A Comparative Study on Efficacy and Safety of Propofol versus Dexmedetomidine in Sleep Apnea Patients undergoing Drug-Induced Sleep Endoscopy: A CONSORT-Prospective, Randomized, Controlled Clinical Trial

The aim of this study is to compare the efficacy and safety of propofol with dexmedetomidine in patients with obstructive sleep apnea hypopnea syndrome (SAHS) undergoing drug-induced sleep endoscopy (DISE). The 88 patients diagnosed with SAHS in the Affiliated Hospital of Xuzhou Medical University were randomly allocated into 2 groups (n = 44). Patients in the group dexmedetomidine (group D) received continuous intravenous infusion of dexmedetomidine 1 μg/kg over 15 minutes before the endoscopy, and propofol 2 mg/kg was intravenously administrated in the group propofol (group P). Cardiopulmonary parameters of patients were recorded. The time to fall asleep, duration of endoscopic examination, the wakeup time of patients, the number of mask ventilations for patients, the satisfaction of patients and endoscopic performers, and false positive cases of SAHS of patients were compared between the two groups. Compared with group D, mean arterial pressure (MAP) and blood oxygen saturation (SPO2) of patients in the P group were lower at the time point of T1 (P
