Abstract
BACKGROUND: The latest Difficult Airway Society (DAS) guidelines recommend that all anaesthesiologists should to be trained in the performing of a surgical cricothyrotomy (CtQ). The aim of this study was to analyse the learning results of a CtQ workshop by assessing the success rate and time to perform CtQ on a porcine tracheal model.
MATERIAL AND METHODS: A workshop was designed in which each student completed a questionnaire with demographic data and theoretical knowledge about surgical approaches of airway. During the following hour, a review was presented theoretical aspects of CtQ. The model was shown and a CtQ was performed using a classical technique. Afterwards, in groups of 3-4 students with an instructor, each one of the students performed 6 CtQ. A record was made on whether the ventilation was correct, the time to perform CtQ, and the ease of performing the CtQ by the students and instructors. Finally, students completed a questionnaire on the theoretical aspects. Students and instructors performed a workshop debriefing. A statistical analysis was performed, considering a P-value <0.05 as statistically significant.
RESULTS: A total of 8 workshop sessions were held with a total of 91 students. At first attempt, 86% of students performed a CtQ with successful ventilation, and 92% at the sixth attempt (P<.0001). Time taken was 163 [107-211] seconds at first attempt, and 70 [55-85] seconds at the sixth (P<.0001). At the end of workshop, students had improved their theoretical knowledge (P<.0001) and perception of the ease of the technique.
CONCLUSION: Workshop performance improved theoretical knowledge and competence in surgical cricothyrotomy.
