目的对小儿上消化道气钡双重造影检查,方法的改进,探讨其实用价值。方法从钡剂的调制到检查的每一个环节严格把关。钡剂调制成200%(W/V)浓度混悬液,用开水配制,连续搅拌5min以上。检查前口服产气粉一袋,用5ml温开水服送,以后前式站立位服下量好的30ml钡剂,立即将床放平后迅速左转成仰卧位点片,再向左转成后斜位点片,向右转成右斜位点片,爆光时嘱咐患儿深吸气后呼尽气闭住气。然后服完全部钡剂透视观察胃,十二指肠的充盈相。结果50例胃内产气充分,胃黏膜皱襞表层上钡剂涂布均匀,附着好;胃壁线、十二指肠球壁线,胃小区、胃小沟及病灶的对比相显示效果良好。仰卧位,左后斜位为避免十二指肠充盈的最佳体位;30ml钡剂是第一口服下的最适容量,即使钡剂在胃黏膜皱襞表层上涂布均匀,以能防止钡剂在胃窦部积滞。结论本方法对小儿上消化道钡双重造影检查具有可行性,实用性,双对比相显示效果良好及较高的诊断价值。
Objective To improve the method and the method of double contrast barium in upper gastrointestinal tract in children and discuss its practical value. Method from barium modulation to check every aspect of strict control. Barium modulation to 200% (W / V) concentration suspension, prepared with boiling water, continuous stirring for 5min or more. Check before oral gas powder bag, with 5ml warm water to send service, after the former standing position to take a good dose of 30ml barium, immediately after the bed quickly turn left into a supine position, and then turn left After the diagonal film, right turn into the right diagonal film, when the child asked the child to breathe deep breathing breath exhale. Then take the whole part of the barium perspective observation of stomach, duodenum filling phase. Results Gas production in the stomach was adequate. The barium coating on the surface of gastric mucosa was uniform and well attached. The contrast of gastric wall, duodenal wall, gastric area, gastric minor groove and lesion showed good results. Supine, left oblique position to prevent duodenal filling the best position; 30ml barium is the first oral optimum capacity, even if the barium in the gastric mucosa folds on the surface coating evenly to prevent barium Stagnation in the antrum. Conclusion This method is feasible and practicable for the double contrast biopsy of upper gastrointestinal tract in children. The double contrast phase shows a good effect and a high diagnostic value.
