Background and Aims: Videolaryngoscopes are crucial components of a difficult airway cart. Issues of cost and availability, however, remain a problem. We compared the combination of an endoscope used in conjunction with the Macintosh laryngoscope with established videolaryngoscopes and the Macintosh laryngoscope using the intubation difficulty scale (IDS) score. Materials and Methods: A prospective randomised study including 120 adult patients, American Society of Anaesthesiologists (ASA) physical status I–III, with an anticipated difficult airway scheduled for elective surgery were randomly allocated to one of four groups: Truview EVO2 (group 1), C-MAC D Blade (group 2), videoendoscope (group 3), or Macintosh laryngoscope (group 4). The IDS score was the primary outcome. Secondary outcomes included the Cormack–Lehane grade, time to tracheal intubation, haemodynamic responses, and adverse events. Results: A significant proportion of patients in groups 2 and 3 had an IDS score of zero (73.3 and 70%, respectively). IDS scores were significantly lower in the C-MAC D blade and videoendoscope groups attributable to differences in parameters N4, N5 and N6 [C/L grades, lifting force and laryngeal pressure required] ( P < 0.001). The C-MAC D blade and the Macintosh laryngoscope required less time for intubation as compared to the Truview EVO2 and videoendoscope. No differences were noted in post-intubation haemodynamic parameters and other adverse events. Conclusion: The performance of videoendoscope was comparable to C-MAC D Blade and superior to Truview EVO2 and Macintosh laryngoscope with respect to the IDS score and may thereby provide an effective alternative to commercial videolaryngoscopes in low resource settings.

“…[10] Laparoscopes are now freely available in most setups without the additional cost of a videolaryngoscope designed to tackle difficult airway, to provide a clear anatomical view of the glottic area, to be able to ‘look around the corner’,[3] and to view the glottis via the camera without aligning the oral, pharyngeal and laryngeal axes. Therefore, a potential C and L grade III or IV glottic view should become a C and L grade I or II view with laparoscopic assistance.…”

Background:To use laparoscope as an easily available and easy to use alternative option to videolaryngoscope.Aims:The aim of the study was to assess the improvement in the glottic view using a conventional direct laryngoscope (DL) assisted by a laparoscope with its endovision system along with the time taken for tracheal intubation.Settings and Design:A prospective, double blind, randomized, controlled study was conducted in a tertiary care centre.Methods:Sixty patients with American Society of Anesthesiologists (ASA) physical status I and II requiring general anaesthesia and tracheal intubation for elective surgery were included in the study. The patients were anaesthetized, paralysed, DL was performed and Cormack and Lehane grade (C and L) noted, followed by the introduction of the laparoscope alongside the flange of the Macintosh laryngoscope and a further C and L grading done as seen on monitor. Demographic data, ASA physical status, airway assessment, mouth opening, modified Mallampatti class, jaw protrusion, thyromental and sternomental distances, optimal external laryngeal manipulation, time taken for intubation, pulse oximetry, blood on; tracheal tube, lip, dentition or mucosal trauma, sore throat, hoarseness of voice, excessive secretions and regurgitation were recorded.Statistical Analysis:Statistical analysis was done using statistics package for social sciences software (17.0 version). A P-value less than 0.05 was considered statistically significant.Results:Eighty-three percent of the patients showed improvement in glottic view after laparoscopic assistance. Eighty-one and 85% of the patients with C and L grade II and III respectively on DL had an improved glottic view with this technique. The mean time to intubate was 37 seconds.Conclusions:Laparoscopic assistance provided a better glottic view than DL in most patients (83%). It has a potential advantage over standard DL in difficult intubation.
