Wagner S, Sutter L, Wagenblast F, et al. - Researchers undertook this single center prospective, observational study to assess the link between a moderate to high risk patients of obstructive sleep apnea syndrome (OSAS) and postoperative cognitive dysfunction following volatile anesthesia. Participants were 46 patients aged 55 to 80 years with an estimated hospital stay of at least 3 days receiving surgery. Of 46 analyzed patients, 23 had a moderate to high risk of OSAS. Findings revealed improved postoperative cognitive function, measured by the DemTect test, in relation to a moderate to high risk of OSAS, than low risk, based on the STOP-BANG score (snoring, tired, observed, pressure, body mass index, age, neck size, gender).
