TI  - A comparison of angled (D-Blade) and Macintosh (C-MAC) videolaryngoscopes for
simulated pediatric difficult airway: a randomized single-blind study
AB  - Background/aim: Being prepared for difficult airway (DA) is nevertheless of great importance. Failed or delayed tracheal intubation
(TI) can increase morbidity and mortality, and the pediatric population is more prone to hypoxia. With the development of different
types of videolaryngoscope (VL), these have become the device of choice in patients with DA.
Our primary aim was to compare intubation times with D-blade and Macintosh blade of Storz C-MAC®
 in a simulated pediatric DA
scenario with this randomized controlled trial.
Materials and methods: Children aged 1-5 years scheduled for elective surgery were included in the study. Patients were randomized
into two groups: the D-Blade (n = 20) and MAC (n = 21) groups. All children underwent inhalational induction, and a neuromuscular
relaxant was routinely administered (rocuronium 0.6 mg.kg-1). After the appropriate size of semirigid foam neck collar had been
positioned around the patient’s neck, the D-Blade group patients were intubated using a size 2 D-Blade, and the MAC group patients
used a size 2 VL Macintosh blade. Intubation, time was measured. Patients’ modified Cormack-Lehane system scores (MCLS), pre and
postintubation blood pressure values and heart rates, and complications during intubation were recorded.
Results: Demographic data were similar between the groups. There were also no significant differences in pre and postintubation heart
rates, blood pressure, or SpO2 values (p > 0.05 for all). Mean intubation times for the MAC and D-Blade groups were 12.14 ± 2.79 s and
18.31 ± 10.86 s, respectively (p = 0.022). MCLS scores were lower in the D-Blade group (p = 0.030).
Intubation success rates were 100% in the MAC group and 90% in the D-Blade group, although the difference was statistically
insignificant (p = 0.165).
Conclusion: A better laryngoscopic view was obtained with D-Blade. However, the Storz® C-Mac videolaryngoscope Macintosh blade was superior to the D-Blade in achieving a shorter time for TI.
