Visuospatial ability and novice brachial plexus sonography performance.

摘要: BACKGROUND The knowledge on the type and influence of visuospatial ability sonography performance relevant for ultrasound-guided regional anaesthesia remains incomplete. aim this study was to determine whether four different factors are important in determining proficiency procedure time novices performing brachial plexus sonography. These were spatial visualisation, flexibility closure, relations speed closure. METHODS Thirty-three ultrasound recruited prospective, observational trial. Five cognitive tests, from a standardised battery that assesses all factors, administered each participant at start study. Each novice then performed human model baseline final exams, separated by discovery learning session. Novices examined their blinded assessors who scored proficiency, technique, image quality, taken perform both scans. RESULTS with intermediate high closure significantly more proficient efficient compared peers stratified into low-ability cohorts (P < 0.02). Matrix Reasoning Mental Rotations Test-A correlated exam scores (Spearman rank correlation ρ = 0.38 0.36, P 0.03 0.04, respectively). CONCLUSIONS Spatial but not performance. Visuospatial testing can identify will require extra assistance anaesthesia. ( TRIAL REGISTRATION Australian New Zealand Clinical Trials Registry 12614000819628).
