研究目的:

本研究旨在通过比较观察注射等效剂量的去氧肾上腺素和去甲肾上腺素来治疗PIH 产妇的腰麻后低血压时,彩色多普勒超声检查子宫动脉和脐动脉的搏动指数(PI)和阻力指数(RI)的变化情况,来分析不同血管活性药物对胎盘循环的影响。  

Objectives of Study:

The aim of this study was to analyze the effects of different vasopressors on placental circulation by comparing the pulsatile index (PI) and resistance index (RI) in uterine and umbilical arteries of pre-eclamptic patients with postspinal hypotension treated by injection of equivalent dose of phenylephrine and norepinephrine.
