对66例入院时病程未超过14夭,但总病程逾2周的感染性腹泻患儿与同期住院治疗的急性感染性腹泻患儿进行1:1配对病例对照研究。经条件Logistic回归模型分析,结果筛选出4个危险因素,即既往有腹泻史、粪便细菌培养检出条件致病菌、营养不良和中性粒细胞升高。提示:降低急性感染性腹泻的发病率、对急性腹泻治疗严格掌握抗生素应用指征、避免条件致病菌继发感染、及时治疗、纠正营养不良将会对降低迁延性腹泻发病率起重要作用。
A case-control study of 1: 1 matched pairs of children with infectious diarrhea in 66 children admitted to hospital who did not last longer than 14 days but had a history of more than 2 weeks and hospitalized patients with acute infectious diarrhea during the same period. Logistic regression model analysis, the results were screened four risk factors, namely, history of previous diarrhea, faecal bacteria detection of pathogenic bacteria, malnutrition and neutrophils increased. Tip: to reduce the incidence of acute infectious diarrhea, strict control of acute diarrhea indications for antibiotics, to prevent secondary infection of opportunistic pathogens, timely treatment, to correct malnutrition will play an important role in reducing the incidence of persistent diarrhea.
