Twelve healthy pregnant women were studied at 15, 25, and 35 weeks' gestation and at 8 to 12 weeks postpartum. Women were immersed for 20 minutes at 30 degrees C. They then exercised at 60% maximum oxygen capacity on a modified ergometer. Substantial diuresis and natriuresis occurred without changes in osmolarity or serum sodium. The diuresis was significantly greater during pregnancy than postpartum. The natriuresis was similar. Diuresis and natriuresis were greater than would be expected from investigations in nonpregnant subjects. This study suggests that immersion may be a beneficial therapy for edema without decreasing plasma volume.
对12名健康孕妇在妊娠15周、25周和35周以及产后8至12周进行了研究。将这些女性置于30摄氏度的水中浸泡20分钟。然后她们在改良测力计上以最大氧容量的60%进行运动。出现了大量利尿和利钠现象，而渗透压或血清钠没有变化。孕期的利尿作用明显大于产后。利钠情况相似。利尿和利钠作用比非妊娠受试者的研究预期更为显著。这项研究表明，浸泡可能是一种治疗水肿的有益疗法，且不会减少血浆量。
