Abstract
BACKGROUND: The time and conditions may not be suitable for performing polysomnography (PSG) before urgent or emergent surgeries, for example, a coronary artery bypass graft. Unavailability in many centers, critical clinical situation, and inability to arrange a timely scheduled appointment are other limitations for PSG. In this study, we aimed to investigate if the STOPBANG Questionnaire may predict obstructive sleep apnea syndrome (OSAS) related postoperative pulmonary alterations during coronary artery surgery.
METHODS: Sixty-one subjects who were scheduled to undergo elective isolated coronary artery bypass graft surgery and were consulted for preoperative pulmonary assessment were recruited to the study. The STOP-BANG Questionnaire was used with the subjects; then their relationship with postoperative complications was assessed.
RESULTS: Results of the STOP-BANG Questionnaire revealed that 36.1% of subjects were at high risk for OSAS. Three groups were established according to the STOP-BANG Questionnaire (low risk, group 1; moderate risk, group 2; high risk, group 3) and study parameters, including PEEP value in ventilator, detection of apnea at ventilator, CPAP time after extubation, SpO2 1 h after extubation, postoperative hypoxemia, need for CPAP, and ICU length of stay revealed significant relationships among these groups.
CONCLUSIONS: The STOP-BANG Questionnaire may predict the OSAS risk and OSAS-related pulmonary complications for patients who are candidates for a coronary artery bypass graft and unable to be evaluated with PSG before surgery due to technical or time-related limitations.
