ABSTRACT
OBJECTIVES@#To study the effect of intrapartum antibiotic prophylaxis (IAP) of group B streptococcus (GBS) infection on the incidence and bacteriological profile of early-onset neonatal sepsis (EONS).@*METHODS@#A retrospective analysis was performed on the medical data of 494 pregnant women with positive GBS screening results and 526 neonates born by these women. According to whether the pregnant woman received IAP, the neonates were divided into two groups IAP (n=304) and control (n=222). The two groups were compared in terms of clinical indices, incidence rate of EONS, and distribution of pathogenic bacteria in blood culture.@*RESULTS@#Compared with the control group, the IAP group had a significantly lower proportion of children with abnormal clinical manifestations (P<0.001) and a significantly lower incidence rate of EONS (P=0.022). In the IAP group, Escherichia coli (2.3%) was the most common type of pathogenic bacteria in blood culture of the neonates with EONS, while GBS (3.2%) was the most common type of pathogenic bacteria in the control group. The IAP group had a significantly higher detection rate of ampicillin-resistant Escherichia coli than the control group (P=0.029).@*CONCLUSIONS@#Although IAP can significantly reduce the incidence rate of EONS in neonates born to pregnant women with positive GBS screening results, the infection rate of ampicillin-resistant Escherichia coli may increase after IAP treatment. Therefore, it is needed to enhance the monitoring of blood culture results of neonates with EONS and timely adjust treatment plan according to drug susceptibility test results.
