24小时胃内酸度分析有助于研究食物、药物对胃酸的影响,在新的抗分泌药物研究中占重要地位.其突出优点是可在近于日常生活的条件下进行较长时间的观察,这些条件不难实现,因而有利于对比研究.但由于白天无法测定胃酸分泌量,所测仅为胃内酸度,且不能判断有无十二指肠返流的影响.虽可在夜间收集全部胃液以估计夜间分泌量,然而由于是持续抽吸胃内容,难以反映真实生活中的胃内酸度.少
24-hour intragastric acidity analysis helps to study the effects of food and medicine on gastric acid, which plays an important role in the research of new anti-secrete drugs. Its outstanding advantage is that it can be observed for a long time under the condition of daily life, These conditions are not difficult to achieve, which is conducive to comparative studies.But due to the inability to determine the amount of gastric acid secretion during the day, the measured acidity is only the stomach, and can not determine the presence or absence of duodenal reflux.Although the night can collect all the gastric juice To estimate the amount of nocturnal secretion, however, because it is continuous pumping stomach content, difficult to reflect the true life of the stomach acidity.
