This prospective randomized study aimed to compare the effectiveness of the intubating laryngeal mask airway (ILMA) with the King Vision Video laryngoscope in aiding endotracheal intubation in Asian patients with normal airway. King Vision Video laryngoscope is a two-piece design. It has a reusable monitor that attaches to disposable blades. The ILMA is a device specifically designed to be an effective ventilatory device and blind intubating guide in patients with normal and abnormal airways.

After ethics committee approval and obtaining patient's written informed consent, 60 American Society of Anesthesiologists grade I and II adult patients undergoing elective surgery requiring intubation were randomly allocated into either the ILMA group (Group L) or the King Vision Video laryngoscope group (Group V).

• Thorough preanesthetic checkup was done. Patient was premedicated. Induction was done with propofol 2.5 mg/kg and succinylcholine 1.5 mg/kg. In Group L, ILMA was inserted using a single-handed rotational technique. In the King Vision Video laryngoscope group, intubation was done with videolaryngoscope. Placement was confirmed with auscultation and capnography.

• An independent observer recorded the following:

– Time taken for successful intubation

– Success or failure of the tracheal intubation

– Number of attempts needed for successful tracheal intubation

– Complication associated with tracheal intubation: bleeding or postoperative sore throat

– Hemodynamic response to intubation

King Vision Video laryngoscope is the more effective technique in aiding endotracheal intubation in patients with normal airways.
