Dexmedetomidine Versus Remifentanil for Monitored Anesthesia Care During Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration: A Randomized Controlled Trial

BACKGROUND: We hypothesized that, compared to remifentanil, dexmedetomidine used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) performed under monitored anesthesia care (MAC) in nonintubated patients would result in fewer episodes of major respiratory adverse events (number of episodes of bradypnea, apnea or desaturation) but no difference in satisfaction with perioperative conditions. METHODS: Sixty (American Society of Anesthesiologists physical status I–III) patients scheduled to undergo EBUS-TBNA under MAC were randomized to receive either remifentanil (0.5 µg/kg IV bolus) in 10 minutes, followed by 0.05–0.25 µg/kg/min, or dexmedetomidine (0.4 µg/kg IV bolus) in 10 minutes, followed by 0.5–1.0 µg/kg/h. The primary outcome was the number of major respiratory adverse events (bradypnea, apnea, or hypoxia). The secondary outcomes included hemodynamic variables, discharge time from the postanesthesia care unit, endotracheal lidocaine use, patient's sedation using the Observer Assessment of Alertness/Sedation Scale, operative conditions, operator and patient satisfaction, pain, coughing, vocal cord mobility, recall, and nausea/vomiting. RESULTS: Dexmedetomidine produced significantly fewer episodes of major respiratory events (bradypnea, apnea, or desaturation), with 0 [0–0.5] episodes versus 2 [0–5] (median [interquartile range]) (P = .001), than did remifentanil. Fewer episodes of bradypnea or apnea (dexmedetomidine: 0 [0–0] versus remifentanil: 0 [0–0.5]; P = .031), and fewer episodes of desaturation (dexmedetomidine: 0 [0–0.5] versus remifentanil: 1 [0–4]; P = .039) were recorded in the dexmedetomidine group. The time needed for patients to meet postanesthesia care unit discharge criteria (Aldrete score: 9) after EBUS-TBNA was longer in the dexmedetomidine group (10 [3–37.5] minutes) versus the remifentanil group (3 [3–5] minutes) (P
