目的 :探讨粪还原糖含量和pH值检测在小儿轮状病毒感染诊治中的临床意义。方法 :以 32例轮状病毒性肠炎患儿为观察组 ,进行粪还原糖含量及pH值检测 ,并对其中 1 0例进行治疗后检测对比 ;以 2 0例诊为症状性腹泻患儿为对照组 ,并对检测结果作对照比较。粪还原糖测定采用改良斑氏试剂法 ,粪pH用pH试纸法测定。结果 :观察组粪还原糖测定阳性 2 8例 (占 87.5 % ) ,对照组阳性 3例 (占 1 5 .0 % ) ,两组比较差异有显著性 (P <0 .0 0 5) ;对阳性病例治疗后复查 1 0例 ,阴转 9例。粪pH检测结果 :观察组与对照组的比较差异有显著性 (P <0 .0 0 1 ) ;观察组中的 1 0例治疗前后粪pH值比较差异亦有显著性 (P <0 .0 0 5)。结论 :轮状病毒感染患儿的粪还原糖能间接反映患儿乳糖酶的损害程度 ,同时测定粪还原糖和粪便pH可提高轮状病毒感染后继发糖吸收不良的诊断率
Objective: To investigate the clinical significance of detection of fecal reducing sugar and pH value in the diagnosis and treatment of pediatric rotavirus infection. Methods: Thirty-two children with rotavirus enteritis were selected as the observation group, the fecal reducing sugar content and pH value were detected, and 10 cases of them were detected for comparison. In 20 children with symptomatic diarrhea Control group, and compare the test results for comparison. Determination of fecal reducing sugars using the modified method of the spot, fecal pH using pH test paper method. Results: In the observation group, 28 cases (87.5%) were positive for fecal reducing sugar and 3 cases (15.0%) in the control group, with significant difference between the two groups (P <0.05) Positive cases after treatment review of 10 cases, 9 cases of negative conversion. Fecal pH test results: the difference between the observation group and the control group was significant (P <0. 01); the observation group of 10 cases of manure pH value before and after treatment were also significant differences (P <0 .0 0 5). CONCLUSIONS: Fecal reducing sugars in children with rotavirus infection indirectly reflect the degree of lactase damage in children. Simultaneous determination of fecal reducing sugars and faecal pH may improve the diagnostic rate of secondary sugars malabsorption after rotavirus infection
