Objective To investigate the influence of trace feeding combined with non-nutritive sucking on feeding in-tolerance in preterm infant. Methods 90 preterm infants with feeding intolerance were randomly divided into the two groups,45 patients of the treatment group of were given trace feeding in early stage combined with non-nutritive suck-ing,while 45 patients of the control group were conventional feeding. Results The time of recovering to the birth weight and being up to the full amount of enteral nutrition in the treatment group was obviously shorter than that in the control group, the total bilirubin level in the treatment group was higher than that in the control group,albumin level in the treatment group was higher than that of the control group respectively (P<0.05).The incidence rate of gastric retention>30%of milk amount,abdominal distension,vomiting>3 times in the treatment group was obviously lower than that in the control group,and the feeding intolerance rate in the treatment group was higher than that in the control group (P<0.01). Conclusion Trace feeding combined with non-nutritive sucking applied in preterm infant can improve the tolerance of enteral feeding,improve nutrition,promote growth and development of preterm infant.It is worthy of clinical promotion and application.%目的：探讨微量喂养联合非营养吮吸对早产儿喂养不耐受的影响。方法将90例喂养不耐受的早产儿随机分为两组，治疗组45例给予早期微量喂养与非营养性吸吮；对照组45例给予常规喂养。结果治疗组的恢复至出生体质量时间、达全量肠内营养时间均明显短于对照组，总胆红素水平低于对照组，清蛋白水平高于对照组（P<0.05）；治疗组的胃潴留跃30%奶量、腹胀、呕吐跃3次的发生率均明显低于对照组，治疗组的喂养不耐受率低于对照组（P<0.01）。结论早期微量喂养联合非营养性吸吮用于早产儿能提高其胃肠喂养的耐受性，改善其营养状况，促进其生长发育，值得临床推广应用。
