The sedation modality varies among centers and includes moderate sedation/conscious sedation, deep sedation, and general anesthesia. The object of this study will be the evaluation of patient's comfort and level of satisfaction with the involved health care providers (bronchoscopist and anesthesiologist) of remifentanil administration in target-controlled infusion (TCI) for conscious sedation in patients undergoing EBUS‑TBNA, with a prospective randomized study design versus the of standard sedation protocol with midazolam and/or fentanest and/or propofol.</p><p><strong>Methods: </strong>This study was carried out at the \"Campus Biomedico di Roma\" University Hospital between September 2021 and November 2021, with a total number of 30 patients enrolled who met the eligibility criteria, randomly divided into 2 groups: group 1 \"REMIFENTANIL TCI\" (experimental group) where the patients performed the EBUS-TBNA procedure under conscious sedation with infusion of remifentanil TCI with a target between 3 ng/mL and 6 ng/mL and group 2 \"STANDARD\" (control group) with patients undergoing conscious sedation with the association of midazolam and/or fentanest and/or propofol in refracted boluses based on clinical needs.
