Polysomnography (PSG) is an essential component of the preoperative workup for patients undergoing bariatric surgery because clinical parameters (BMI, neck circumference, Epworth Sleepiness Scale) are inadequate predictors of Obstructive Sleep Apnea (OSA).
If you are having weight loss surgery, do not skip the sleep study. Feeling tired or having a large neck does not reliably tell you if you have sleep apnea. You need a full night sleep study (PSG) before surgery to ensure you are safe during anesthesia and recovery.
We contend that all three clinical parameters are inadequate predictors of OSA and that PSG is an essential component of the preoperative workup of patients undergoing BS.
Why this rating
Prospective observational study with a large sample size (n=279) and rigorous statistical analysis, though single-center.
