  Objective: To investigate the effects of 400 mg of caffeine ingestion on previously untrained students’ performance on simulated microsurgical tasks. Methods: 10 previously untrained students were included and randomised into two groups: a control or caffeine group. Each group received a 15-min orientation session on a microsurgical simulator (VRMagic eyesi surgical simulator, Mannheim, Germany). Each group then performed three repetitions of each task: a navigation task, a forceps task and a bimanual task. The control group repeated the testing sequence after a 30-min break. The caffeine group orally ingested 400 mg of caffeine and 30 min later repeated the same sequence. An ECG was performed on the caffeine group before and after caffeine ingestion to assess for arrhythmia. Overall score (%) was the primary outcome. Secondary outcomes i.. View More»
