A concern on the level of anatomy knowledge reached after a problem-based learning curriculum has been documented in the literature. Spatial anatomy, arguably the highest level in anatomy knowledge, has been related to spatial abilities. Our first objective was to test the hypothesis that residents are interested in a course of applied anatomy afte...

Traumatic cardiac valve injury caused by stabbing and gunshot wounds is a rare event and is usually associated with complex cardiac lesions and pericardial tamponade. We report one case of isolated laceration with almost complete longitudinal division of the posteromedial papillary muscle of mitral valve as a result of stab wound. To our knowledge,...

Purpose To compensate for the shortage of emergency specialists and to maintain quality of medical care in remote regions. Methods Develop and validate the concept of real-time coaching using a robotized camera system ceiling-mounted above a stretcher. Exploit a final prototype to evaluate its impact on surgical procedures under controlled conditio...

To compensate for the shortage of emergency specialists and maintain quality of medical care in remote regions, this paper presents two robotic systems enabling real-time telecoaching on surgical procedures in emergency rooms. The first one uses two robotized cameras moving on rails mounted on the ceiling and perpendicular to the stretcher. Cricoth...

Isolate and evaluate the impact of mental imagery on the acquisition of an emergency surgical technique. We studied 44 first-year medical students performing a cricothyrotomy on a mannequin to determine the impact of teaching using mental imagery (MI) and/or kinesiology (KG) compared to the standard Advandec Trauma Life Support (ATLS) approach. Stu...

Introduction: We verified the value of cognitive task analysis and kinesiology in the teaching of basic surgical skills. Furthermore we wanted to identify the role of mental imagery in the acquisition and retention of surgical skills particularly for an emergency procedure seldom done in routine practice (cricothyroidotomy). Methods: We randomly di...

This study aimed to determine the impact of warfarin use on the severity of injury among elderly patients presenting with closed head injuries. A cohort of patients 55 years of age or older with closed head injuries taken to a tertiary trauma center between April 1993 and March 2001 was retrospectively identified. Patient characteristics, mechanism...

Complications after procedures performed by residents are thought to occur most often early in the first postgraduate year (PGY-1). We evaluated the number of pneumothoraces (PTXs) caused by central venous line insertion (CVLI) by two groups of PGY-1 residents in both the first 3 months of residency and the entire year from 1996 through 2000 to det...

The purpose of this study was to show that elderly patients admitted with rib fractures after blunt trauma have increased mortality. Demographic, injury severity, and outcome data on a cohort of consecutive adult trauma admissions with rib fractures to a tertiary care trauma center from April 1, 1993, to March 31, 2000, were extracted from our trau...

Objective: The purpose of this study was to show that systematic screening after blunt head trauma can identify patients with previously unsuspected minor closed head injuries which require further treatment. Patients and Methods: All trauma patients reporting to the emergency department of a regional trauma center following blunt trauma, from Apri...

The purpose of this study was to show that blunt diaphragmatic rupture does not require immediate emergency operation in the absence of other indications. We reviewed all patients with blunt diaphragmatic rupture admitted within 24 hours of injury to one of six university trauma centers providing trauma care for the province of Quebec from April 1,...

Between 1 June 1993 and 31 December 1998, 17 patients underwent temporary abdominal closure with 3L urological irrigation bags, because in most cases, there was massive sepsis leading to the conclusion that primary closure was not advisable. Indicative of the seriousness of these conditions, Apache score averaged 19 (range 10-30). The technique con...
