临产孕妇的宫颈管细菌学检查

Bacteriological Examination for Cervical Canal of Pregnancy in Active Stage

50例临产孕妇子宫颈管细菌培养34例,需氧菌厌氧菌阳性分别为9例和6例,羊水培养19例,需氧菌厌氧菌阳性分别为5例和8例,破膜者宫颈管内分泌物或宫颈内羊水菌培养阳性率明显高于未破膜组(P<0.05)。随着宫缩的进展,宫口逐渐开大,细菌培养阳性率有上升的趋势,故避免胎膜早破,加强临产时监护、管理与治疗,减少产程延长或停滞,是降低孕产妇感染率的重要手段。

Bacteriological examination results of 50 pregnant cervical canals in active stage were reported. Among 34 cases of bacterial culture of the cervical canals, positive rate of aerobe was 9 cases(26.5%),while positive rate of anaerobe 6 cases(17.6%).19 cases of amniotic fluid culture was taken. 5 cases of aerobe culture were positive, 8 cases of anaerobe culture positive, 26.3% and 42.1% respectively. As to the positive rate of bacterial culture of cervical canal and amniotic fluid in the uterine cavity, the, the group with the rupture of membaranes was significantly higher than non-rupture group (P<0.05). In the process of dilatation of the cervix, the positive rate of bacterial culture tends to go up. Therefore, avoiding premature rupture of membaranes, strongening the monitor, management and treatment for pregnancy in active stage, reducing delay in labour or stasis of delivery are the most important for turning down maternal infective morbidity.
