摘要
目的:探讨新生儿脐部感染的危险因素及进行病原学分析,为制定控制新生儿感染措施提供理论依据。方法:采用目标性监测方法,研究新生儿脐部感染情况及病原学,并对脐带结扎位置、脐带残端长度、脐带直径、脱脐时间、脐带贴卫生、手卫生等12项相关危险因素进行单因素和多因素非条件Logistic回归分析。结果:346例新生儿脐部感染39例,感染率11.27%,主要为大肠埃希氏菌、金黄色葡萄球菌、其他肠道杆菌及耐药菌。脐带结扎位置、脐带残端长度、脐带直径、脐带脱落时间、脐带贴卫生、手卫生对脐部感染有影响(P<0.05)。脐带结扎位置、脐带残端长度、脐带直径、脐带贴卫生是脐部感染的独立危险因素。结论:新生儿易发生脐部大肠埃希氏菌、金黄色葡萄球菌感染,脐带结扎位置距脐根<0.5 cm、脐带残端<0.5 cm、保持脐带贴卫生等可预防脐部感染。
Objective：To explore the risk factors of umbilical infection of neonates,carry out aetiological analysis,provide a theoretical basis for making measures to control neonatal infection. Methods：A objective monitoring method was used in the study to research the umbilical infection status of neonates and aetiology,12 related risk factors including the position of umbilical cord ligation,the length of umbilical remnant,the off time of umbilical cord,hygiene of umbilical paste and hygiene of hands,and so on,were summarized for univariate non-conditional Logistic regression analysis and multivariate non-conditional Logistic regression analysis. Results：Among 346 neonates,39 neonates were found with umbilical infection,the infection rate was 11.27%,the major pathogens were Escherichia coli,Staphylococcus aureus,other enteric bacilli and drug-resistance bacteria.The position of umbilical cord ligation,the length of umbilical remnant,the off time of umbilical cord,hygiene of umbilical paste and hygiene of hands had impact on umbilical infection（P〈0.05）.The position of umbilical cord ligation,the length of umbilical remnant,the diameter of umbilical cord and hygiene of umbilical paste were the independent risk factors of umbilical infection. Conclusion：Neonates are prone to umbilical Escherichia coli and Staphylococcus aureus infection,the distance of position of umbilical cord ligation and the root of umbilical cord less than 0.5 cm,the length of umbilical remnant less than 0.5 cm and maintaining hygiene of umbilical paste can prevent umbilical infection.
