摘　　要：目的调查分析X射线引导下空气灌肠整复术中患儿的受照剂量,为降低患儿辐射损伤风险提供依据。方法收集接受空气灌肠整复术治疗的肠套叠患儿的资料;筛选、整理出3个不同年龄段的高、中、低组实验的条件,利用仿真人体模型模拟手术现场,借助热释光系统对患儿受照剂量进行测量。结果肠套叠患儿在X射线引导下行空气灌肠整复治疗,成功率为88%(含再套叠者)、早期再套叠率为8%。该治疗中患儿有效剂量范围为0.57~12.33 mSv,吸收剂量较高的组织、器官多集中于胸部、腹部。结论不同实验组患儿受照剂量差距较大,受照剂量不容小觑。建议操作者优选超声引导,若选择X射线引导,应尽量减少曝光时间,并为患儿规范佩戴防护用品,从而保障患儿健康。Objective To investigate the dose of radiation in children under going X-ray-guided air enema reduction,and to provide a basis for reducing the risk of radiation injury in pediatric patients.Methods Data were collected from children with intussusception who were treated with air enema.The experimental conditions of high,medium,and low doses of three age groups were analyzed.Phantoms were used to simulate the operation,and the radiation dose was measured using a thermoluminescence system.Results In children with intussusception,the success rate of air enema under the guidance of Xray was 88%(including secondary intussusception),with anearly re-intussusception rate of 8%.The effective dose of treatment ranged from 0.57 to 12.33 mSv,and the tissues and organs with high absorbed dose were mainly in the chest and abdomen.Conclusion Children in different groups are exposed to significantly differentand relatively high doses.The operators are recommended to use ultrasonic guidance.With X-ray guidance,the exposure time should be minimized and protective equipment for children should be used.
