HealthDay (9/27, Preidt, 5K) reported that, according to a 4,200-patient study published in the October issue of the journal Anesthesiology, “screening and treating patients for obstructive sleep apnea [OSA] before they have surgery may reduce their risk of cardiovascular complications by more than half.” The study revealed that “patients with untreated sleep apnea were at increased risk for cardiovascular complications such as cardiac arrest or shock, while those who began CPAP therapy before surgery were less than half as likely to develop such complications.” In addition, “patients with sleep apnea were twice as likely to have surgery-related respiratory complications as those without sleep apnea, and that the airway pressure therapy did not reduce that risk,” researchers found.
