Purpose:

1. Video laryngoscope is mainly used for patients with limited head and neck movement (such as cervical spine injury, dislocation of cyclo axial joint), oral and maxillofacial trauma, mouth opening limitation after trauma or burn (but the opening degree is greater than 18mm) and difficult airway patients with high glottic position.

2. Direct rapid intubation through nose.

3. The video laryngoscope can observe the throat structure through the liquid crystal display, and the whole process of inserting the catheter into the glottis improves the teaching efficiency.

advantage:

1. The larynx is easier to expose

2. When video laryngoscope was used for tracheal intubation in patients with cervical cicatricial adhesion, the grade of laryngeal exposure achieved by video laryngoscope was lower than that by direct laryngoscope. Combined use of external laryngeal operation can improve laryngeal exposure grading.

3. It is easy to operate and learn

4. Tracheal intubation injury is small

5. Compared with fiberoptic bronchoscope, GlideScope video laryngoscope has the following advantages: 1) simple operation technology; 2) no restriction on the type of endotracheal tube; 3) less affected by oral and pharyngeal blood and secretion; 4) no obstruction of glottis during tracheal intubation ⑤ The special anti fogging material is adopted, which is not easy to be affected by the temperature difference between the respiratory tract and the external environment, so as to effectively avoid the formation of condensation film on the front surface of the camera and reduce the clarity of the exposed throat.

6. To improve the success rate of endotracheal intubation.

7. Compared with common laryngoscope, GlideScope video laryngoscope has no exposed lighting device circuit contacts in the design, which can reduce the poor contact fault. The laryngoscope is made of special plastic and fully enclosed to protect the camera and optical cable, so it is easier to clean, disinfect and sterilize.
