经胸12腰1棘突间隙行硬膜外穿刺的风险及改进
The risk and amendment of epidural puncture at T12-L1interspinous space

经胸12腰1棘突间隙穿刺时，损伤脊神经的几率较大。对脊神经受损伤的病例进行分析，发现导致损伤的主要原因是在胸12腰1棘突间隙的硬膜外腔最狭小。因此，笔者认为，从解剖学和硬膜外穿刺的特点来说，胸12腰1棘突间隙不适合行硬膜外穿刺。
There is a high probability of spinal cord injury when epidural puncture is performed at T12-L1interspinous space. Based on the analysis regarding the reasons of spinal cord injury cases, the author holds that the mainreason of spinal cord injury may be the narrow epidural space at T12-L1 interspinous space. From the anatomy and thecharacteristics of epidural puncture, T12-L1 interspinous space is unfit for epidural puncture
