Abstract
Background: With advances in technology, intubation using video laryngoscopy has been gaining popularity, particularly in patients with difficult airways or as rescue devices in failed intubation attempts. Their routine use is, however, an uncommon occurrence. This clinical trial was carried out to support their use in elective airway management. Objective: To evaluate the effectiveness of kingvision video laryngoscope (KVL) in comparison with the Truview video laryngoscope (TVL) in routine airway management. Methods: We studied 60 subjects requiring orotracheal intubation during general anaesthesia for elective surgeries. They were randomly assigned into two groups to undergo tracheal intubation using either a TVL (n=30) or KVL (n=30) .Characteristics and consequences of airway management were evaluated. The primary outcomes were the percentage of glottic opening (POGO) and ease of intubation and secondary outcomes were Cormack and Lehane (CL) grading, TTI (time taken for intubation) and successful placement of endotracheal tube (ETT). Results: Both the VLs were comparable with respect to primary and secondary outcomes except TTI which was more with KVL. Conclusion: We opine that both TVL and KVL provide a better laryngoscopic view in routine airway management, but KVL does not have an extra benefit over TVL otherwise, further indicating the need for more experience with the use of a KVL.
Highlights
Practitioners involved in airway management have a plethora of tools often purported as rescue devices after failed direct laryngoscopy (DL)
The primary outcomes were the percentage of glottic opening (POGO) and ease of intubation and secondary outcomes were Cormack and Lehane (CL) grading, TTI and successful placement of endotracheal tube (ETT)
The present study evaluates and compares the efficacy of these two Video larygoscopes (VLs) for tracheal intubation based on the primary outcomes POGO and ease of intubation and secondary outcomes CL grading, TTIand successful placement of ETT
Summary
Practitioners involved in airway management have a plethora of tools often purported as rescue devices after failed direct laryngoscopy (DL). KVL is a new VL which provides indirect view of the glottis (figure 1) It consists of reusable anti-reflective display and a single use ergonomic blade/handle. Intubation using video laryngoscopy has been gaining popularity, in patients with difficult airways or as rescue devices in failed intubation attempts. Their routine use is, an uncommon occurrence.

Conclusion: We opine that both TVL and KVL provide a better laryngoscopic view in routine airway management, but KVL does not have an extra benefit over TVL otherwise, further indicating the need for more experience with the use of a KVL
