STOP-Bang Questionnaire: a Predictor of Obstructive Sleep Apnea and Difficult Mask/intubation?

Can the STOP-Bang Questionnaire Predict Obstructive Sleep Apnea and Difficult Mask/intubation in Patients Scheduled for Thoracic Surgery? Prospective Observational Study

Difficult airway management remains the leading cause of anaesthesia-related morbidity and mortality. Obstructive sleep apnea syndrome (OSAS) is a warning sign of difficult airway management. Polysomnography is the gold standard for diagnosis of this syndrome, but the STOP-BANG questionnaire is the preferred screening test. In this study, we wanted to find an answer to the question How successful is the STOP-BANG questionnaire in screening for obstructive sleep apnea syndrome (OSAS) in predicting OSAS, difficult mask and difficult intubation in patients undergoing thoracic surgery?

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Control; Easy airway: unassisted mask ventilation, ventilation without the need for an airway, achieving oxygen saturation above 90% during mask ventilation, and unassisted intubation with less than three attempts.	Other: STOP BANG; The STOP-Bang Questionnaire is intended to give physicians an easy-to-use tool to identify people who might have obstructive sleep apnea (OSA). The questionnaire consists of eight yes-or-no questions based on the major risk factors for OSA. A STOP-Bang score of 2 or less is considered low risk, and a score of 5 or more is high risk for having either moderate or severe OSA. For people who score 3 or 4, doctors may need to perform further assessment to determine how likely they are to have OSA.; Other Names: STOP-Bang Questionnaire
Difficult airway; Difficult airway: assisted mask ventilation, need for airway during ventilation, oxygen saturation falling below 90% during mask ventilation, assisted intubation, intubation attempt three and above	Other: STOP BANG; The STOP-Bang Questionnaire is intended to give physicians an easy-to-use tool to identify people who might have obstructive sleep apnea (OSA).
