A skill lab training experience with truview video laryngoscope in different airway scenarios using an adult manikin

: Video laryngoscopes enhance laryngeal visibility and improve the chances of successful intubation, especially in difficult airway scenarios. Video laryngoscopes require development of a skill to perform a successful intubation. As with surgical endoscopes and laparoscopes, this device has a learning curve to achieve dexterity in hand-eye co-ordination necessary for intubation. In our study, we studied the learning curve of Truview video laryngoscope. : To evaluate intubation time and study the learning curve of Truview video laryngoscope in easy and difficult airway scenario in adult manikin. Compare ease of intubation with Truview video laryngoscope in both airway scenarios. : After approval of the Institutional ethics Committee, the study was conducted at the skill lab and simulation centre in four sessions. Each session was conducted at a time interval one-week apart. Using Truview video laryngoscope, thirty postgraduate students, were asked to intubate a manikin in easy and difficult airway scenarios. At the end of every session, the parameters pertaining to intubation were recorded. Primary outcome was the time taken for successful intubation and the secondary outcome of ease of intubation was noted. All thirty participants completed the study. : The time required for intubation decreased significantly for Session 1 from 46.77 ± 7.94 to 24.07 ± 5.85 (p<0.001*) in session 4 in the easy airway scenario. In the difficult airway scenario, time decreased from 36.07 ± 4.25 in session 1 to 19.77± 9.38(P<0.001*) in Session 4. Participants also rated the device with respect to ease of intubation significantly better in Session 4 for both easy (IQR- 1-1, p<0.001*) and difficult (IQR- 1-1.25, p<0.001*) airway scenarios. We noted significantly improved learning curve of Truview video laryngoscope in both easy and difficult airway scenarios in the period of our study. : We concluded that the Truview video laryngoscope provides faster intubation time and better ease in handling the device in different airway scenarios in the study period. The device has a quick learning curve and users can become adept in handling intubations, in both easy and difficult airways with a little practice. In the difficult airway, the Truview video laryngoscope achieves faster intubation.
