文献报导某些类型高血压病的交感神经素统亢进,25～40%的原发性高血压病血中儿茶酚胺升高,改变体位时加甚。但对妊娠高血压病的肾素血管紧张系统的作用尚有争论。作者为进一步证明某些类型高血压病时交感神经系统亢进,测定了高血压孕妇血浆肾上腺、去甲肾上腺素和多巴胺的水平。作者研究了9例妊娠高血压和7例妊娠末期正常血压孕妇。由于静脉穿刺、运动和改变体位均可影响血浆儿茶酚胺水平(Carruthers等,1970;Lake等,1976)。为减少干扰采集连续两天标本,患者从上午8～9时取左侧静卧位,将肝素化导管插入血管,30分钟后抽血20ml,放入含400ml还原
Reported in the literature of some types of hypertensive sympathomimetics hyperthyroidism, 25-40% of essential hypertension blood catecholamines increased, when changing the position plus. However, the role of renin-angiotensin system in pregnancy-induced hypertension remains controversial. To further prove that some types of hypertensive sympathetic nervous system hyperthyroidism, determination of plasma levels of adrenal, norepinephrine and dopamine in hypertensive pregnant women. The authors studied 9 cases of pregnancy-induced hypertension and 7 cases of normotensive pregnant women at the end of pregnancy. Plasma catecholamine levels can be influenced by venipuncture, exercise, and changing body position (Carruthers et al., 1970; Lake et al., 1976). In order to reduce interference collected two consecutive days of specimens, the patient from 8 am to 9 pm left supine position, the heparinized catheter is inserted into the blood vessels, after 30 minutes blood 20ml, placed in 400ml reduction
