What the trial wants to find out

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?

The 2 groups in the trial

• 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.

  Treatment: STOP BANG

• 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

  Treatment: STOP BANG
