Is video laryngoscopy easier than direct laryngoscopy for intubation in patients with contracture neck?

Abstract

Background and Objective: Postburn contracture (PBC) of the neck is commonly seen after acute burn in the face and neck region. Managing the airway is a challenge due to functional and anatomical deformities. We compared the ease of intubation using video and direct laryngoscopes. Material and Methods: Eighty patients, 18–60 years of age with ASA physical status I/II with Onah's types 1 and 2 contracture of the neck were randomized in this study. Group DL were intubated by direct laryngoscopy (DL) using Macintosh blade and Group VL by video laryngoscopy (VL) using King Vision. The outcome measures were ease of intubation (EOI), Cormack-Lehane (CL) grading, and associated complications if any. Results: EOI score was significantly lower in group VL (0.42 ± 0.84) as compared to group DL (0.85 ± 1.21) (P = 0.048) as was the use of external maneuvers (group VL: 17.5%; group DL: 42.5%; P = 0.015), and the use of stylet (group VL: 0%; group DL: 20%, P = 0.005). CL grading improved significantly in group VL (P 3 cm and MPG I/II.
