Results The anesthesia range was narrowed and anesthesia duration was shortened with the prolongation of epidural catheter placement,Epidural roentgenography showed that the medium diffused normally within epidural space,biopsy of epidural tissues showed that there were inflammative cells infiltration and fiber proliferation with longer epidural catheter placement（more than 4 weeks）,without significant differences between both groups.Conclusion Epidural corticosteroids can not prevent epidural adhesion from occurrance induced with long-term epidural catheter placement.

结果 随着硬膜外腔置管时间延长，麻醉阻滞范围变窄，麻醉阻滞时间也明显缩短，两组之间没有明显区别；硬膜外腔造影显示：造影剂在硬膜外腔扩散良好，无明显受阻；组织学检查显示：置管时间长(4周以上)的动物，硬膜外组织炎细胞浸润、纤维组织增生、硬膜增厚，而且随置管时间延长，这&种变化更&加显著，但两组之间没有明显区别。
