[Research Progress in Adjacent Anatomical Structure and Location of Cricothyroid Membrane].

Cricothyroid membrane puncture and incision,the key techniques to save the lives of the patients in the Can't Intubate,Can't Oxygenate (CICO) emergency,need to be mastered by all the airway management staff.However,the decision to carry out cricothyroid membrane puncture or incision is often delayed due to the unfamiliarity with the adjacent anatomical structure of the cricothyroid membrane and the inability to accurately locate the cricothyroid membrane.As a result,serious complications and rescue failure occur.Therefore,airway management staff should be familiar with the adjacent structure and positioning methods of the cricothyroid membrane,so as to improve the success rate of emergency airway rescue,reduce complications,and protect the airway and life safety of the patients.
