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.
Patients and methods: 105 ASA I&II patients (ages 35 to 60) scheduled for elective surgery under general anesthesia were divided into three groups: Macintosh (M), C-MAC D blade(C), and King Vision (K), 35 patients each. Heart rate, mean blood pressure (MBP), SpO2, EtCO2 were recorded at T1: before induction of anesthesia; T2: just before intubation; T3: 2 min after intubation; T4: 5 min after intubation. Primary outcome: time and number of attempts required to successful intubation. Secondary outcomes: ease of laryngoscope insertion, Quality of view, Assist maneuvers, Intubation difficulty, Complications.
Results: Differences in heart rate and mean blood pressure between all groups were statistically significant at T3&T4. Differences in duration of successful intubation were statistically significant between group (M) and group(C), also between group (M) and group (K). Statistically significant differences were obtained between all groups regarding quality of view of glottis, ease of insertion of laryngoscope, and use of assist maneuvers for intubation.
Conclusion: Video laryngoscopes provide hemodynamic stability and better view of glottis than Macintosh during intubation. King Vision VL has advantages of ease of insertion, less need of assist maneuvers for intubation, with less complication. Thus, it is beneficial to use King Vision for intubation in hypertensive patients.
