Sorensen建议用电测法直接测定胃内pH,能更准确地反映胃的产酸功能。此方法比滴定法优越,因为当pH超过2.5,滴定法常常需要测定定离酸的缺乏与否。并且,胃内pH的测定未打破自然消化过程的反射作用链。材料与方法应用两个橄榄形的探针样式带有两个电极,其中一个是在胃体部,另一个在胃窦部。在胃的不同部位同时测定pH值。在插入探针后,用放射线检查其位置;末端电极是在幽门前,第二个电极在胃体。应用pH—340仪器测定pH。每隔5分钟记录
Sorensen suggested that direct measurement of pH in the stomach by electrical measurements would more accurately reflect the gastric acid production function. This method is superior to titration because when the pH exceeds 2.5, the titration often requires the determination of the absence or absence of the acid. Also, the measurement of pH in the stomach did not break the chain of reflection in the natural digestion process. Materials and Methods Application Two olive probe styles with two electrodes, one in the stomach and the other in the antrum. Simultaneous determination of pH in different parts of the stomach. After inserting the probe, check its position with radiation; the tip electrode is in front of the pylorus and the second electrode is in the corpus. pH was measured using a pH-340 instrument.
