目的观察无乳糖奶粉治疗继发性乳糖酶缺乏的疗效。方法 2010年10月至2011年1月在我院住院治疗的100例轮状病毒性肠炎患儿随机分为试验组和对照组,每组50例,大便中RV抗原检测均阳性,均采用醋酸铅加氢氧化氨法检测粪便中乳糖、pH值。粪便中乳糖大于或等于++,pH值小于5.5为乳糖不耐受。对照组予补液及口服蒙脱石散、微生态制剂等常规治疗。试验组患儿在常规治疗的基础上,加用无乳糖奶粉辅助治疗。观察临床疗效,并对结果进行统计学分析。结果试验组在腹泻持续时间、大便次数及粪乳糖转阴时间均明显优于对照组,两组比较差异具有统计学意义(P<0.05)。
Objective To observe the efficacy of lactose-free milk powder in the treatment of secondary lactase deficiency. Methods From October 2010 to January 2011, 100 children with rotavirus enteritis who were hospitalized in our hospital were randomly divided into test group and control group, with 50 cases in each group. RV antigen in stool was positive, and lead acetate Ammonia hydroxide method to detect lactose in the feces, pH value. Lactose in faeces is greater than or equal to ++, pH less than 5.5 is lactose intolerance. Control group to rehydration and oral montmorillonite powder, probiotics and other conventional treatment. The experimental group of children on the basis of conventional treatment, plus lactose-free milk adjuvant therapy. Observed the clinical curative effect, and carried on the statistical analysis to the result. Results The duration of diarrhea, the stool frequency and the time of defecation were significantly higher in the experimental group than those in the control group.
