OBJECTIVE In this study, we assessed the efficacy of a new method (expansion sphincter pharyngoplasty [ESP]) to treat obstructive sleep apnea. STUDY DESIGN We conducted a prospective, randomized controlled trial. METHODS Forty-five adults with small tonsils, body mass index less than 30 kg/m2, of Friedman stage II or III, of type I Fujita, and with lateral pharyngeal wall collapse were sele...

BACKGROUND Chronic opioid therapy for pain management has increased dramatically without adequate study of potential deleterious effects on breathing during sleep. METHODS A retrospective cohort study comparing 60 patients taking chronic opioids matched for age, sex, and body mass index with 60 patients not taking opioids was conducted to determine the effect of morphine dose equivalent on br...

OBJECTIVE To validate the accuracy of the Bedbugg, a new home monitoring device for diagnosis of obstructive sleep apnea. STUDY DESIGN AND SETTING Simultaneous sleep monitoring was performed by formal polysomnography and by Bedbugg. Monitoring was performed in a university sleep center in 42 subjects who had previously been scheduled for polysomnography. RESULTS The correlation for the apne...

OBJECTIVE Obstructive sleep apnea is frequent during the acute phase of stroke, and it is associated with poorer outcomes. A well-established relationship between supine sleep and obstructive sleep apnea severity exists in non-stroke patients. This study investigated the frequency of supine sleep and positional obstructive sleep apnea in patients with ischemic or hemorrhagic stroke. METHODS P...

Current treatment options are successful in 40% to 60% of children with persistent obstructive sleep apnea after adenotonsillectomy. Residual obstruction assessments are largely subjective and do not clearly define multilevel obstruction. We endeavor to use computational fluid dynamics to perform virtual surgery and assess airflow changes in patients with Down syndrome and persistent obstructiv...

BACKGROUND Obstructive sleep apnea syndrome (OSAS) is characterized by repetitive collapse of the upper airway during sleep. Red blood cell distribution width (RDW) increases platelet activation and has been reported as an independent predictor of adverse outcomes in the general population and is believed to be associated with cardiovascular morbidity and mortality. We evaluated RDW, mean plate...

STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

BACKGROUND Despite the adverse cardiovascular consequences of obstructive sleep apnea, the majority of patients remain undiagnosed. To explore an efficient ECG-based screening tool for obstructive sleep apnea, we examined the usefulness of automated detection of cyclic variation of heart rate (CVHR) in a large-scale controlled clinical setting. METHODS AND RESULTS We developed an algorithm of...

introduction: the berlin questionnaire (bq) is a common tool to screen for obstructive sleep apnea (osa) in the general population, but its application in the clinical sleep setting is still challenging. the aim of this study was to determine the specificity and sensitivity of the bq compared to the apnea-hypopnea index obtained from polysomnography recordings obtained from a sleep clinic in ir...
