目的分析妊娠期女性阴道微生态状况。方法妊娠妇女91例分为早孕期(A组,33例),中孕期(B组,30例)和晚孕期(C组,28例)3组,以阴道pH值、阴道脱落细胞致密核指数(KI)、阴道菌群三项指标对阴道清洁度和阴道微生态进行评价。结果 A、B、C三组KI分别为(89.94±3.29)%、(89.30±2.90)%、(89.93±2.62)%;乳酸杆菌优势率为87.88%、83.33%、75.00%;阴道pH值为(3.80±0.39)、(3.78±0.31)、(3.78±0.34);三项指标组间差异均无统计学意义。91例妊娠期妇女阴道pH值与KI呈负相关(P<0.01)。结论不同妊娠期妇女阴道KI、乳酸杆菌优势率、阴道pH值相似;pH值减低,KI及乳酸杆菌优势率增高。
Objective To analyze the status of vaginal microecology in pregnant women. Methods 91 pregnant women were divided into three groups: early pregnancy (group A, 33 cases), middle pregnancy (group B, 30 cases) and late pregnancy (group C, 28 cases). Vaginal pH, (KI), vaginal flora three indicators of vaginal cleanliness and vaginal microflora evaluation. Results The KI of groups A, B and C were (89.94 ± 3.29)%, (89.30 ± 2.90)% and (89.93 ± 2.62)%, respectively. The dominant strains of Lactobacillus were 87.88%, 83.33% and 75.00% (3.80 ± 0.39), (3.78 ± 0.31) and (3.78 ± 0.34), respectively. There was no significant difference among the three indexes. The vaginal pH value of 91 pregnant women was negatively correlated with KI (P <0.01). Conclusions The prevalence rates of vaginal KI, lactobacillus and vaginal pH in women of different gestations are similar. The pH value is decreased, and the predominance rates of KI and Lactobacillus are increased.
