What this study is about

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.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Primary outcomes

Adequate Bag-Mask VentilationOnly once, after giving general anesthesia but before an endotracheal tube is put in the trachea

When an anesthetized patient is being manually ventilated by an anesthesia bag and a face mask and achieving a tidal volume of 5 ml/kg, it will be called adequate mask ventilation. * Easy if a single anesthesiologist achieves visible adequate chest rise and an end-tidal CO₂ graph. * Moderately difficult, if there is a slight chest rise, a low end-tidal CO₂ graph, but peripheral oxygen saturation is maintained above 97%. * Difficult if there is no visible chest rise, minimal or no end-tidal CO₂ graph, or if peripheral oxygen saturation drops to less than 95% but becomes normal with use of an oral airway (Guedel airway) or a laryngeal mask airway (LMA), or if two anesthesia providers are required for adequate mask ventilation. * Very difficult if peripheral oxygen saturation drops to 90% or less despite the use of airway adjuncts (Guedel airway or LMA).

Difficult Tracheal IntubationOnly once, after giving general anesthesia and 3-minute bag-mask ventilation for adequate muscle relaxation effect, then direct laryngoscopy will be performed to put the endotracheal tube in the trachea

Difficult tracheal intubation will be defined as, one that requires external laryngeal manipulation, laryngoscopy requiring more than 3 attempts at intubation, intubation requiring nonstandard equipment or approaches, or the inability to intubate at all
