A Clinical Study on the Application of Multi-Functional Intubating Laryngeal Mask Airway in EBUS-TBNA Technique

Objective: To observe the effectiveness and safety of the multifunctional intubating laryngeal mask airway (LMA) under a jet ventilator applied in EBUS-TBNA technique. Methods: A total of 60 patients who received painless EBUSTBNA were randomly divided into two groups, M and P, out of which group M patients used a normal laryngeal mask supplemented with positive pressure mechanical ventilation, while in group P, a multi-functional intubated laryngeal mask was placed along with a jet ventilator for regular jet ventilation. Mean Arterial Pressure (MAP), Heart Rate (HR), arterial blood gas levels (PaO? and PaO?), operation time, WAKE score, patient and surgeon satisfaction were compared between the two groups. Results: Although the hemodynamics of both groups were stable, the intraoperative and postoperative PaO? levels were significantly higher postoperatively than in preoperative assessment (p<0.05) while the intraoperative and postoperative PaO? levels of group P were more stable than group M which was statistically significant (p<0.05). While there were no statistically significant differences in the operation time, WAKE score or patient satisfaction between the two groups (p>0.05), the surgeon satisfaction in group P was greater than the group M which was statistically significant (p<0.05). Conclusion: The application of multi-functional LMA in EBUSTBNA is a safe and ideal ventilation method, with stable intraoperative hemodynamics, PaO? and PaO? levels, as well as both patient and surgeon satisfaction.
