Abstract

Background: Intubating oral airways are widely used during fibreoptic orotracheal intubationin order to improve the bronchoscopic visualisation of the glottis and facilitate the procedure. This study compares the visualisation of the glottic opening with bronchoscope using Berman or Ovassapian intubating airway.Methods: We conducted a randomised comparative prospective study one hundred twenty patients with no clinical indicators of the difficult airway. The two oral intubating Berman and Ovassapian airways were compared during fibreoptic endotracheal intubation in anaesthetized patients. The bronchoscopic view, bronchoscopic time, and the total time for intubation were compared.Result: The bronchoscopic view was significantly better with Berman intubating airway (unobstructed view 74%) as compared to the Ovassapian airway (unobstructed 38.4%) (p-value 0.002). The Berman airway provided a significantly shorter duration for visualisation of the vocal cord and intubation of trachea in comparison to the Ovassapian airway.Conclusion: Berman airway provided a better bronchoscopic view as well as shorter bronchoscopic and intubation time as compared to the Ovassapian airway.

Highlights

Endotracheal intubation using fibreoptic bronchoscope is nowadays widely used procedure and can be life-saving in difficult airway scenario.[1]
In an effort to reduce the failure of fibreoptic intubation and improve the bronchoscopic visualisation, various intubating oral airways (IOA) have been designed and they are widely used during fibreoptic orotracheal intubation.[3]
Endotracheal intubation using fibreoptic bronchoscope can be a useful tool for securing the airway in patients with difficult airway.[7]

Summary

Introduction

Endotracheal intubation using fibreoptic bronchoscope is nowadays widely used procedure and can be life-saving in difficult airway scenario.[1]. There are, at present, a number of such airways available, including the Berman, Williams and Ovassapian intubating airway.[4] Berman and Ovassapian intubating airways are the most commonly used intubating airways during fibreoptic orotracheal intubation. These airways help to remove visual obstruction due to the tongue and posterior pharyngeal structures and making a clear path, provide a firm hold of the bronchoscope in the midline, prevent the patient from biting the insertion cord and provide a patent airway for spontaneously or mask ventilated patient. This study compares the visualisation of the glottic opening with bronchoscope using Berman or Ovassapian intubating airway
