Comparative Study of King Vision and Vl3r (Hugemed) TM Video Laryngoscope for the Ease of Intubation in Adult Patients Undergoing General Anaesthesia for Elective Surgery

Abstract Background: It is challenging to intubate despite good visualization with hyperangulated blade of video laryngoscope. VL3 video laryngoscope with field angle 66° can save intubation time. We aim to evaluate performance of VL3 video laryngoscope in terms of intubation characteristics. Subjects and Methods: Ours is a prospective observational study. After Institutional Ethics Committee approval, 35 patients were recruited for intubation using VL3 video laryngoscope and King Vision Video laryngoscope each for nonemergency surgery. The primary outcome was intubation time while ease of intubation in terms of Intubation Difficulty Scale, POGO score and hemodynamic responses and complications were noted as secondary outcomes. Inclusion criteria: Ages 18- 60 years, either sex, weight- 45-70 kg, ASA I and II, all MPC grades. Exclusion criteria: past history of failed intubation, Ischaemic Heart Disease, Hypertension, raised ICP, spine /oral pathology, GE reflux. Results: The mean intubation time was 24.742 seconds. 20 patients (57.142%) had a IDS of 0 (easy) .and 30 patients had a POGO score of 1- (85.714%). There were 0 cases of failed intubation even in three attempts. The variations in haemodynamic parameters were found to be statistically insignificant. Discussion and Conclusion: Our mean intubation time was lesser than that of Toker MK2 et al with minimal haemodynamic variations .The VL3 video laryngoscope is an effective device for easy and quick intubation.
