Application of Vathin single-use flexible video bronchoscope in difficult airway management

Question

Difficult airway

means the expected or unexpected difficulties or failures in airway management encountered by clinicians trained in clinical anesthesia, including but not limited to one or more of the following situations.

Question

Decision-making process for difficult airway?

决策流程

Emergency airway management can be divided into two steps.

Step 1Ensure ventilation and oxygenation, while initially assessing airway conditions. The primary goal is to ensure the patient's life safety. Meanwhile, the airway condition of patients is initially assessed according to the "CHANNEL principle".

Step 2: clear airway conditions, establish artificial airway. 。During this stage, the patient's airway condition should be clarified, and preparations should be made according to the "step-down" approach. It is recommended to use an airway management cart to provide readily available airway management equipment and quickly establish an artificial airway. Patients with conditions may opt for the rapid induction and intubation procedure. When encountering difficult airway, follow the principle of "priority to maintain ventilation and oxygenation", and avoid blindly trying multiple times. The construction method of artificial airway follows the principle of "simple, effective and minimal trauma", and the visualization technology is preferred.

Question

How to choose the tracheal endoscope model for tracheal intubation?

01.

Tracheal tube model selection

Adults：

	Tube diameter （inside diameter）	Intubation depth （from incisor）
Female	7.0～8.0	About 21cm
Male	7.5～8.5	约22cm
nasotracheal intubation	6.5～7.0	It should be 3 cm longer than the standard length for transoral intubation
*If there is airway stenosis, the inner diameter of the trachea stenosis should be measured by X-ray. Subtract 1.5 cm, which is equivalent to the outer diameter of the catheter, and prepare two smaller catheters in turn。

Children：

Children：

(1)Catheter number (ID)= age (years)/4+4;

(2)Length of catheter insertion (to incisor, cm)= age (years)/2+12;

(3)Children have significant individual differences, so it is also necessary to prepare larger and smaller catheters. Children under 5 years of age generally do not use a cuffed endotracheal tube, and a smaller cuffed endotracheal tube should be used if they need it.。

02.

Tracheal endoscope model selection

The choice should be based on the inner diameter of the endotracheal tube and the outer diameter of the bronchoscope, and the inner diameter of the endotracheal tube must be approximately 1.0-1.5 mm larger than the outer diameter of the bronchoscope.

The relationship between airway pressure and the inner diameter of the endotracheal tube and the outer diameter of the bronchoscope: The level of the airway pressure is related to the inner diameter of the endotracheal tube and the outer diameter of the bronchoscope. For the same diameter of endotracheal tube, airflow resistance is lower with the insertion of a finer model bronchoscope, resulting in lower airway pressure and PEEP effect.

Therefore, the thickest possible model of organ catheter or the thinnest possible model of bronchoscope should be selected when choosing.
