Randomized Controlled Trial Comparative StudyDrug-induced sleep endoscopy: conventional versus target controlled infusion techniques--a randomized controlled study.
Understanding the sites of pharyngeal collapse is mandatory for surgical treatment decision-making in obstructive sleep-apnea-hypopnea syndrome patients. Drug-induced sleep endoscopy (DISE) allows for the direct observation of the upper airway during sedative-induced sleep. In order to re-create snoring and apnea patterns related to a spontaneous sleep situation, the authors used a target-controlled infusion (TCI) sleep endoscopy (DISE-TCI), comparing this technique to conventional DISE, in which sedation was reached by a manual bolus injection. ⋯ Two patients needed oxygen in the conventional DISE group because of severe desaturation that resulted from the first bolus of propofol (1 mg/kg) (P = 0.4872 ns). We recorded the instability of the sedation plan in 13 patients from the conventional DISE group (65%) and 1 patient from the DISE-TCI group (5%) (P = 0.0001). Our results suggest that the DISE-TCI technique should be the first choice in performing sleep endoscopy because of its increased accuracy, stability and safety.
