摘要目的：探讨短期去乳糖奶粉喂养方法对新生儿腹泻的效果。方法选取2013年3月—2014年2月腹泻患儿140例，按随机数字表法随机分为观察组和对照组各70例，观察组采用短期去乳糖奶粉喂养，对照组采用长期去乳糖奶粉喂养。比较两组患儿治疗效果、胃肠道症状、体质量增长与喂养耐受情况。结果观察组患儿痊愈51例，有效17例，无效2例；对照组痊愈47例，有效20例，无效3例，差异无统计学意义（Z＝0．758，P＝0．366）。观察组患儿平均体质量增长（34．30±7．35）g／（kg? d），平均摄入奶量（105．37±24．02）ml／（kg? d），优于对照组的（24．29±8．06）g／（kg? d），（97．21±21．66）ml／（kg? d），差异有统计学意义（t值分别为2．809，3．161；P＜0．05）。观察组排便次数、呕吐、腹胀、胃潴留发生例数均少于对照组，差异有统计学意义（P＜0．05）。结论腹泻新生儿采取短期去乳糖奶粉喂养方式既符合婴幼儿的生长发育特点，又可以维持其免疫功能的平衡，且经济实惠，值得在临床推广。

abstractsObjective To explore the effect of short term non-lactose milk powder feeding for neonatal diarrhea.Methods Totals of 140 cases of neonatal diarrhea who were selected from March 2013 to February 2014 were randomly divided into observation group and control group .The observation group adopted short term non-lactose milk powder feeding , while the control group accepted long term non-lactose milk powder feeding . The effect of treatment , gastrointestinal symptom , average weight growth and milk powder tolerance were compared.Results In the observation group, the recovery, effective and ineffective neonatus were fifty one cases, seventeen cases and two cases respectively , while there were forty seven cases recovered , twenty nine effective cases and three ineffective cases in the control group .There were no statistical significance ( Z =0.758,P=0.366).The observation group had better results than the control group on average weight growth [(34.30 ±7.35) g/(kg? d) vs (24.29 ±8.06) g/(kg? d)] and milk powder intake [(105.37 ± 24.02)ml/(kg? d) vs (97.21 ±21.66)ml/(kg? d)], and the differences were statistically significant (t=2.809,3.161, respectively;P <0.05).In the observation group, the frequency of defecation, vomiting, ventosity and gastric retention were less than those of the control group (P<0.05).Conclusions The short term feeding of lactose free milk powder is not only suitable for infant ’ s growth and immune system improvement , but also economical and valuable for clinical application widely .
