Alexa A, et al. - In this retrospective review of postoperative course of patients who had primary (idiopathic) central sleep apnea (PCSA) and underwent procedures requiring anesthetic management at researchers' institution, the focus was to identify respiratory complications. No major adverse outcomes were found to be associated with PCSA postoperatively. Of 10 patients (nine males, one female) who underwent 47 procedures requiring anesthetic management, second-degree heart block in one patient and pneumonia in another two complicated the procedures. In one patient who had cirrhosis and postoperative hypoxemia, the utility of continuing home positive airway pressure therapy during anesthesia recovery was demonstrated.
