目的探讨延期妊娠合并羊水偏少的临床特点及分娩方式。方法 2013年1月—2014年12月煤炭总医院住院收治的延期妊娠合并羊水偏少患者60例为观察组,同期住院收治的456例延期妊娠羊水量正常者为对照组,比较二组患者的临床特点、分娩方式和母婴结局。结果延期妊娠合并羊水偏少易发生胎儿宫内窘迫、新生儿重度窒息,剖宫产率较高(P<0.05),但二组患者临产后阴道试产成功率差异无统计学意义(P>0.05),同时发现延期妊娠合并羊水偏少阴道分娩时潜伏期及活跃期时间相对较长(P<0.05)。结论延期妊娠合并羊水偏少易发生胎儿宫内窘迫,但并不是剖宫产指征。延期妊娠合并羊水偏少患者应常规行阴道试产并相对放宽试产时间。
Objective To investigate the clinical features and mode of delivery of delaying amniotic fluid during late pregnancy. Methods From January 2013 to December 2014, 60 cases of delayed pregnancy with oligohydramnios were admitted to the Coal General Hospital in our hospital. 456 cases of normal pregnant women with postnatal deferred amniotic fluid in the same period were selected as the control group. The patients in the two groups were compared Clinical characteristics, mode of delivery and maternal and infant outcomes. Results Delayed pregnancy combined with oligohydramnios prone to fetal distress, severe neonatal asphyxia, cesarean section rate was higher (P <0.05), but the two groups of patients with postpartum vaginal trial success rate was not statistically significant (P> 0.05). At the same time, it was found that the latent period and the active period of prolonged pregnancy combined with oligohydramnios vaginal delivery were relatively longer (P <0.05). Conclusion Delayed pregnancy with oligohydramnios prone to fetal distress, but not indications for cesarean section. Prolonged pregnancy combined oligohydramnios should be routine vaginal trial production and relatively relaxed pilot production time.
