摘要

目的：研究正常胎儿呼吸样运动对肺静脉血流频谱的影响及临床意义。方法：应用彩色多普勒超声诊断系统检测43例27~36周正常胎儿肺静脉血流，测量它们在呼吸样运动中及无呼吸样运动时的血流频谱参数：心室收缩期峰值速度（S），心室舒张期峰值速度（D），心房收缩期峰值速度（A），静脉搏动指数（PIV），静脉峰值速度指数（PVIV）。结果：呼吸样运动时，PIV、PVIV降低，A升高。结论：胎儿呼吸样运动时，胎儿左房压减小，胎儿左室顺应性增加。

Abstract

Objective: To research the influence of fetal pulmonary venous velocity waveform during breathing like movements, and to analyse it’s clinical significance. Methods: Pulmonary venous velocity waveform of forty-three normal fetuses between 27 and 36 week’s gestation were examined in apnea(controls) and in the presence of fetal respiratory movements. Fetuses were examined by prenatal Doppler echocardiography with color flow mapping. Peak systolic velocity(S), peak diastolic velocity(D), end diastolic velocity(A), pulsatility index for veins(PIV), peak velocity index for veins(PVIV) were calculated. Results: During fetal breathing movements, PIV, PVIV decreased significantly, whereas A increased. Conclusion: During fetal respiratory movements, the left atrial pressure can be reduced and left ventricular compliance enhanced.
