Amniotic fluid samples from 95 internally monitored patients were examined to determine whether the appearance of polymorphonuclear leukocytes or bacteria could predict intrauterine infection. All patients delivered vaginally. More than one polymorphonuclear leukocyte per oil field were seen in specimens of 32% of patients; bacteria were seen in specimens of 52% of patients, and organisms were grown in 93% of specimens, yet, the overall maternal infection rate was only 6.3%. Moreover, infection developed in only 10% of patients with polymorphonuclear leukocytes in the fluid and 6% of patients with positive gram stain or cultures. For patients who deliver vaginally, the appearance of polymorphonuclear leukocytes or bacteria does not predict infection.
对95例进行内部监测的患者的羊水样本进行检查，以确定多形核白细胞或细菌的出现是否可预测宫内感染。所有患者均经阴道分娩。32%患者的样本中每个油镜视野可见一个以上的多形核白细胞；52%患者的样本中可见细菌，93%的样本中培养出微生物，但总体产妇感染率仅为6.3%。此外，羊水有多形核白细胞的患者中仅10%发生感染，革兰氏染色或培养阳性的患者中仅6%发生感染。对于经阴道分娩的患者，多形核白细胞或细菌的出现并不能预测感染。
