椎管内麻醉是规范化培训的麻醉科住院医师所要求掌握的基本技能,在其规范化培训时期内,要求每人至少实施椎管内麻醉150例。因此在临床工作中,椎管内麻醉中的椎管内穿刺置管大部分是由规范化培训的住院医师完成。虽然住院医师均进行了课堂理论的学习以及基于模型的穿刺流程训练,但是临床的诸多情况依旧导致了带教这部分未在临床操作过的住院医师的困难。比如有的患者由于疾病本身难以摆好理想穿刺体位,从而进一步导致椎间 Intra-spinal anesthesia is a standardized training of anesthesiology residency required by the basic skills required in its standardized training period, requiring at least 150 cases of spinal anesthesia per person. Therefore, in clinical work, spinal canal spinal anesthesia in most of the catheterization is completed by the standardized training of residents. Although both residents learn classroom theory and model-based puncture procedures, many clinical conditions still lead to difficulties in teaching residents who are not clinically operated in this area. For example, some patients because of the disease itself is difficult to put the ideal puncture position, thus further causing intervertebral
