For intubation, in recent years, as various novel gas passage tools enter clinic, the case where handling difficult airway, is improved, but tired
Difficult trachea cannula is still the problem of being commonly encountered day, and is even more to determine Clinical Processing method and consequence with the presence or absence of difficult ventilation
Key, therefore according to whether there is or not difficulty ventilation difficult airway is divided into non-emergency air flue and acute disease air flue again.Non-emergency air flue: only
Have any problem trachea cannula and without difficult mask ventilation in the case where, patient is able to maintain that satisfied ventilation and oxygen are closed, and can allow for
The method for thering is the sufficient time to consider that other establish air flue.This simple difficult intubation air flue is defined as non-emergency air flue.
Acute disease air flue: when difficult mask ventilation has difficult tracheal intubation concurrently, patient is in urgent anaerobic condition, it is necessary to promptly establish gas
Road, this air flue for being unable to positive airway pressure while may merging difficult tracheal intubation are defined as acute disease air flue.It is unable to mask ventilation
Being unable to trachea cannula again can lead to the serious consequence of tracheotomy, cerebral injury and death.And the technical difficulty of tracheotomy is larger,
Damage is big, and the doctor without special training cannot usually be completed in a short time surgery airway open, and have plugging difficulty in decannulation,
The complication such as poor wound healing and tracheostenosis, lead to patient's anoxic or life danger.
Utility model content
The utility model is limited for the ventilation of acute disease air flue patient, design it is a kind of can quick and precisely backward trachael intubation
