率=3P/s)60例,影像诊断的符合率为100%,空气灌肠整复的成功率为95%;对照组(脉冲率=7.5P/s)60例,影像诊断的符合率为100%,空气灌肠整复的成功率93.3%。两者在诊断符合率与整复成功率无明显差别,但在所接受辐射次数上实验组是对照组的39.25%。结论 降低数字胃肠机的透视脉冲率既可满足临床诊断和治疗需求,又可以降低肠套叠患儿的辐射剂量,值得在小儿肠套叠数字透视整复治疗中应用。

Study of Dose Optimization for X-ray in Pediatric Intussusception Diagnosis and Treatment

Objective To explore dose optimization of pediatric intussusception reconstruction by digital pulse fluoroscopy and provide a feasible method to reduce radiation dose in fluoroscopy reconstruction.Methods By reviewing related literatures and combining objective as well as principle of this study, perform air enema by using digital gastrointestinal machine with low pulse on intussusception children.Results In experimental group with 60 cases, the accordant rate of diagnosis was 100%, and the reset success rate was 95%. In control group with 60 cases, the accordant rate of diagnosis 100% and reset success rate 93.3%. There was no significant difference between the two groups in the accordant rate of diagnosis and reset success rate, while in the time of radiation, experimental group was about 39.25% of the control group.Conclusion Reducing pulse can not only meet the demand of clinical diagnosis and treatment, but also reduce radiation dose in children with intussusception. It is worthy of being applied to air enema reconstruction by digital pulse fluoroscopy.
