The objective of this study is to determine if elastic support stockings will significantly reduce the degree to which cardiac output decreases when pregnant women stand. In addition, support stockings may significantly reduce the frequency of uterine activity which follows the change from the supine to standing position. Pregnant women are tested without support stockings, asked to wear the support stockings during all waking hours for one week, and then retested. To date, approximately 1/4 of the anticipated 40 participants have been studied. Recruitment for this project has proven difficult but we will attempt to enroll the balance of the study population in the coming year.

这项研究的目的是确定弹性支撑长袜是否 将显着降低心输出量降低的程度 当孕妇站立时。 此外，支撑丝袜可能 显着降低了子宫活动的频率 从仰卧位转变为站立位置。 对孕妇进行了测试 没有支撑袜，要求在所有人期间佩戴支撑袜 醒来一个星期，然后重新测试。 迄今为止，大约1/4 在预期的40名参与者中，已经进行了研究。 招募 事实证明，这个项目很困难，但我们将尝试注册 来年研究人群的平衡。
