Popis: Objectives/Hypothesis In this study, we compared the effects of propofol and dexmedetomidine on the upper airway collapse pattern and cardiopulmonary parameters of patients with obstructive sleep apnea (OSA) undergoing drug-induced sleep endoscopy (DISE). Study Design Prospective, single center, observational study Materials and Methods The 50 patients with OSA underwent 30 minutes of DISE on 2 different days, the first time with propofol target-controlled infusion (TCI) and the second time with dexmedetomidine TCI. Both the characteristics of upper airway obstruction and cardiopulmonary parameters in response to the depth of sedation achieved with each drug were evaluated. Results The results obtained with propofol and dexmedetomidine DISE were in excellent agreement for all sites of obstruction irrespective of the depth of sedation. Although partial or total obstruction at all areas was consistently observed using both drugs, the degree of upper airway narrowing was slightly lower with dexmedetomidine than with propofol. However, the percentage of patients with a greater than 20% change in blood pressure and heart rate compared to baseline was significantly higher in response to propofol than to dexmedetomidine (P = 0.003 and P < 0.001, respectively). Minimal oxygen saturation was significantly lower in DISE with propofol than with dexmedetomidine (P = 0.004). The percentage of patients with oxygen saturation less than 90% or 80% during DISE was significantly higher in response to propofol than to dexmedetomidine (P = 0.032 and P < 0.001, respectively). Conclusion The DISE findings achieved with propofol and dexmedetomidine were in excellent agreement. However, during DISE, dexmedetomidine provided greater hemodynamic stability and less respiratory depression than propofol. Level of Evidence 4. Laryngoscope, 126:763–767, 2016
