In 20 gynecological patients, the radionuclide was injected through the epidural catheter to determine the effect of the posture on the distribution of the radionuclide in the epidural space. Each 5 were placed on supine, right decubitus, left decubitus or sitting position and the posture was maintained for 30 min after the injection of the radionuclide. The distribution of the radionuclide in the epidural space was determined by measurement of gamma ray by a gamma camera. The data were stored and analyzed by a digital computer (SINTIPAC). In supine and right decubitus position, the radionuclide was distributed more on the right side and in the left decubitus position the radionuclide was distributed evenly. In the sitting position the radionuclide was distributed more caudad and the cephalad distribution was limited compared to the other postures. In summary the solution in the epidural space may move by the gravity but these effects were very slight and are of only minor clinical significance.
在20例妇科患者中，通过硬膜外导管注入放射性核素，以确定体位对放射性核素在硬膜外腔分布的影响。每5例分别置于仰卧位、右侧卧位、左侧卧位或坐位，注入放射性核素后保持该体位30分钟。通过γ相机测量γ射线来确定放射性核素在硬膜外腔的分布。数据由数字计算机（SINTIPAC）存储和分析。在仰卧位和右侧卧位时，放射性核素更多地分布在右侧；在左侧卧位时，放射性核素分布均匀。在坐位时，放射性核素分布更靠下，与其他体位相比，头侧分布受限。总之，硬膜外腔中的溶液可能会因重力而移动，但这些影响非常轻微，仅具有较小的临床意义。
