OBJECTIVES To 1) review the existing evidence for early mobilization of the critically ill patients in the ICU with polytrauma; 2) provide intensivists with an introduction to the biomechanics, physiology, and nomenclature of injuries; 3) summarize the evidence for early mobilization in each anatomic area; and 4) provide recommendations for the mobilization(More)
BACKGROUND Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David(More)
BACKGROUND Hemorrhage is a leading cause of death in trauma patients and coagulopathy is a significant contributor. Although the exact mechanisms of trauma-associated coagulopathy (TAC) are incompletely understood, hemostatic resuscitation strategies have been developed to treat TAC. Our study sought to identify which trauma patients develop TAC and the(More)
BACKGROUND Approximately 5% of blunt abdominal trauma patients experience blunt bowel and mesenteric injuries (BBMIs). The diagnosis may be elusive as computed tomography (CT) can occasionally miss these injuries. Recent advancements in CT technology, however, may improve detection rates. This study will assess the false-negative rate of BBMI using a(More)
BACKGROUND Haemorrhage in peripheral vascular injuries may cause life-threatening exsanguination. Tourniquets are used extensively by the military, with increased interest in the civilian setting to prevent deaths. This is a retrospective study of trauma patients at two large Canadian trauma centres with arterial injury after isolated extremity trauma. We(More)
BACKGROUND Emergency department (ED) thoracotomy can be lifesaving. It can also lead to resource waste and exposure to blood-borne infections. We investigated the frequency with which ED thoracotomy was performed for inappropriate indications and the resulting societal costs. STUDY DESIGN This retrospective cohort study examined all trauma patients(More)
A very unusual pattern of organic acid excretion was established in the urine of two premature newborns with severe respiratory distress and cerebral haemorrhages. By combined gas chromatography/mass spectrometry the following acids were identified: lactic acid, α-hydroxy-butyric acid, β-hydroxy-butyric acid, α-hydroxy-isovaleric acid, and(More)
OBJECTIVE To evaluate the implementation of an all-inclusive philosophy of trauma care in a large Canadian province. BACKGROUND Challenges to regionalized trauma care may occur where transport distances to level I trauma centers are substantial and few level I centers exist. In 2008, we modified our predominantly regionalized model to an all-inclusive one(More)
Tracheostomy is a common surgical procedure, and is increasingly performed in the intensive care unit (ICU) as opposed to the operating room. Procedural knowledge is essential and is therefore outlined in this review. We also review several high-quality studies comparing percutaneous dilational tracheostomy and open surgical tracheostomy. The percutaneous(More)
