摘要
目的 探讨羊水过少的早期诊断及适当的产科处理与围产儿预后的关系。方法 对1 994～ 1 996年我院 1 0 1例羊水过少病例进行分析 ,并与正常分娩者进行对比。结果 我院羊水过少发生率为 2 .98% ,其胎儿宫内窘迫、胎儿宫内发育迟缓、新生儿窒息及吸入性肺炎发生率明显高于正常分娩组 ( P<0 .0 5)。产前以 B超羊水指数 ( AFI)≤ 8为诊断标准 ,其诊断率为 3 8.3 9% ,符合率为 95% ;另有2 2 .2 % AFI在 8.1～ 1 2 .0间 ,有 3 9.4 % AFI>1 2。妊娠合并症伴发羊水过少易发生在 3 7周后 ,正常妊娠在 4 0周后。结论 应重视对妊娠合并症在 3 7周后及正常妊娠在 4 0周后 B超对羊水的动态监测 ,但因其局限性 ,需结合临床胎心监护以提高对羊水过少的诊断率。在分娩方式上 ,羊水过少不是剖宫产的绝对手术指征 ,应结合有无高危因素、胎心监护情况及宫颈条件综合选择适当的分娩方式。阴道分娩中强调严密监护 ,控制产程 ,作好新生儿复苏。
Objective To assess the relationship between the early diagnosis and properly treatment of oligohydramnios and fetal outcome Methods A total of 101 cases of oligohydramnios from 1994 to 1996 were analyzed and compared with normal parturition Results The incidence of oligohydramnios was 2 98% The rate of fetal distress,IUGR,neonatal asphyxia and pneumonia in oligohydramnios group were statistically higher than in the control group respectively The B model ultrasound measured amniotic fluid index(AFI)≤8 was taken as the diagnostic standard for oligohydramnios With this standard,38 39% of patients were diagnosed with oligohydramnios,and the AFI between 8 1 to 12 0 were seen in 22 2%,AFI>12 in 39 4% Conclusions Oligohydramnios resulted from pregnant complications was usually happened after the 37th week of pregnancy,and in normal pregnant women usually after the 40th week of pregnancy
