妊娠高血综合征(简称妊高征)三大症状有高血压、蛋白尿、浮肿,以高血压为最重要。本文以妊高征的定义、病理、治疗为重点作一概述。一、妊高征的定义正常妊娠较未妊娠时心搏出量约增加40%,末梢阻力相应下降,所以收缩期血压几乎不变,舒张期血压于妊娠初、中期稍降低,后期可恢复到非妊娠时水平。妊高征应根据某绝对值以上与妊娠初期比较出现的相对变化来定义。妊娠时血压也有变动,妊高征定义的血压值也会出现各种改变,但通常定为140/90mmHg以上,舒张期为90mmHg以上。不过也有用130/70或135/85mmHg
Pregnancy syndrome (PIH) three symptoms of hypertension, proteinuria, edema, with hypertension as the most important. In this paper, the definition of pregnancy-induced hypertension, pathology, treatment as a focus for an overview. First, the definition of PIH normal pregnancy more than 40% of the volume of gestational out of pregnancy, the corresponding decrease in peripheral resistance, systolic blood pressure is almost unchanged, diastolic blood pressure in early pregnancy, slightly reduced in the middle and later can be restored to Non-pregnancy level. PIH should be based on an absolute value of more than the relative change in early pregnancy to define. Changes in blood pressure during pregnancy, changes in the definition of PIH blood pressure values will also appear a variety of changes, but usually as 140 / 90mmHg above, diastolic for more than 90mmHg. But also useful 130/70 or 135 / 85mmHg
