硬膜外麻醉误入硬膜下腔的解剖学研究

Anatomy research of subdural cavity anesthesia in the exceptional level of anesthesia operation

目的通过对硬膜下腔的解剖研究,为临床麻醉医师解决异常平面阻滞提供理论依据,并利用硬膜下腔麻醉进行手术。方法 1)通过对成人尸体标本脊柱的解剖,证明硬膜下腔的存在。2)通过对婴儿脊髓切片的染色,从微观角度进一步证明硬膜下腔的存在。结果 1)成人尸体标本上硬膜下腔容易分离。2)婴儿脊髓标本切片HE染色进一步证明硬膜下腔存在。结论本实验证明硬膜下腔是真实存在的腔隙,而并非是导管的解剖作用。硬膜下腔的解剖学特点可以对临床上出现麻醉平面过广作出合理化解释。

Objective Using the anatomy research of subdural cavity to provide clinic theory evidence for anesthetist for resolve the exceptional level of anesthesia.And utilize the method of subdural cavity anesthesia in the operation.Methods 1）Anatomizing the adult＇s column vertobralis to prove the existence of subdural space.2）Dyeing the slice of infantum＇s spinal cord to prove the existence of subdural cavity,furthermore,from the microscopic point of view.Results 1）It is easier to separate subdural cavity from the adult.2）Using the method of HE stain in the slice of infantum＇s spinal cord to give more evidence of the existence of subdural cavity.Conclusions The experiment certificate the subdural cavity is a real lacouna.And it is not the anatomical function in lacouna.The anatomy characteristic of subdural cavity can explain the reason of have a broad level of anesthesia in clinic more reasonable.
