目的分析足月妊娠妇女超声检查提示羊水偏少时,阴道试产对围生期结局的影响。方法2004年1月至2005年12月应用羊水指数(AFI)法估测羊水量,并测定脐动脉收缩期最大血流速度(S)和舒张末期血流速度(D)比值(S/D值)及24h尿雌三醇与肌酐比值,分析比较本溪市中心医院妇产科198例超声诊断羊水偏少者(观察组)和200例羊水量正常的足月妊娠妇女(对照组)阴道试产后的分娩结局。结果两组新生儿重度窒息发生率和新产儿病死率差异无显著性意义(P>0.05),观察组急诊剖宫产率明显升高(P<0.05)。结论超声诊断羊水偏少的足月妊娠妇女,在严密监护下可行阴道试产。
Objective To analyze the effect of vaginal trial production on perinatal outcome when ultrasound examination of full-term pregnant women indicates that oligohydramnios is less. Methods The amniotic fluid index (AFI) method was used to estimate amniotic fluid volume from January 2004 to December 2005 and the ratio of S / D (S / D) to systolic blood flow (S) and end diastolic velocity ) And 24h urinary estriol to creatinine ratio were compared between the 198 patients with benign gynecologic disease in 198 patients with benign and low amniotic fluid in observation group and 200 pregnant women with normal amniotic fluid volume (control group) The delivery end. Results There was no significant difference between neonates with severe asphyxia and neonatal mortality in the two groups (P> 0.05). Cesarean section rate in the emergency group was significantly higher (P <0.05). Conclusions Ultrasound diagnosis of less-term amniotic fluid in full-term pregnant women, feasible vaginal trial under close supervision.
