Visuospatial Ability as a Predictor of Novice Performance in Ultrasound-guided Regional Anesthesia.

摘要: Background: Visuospatial ability correlates positively with novice performance of simple laparoscopic tasks. The aims this study were to identify if visuospatial could predict technical an ultrasound–guided needle task by operators, and describe how emotional state, intelligence fear failure impact on this. Methods: Sixty medical student volunteers enrolled in observational study. We used instructional video standardize training for ultrasound-guided advancement a turkey breast model assessed volunteers’ independently two assessors using composite error score (CES) global rating scale (GRS). their ‘visuospatial ability’ mental rotation test (MRT), group embedded figures (GEFT) Alice Heim (AH4) test. ‘Emotional state’ was judged UWIST mood adjective checklist (UMACL) failure, ‘general cognitive numerical reasoning (NRT-20). Results: High CES scores (high rate) associated low MRT (= −0.54; P<0.001). Better GRS better 0.47; Regarding emotions, when anxiety levels high −0.35; P= 0.005) (errors) individuals reported feeling vigorous active −0.30; 0.01). Conclusions: predicts needling model, as trait measure be tool focus resources less able individuals. Anxiety adversely affects performance. Both may therefore prove useful directing targeted USGRA.
