A randomized controlled clinical trial to compare Hemodynamic Responses to Endotracheal Intubation and Ventilation with Supraglottic Jet Ventilation in Minor Laryngeal Surgeries

Abstract

Background: Laryngeal surgeries tend to produce intense cardiovascular stimulation perioperatively during laryngoscopy, intubation and surgical manipulations. An unobstructed view of airway for surgeon and providing effective ventilation and oxygenation are important goals. A non-intubation technique for maintaining airway patency and ventilation presents a challenging situation for anesthesiologists.Aim of the Study : To compare hemodynamic responses to endotracheal intubation and ventilation with supraglottic jet ventilation in minor laryngeal surgeries. Materials and Methods :The study was conducted at Government ENT Hospital , Koti , Hyderabad, Telangana State, under Osmania Medical College during 2014-2016, the Institutional Ethics committee has approved study,60 patients belonging to both genders in age group of 20-75 years were included in the study and randomly divided into two groups of equal numbers based on ventilation technique used Group E-Endotracheal intubation and ventilation , Group S-Supraglottic jet ventilation , intraoperatively Mean arterial blood pressure, Heart rate and Oxygen saturation (SpO2) were recorded at predetermined time intervals till end of procedures, incidence of adverse events were noted , all procedures lasted for 20 minutes. Results: Intraoperatively Mean arterial blood pressure and Heart rate were significantly lower in Group S (‘p’ value < 0.0001) when compared to Group E.Conclusion: Hemodynamic stability was better with Supraglottic jet ventilation when compared to endotracheal intubation and ventilation in minor laryngeal surgeries.
