Comparison of Tritube™ tube and Evone® ventilator use with traditional narrow-lumen tube use in microlaryngeal surgery cases

Abstract

Aim: To evaluate the feasibility and safety of the Tritube™ tube and Evone® ventilator and compare patients intubated using Tritube™ and ventilated with flow-controlled ventilation (FCV) using Evone® (TT–FCV group) to those intubated using a traditional microlaryngeal intubation tube and ventilated with volume-controlled ventilation (MLT-VCV group) in terms of perioperative parameters and outcomes during microlaryngeal surgery (MLS). Material and Method: A prospective observational design was conducted. This study was carried out in 6 (six) months between February 2022 and September 2022. After receiving their informed consent, 18 patients were randomly assigned to two groups. Patients older than 18 years, who were scheduled for elective MLS were included in the study. The closed opaque envelope method was used for randomization. The same standard anesthesia protocol was applied to all patients. The patients’ demographic parameters, American Society of Anesthesiology physical status (ASA), Mallampati and Cormack-Lehane scores, duration of ventilation, duration of surgery, hemodynamic parameters, ventilation parameters, and complications were recorded. Results: Twenty-one patients recruited for the study. Three of them regretted to participate to study. At the end 18 patients were analyzed. The mean age of population was 53(43-62). When the intraoperative respiratory and hemodynamic parameters of the patients were compared between the two groups, the regional cerebral oxygen saturation (rScO2) (p=0.020), tidal volume (p=0.005), compliance of the respiratory system (p=0.001), and post-extubation rScO2 (p=0.001) values were statistically significantly higher in the TT-FVC group compared to the MLT-VCV group. Right rScO2 (p=0.038), left rScO2 (p=0.047), and time to extubation (p=0.021) were statistically significantly lower in the TT-FVC group compared to the MLT-VCV group. Conclusion: According to the findings we obtained, utilizing Tritube™ and Evone® during MLS surgeries appears to be effective in terms of achieving safe airway management.
