Gastric emptying of newborn infants is a procedure performed to prevent aspiration of gastric contents. The present investigation was conducted to study the effects of gastric suction on circulatory and behavioural parameters in 21 healthy newborn children (11 cases, 10 controls). A small elevation in mean arterial blood pressure was observed during gastric suction. The incidence of retching was also increased. In all children spontaneous sucking and rooting movements, as well as state of sleep and wakefulness were recorded. In the control group spontaneous sucking and rooting movements started occur 15 min after birth and reached a maximum at 45 and 60 min, respectively. The first hand to mouth movement was observed after a mean of 34 min and the infants found the nipple and started to suckle at about 55 min. This sequence of prefeeding behaviour was disrupted in children who had undergone gastric suction. The physiological side-effects induced by gastric suction are minor, but it seemed to be unpleasant for the child and no clear advantages are gained by the procedure.
新生儿胃排空是一项用于防止胃内容物误吸的操作。本研究旨在探讨胃抽吸对21名健康新生儿（11例为实验组，10例为对照组）循环和行为参数的影响。在胃抽吸过程中观察到平均动脉血压有小幅升高。干呕的发生率也有所增加。记录了所有儿童的自发吸吮和觅食动作，以及睡眠和觉醒状态。在对照组中，自发吸吮和觅食动作在出生后15分钟开始出现，分别在45分钟和60分钟达到峰值。平均34分钟后观察到首次手到口的动作，婴儿在大约55分钟找到乳头并开始吸吮。这种喂食前行为的顺序在接受胃抽吸的儿童中被打乱。胃抽吸引起的生理副作用较小，但对儿童来说似乎不太舒服，且该操作没有明显优势。
