Abstract

Abstract: Objective To evaluate the effectiveness of simulation-based training in the ultrasound-guided regional anesthesia teaching program. Methods This prospective assessor-blind randomly controlled trial was conducted in the hospital from November 2019 to October 2020. Thirty anesthesia trainees from clinical rotation program of anesthesiology residence training project were randomly divided into workshop group (WG) or the control group (CG) for pre-technical procedure training on UGRA. Following didactic lectures, simulation-based workshops were performed only for the WG. All trainees were assessed by written examination, ultrasound scanning and anatomy recognition in human body and ultrasound-guided target injections into pork mass. The scores of examination, drawing anatomy, the sonographic proficiency ,nerve recognition and the time taken to perform the injections as well as the errors were all recorded and analyzed. Difference of measurement data was compared by t-test or rank-sum test. Results The simulation-based training program significantly decreases the time taken for target injections in the WG as compared with that in the CG [188.0(53.5) s vs. 219.0(70.5) s, P=0.006]. The total errors score was lower in WG than in CG [5.5(4.5) vs. 10.0 (8.5), P=0.001]. The drawing anatomy score (33.8±5.4 vs. 28.5±6.1), sonographic proficiency score (37.8±5.9 vs. 24.5±7.4) and the nerve recognition score (7.1±1.9 vs. 4.6±2.3) were all higher in the WG than that in the CG (all P<0.05). Conclusions For anesthesia trainees, the simulation-based training program can improve the UGRA skills and support the building of clinical competence.
