Abstract:
Objective:To compare the effects of five different types of videolaryngoscopes in patients with a simulated difficult airway.Methods:575 patients who needed endotracheal intubation in Nanjing Hospital Affiliated to Nanjing Medical University from May 2021 to September 2021 were randomly divided into 5 groups [UE videolaryngoscope group (U group), GlideScope videolaryngoscope group (G group), C-MAC videolaryngoscope group (C group), Airtraq videolaryngoscope group (A group) and A. P.advance videolaryngoscope group (AP group)], with 115 patients in each group. They all wore cervical collar to simulate difficult airway. The main observation index was the success rate of first endotracheal intubation. Secondary observation indicators included overall success rate, laryngoscope exposure field, intubation time, operator′s subjective score, cause of failure, adverse events, and complications of intubation.Results:The patients′ mouth opening degree was reduced from (46±6)mm to (24±4)mm ( P<0.05) after wearing the cervical collar; The success rate of the first endotracheal intubation were 96%(UE), 92%(C-MAC), 86%(GlideScope), 85%(Airtraq), and 60%(AP.Advance) respectively, with statistically significant difference ( P<0.05); Compared with AP group and G group, the incidence of soft tissue injury or bleeding in U group and C group were lower ( P<0.05); There were significant difference in the overall success rate of videolaryngoscopes, laryngoscope visual field exposure, intubation time, the subjective score of the operator and adverse events ( P<0.05); There was no significant difference in the complications of intubation among the groups ( P>0.05). Conclusions:Among 575 patients with a simulated difficult airway with limited neck mobility and limited mouth opening, there were significant differences in the use of five videolaryngoscopes. Among them, UE video laryngoscope had the highest first intubation success rate and lowest tissue trauma rate, C-MAC video laryngoscope, GlideScope video laryngoscope and Airtraq video laryngoscope followed in performance, while A. P.Advance video laryngoscope performed the worst.
