Cardiovascular and Diving-Related Complications

To determine whether high risk scores on preoperative STOP-BANG (Snoring, Tiredness during daytime, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, Gender) questionnaires during preoperative evaluation correlated with a higher rate of complications of obstructive sleep apnea syndrome (OSAS).Historical cohort study.Thomas Jefferson University Hospital, Philadelphia, Pennsylvania.Adult patients undergoing elective surgery at a tertiary care center who were administered the STOP-BANG questionnaire for 3 consecutive days in May 2008.Number and types of complications.A total of 135 patients were included in the study, of whom 56 (41.5%) had high risk scores for OSAS. The mean (SD) age of patients was 57.9 (14.4) years; 60 (44.4%) were men. Patients at high risk of OSAS had a higher rate of postoperative complications compared with patients at low risk (19.6% vs 1.3%; P < .001). Age, American Society of Anesthesiologists class of 3 or higher, and obesity were associated with an increased risk of postoperative complications. On multivariate analysis, high risk of OSAS and American Society of Anesthesiologists class 3 or higher were associated with higher odds of complications.The STOP-BANG questionnaire is useful for preoperative identification of patients at higher than normal risk for surgical complications, probably because it identifies patients with occult OSAS.
