产前B族链球菌筛查对新生儿影响

目的 探讨孕期进行B族链球菌(GBS)筛查并进行治疗对新生儿GBS发病率及临床表现的影响。方法 选取孕晚期经过常规筛查GBS阳性结果并给予抗菌药物治疗,分娩时诊断为胎膜早破的47例孕妇作为实验组;选取孕晚期未经过常规GBS筛查和治疗,分娩时诊断为胎膜早破的73例孕妇作为对照组,观察2组新生儿的临床表现,并收集咽拭子标本,采用PCR方法检测GBS。结果 实验组无新生儿发生GBS感染、呼吸困难、青紫、发热,对照组有7例GBS感染,2例呼吸困难,2例青紫,4例发热。2组新生儿各指标比较,差异均有统计学意义(P0.05)。结论 孕期行GBS筛查与治疗,可有效降低新生儿GBS感染的发病率。

The influence of group B streptococcus screening to newborns

Objective To explore the influence of group B Streptococcus screening during pregnancy and the incidence of the ear‐ly‐onset GBS disease for newborns .Methods Totally 47 cases of pregnant women with premature rupture of membranes (PROM ) , which were GBS positive and accepted antibiotic treatment ,who were chosen as the experimental group .While 73 cases of pregnant women with premature rupture of membranes (PROM) ,which were not accept GBS screening and antibiotic treatment ,were chosen as control group .The neonatal clinical manifestations were observed .The swab specimens were collected from throat and detected of GBS by using PCR method .Results The experimental group showed no occurrence of neonatal group B streptococcal infection , dyspnea ,cyanosis and fever .Totally 7 cases of the control group had group B Streptococcus infection .Totally 2 cases had dyspnea and 2 cases had cyanosis .Totally 4 cases had fever .The neonatal research indicators of these two groups were statistically signifi‐cant differences (P<0 .05) .Conclusion The group B Streptococcus screening during pregnancy would effectively reduce the inci‐dence of neonatal infection of group B Streptococcus .
