胃液分析是辅助诊断胃十二指肠疾病和了解胃分泌功能的常用方法之一。过去由于测定方法不够标准化,命名陈旧,因此逐渐失去重视。近十余年来,在方法学上有了较大进步,如能严格控制有关因素,有针对性地进行试验,胃液分析还是一项有实用价值的诊断方法。影响胃液分析的因素和操作中应注意的事项胃液除胃酸外,还有胃的非酸性分泌液,内含粘蛋白、中性氯化物、重碳酸盐和胃蛋白酶原等,它们具有稀释和缓冲胃酸的作用。此外,咽下的唾液以及十二指肠液和胆汁的返流对胃酸也有缓冲和稀释作用。胃管的插入和留置是一个不良的精神因素,可能影响胃液的分泌。胃的排空也能影响胃酸的测定,通过胃管
Gastric juice analysis is one of the commonly used methods to help diagnose gastroduodenal diseases and to understand gastric secretion. In the past due to the lack of standardization of measurement methods, the name of obsolete, it gradually lose weight. In the past decade or so, there has been a great improvement in methodology. For example, we can strictly control the relevant factors and carry out targeted tests. Gastric juice analysis is still a valuable diagnostic method. Factors that affect the analysis of gastric juice and the operation should pay attention to matters In addition to gastric acid gastric juice, there are non-acidic gastric secretion, containing mucin, neutral chloride, bicarbonate and pepsinogen, which have a dilution and Buffer the role of stomach acid. In addition, swallowing of saliva and duodenal fluid and bile regurgitation also buffer and dilute stomach acid. Gastric tube insertion and retention is a poor psychiatric factor that may affect the secretion of gastric juice. Gastric emptying can also affect the determination of gastric acid, through the stomach tube
