摘要
目的研究新生儿脐部细菌定植及感染的危险因素。方法采用目标性监测方法 ,研究新生儿脐部细菌定植及感染情况,并对14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例新生儿脐部有细菌定植327例,定植率为94.51%,脐部感染39例,感染率11.27%,主要为大肠埃希菌、金黄色葡萄球菌、其他肠道杆菌及耐药菌等,脐带结扎位置、脐带残端长度、脐带直径、脐带贴污染脐部是脐部感染的独立危险因素。结论新生儿脐部易发生细菌定植与感染,控制其危险因素,可预防感染的发生。
OBJECTIVE To study the bacterial colonization and the risk factors of neonatal umbilical infection.METHODS The bacterial colonization and neonatal umbilical infection were investigated by using the targeted surveillance method,and 14 related risk factors were conducted by the single analysis and multivariate unconditional Logistic regression analysis.RESULTS Among 346 neonates,there were 327 neonates with bacterial colonization,the colonization rate was 94.51%.There were 39 neonates with umbilical infection,and the umbilical infection rate was 11.27%,mainly due to Escherichia coli,Staphylococcus aureus,other enteric bacilli,drug-resistant bacteria and so on.The ligation position,the stump length,the diameter and the contamination of the umbilical cord were the independent risk factors for umbilical infection.CONCLUSION Newborn navel is prone to occur the bacterial colonization and infection.To control the risk factors can prevent the infection.
