Filter by: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.
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.
Cricothyroid membrane (CTM) localization is a critical step prior to emergent surgical airway access. Ultrasound-guided localization of the CTM on the skin of the neck had been suggested prior to induction of general anesthesia so that a marked entry point can be used to quickly establish emergent front of neck access if required. In this prospective observational study, the investigators aim to determine the potential for migration of the CTM markings in the sagittal plane during neck repositioning.
