PurposeSuccessful intubation is challenging in patients with bilateral mandibular fractures. The aim of this study was to compare video laryngoscope (VL) and Macintosh laryngoscope (ML) for intubation of patients with bilateral mandibular fractures.Materials and MethodsIn this randomized control trial study, patients who had bilateral mandibular fractures (angle or subcondylar) were studied. Patients were randomly assigned into two groups using computerized randomization. In group 1, laryngoscopy was performed by ML, while VL was used for patients in group 2. The intubation device (ML or VL) was the predictive factor of the study and age, maximum mouth opening (MMO),incisor fracture and gender were the variables. The intubation time and successful intubation in the first attempt were the study outcomes. The independent t-test was applied to compare the intubation time, MMO and age between the two groups.ResultsSeventy-eight patients were studied (40 patients in group 1 and 38 in group 2). The mean intubation time was 33.02±9.68 seconds in group 1 and 39.16±7.40 seconds in group 2. Comparison of the data demonstrated a significant difference between the two groups (P=0.002). Twenty-four patients in group 1 and 31 in group 2 were successfully intubated in the first attempt. There was a significant difference in the number of successful or failed intubation attempts between the two groups (P=0.03).ConclusionAccording to the findings, use of VL increased the first-attempt success rate of intubation in patients with bilateral mandibular fractures. Time of intubation may be longer when using VL than ML.
