Abstract

Background: Difficult intubation is always a challenge for anesthesiologists. The study aimed to compare the rates of successful first attempts and upper airway injury when using videolaryngoscope versus direct laryngoscope in patients with predicted difficult intubation. Subjects and methods: a randomized controlled study conducted at Bach Mai Hospital on 104 patients undergoing intubation anesthesia with factors predicting difficult intubation. We randomly divided the patients into two groups: M (n = 52, using a Macintosh direct laryngoscope) and VL (n = 52, using a videolaryngoscope). The main endpoints were the rate of successful first attempts and upper airway injuries. Results: There were no differences between the two groups in anthropometric characteristics or the distribution of factors associated with difficult intubation. The rate of successful first attempts in group VL was 100%, and in group M it was 57.7% (p<0.05). The rate of sore throat at the 6th hour after extubation and bleeding of the lips/tongue, and oropharynx in the VL group was significantly lower than the group M, with the corresponding rates being: 15.6% and 6.9%; 7.8% and 0%; 38.9% and 27.6%, respectively (p<0.05). Conclusion: As compared with a direct laryngoscope, using a videolaryngoscope increases the rate of successful first intubation attempts and reduces bleeding complications and sore throats in patients with predicted difficult intubation.
