Case ReportsObstructive sleep apnea syndrome: Anesthetic implications in the cardiac surgical patient*

Case reports
All 4 patients had a history of excessive daytime sleepiness, snoring, and apneic episodes and were diagnosed as OSAS on polysomnography. Age, weight, body mass index, chest radiograph finding, pulmonary function test, and Mallampati class of all 4 patients are represented in Table 1, and polysomnography results are shown for 2 patients in Table 2.Case Age (y) Sex Weight (kg) Height (m) BMI Preoperative Chest Film Preoperative PFT Study Disease Ejection Fraction (%) Mallampati Class 1 54 M 96 1.74
Discussion
With the growing awareness of the increased incidence of breathing disorders during sleep occurring among IHD patients, it is prudent for the anesthesiologist to probe into patients' sleeping habits. The severity of symptoms of OSAS increases with age and obesity, common symptoms being excessive daytime sleepiness, loud snoring followed by apnea, and transient wakefulness associated with an inability to recall the arousal events. Patients suffering from sleep-disordered breathing are evaluated
