目的 探讨吸吮吞咽贯序功能训练对早产儿经口喂养能力及进程的影响。方法 选取2022年3月至2023年4月山东省某三级甲等医院入住新生儿重症监护病房（neonatal intensive care unit，NICU）的早产儿135例为研究对象，采用随机数字表法，将早产儿随机分为吸吮-吞咽组、吸吮组及对照组，每组各45例。吸吮-吞咽组早产儿贯序接受3 min非营养性吸吮和5 min吞咽功能训练；吸吮组早产儿接受3 min非营养性吸吮；对照组早产儿接受常规喂养方法。三组早产儿均接受NICU常规护理。结果 吸吮-吞咽组早产儿开始经口喂养第4、8、10天的每分钟摄入奶量及进食初5 min摄入奶量占医嘱奶量的百分比均高于对照组（均P＜0.05），第8天及第10天高于吸吮组（均P＜0.05）；3组早产儿经口喂养过渡时间差异具有统计学意义（P＜0.05），吸吮-吞咽组早产儿经口喂养过渡时间比对照组缩短近2.4 d。结论 吸吮吞咽贯序功能训练可改善早产儿经口喂养能力，缩短经口喂养过渡时间。

Objective To explore the effect of sequential function training of sucking and swallowing on the performance and progress of oral feeding among preterm infants.Methods 135 preterm infants admitted to the NICU in a tertiary hospital in Shangdong Province from March 2022 to April 2023 were selected as the research objects.A random number table method was used to divide them into the sucking-swallowing group,the sucking group and the control group with 45 infants in each group.The preterm infants in the sucking-swallowing group received 3 minutes of non-nutritive sucking and 5 minutes of swallowing exercise in a sequential manner;the preterm infants in the sucking group received 3 minutes of non-nutritive sucking;and the preterm infants in the control group received the routine feeding.All three groups of preterm infants received routine care in NICU.Results The feeding efficiency (milk intake per minute) and feeding proficiency (volume taken in 5 min/volume prescribed) of the preterm infants in the sucking-swallowing group on Day 4,8 and 10 were better than those in the control group (all P＜0.05),while the feeding efficiency and feeding proficiency on Day 8 and 10 were higher than those in the sucking group (all P＜0.05).There was statistically significant difference in the transition time of oral feeding among the three groups (P＜0.05),and the transition time for oral feeding of the sucking-swallowing group was nearly 2.4 days shorter than that in the control group.Conclusions Sequential function training of sucking and swallowing can improve the oral feeding ability and shorten the transition time of oral feeding of preterm infants.
