Obstructive Sleep Apnea After Surgery

Does OSA affect cardiopulmonary complications?

Publish date:: August 25, 2015

Patients with obstructive sleep apnea (OSA) who are not treated with positive airway pressure preoperatively are at increased risks for cardiopulmonary complications after general and vascular surgery, according to a study of 26,842 patients, including 2,646 with a diagnosis or a suspicion of OSA. Of the patients with OSA, 1,465 were untreated. Researchers found that compared with treated OSA, untreated OSA was independently associated with:

• More cardiopulmonary complication [adjusted odds ratio (aOR), 1.8]

• More unplanned reintubations (aOR, 2.5)

• More myocardial infarction (aOR, 2.6)
