大便pH值与小儿急性腹泻病因关系探讨

测定急性腹泻病儿大便pH值,探讨与小儿急性腹泻病因关系。以精密试纸对细菌感染性腹泻病(Ia组)、急性非细菌感染性腹泻(Ib组)、急性非感染性腹泻(Ⅱ组)和非腹泻病儿(Ⅲ组)大便pH测定,对急性细菌感染性腹泻病儿大便连续监测。结果3年中测定了846例病儿大便,其中76例连续测定;Ia组大便pH8.0±1.06,Ib组5.79±0.51,Ⅱ组5.69±0.4,Ⅲ组5.92±0.46.Ia组与其他组差异明显(U=2.18,P<0.05),Ib组与Ⅱ、Ⅲ组间无显著差异(U=0.15,P>0.05);各种病原茵致泻大便pH值无差异(x~2=2.52,P>0.05)。Ia组恢复期大便pH值随着腹泻次数和大便中白细胞数减少以及细菌培养转阴而下降(x~2=113.38,P<0.01)。结果表明,大便pH值测定可作为小儿急性腹泻病因的简单、快速、价廉的初步诊断及指导应用抗菌药的重要参考资料。

Study of Relationship Between StoolpH and Acute Diarrhea Children

To explore the relationship between stool pH and acute diarrhea in children by measuring stool pH. Prospective using test - papers to measure stool pH in children was carried out. The stool would not be mixed by urine or water. The method included to measure the stool of children with acute bacterial infectious diarrhea (group Ⅰ)and acute noninfectious diarrhea (group Ⅱ)and non - diarrhea (group Ⅱ). It was continuous to measure the stool of children with acute bacterial infectious diarrhea. There were 846 cases children to be measured and 76 cases were continuous. The pH of group I was 8. 0±1. 06,group Ⅱ 5. 79 ± 0. 51,group Ⅱ was 5. 69 ± 0. 4 Group I was different from others( u =2. 18, P <0. 05). There were no difference in each bacterial types (x2 =2.52, P >0. 05). The stool pH was down during recovery in their health( x2 = 113. 38, P <0. 01). The measuring stool pH is valuable to diagnose and to treat acute diarrhea in children. The method is handy and quick and cheap. It could be a laboratory data of diagnosis in acute diarrhea in children.
