早产儿胃液培养在早发性感染诊断中的价值

摘要

Objective To analyze the clinical value of gastric bacterial cultivation in the early diagnosis of bacterial infection in preterm infants.Methods 174 preterm with risk perinatal factors of infection in NICU of Chang’an Hospital from January 2013 to December 2014 were collected,they were given the gastric juice cultivation checking in 1 hour after birth before eat-ing,watering and giving medicine.According to the clinical symptoms and laboratory test results,they were divided into the infected group and non-infected group.Their Gastric cultivation inspection was compared and analyzed in two groups.Results The positive rate of bacterial culture of gastric fluid was 40.8% (71/174),and located in the top four is Escherichia coli 30.99% (22/71),coagulase-negative staphylococci 21.13%(15/71),Staphylococcus aureus 14.08%(10/71)and group B streptococcus 8.45% (6/71).There was relation between premature infants with bacterial culture positive and meconium stained amniotic fluid,maternal infection during pregnancy,premature rupture of membranes,but not with gestational hyper-tension,fever unrelated to the mother giving birth.Conclusion There was high positive rate of gastric juice bacterial culture with a significant correlation of early onset infection.%目的：分析早产儿胃液细菌培养在早发性感染诊断中的价值。方法对2013～2014年长安医院新生儿重症监护室（NICU）收治的174例早产儿行胃液细菌培养，根据临床症状及实验室检查结果将患儿分为感染组和非感染组，进行统计学分析。结果胃液细菌培养阳性率为40.8％（71／174），位于前四位的是大肠埃希氏菌30.99％（22／71）、凝固酶阴性葡萄球菌21.13％（15／71）、金黄色葡萄球菌14.08％（10／71）和 B 族链球菌8.45％（6／71），早产儿细菌培养阳性与羊水胎粪污染、母亲妊娠期感染、胎膜早破有关，与妊娠期高血压、母亲分娩时发热无关。结论胃液细菌培养阳性率高，与早发性感染有明显相关性。
