Acid secretion studies were carried out in 50 patients. Fluoroscopy or a modified water recovery test was used to position the nasogastric tube. For every patient each positioning procedure was used on one of two consecutive days, and acid output studies were performed. The tests were assessed by two observers and accepted or rejected. Analysis revealed no significant differences between the acid studies irrespective of the method used for positioning the nasogastric tube. Rejection rates by either procedure showed no significant difference. Practical considerations favour the continued use of water recovery as a means of positioning the nasogastric tube for gastric secretion studies.
对50名患者进行了胃酸分泌研究。使用荧光镜检查或改良的水回收试验来放置鼻胃管。对于每位患者,在连续两天中的一天使用每种放置方法,然后进行胃酸分泌量研究。由两名观察者对测试进行评估并决定是否接受。分析表明,无论使用何种方法放置鼻胃管,胃酸分泌研究之间均无显著差异。两种方法的拒绝率均无显著差异。从实际考虑出发,支持继续使用水回收法作为在进行胃分泌研究时放置鼻胃管的一种方法。
