The aim of the present study was to evaluate the effect of a combination of dexmedetomidine and fentanyl on peripheral oxygen saturation (SpO2) and hemodynamic stability in patients undergoing flexible bronchoscopy. One hundred patients undergoing elective flexible bronchoscopy were randomized into either a propofol-fentanyl group (PF group; n=50) or a dexmedetomidine-fentanyl group (DF group; n=50). SpO2 values, heart rate (HR), systolic and diastolic blood pressure (SBP and DBP), patients' cough scores and discomfort scores as determined by patients and bronchoscopists, levels of sedation, number of times that additional lidocaine was required, elapsed time until recovery, and adverse events were recorded. The mean SpO2 values in the DF group were significantly higher than those in the PF group (P<0.01), and HR, SBP and DBP were significantly lower in the DF group than in the PF group (P<0.05). There were no statistically significant differences between the two groups in terms of cough scores or discomfort scores, sedation levels, or number of times that additional lidocaine was required (P>0.05). Elapsed time until recovery in the DF group was significantly longer than in the PF group (P=0.002). The incidence of hypoxemia was significantly lower in the DF group than in the PF group (P=0.027), but the incidence of bradycardia was significantly higher in the DF group than in the PF group (P=0.037). Dexmedetomidine-fentanyl was superior to propofol-fentanyl in providing satisfactory SpO2. Furthermore, dexmedetomidine-fentanyl attenuated hemodynamic responses during bronchoscopy and maintained hemodynamic stability in the early stage of the procedure.
