INTRODUCTION The Department of Surgery at the University of Arizona has created an intensive laparoscopic training course for surgical residents featuring a combined simulation laboratory and live swine model. We herein report the essential components to design and implement a rigorous training course for developing laparoscopic skills in surgical(More)
The goal of this study was to determine whether video laryngoscopy (VL) provides any advantage over direct laryngoscopy (DL) in first-attempt intubations. This was a controlled, randomized study of 120 medical students. Students were randomly assigned to either of 2 intubation groups, which used (1) DL (n=64) or (2) VL (n=56) with the Karl Storz C-MAC®(More)
Introduction: The objective of this study was to determine whether or not a navigation pointer (NP) integrated into a laparoscopic camera and projected onto a surgical display might allow instructors to more easily and precisely direct assistants' instruments to specific sites in a simulated laparoscopic field. Methods: Two hundred forty pins served as(More)
INTRODUCTION The objective of this study was to determine whether or not a navigation grid (NG) with a coordinate system overlaid on a laparoscopic display might allow attending surgeons to more easily and precisely direct their assistants' instruments to specific sites in a simulated laparoscopic field. MATERIALS AND METHODS In this randomized, crossover(More)
The objective of this study was to determine whether or not a standard definition stereoscopic, 3D display could improve trainees' performance on a standard Fundamentals of Laparoscopy (FLS) task. Thirty-two procedurally naïve volunteers were recruited for the study. Subjects were randomized to begin the trials on either the 3D or 2D display and performed(More)
