We investigated the effect of the temperature of a liquid meal on intragastric temperature, gastric acid secretion, gastrin release, and gastric emptying in normal human subjects. Coffee (360 mL) was infused into the stomach through a nasogastric tube at 58 (steaming hot), 37, or 4 degrees C (ice cold). Intragastric temperature, measured by an intragastric temperature sensor attached to the nasogastric tube, returned to body temperature 16.7 +/- 2.7 min after the hot meal and 23.8 +/- 1.1 min after the cold meal. Gastric acid secretion increased after hot, warm, and cold coffee but the initial temperature of the meal had no effect on gastric acid secretion. The temperature of the meal also had no effect on serum gastrin concentrations, which increased significantly after all the meals. Gastric emptying of hot, warm, or cold coffee meals was similar. These findings indicate that over a wide temperature range, the temperature of a liquid meal has little effect on gastric function in humans.
我们研究了流食温度对正常人体胃内温度、胃酸分泌、胃泌素释放及胃排空的影响。通过鼻胃管将360毫升咖啡分别以58℃（滚烫）、37℃或4℃（冰冷）的温度注入胃内。通过连接在鼻胃管上的胃内温度传感器测量发现，热饮后胃内温度在16.7±2.7分钟恢复至体温，冷饮后则在23.8±1.1分钟恢复至体温。热咖啡、温咖啡和冷咖啡均会使胃酸分泌增加，但流食的初始温度对胃酸分泌并无影响。流食温度对血清胃泌素浓度也无影响，所有餐食后血清胃泌素浓度均显著升高。热咖啡、温咖啡或冷咖啡餐食的胃排空情况相似。这些研究结果表明，在较宽的温度范围内，流食温度对人体胃功能影响甚微。
