A Simple Model to Increase Residents' Confidence in Emergency Front of Neck Access (eFONA).

Emergency front of neck access (eFONA) in a non-ventilated, non-oxygenated (CVCO) patient scenario is a life-saving and important competency for anesthesiologists to learn and even repeat intermittently. The Difficult Airway Society (DAS) guideline does not elaborate on how to conduct eFONA training, while the Canadian guideline states that successful performance of such rarely used skills requires regular practice in a simulation environment that focuses on technique and provides expert feedback. In this guideline, it was also mentioned that during training, procedures can be repeatedly performed in a simulate environment and interrupted for immediate feedback. In line with these recommendations, the investigators will create an easy, inexpensive, feasible and repeatable simulation-based learning environment in the operating room of the hospital. In this model study, it is aimed to teach the cricothyrotomy technique to anesthesiologists who have no experience in eFONA with an easy set up and to increase the confidence of the participants in this subject.

Participants will be divided into groups according to their duration of anesthesiology residency: 1st year, 2nd year, 3rd year, 4th and 5th year residents. A simple surgical airway delivery model will be created from the unused anesthesia circuit. The model will be described to the participants and anatomical markers will be explained: hyoid bone, thyroid cartilage, cricoid cartilage, cricothyroid membrane, tracheal rings. Then the algorithm in the DAS guidelines will be explained. Following this, the researcher will demonstrate the scalpel spark plug technique with a 4-step approach that is frequently used in skill teaching (4).

In step 1 of this approach, the technique will be demonstrated without any verbal explanation.

In the 2nd step, the technique will be demonstrated with verbal expression. In the 3rd step, the participant will be asked to have the trainer do it. In the 4th and last step, the participant will apply eFONA from start to finish.

Participants will apply all the steps on the model until they feel competent, then when the participants are ready, they will be asked to perform the technique by keeping a stopwatch. The stopwatch will be started when the participant takes the scalpel in his/her hand.
