围产期B族链球菌感染筛查及防治在基层医院中的推广应用

Application and promotion of screening and prevention of group B streptococcal infection during perinatal period in primary hospitals

目的探讨基层医院实施围产期B族链球菌感染筛查及防治的价值。方法回顾性分析我院2019年7月至2020年7月纳入的4220例围产期孕妇作为研究对象,收集并整理其齐全资料,并在我院接受阴道与直肠的B族链球菌感染筛查,经B族链球菌感染筛查结果,将其中507例阳性者作为阳性组,另3713例阴性者作为阴性组,分析围产期B族链球菌感染筛查及防治运用于基层医院中的价值。结果本院所有研究对象均接受B族链球菌感染筛查,结果发现阳性者507例,阳性率为12.01%;阴性者3713例,阴性率为87.99%。两组在剖宫产、产后出血、产褥感染、新生儿窒息、胎儿窘迫上比较,差异无统计学意义(P>0.05);但阳性组的绒毛膜羊膜炎、羊水污染、胎膜早破、新生儿感染发生率均高于阴性组(P<0.05)。结论基层医院中实施围产期B族链球菌感染筛查具有重要意义,应受到医疗界重点关注,经过筛查后尽早给予有效干预,从而避免不良妊娠结局产生,保障母婴安全。

Objective To explore the value of screening and prevention of group B streptococcal infection during perinatal period in primary hospitals.Methods Based on the retrospective analysis method,4220 perinatal pregnant women who were admitted to our hospital from July 2019 to July 2020 were selected as experimental subjects.The complete information was collected.They were given screening for group B streptococcal infection of vagina and rectum in our hospital.Based on the results of screening for Streptococcus infection,507 positive cases were selected as the positive group,and the other 3713 negative cases were selected as the negative group.The value of screening and prevention of group B streptococcus infection during perinatal period in primary hospitals was analyzed.Results All experimental subjects in our hospital were screened for group B streptococcus infection.As a result,507 cases were found to be positive,with a positive rate of 12.01%;there were 3713 negative cases,with the negative rate of 87.99%.There were no statistically significant difference in terms of Cesarean section,postpartum hemorrhage,puerperal infection,neonatal asphyxia,and fetal distress(P>0.05).However,the incidence rate of chorioamnionitis,amniotic fluid contamination,premature rupture of membranes,and neonatal infection in the positive group were higher than those in the negative group(P<0.05).Conclusion The implementation of screening of group B streptococcal infection during perinatal period in primary hospitals is of great significance and the medical community should pay close attention to it.After screening,effective intervention should be given as soon as possible to avoid adverse pregnancy outcomes and ensure the safety of mothers and infants.
