The effect of the lateral position on the onset, maximum spread, and duration of anesthesia were observed using a standardized epidural anesthetic technic. Anesthesia appeared 2 minutes earlier on the dependent side, spread 2 spinal segments higher, and lasted 75 minutes longer. These results support the clinical practice of placing the patient in the lateral position with the operative side dependent for induction of epidural anesthesia.
采用标准化硬膜外麻醉技术观察侧卧位对麻醉起效、最大扩散范围及持续时间的影响。麻醉在低位侧提前2分钟出现，扩散范围高出2个脊髓节段，持续时间延长75分钟。这些结果支持在硬膜外麻醉诱导时将患者置于患侧在下的侧卧位的临床实践。
