目的:探讨单纯性单脐动脉(SUA)胎儿的围产期结局以及分娩方式选择。方法:将68例在该院终止妊娠的单纯性SUA孕妇作为观察组,选择同期126例健康孕妇作为对照组,比较两组分娩方式、胎心监护以及胎儿围产期结局。结果:该院行超声检查的孕妇中SUA发生率为0.43%。观察组因胎儿窘迫直接行剖宫产的比例为42.42%,因胎儿窘迫、羊水污染等胎儿不良事件中转剖宫产的比例为75.00%,总剖宫产率为72.06%,与对照组比较差异均有统计学意义(P<0.05)。观察组胎心监护异常情况发生率显著高于对照组,差异有统计学意义(P<0.05)。观察组胎儿羊水Ⅱ度以上污染、小于胎龄儿的发生率均显著高于对照组,新生儿出生体重显著低于对照组,差异有统计学意义(P<0.05)。结论:单纯性SUA孕妇分娩时需严密观察产程及胎儿宫内情况,可以考虑适当放宽剖宫产指征。
Objective: To investigate the perinatal outcome of single umbilical artery (SUA) fetus and the choice of mode of delivery. Methods: A total of 68 healthy pregnant women who terminated pregnancy at the hospital were selected as observation group. 126 healthy pregnant women in the same period were selected as control group. The mode of delivery, the fetal heart rate monitoring and the perinatal outcome were compared between the two groups. Results: The incidence of SUA was 0.43% in pregnant women undergoing ultrasound examination. In the observation group, the rate of cesarean section directly due to fetal distress was 42.42%. The rate of cesarean section was 75.00% due to fetal distress and amniotic fluid contamination, and the total cesarean section rate was 72.06%, which was significantly lower than that of the control group All were statistically significant (P <0.05). The incidence of abnormal fetal heart rate monitoring group was significantly higher than the control group, the difference was statistically significant (P <0.05). Observation group of amniotic fluid more than degree of amniotic fluid pollution, the incidence of children younger than gestational age were significantly higher than the control group, newborn birth weight was significantly lower than the control group, the difference was statistically significant (P <0.05). Conclusion: Simple SUA pregnant women need to observe the labor process during labor and intrauterine fetal conditions, you can consider appropriate relaxation of cesarean indications.
