Comparative Study of Intubation Performance between Macintosh, the Channeled King Vision and the C-MAC D-Blade Videolaryngoscope in Controlled Hypertensive Patients

Abstract

Background: The common cause of anesthesia related injury is inability to intubate the trachea. Video laryngoscopes present an enlarged video image of glottis while intubating the trachea. The aim of this study is to compare efficacy of intubation by Macintosh with C-MAC D-Blade and King Vision video laryngoscope (VL) in controlled hypertensive patients.

Comparison of hemodynamic responses to laryngoscopy and orotracheal intubation between Macintosh laryngoscope and king vision video laryngoscope in adult surgical patients

“…19 However the study by Mogahed et al observed that the success of first trial of intubation was achieved more with KVVL compared to MDL and C-MAC D-blade laryngoscopes but with no statistical significant differences among the three groups. 12 In disagreement with our study, Brueggeney et al showed that the first attempt success rate of intubation was better with C-MAC video laryngoscope than the KVVL. 20 With regard to the post operative oropharyngeal morbidities, in our study, 4 patients in KVVL group and 2 patients in MDL group had oromucosal injuries.…”

“…Mogahed et al also found that lower time was needed for intubation with MDL than KVVL (35.47 ±10.65 Vs 41.53± 9.93 seconds) and the difference was statistically significant. 12 In agreement with our study, Dashti et al inferred that the time for intubation was significantly prolonged with Glidescope compared to MDL (9.80 ± 1.27 Vs 8.2 0 ± 1.17 seconds) (P < 0.05). 17 Tempe et al compared MDL and video laryngoscopes and noted that the duration of laryngoscopy and intubation was significantly less in MDL (36.68 ± 16.15 s) as compared with McGrath (75.25 ± 30.94 s) and TruView (60.47 ± 27.45 s) groups (P = 0.000 and 0.003 respectively).…”

“…They noted statistically significant increase in heart rate and mean arterial pressure with MDL at 2 minutes and 5 minutes after intubation. 12 Similarly, Elhadi et al showed that the mean arterial pressure and heart rate immediately after intubation and 10 minutes after intubation were significantly less in the KVVL group than the MDL group. 13 Woo et al compared Pentax AWS and MDL in burns patients and observed that there were no significant differences in systolic and diastolic pressures between both the groups at various time intervals.…”

“…However the difference was not statistically significant. 12 Another study by Ali et al observed less airway trauma when using KVVL and reasoned that it may be due to absence of direct laryngoscopy like maneuver and the presence of softer blade material. 22 But Soliman et al noted that the incidence of oral trauma and bleeding related to intubation was higher with Glidescope than with MDL which was statistically significant and concluded that the oral trauma maybe due to the multiple trials and difficulty in directing the endotracheal tube to the glottis during intubation with GlideScope.…”

A Randomised Control Study Comparing Hemodynamic Response to Laryngoscopy & Endotracheal Intubation with Macintosh Direct Laryngoscope & C-Mac Video Laryngoscope In Adult Patients

“…[5] To overcome this in recent years video laryngoscopy has been introduced and increasingly used to facilitate endotracheal intubation. [6,7] C-Mac video laryngoscope is a type of video laryngoscope which consists of a standard Macintosh blade with a small camera and a light source at the end of the blade that connects to a video display. 8The present study was conducted to assess hemodynamic responses such as heart rate, systolic, diastolic and mean arterial pressures in patients during endotracheal intubation using the conventional laryngoscope (Macintosh laryngoscope) and the C-MAC video laryngoscope, to assess the success rate of the first attempt intubation using Macintosh laryngoscope and C-MAC laryngoscope and to assess the visibility of the larynx.…”
