Extradural Block in Situ for 43 Patients after Puncture of Spinal Dura Mater

硬脊膜穿破后原位实施硬膜外阻滞43例

Methods: Transverse diameters of vertebral canal and spinal dura mater sac were measured on CT images of lumbar spine in 54 cases.

方法：CT测量54例成人腰椎管及相应节段硬膜囊的横径，并计算两者之间的间隙值。

Only spinal dura mater was exposed in the sham operation group, and then the wound was sewn.

假手术组仅显露硬脊膜，然后缝合伤口。

The level of T 11, T 12 anterior spinal roots running through spinal dura mater was higher than that of S 2~ 4 anterior spinal roots originating from spinal cord;

T11、T12前根出硬膜平面均高于S2～4脊神经前根出脊髓平面；

An experimental study on prevention of postoperative adhesion in spinal canal by stored dura mater

保存硬脊膜预防椎管内术后粘连的实验研究

Objective To sum up the feasibility and safety of extradural block in situ after puncture of spinal dura mater.

目的总结硬脊膜穿破后原位实施硬膜外阻滞的可行性和安全性。

Conclusion Extradural block after puncture of spinal dura mater is safe and feasible as soon as it is performed under careful observation.

结论硬脊膜穿破后继续行硬膜外麻醉，只要严密观察，分次，少量给药，是安全可行的。

Conclusion: There is no significant deviation between floating ossification spinal cord decompression and direct resection of ossification, but the former may avoid the injury of spinal cord and dura mater, and to decrease clinic complication.

结论：漂浮骨化灶脊髓减压与直接切除骨化灶脊髓减压平均改善率无显著差异，前者可避免脊髓及硬膜囊损伤，减少临床并发症的发生。

The density of nucleus pulposus herniation is higher than that of spinal dura mater and fat of epidural gap. The essence of soft tissue shadow of epidural gap is nucleus pulposus herniation.

突出的髓核密度高于硬脊膜囊和硬膜外脂肪的密度，硬膜外间隙中的软组织密度影代表突出的椎间盘组织。
