A Study Comparing Sevoflurane and Propofol in Patients Undergoing Endobronchial Ultrasound Guided Needle Aspiration

Plain-language summary

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure used to obtain samples from mediastinal and hilar lymph nodes or lung parenchymal lesions for diagnostic and staging purposes. The success and safety of the procedure, including diagnostic yield, complication rates, and bronchoscopist comfort, depend largely on the choice of anesthesia technique. General anesthesia is frequently preferred because it provides a stable airway, adequate ventilation, and improved procedural conditions. Patient-related factors such as medical status, history, procedure duration, and number of needle passes may influence hemodynamic stability and tolerance, making anesthesiologist involvement essential. Previous studies comparing intravenous and inhalational anesthesia in various surgical and bronchoscopic procedures have evaluated their effects on hemodynamics, complications, recovery time, visibility of the surgical field, and postoperative outcomes. However, there is limited evidence directly comparing propofol-based total intravenous anesthesia and sevoflurane-based inhalational anesthesia specifically for EBUS-TBNA. This study aims to compare the effects of propofol and sevoflurane anesthesia on perioperative hemodynamic parameters, respiratory stability, and procedure-related complications in patients undergoing EBUS-TBNA. In addition, the study assesses bronchoscopist satisfaction with each anesthetic technique, including procedural comfort and working conditions. The findings are expected to contribute to optimizing anesthetic management for EBUS-TBNA, improving patient safety, and enhancing procedural quality.
