An impedance plethysmograph recording was obtained on at least two occasions from 162 women between their 24 and 36th week of pregnancy; 29 while in labor and 21 at the time of their 6-week postpartum visit. There was a significant increase in venous capacitance and a decline in venous capacitance index during apparently normal pregnancy. Those with pregnancy complications (hypertension, premature labor and fetal growth retardation) appeared to have significantly abnormal venous reactivity. It is proposed that equal consideration be given to abnormal venous activity in the mechanisms and therapy of pregnancy-related cardiovascular abnormalities.
对162名妊娠24至36周的女性至少进行了两次阻抗体积描记法记录；29名在分娩时记录，21名在产后6周就诊时记录。在明显正常的妊娠期间，静脉容量显著增加，静脉容量指数下降。患有妊娠并发症（高血压、早产和胎儿生长受限）的女性似乎有明显异常的静脉反应性。建议在与妊娠相关的心血管异常的机制和治疗中，应同等重视异常的静脉活动。
