Abstract

We have examined the extradural space using a flexible extraduroscope in 74 patients undergoing extradural anaesthesia at the L2-3 interspace. Extraduroscopy showed that the extradural space becomes widely patent and the fatty tissue in the extradural space diminishes with increasing age. We postulate that these age-related structural changes may affect the spread of local anaesthetic in the extradural space.

摘要

我们使用可弯曲硬膜外腔镜对74例在L2 - 3间隙接受硬膜外麻醉的患者的硬膜外腔进行了检查。硬膜外腔镜检查显示，硬膜外腔随着年龄增长而变得更宽敞，硬膜外腔内的脂肪组织减少。我们推测，这些与年龄相关的结构变化可能会影响局部麻醉药在硬膜外腔的扩散。
