目的 :探讨不含乳糖奶粉治疗迁延性腹泻的疗效。方法 :将 81例迁延性腹泻患儿分为两组 ,治疗组给予不含乳糖奶粉喂养 ,对照组继续母乳或配方奶粉喂养。结果 :治疗组腹泻消失时间明显短于对照组 ( χ2 =2 3 68,P <0 0 1)。结论 :迁延性腹泻患儿常存在继发性乳糖不耐受 ,所以对迁延性腹泻患儿暂停含乳糖食物 ,给予无乳糖奶粉喂养 ,可减轻临床症状 ,缩短腹泻时间。
Objective: To investigate the efficacy of lactose-free milk powder in the treatment of persistent diarrhea. Methods: 81 cases of persistent diarrhea were divided into two groups, the treatment group was fed lactose-free milk, the control group continued breast-feeding or formula feeding. Results: The disappearance time of diarrhea in treatment group was significantly shorter than that in control group (χ2 = 2368, P <0.01). CONCLUSIONS: Secondary lactose intolerance often exists in children with persistent diarrhea. Therefore, suspending lactose-containing foods and lactose-free milk powder in children with persistent diarrhea may reduce the clinical symptoms and shorten the diarrhea time.
