Propofolsleep - A Study on Cardiopulmonary and Pharyngeal Reactions While Drug Induced Sleep Endoscopy (DISE)

Propofolsleep - A Observational Study on Cardiopulmonary and Pharyngeal Reactions While Drug Induced Sleep Endoscopy in Patients With Obstructive Sleep Apnea Syndrome Under PSI Monitoring

While Drug Induced Sleep Endoscopy (DISE) in patients with obstructive sleep apnea syndrome (OSAS) apnea and hypopnea occur. Because of the induced phases of apnea in a controlled setting it is possible to evaluate the related pathophysiology of apnea. We plan to correlate the Patient State Index (PSI) and other physiologic parameters with phases of apnea and hypopnea.

Detaljeret beskrivelse

DISE is a standard method in diagnosis of OSAS and its specific localisation and severity. 20 patients with polysomnographic diagnosed OSAS will be enrolled in this prospective observational study. All patients would get a DISE because of the before mentioned reasons (localisation and severity) although they wouldn't participate in this study. They will get a 24-h-RR (blood pressure)-measurement, a transthoracic echocardiography, a peak-flow-test and routine lab examination including troponin and proBNP before the examination. Furthermore they have to fill out the Epworth Sleepiness Scale questionaire.

Before starting the DISE a standard-monitoring (Electrocardiography, pulse oximetry, non-invasive blood pressure, patient state index, near infrared spectroscopy, transcutaneous CO2 (carbon dioxide), invasive blood pressure) will be established. After applying the monitoring the DISE is started by target controlled infusion (Marsh Model) with a sighted goal-concentration of 3.0 µg/ml Propofol in 5 minutes. While the examination a stabile snoring-phase with apnoea/hypopnoea is needed. In this moment a video-endoscopy is started to quantify the level of obstruction. After DISE the sedation will end and the patients will be transported to the recovery room or postanesthesia care unit (PACU). For specific order of events a video recording of the DISE will be realized.
