简要总结
Cricothyroidotomy is an emergency rescue technique to secure the airway in a 'Can't intubate, Can't Oxygenate' (CICO) situation. The cricothyroid membrane (CTM) is the target site of cricothyroidotomy, and accurate identification of the CTM is essential for successful cricothyroidotomy. In this study, the investigators compare patient positions (neck extension vs. modified ramped position) in terms of the success rate for identifying the CTM in obese patients.

结局指标
主要结局
Success rate for the correct identification of the cricothyroid membrane
时间窗: Immediately after identifying the cricothyroid membrane using a laryngeal handshake technique
After identifying the cricothyroid membrane using a laryngeal handshake technique in different head positions, an assessor evaluates the correctness of its localization using ultrasound.
次要结局
- Duration for identifying the cricothyroid membrane(At 90 seconds after administering neuromuscular blockade)
- Perceived difficulty during cricothyroid membrane identification(At 5 minutes after identifying the cricothyroid membrane using a laryngeal handshake technique)
- Distances between the center of the actual and perceived cricothyroid membrane(Immediately after identifying the cricothyroid membrane using a laryngeal handshake technique)
