We have studied the effect of horizontal lithotomy position on the spread of hyperbaric dibucaine spinal anesthesia. In three groups of 20 patients, 7.2 mg of hyperbaric dibucaine was injected intrathecally in the lateral decubitus position. In group supine, the patients were kept in supine horizontal position in which patient's legs and thighs were extended throughout the operation. In group lithotomy A, immediately after the spinal injection, the patients were placed into the lithotomy position. In group lithotomy B, after the spinal injection, the patients were placed immediately in the supine horizontal position for 15 min and then placed into the lithotomy position. There were no significant differences in height of sensory blockade among the three groups. The lithotomy position did not significantly affect the level of sensory blockade with hyperbaric dibucaine.
我们研究了水平截石位对高压丁卡因脊麻扩散的影响。在三组每组20例患者中，于侧卧位经鞘内注射7.2mg高压丁卡因。仰卧组患者在整个手术过程中保持仰卧水平位，双腿和大腿伸直。截石位A组在脊髓注射后立即将患者置于截石位。截石位B组在脊髓注射后，患者立即仰卧水平位保持15分钟，然后置于截石位。三组之间感觉阻滞的高度无显著差异。截石位对高压丁卡因感觉阻滞水平无显著影响。
