Trauma care delivery in Canada, even in major trauma centers, usually devolves to the most involved service. For patients with multisystem injuries, this is not always optimal and aspects of care outside the domain of the primary service are apt to be overlooked. Trauma care is necessarily multidisciplinary, and to be optimal, appropriate integration of the care process and prioritization are required. The purpose of this study was to examine the impact on care in a busy provincial trauma center, after the introduction of a trauma program with a clinical trauma service, revised trauma protocols, and a dedicated trauma unit. ⋯ Trauma care improvement can be achieved by a multidisciplinary team focusing on the process of care, developing a dedicated trauma service to manage the more seriously injured patients, collecting them onto a single unit, and initiating program management.

The optimal method of evaluating blunt abdominal trauma remains controversial. A combination of a sensitive screening test, diagnostic peritoneal lavage (DPL), and a specific test, abdominal computed tomography (CT), may be a safe, efficient approach to adult blunt abdominal trauma. ⋯ Screening DPL, followed by abdominal CT if positive, is a safe, efficient method of evaluating adult blunt abdominal trauma that reduces the time required to evaluate the abdomen, does not result in increased nontherapeutic celiotomies, results in fewer missed injuries, and reduces the overall use of abdominal CT.

Hemorrhagic shock is associated with lactic acidosis and increased plasma catecholamines. Skeletal muscle increases lactate production under aerobic conditions in response to epinephrine, and this effect is blocked by ouabain, a specific inhibitor of the cell membrane Na+/K+ pump. In this study, we tested whether adrenergic antagonists can block lactate production during shock. ⋯ Epinephrine release in response to hypotension is a primary stimulus for muscle lactate production in this model of hemorrhagic shock. Hypoxia alone does not explain the increased lactate levels because tissue perfusion was not altered by the adrenergic antagonists. These observations challenge the rationale behind lactate clearance as an end point for resuscitation after hemorrhagic shock.

Trauma registries frequently do not include the deaths of patients who do not get to trauma centers (TCs). Thus, complementary methods of monitoring the impact of trauma system initiatives should be considered. The objective of this study is to use National Highway Safety Traffic Administration's Fatality Analysis Reporting System (FARS) and New York State Department of Motor Vehicles data and to study the impact of state and regional initiatives over a 10-year period in the seven-county Hudson Valley New York (HV) region with one regional TC in Westchester County (WC) and to assess its face validity. ⋯ The drops in motor vehicle crash death rates may reflect injury prevention as well as trauma system initiatives. Thus, although FARS and New York State Department of Motor Vehicles data cannot establish cause and effect relationships, it can monitor the aggregated impact of multiple initiatives. Taken together with increasing percentages of seriously injured trauma patients going to trauma centers and comparisons with national FARS data, the association of decreasing deaths with the implementation of a trauma system seems to have face validity.

The insertion of a chest drain into the pleural space is a common procedure used for treatment in various intrathoracic abnormalities. Recently, a new technique for chest-tube insertion for pleural cavity drainage, using the disposable endoscopic trocar-cannula, was described for the treatment of some pathologic conditions. ⋯ The use of endoscopic trocar-cannulae for chest-tube insertion is a safe, simple, and effective technique for management of trauma and other diverse intrathoracic abnormalities. Its use outside the hospital should be further studied.
