地震后孕妇焦虑对胎儿生理状态影响超声研究

Effect of pregnant anxiety on fetal physiological states after earthquake

目的:采用超声技术探讨地震后伴有焦虑孕妇胎儿的生理指标变化以及焦虑和胎儿风险的相关性。方法:根据焦虑自评量表(SAS)测试评分结果,分为正常组、轻度焦虑组、中度焦虑组、重度焦虑组。分别检测胎儿心率(HR)、脐带血流阻力指数(RI)、脐动脉收缩期最大血速度/舒张末期血流速度(S/D)等指标。结果:地震灾区孕妇多患有轻、中度焦虑,焦虑组各指标与正常组比较差异有显著性(P<0.05或P<0.01)。结论:孕妇焦虑会影响胎儿的生理状态,超声检测相关指标可为临床孕妇和胎儿围产期保健提供可靠的依据。

Objective： To investigate the fetal physiological changes and to explore the relationship between anxiety of pregnant women and the risk of fetus after earthquake by using ultrasonic technology. Method： According to the scores of self-rating anxiety scale （ SAS）, the pregnant women were divided into four groups ： normal group, mild anxiety group, moderate anxiety group and severe anxiety group. Using the method of ultrasound scan,all the fetus were detected with heart rate（ HR）, resistance index of umbilical cord blood（ RI ） and systolic/diastolic ratio（S/D）. Results： Majority of pregnant women who suffered earthquake developed mild or moderate anxiety. There were significant differences in HR, RI and S/D between the pregnant women with and without anxiety （ P 〈 0.05 or P 〈 0.01 ）. Conclusion： Maternal anxiety during pregnancy associated with earthquake could obviously affect the fetal physiological states. Ultrasound scan can be recommended as a way to detect the fetal physiological features.
