07 / The influence of training experience on trainees’ self-assessment in cardiac anaesthesia: A 8-year retrospective exploratory evaluation.

Abstract

Materials and Methods:Sixteen PGY-1 anesthesia residents without USguided TAP block experience were randomized into two groups: the control group (C group) and the pork belly (PB group), each of eight. The training course consisted of two modules: a knowledge module and a second practice module. PowerPoint slides and videos were used to show (1) mechanism of sonography, (2) anatomy and sonoanatomy of TAP block, (3) and skills of hydro-dissection and image optimization in the knowledge module in both groups. In practice module, a blue phantom was used for practicing hand-eye coordination in the C group. In the PB group, a 20cm×30cm pork belly was used for practicing hand-eye coordination and hydrodissection. The practice module would not end until all trainees reached a mastery level. Skills of hand-eye coordination and hydro-dissection were tested respectively in a 20cm×30cm pork belly in both groups. Rates of mastery of hand-eye coordination and hydro-dissection were compared between the two groups using chi-square test. A P< 0.05 was considered as statistically significant.
