Background: Obstructive sleep apnea (OSA) is associated with increased risk of
postoperative complications. The authors investigated whether preoperative diagnosis and
prescription of continuous positive airway pressure therapy reduces these risks. Methods:
Matched cohort analysis of polysomnography data and Manitoban health administrative
data (1987 to 2008). Postoperative outcomes in adult OSA patients up to 5 yr before
(undiagnosed OSA, n= 1,571), and any time after (diagnosed OSA, n= 2,640) …

Mayo Clinic sought to establish whether preoperative statin therapy is associated with a
lower frequency of postoperative acute respiratory distress syndrome (ARDS) in surgical
populations at higher risk of developing ARDS. Hence, they performed a retrospective
cohort evaluation of the association between preoperative statin therapy and early
postoperative ARDS in patients having elective high-risk thoracic and aortic vascular
surgery. The association between preoperative statin treatment and postoperative ARDS …
