Catheterization of the renal vein offers a safe and relatively simple method of obtaining blood as it leaves the kidney in the resting unanesthetized human subject. In preliminary observation on 8 subjects the renal arteriovenous oxygen difference varied from 1.9 to 2.8 volumes per cent., averaging 2.3 volumes per cent. Sodium para-amino hippurate, at low plasma levels, was 88 per cent. extracted during a single circulation through the kidney.
肾静脉插管为从休息状态未麻醉的人体中获取血液提供了一种安全且相对简单的方法。在对 8 名受试者的初步观察中，肾动静脉血氧差从 1.9 到 2.8 体积%不等，平均为 2.3 体积%。在单次肾脏循环中，低血浆水平的对氨基马尿酸钠的提取率为 88%。
