What is the current market status of the "video laryngoscope" with a 100% success rate of intubation?

Every year in China, it is estimated that 20 million general anesthesia procedures, 500,000 cardiac arrest patients, and about 1 million or more pre-hospital emergency patients require airway control, or tracheal intubation, to establish an artificial airway, which requires anesthesiologists to be proficient in this skill! However, difficult airway management is a major problem in anesthesia and it often occurs beyond our expectation. If tracheal intubation fails, it will be accompanied by difficulty in mask ventilation and failure to improve oxygenation, which can lead to serious consequences. Once the difficult airway occurs, relevant measures should be taken immediately to remedy it, among which the common remedial tools are basically: videolaryngoscope, fiberoptic bronchoscope, light stick, visual light stick and supraglottic ventilation equipment. 
  • Clinical status of video laryngoscopy
What is the success rate of different remedial tools? Professor Michael F of the Oregon College of Life Sciences, USA, et al, joined forces with seven major medical centers across the United States to conduct a retrospective analysis of difficult airway management.
The study collected 1427 cases of difficult airway encountered in 346,861 intubated patients from 2004 to 2013, and the requirements to be met for final inclusion in the study included that the patients were all adults, the initial tracheal intubation was performed using a plain laryngoscope, and the intubation was unsuccessful, so a remedial strategy of tracheal intubation with a remedial tool was attempted.

The study concluded that after failed common laryngoscopic tracheal intubation, the success rate of video laryngoscopy among the remedial tools was 92%, significantly higher than supraglottic tracheal tube (78%), fiberoptic bronchoscope (78%), light rod (77%), and visual light rod (67%). The use of video laryngoscopy caused few adverse effects, and in addition the study found that more operators, would prefer video laryngoscopy after failed intubation (69%), and this was particularly evident in the recent data (Figure 1).

As time goes by, the use of video laryngoscopes has increased each year, while the use of other tools has gradually decreased. Video laryngoscopes are used not only for difficult airways but also for routine airways, and in the future video laryngoscopes will likely completely replace general laryngoscopes.

Especially in the emergency department and pre-hospital emergency setting, where the incidence of difficult airway is relatively high, and the operators are inexperienced or non-professional in airway management, there is a greater need for video laryngoscopes with high success rate of intubation and easy portability to operate.

In clinical application, the one-time intubation success rate of video laryngoscope can reach 100%, and the time spent is only 23.1s. In contrast, the clinical application effect of fiberoptic laryngoscope is average, and the one-time intubation success rate is only 47.4%, and the time spent is three times that of video laryngoscope.
  • The economic benefits of video laryngoscopy
How much benefit can be created by the video laryngoscope with such favorable future prospect?For the dealer partners, the sale of video laryngoscope not only profits from the equipment, but also from the supply of consumables at a later stage; in addition, for medical institutions, the annual departmental revenue can reach up to several hundred thousand yuan. Here video bend laryngoscope as an example, its use needs to be accompanied by single-use blades for consumables, consumables of different sizes and specifications.
