目的探讨妊娠晚期NST无反应型孕妇胎盘功能与胎儿窘迫的相关性。方法选择孕34周后因NST无反应入院孕妇100例,当日复查NST转为反应型为A组25例;对仍无反应者行OCT试验,阴性者为B组20例;阳性者为C组55例。并设同期NST有反应者50例为对照D组。四组孕妇均测血-βHCG、E3并行B超及羊膜镜检查。分析各组胎心监护、-βHCG、E3与胎儿窘迫的相关性。结果 C组孕妇-βHCG值较其他各组升高、E3值降低,胎儿窘迫发生率明显升高,差异有统计学意义。结论对于孕晚期NST无反应者应慎重处理,密切监测胎盘功能,判断胎儿宫内状况,提高产科质量,降低剖宫产率。
Objective To investigate the relationship between placental function and fetal distress in non-responsive pregnant women with NST during late pregnancy. Methods 100 pregnant women were selected as nonresponders to NST after 34 weeks of gestation. On the day of retest, NST was changed to 25 cases in group A, OCT was performed in those with no response, 20 cases in group B and 20 cases in group B 55 cases. And set the same period NST responders were 50 cases as control D group. Four groups of pregnant women were measured blood-βHCG, E3 parallel B-mode and amniocentesis. Analysis of each group fetal heart rate monitoring, -HCHC, E3 and fetal distress correlation. Results Compared with other groups, the value of βHCG in pregnant women in group C increased, the E3 decreased, and the incidence of fetal distress increased significantly. The difference was statistically significant. Conclusions Patients who do not respond to NST in the third trimester should be treated with caution. The function of the placenta should be closely monitored to determine the status of the fetus, improve the obstetric quality and reduce the rate of cesarean section.
