USG Vs Palpation for Cricothyroid Membrane Determination

Recruiting

• Conditions: Cricothyroid Membrane; Ultrasound

• Registration Number: NCT05974540
• Lead Sponsor: Marmara University

Brief Summary

Emergency cricothyroidotomy is a very important technique to ensure airway safety in acute situations. Problem in identifying the cricothyroid membrane is a major contributor to high failure, as the most common complication during cricothyrotomy is the misplacement of the cannula. The success rate of emergency airway access performed by anesthesiologists and emergency medicine specialists was found to be low due to the low frequency of the procedure. The aim in this study is to compare the palpation method with the ultrasonugraphy (USG)-based method in determining the cricothyroid membrane. The hypothesis is that USG is more successful than palpation in identifying the cricothyroid membrane. In addition, the relationship between difficult intubation and measurements such as the cricothyroid membrane length, the cricoid cartilage and the skin distance, the distance between the cricoid cartilage and the second tracheal ring will be evaluated.

Primary Outcome Measures

Name	Time	Method
Distance between palpation-based and USG-based determination of the cricothyroid membrane	On the 1 day of the surgery. After the anesthesia induction and intubation.	Regarding the determination point of the cricothyroid membrane the distance between palpation-based method performed by pediatric surgeon and USG-based method performed by anesthesiologist will be measured.

Secondary Outcome Measures

Name	Time	Method
Cricothyroid membrane length	On the 1 day of the surgery. After the anesthesia induction and intubation.	Cricothyroid membrane length will be measured by anesthesiologist using USG. Longitudinal view of the thyroid, cricoid and trakeal ring cartilages will be obtained and the measurement will be made.
Skin distance from cricoid cartilage	On the 1 day of the surgery. After the anesthesia induction and intubation.	Skin distance from cricoid cartilage will be measured by anesthesiologist using USG. Longitudinal view of the thyroid, cricoid and trakeal ring cartilages will be obtained and the measurement will be made.
Distance between cricoid cartilage and 2nd tracheal ring	On the 1 day of the surgery. After the anesthesia induction and intubation.	Distance between cricoid cartilage and 2nd tracheal ring will be measured by anesthesiologist using USG. Longitudinal view of the thyroid, cricoid and trakeal ring cartilages will be obtained and the measurement will be made.
