About

Sleep apnea syndrome (OSA) frequently occurs in obese population undergoing bariatric surgery. There is a need for alternative screening tools for sleep apnea detection in the pre-operative period. The investigators would like to compare ApneaLink and complete polysomnography in this population.

Full description

OSA can occur in up to 78% of patients undergoing bariatric surgery(1). Moderate to severe case will benefit from CPAP therapy, that can help avoiding post-operative complications(2).

In this population, the investigators propose complete attended in-hospital polysomnography (PSG)in patients with a clinical high probability of OSA.

According to obesity epidemics (3), waiting list for PSG in sleep labs is every day longer.

The investigators want to assess sensitivity and specificity of a new portable screening tool, ApneaLink, to detect OSA in a bariatric population.

Design:

monocentric and prospective study

Methods:

Patients:

OSA suspicion based on :

symptoms and signs (snoring, apneas , neck circumference >38 (women) or 43cm (men))
BMI > 50
BMI > 40, > 40 y
BMI > 35, men, hypertension
increased serum Bicarbonate
Polyglobulia

Measurements

Polysomnography in sleep lab with concommitant recording performed with Apnea LinkTM (nasal flow and oxymétry recording).
between 2 weeks : recording performed with Apnea LinkTM (nasal flow and oxymétry recording)at home.
