目的:分析羊水少的足月妊娠孕妇阴道试产结果及围产儿结局。方法:以2009年1月～2010年12月就诊的210例孕产妇作为研究对象,应用羊水指数(AFI)法估测羊水量,并测定脐动脉收缩期最大血流速度(s)与舒张末期血流速度(D)比值(S/D),分析比较超声诊断羊水偏少100例及羊水过少10例(研究组)和羊水量正常100例的足月妊娠妇女(对照组)阴道试产后的分娩结局。结果:研究组中新生儿重度窒息13例,重度窒息发生率为11.8%;新生儿病死4例,新生儿病死率为3.6%;剖宫产59例,占53.6%;阴道分娩51例,占46.4%。对照组中新生儿重度窒息1例,重度窒息发生率为1.0%;剖宫产37例,占37.0%;无新生儿病死。两组间比较差异有统计学意义(P<0.05)。结论:羊水量少患者的新生儿死亡率和新生儿重度窒息发生率及剖宫产率均明显高于正常产妇。羊水量少对胎儿危害较多,孕妇如发现胎动异常或腹部不适应及时到医院检查,进行及时处理,减少不良围生期结局的发生。
OBJECTIVE: To analyze vaginal trial results and perinatal outcome in term pregnant women with less amniotic fluid. Methods: A total of 210 pregnant women were enrolled in this study from January 2009 to December 2010. Amniotic fluid index (AFI) was used to evaluate the amniotic fluid volume. The maximal systolic velocity (s) and end diastolic phase (D) ratio (S / D), comparative analysis of 100 cases of oligohydramnios diagnosed by ultrasound and 10 cases of oligohydramnios (study group) and 100 cases of normal amniotic fluid of pregnant women (control group) after vaginal delivery The delivery end. Results: Thirteen cases of severe asphyxia and 11.8% of severe asphyxia were found in the study group, 4 cases of neonatal death, neonatal mortality was 3.6%, 59 cases of cesarean section (53.6%), vaginal delivery in 51 cases 46.4%. One case of neonatal severe asphyxia in control group, the incidence of severe asphyxia was 1.0%; 37 cases of cesarean section, accounting for 37.0%; no neonatal death. The difference between the two groups was statistically significant (P <0.05). Conclusions: Neonatal mortality, neonatal severe asphyxia and cesarean section rate in patients with low amniotic fluid volume are significantly higher than those in normal maternal. Less amniotic fluid damage to the fetus more, pregnant women found abnormal fetal movement or abdominal discomfort in a timely manner to the hospital for timely treatment to reduce the incidence of adverse perinatal outcome.
