The diarrhea sometimes associated with nasogastric tube feeding has been attributed to the cool temperature of the formula. To test the effect of temperature variations of liquid feedings on gastric motility, a strain gauge and feeding tube were surgically implanted in the stomachs of rhesus monkeys. With the monkeys awake and restrained, the investigators infused constant volumes of water and liquid diet formula at varying temperatures and recorded gastric motility. The temperature of the liquid did not significantly alter gastric motility or gastric emptying, suggesting that the temperature of administration of the tube feeding is not a cause of diarrhea.
有时与鼻胃管喂食相关的腹泻被认为是由于配方奶温度较低。为了测试液体喂食温度变化对胃动力的影响，将应变片和喂食管通过手术植入恒河猴的胃中。在猴子清醒并受到约束的情况下，研究人员以不同温度注入恒定体积的水和流质饮食配方，并记录胃动力。液体温度并未显著改变胃动力或胃排空，这表明管饲的给药温度不是腹泻的原因。
