简要总结
In this study, we compare the conventional laryngeal handshake technique and modified laryngeal handshake technique for locating the cricothyroid membrane in terms of accuracy and speed. The conventional laryngeal handshake technique is performed with the non-dominant hand, identifying the hyoid bone and thyroid laminae, stabilizing the larynx between thumb and middle finger, and moving down the neck to palpate the cricothyroid membrane with the index finger.
The modified laryngeal handshake is performed with the non-dominant hand, stabilizing the trachea between thumb and middle finger from the suprasternal notch and moving up the neck to palate the cricoid cartilage and cricothyroid membrane with the index finger.

结局指标
主要结局
The accuracy to localize the cricothyoid membrane
时间窗: 1 minute after identifying the cricothyroid membrane using the conventional or modified laryngeal handshake technique
The accuracy of the cricothyroid membrane identified by the conventional and modified handshake techniques are evaluated.
次要结局
- Time to localize the cricothyroid membrane(through the identification of cricothyroid membrane, an average of 5 minutes)
- The accuracy to localize the midline of the neck(through the identification of cricothyroid membrane, an average of 5 minutes)
- The vertical and horizontal distances between the actual and perceived cricothyroid membrane(through the identification of cricothyroid membrane, an average of 5 minutes)
