自George采用双取样法以来,胃排空液体的测定仅需插一次胃管。用γ照相机作胃体外扫描既可免除插胃管,又可研究液态和固态混合餐的排空,但所用的仪器昂贵。闪烁检查法的效果相似,费用较低。本文就双取样法和闪烁检查法进行比较。材料和方法:测定对象包括14例正常人和15例已行迷走神经切除加引流术一年以上的患者。取牛乳、乳糖和水制成的乳剂500ml作为试验餐。在双取样
Since George uses the double sampling method, the determination of gastric emptying fluid need only be inserted once in the stomach tube. Using a gamma camera for extracorporeal scanning can eliminate the need to insert a gastric tube and study the emptying of liquid and solid mixed meals, but the instruments used are expensive. The flicker test works similarly and costs less. This article compares the double sampling method and the flicker inspection method. MATERIALS AND METHODS: The subjects included 14 normal subjects and 15 patients who underwent vagotomy plus drainage for more than one year. Taking milk, lactose and water emulsion 500ml as a test meal. In double sampling
