产妇的分娩方式与羊水量的多少密切相关,目前各家测定羊水量的标准不尽相同。我们对1994年4月至6月在我院分娩的108例40周以上妊娠的孕妇,产前进行B超检查,测量羊水最大暗区。按照张首杰等提出的标准为依据,以羊水最大暗区≤2.0cm为羊水过少;2.0～3.0cm为羊水较少;≥3.0cm为正常,>8.0cm为羊水过多。将108例产妇的羊水量与分娩情况分析如下。 1 临床资料 1.1 本组108例产妇,不同孕周羊水量分布情况孕40～40w~(+6)者53例,羊水量较少的3例,羊水量正常的50例,孕41～41w~(+6)者27例,羊水较少的3例,羊水量正常的24例;妊娠超过42周者28例,羊水量较少的4例,羊水量正常的24例。 1.2 10例羊水量较少孕妇中,不同年龄分布情况,30岁以下,孕40～40w~(+6)者1例,超过42周者4例;30岁以上,孕40～40w~(+6)者2例,孕41～41w~(+6)者3例。 1.3 10例羊水量较少者,按胎次与产次分布情况 一胎一产4例;二胎一产2例;二胎二产以上的4例(41～41w~(+6)妊娠的3例,大于42w的1例)。
Maternal delivery and the amount of amniotic fluid is closely related to the current determination of the amount of amniotic fluid each different standards. In our hospital from April to June 1994, 108 cases of pregnant women over 40 weeks of pregnancy, prenatal B-ultrasound, the largest area of amniotic fluid was measured. According to Zhang et al. Proposed standards as the basis, the largest dark area amniotic fluid ≤ 2.0cm for oligohydramnios; 2.0 ~ 3.0cm for amniotic fluid less; ≥ 3.0cm for normal,> 8.0cm for polyhydramnios. 108 maternal amniotic fluid volume and childbirth situation is analyzed as follows. 1 Clinical data 1.1 108 cases of mothers in this group, different gestational weeks amniotic fluid distribution of pregnancy 40 ~ 40w ~ (+6) in 53 cases, 3 cases of amniotic fluid less, 50 cases of normal amniotic fluid, pregnancy 41 ~ 41w ~ (+6) in 27 cases, 3 cases of amniotic fluid less, 24 cases of normal amniotic fluid; pregnancy more than 42 weeks in 28 cases, 4 cases of amniotic fluid less, 24 cases of normal amniotic fluid. 1.2 10 cases of pregnant women with low amniotic fluid, the distribution of different age, 30 years of age, pregnancy 40 ~ 40w ~ (+6) in 1 case, more than 42 weeks in 4 cases; 30 years of age, pregnancy 40 ~ 40w ~ 6) in 2 cases, pregnant 41 ~ 41w ~ (+6) in 3 cases. 1.3 10 cases of oligohydramnios, according to the distribution of parity and delivery times in one case of 4 cases; 1 second birth in 2 cases; second child more than two births in 4 cases (41 ~ 41w ~ (+6) of pregnancy 3 cases, more than 42w in 1 case).
