Brief Summary:

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.

Arm Intervention/treatment
Active Comparator: Conventional laryngeal handshake technique
The conventional laryngeal handshake technique is performed to localize the cricothyroid membrane
Procedure: Conventional laryngeal handshake technique
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.

Experimental: Modified laryngeal handshake technique
The modified laryngeal handshake is performed to localize the cricothyroid membrane
Procedure: Modified laryngeal handshake technique
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.




Primary Outcome Measures :
  1. The accuracy to localize the cricothyoid membrane [ Time Frame: 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 using ultrasound.


Secondary Outcome Measures :
  1. Time to localize the cricothyroid membrane [ Time Frame: through the identification of cricothyroid membrane, an average of 5 minutes ]
    The time taken to identify the cricothyroid membrane is recorded.
