Brief Summary

Obstructive sleep apnea is a common disease, associated with cardiovascular disease, cerebrovascular disease, and many other medical conditions. Therefore the precise diagnosis and treatment are important. With drug-induced sleep endoscopy (DISE), the three-dimensional evaluation of upper airway and airway obstruction could be possible. The problem of the DISE is that there is the difference between a sedative-induced sleep and normal sleep. Moreover there were no standard sedation protocol of DISE. Propofol has short half-life, about 3 minutes, so the patients could recover quickly from it. In recent years, using target controlled infusion(TCI) of propofol, the effective effect-site concentration for DISE could be reached easily with hemodynamic stability and minimal toxic effect. In a previous pilot study, the endoscopy for the diagnosis of sleep apnea could be done successfully with propofol TCI. However there were some desaturation events, although the EEG showed that the patient was not in deep sleep enough. Therefore we thought that not only further study of propofol for DISE but also the study of other drugs for DISE will be needed to overcome this limitation. Dexmedetomidine, the selective α2-adrenoreceptor agonist, has analgesic effect and almost no respiratory depression, therefore it could be a good alternative drug for DISE. The purpose of this study is designing the appropriate sedation protocol for DISE using propofol or dexmedetomidine, and enabling the safer and more accurate DISE.
