Using the STOP-BANG questionnaire to predict obstructive sleep apnea and difficult intubation in thoracic surgery patients

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

Observational Atatürk Chest Diseases and Chest Surgery Training and Research Hospital · NCT06247631

This study is testing if the STOP-BANG questionnaire can help predict sleep apnea and difficult intubation in patients aged 18-65 who are having thoracic surgery.

What this trial studies

This observational study aims to evaluate the effectiveness of the STOP-BANG questionnaire as a screening tool for obstructive sleep apnea syndrome (OSAS) in patients undergoing thoracic surgery. It investigates how well this questionnaire can predict the likelihood of difficult mask ventilation and intubation, which are critical factors in anesthesia management. By focusing on patients aged 18-65 with an ASA classification of 1-3, the study seeks to enhance preoperative assessments and improve patient safety during surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 18-65 undergoing thoracic surgery with an ASA classification of 1-3.

Not a fit: Patients with a history of obstructive sleep apnea syndrome or previous head and neck surgery/radiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better identification of patients at risk for difficult airway management, ultimately improving surgical outcomes and patient safety.

How similar studies have performed: While the STOP-BANG questionnaire has been widely used in various settings, this specific application in predicting difficult intubation during thoracic surgery is relatively novel.
