IntroductionUnsuccessful tracheal intubation is considered the most common cause of anesthesia death or brain damage. This study delineates our experience recommending modifications in the cricothyroidotomy technique.MethodsThirty emergency medicine residents of participated in a study performed on the human simulator moulage in Skill Laboratory of Tabriz University of Medical Science. The cricothyroid membrane was punctured using a 16-gauge cannula. Later, J guide wire was advanced into trachea and standard 16-gauge intravenous cannula with a removable needle stylet withdrawn after the puncture being dilated by a dilator. Consequently, a cuffed tracheal tube (ID= 6) was introduced from the foramen.ResultsFrom 30 residents, 18 residents performed cricothyroidotomy within 1 minute, 7 residents in 2 minutes and 5 residents failed to fulfill the procedure.ConclusionSeveral studies using cadavers and human simulators have demonstrated the pre-hospital feasibility of this technique. However, descriptions of clinical pre-hospital experience with percutaneous cricothyroidotomy are limited. This study shows that skill lab may help residents to acquire techniques required in management of difficult airway.
