Difficult Airway Prediction by Integrating STOP-BANG Criteria
Enhancing Difficult Airway Prediction in Obese Patients: Integrating STOP-BANG With Additional Airway Assessment Tools
Source: ClinicalTrials.gov · Last updated 25 Mar 2026
Brief summary (registry, in English)
This study is being done to determine the diagnostic accuracy of the STOP-BANG questionnaire in predicting difficult mask ventilation and intubation among obese patients. During the preoperative assessment, eligible participants will be enrolled in the study. The modified Mallampati score, thyromental distance, mouth opening, and upper lip bite tests will be performed along with STOP-Bang scores. Later in the operating room, general anesthesia will be given, and bag-mask ventilation and intubation grade will be assessed and recorded. A correlation will be assessed between the difficult airway assessment findings, along with the STOP-BANG score and the bas-mask difficulty scores and intubation grades.
