Upper Airway Collapse in Patients With Obstructive Sleep Apnea Syndrome by Drug Induced Sleep Endoscopy

Evaluation of the Upper Airway Collapse in Patients With Obstructive Sleep Apnea Syndrome by Drug Induced Sleep Endoscopy According to the Munich Sleep Video Protocol

This is a prospective, interventional cohort study of drug-induced sleep endoscopy (DISE). The goal is to evaluate the upper airway in a cohort of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) diagnosed in a prior polysomnography.

This study correlates the sedation level measured by entropy during DISE using propofol via a TCI pump with the local obstruction patterns of the upper airway according to the VOTE classification.

As OSAHS is a widespread disease and the DISE procedure has become a common tool for diagnosis and evaluation of further treatment, a growing number of research articles deal with this topic. These articles are available through pubmed.
