Abstract: Objective To explore the effectiveness of swallowing function training on oral feeding performances in premature infants. Methods According to the simple randomized grouping method,140 cases of premature infants were divided into 2 groups,65 cases in the loss of final intervention group,and 69 cases in control group,the intervention group received swallowing function training every day,until stopping tube feeding.The control group received NICU routine nursing care,including intermittent feeding,support position,etc.The postmenstrual age(PMA)of the two groups were recorded when started oral feeding and completely oral feeding.Moreover,feed efficiency was observed at the two time points,weight was recorded every day,weight growth rate was calculated. Results The PMA and weight of the intervention group which through oral feeding completely were significantly less than those of the control group,the difference was statistically significant (P<0.05).Compared the transition time of the two groups from the initiation of oral feeding to full oral feeding,the intervention group's use time was shorter than that of the control group obviously,the difference was statistically significant (P<0.05).The feeding efficiency in the intervention group was significantly higher than that of the control group (P<0.05).The difference was statistically significant (P<0.05).There were no significant differences in the length of hospital stay and weight gain rate between the two groups. Conclusion Early swallowing function training is beneficial for the oral feeding in preterm infant.

摘要： 目的 研究吞咽功能训练对早产儿经口喂养表现的影响,为NICU早产儿喂养的改善提供临床依据。方法 按照简单随机化分组的方法,将140例早产儿随机分为2组,流失后最终干预组65例,对照组69例,干预组每天接受1次吞咽功能训练,直至其停止管饲喂养。对照组接受NICU常规护理,包括间歇喂养、体位支持等。 记录两组达到开始经口喂养和完全经口喂养时的纠正胎龄,并在这两个时间点观察喂养效率,记录每天体重,计算体重增长速度。结果 干预组完全经口喂养时的纠正胎龄和体重明显小于对照组,差异均有统计学意义(P<0.05)。 从开始经口喂养到完全经口喂养的过渡时间两组比较,干预组明显短于对照组,差异有统计学意义(P<0.05)。 干预组开始经口喂养时的喂养效率明显高于对照组,差异有统计学意义(P<0.05)。 两组在体重增长速度、住院时间等方面没有明显差别。结论 早期进行吞咽功能训练有助于早产儿经口喂养状况的改善。
