Clinical Trial Controlled Clinical Trial
Effect of the Advanced Trauma Life Support program on medical students' performance in simulated trauma patient management.
Part of the senior medical students' examination at the University of Toronto involves testing with simulated patient management. We compared the performance in these simulations of senior medical students who received Advanced Trauma Life Support (ATLS) training with those who did not receive ATLS training. ⋯ The ATLS course, both complete and audit status, prepares students more appropriately for managing trauma patients as judged by trauma simulation scenarios. Consideration should be given for including ATLS as an integral part of the senior medical student curriculum.

To examine the psychosocial adjustment of survivors of massive pediatric burn injuries, the change in adjustment across time, and the impact on parents. ⋯ Children who survive massive burn injuries can achieve positive psychosocial adaptation.

Abdominal computed tomographic (CT) scans are used in the evaluation of blunt trauma. The purpose of this study was to determine if isolated intraperitoneal fluid seen on CT scan necessitates laparotomy. ⋯ Exploratory laparotomy was therapeutic in 94% of patients. Isolated intraperitoneal fluid on CT scan after blunt trauma mandates laparotomy.

Ongoing clinical trials have revived interest in hypertonic saline (HTS) for postinjury resuscitation; these studies have documented serum Na+ concentrations > or = 170 mmol/L. Recent animal studies have shown that HTS enhances T-cell and monocyte function, but effects on the polymorphonuclear neutrophil (PMN) remain unclear. The postinjury lipid mediators platelet-activating factor (PAF) and leukotriene B4 (LTB4) have been implicated in PMN priming for cytotoxicity, which is believed to be important in the pathogenesis of multiple organ failure. We hypothesized that HTS would stimulate PMN superoxide (O2-) and elastase release from PAF- and LTB4-primed PMNs. ⋯ In clinically relevant concentrations, elevated Na+ activates lipid-primed neutrophils for enhanced elastase degranulation. Consequently, the administration of HTS in the early postinjury resuscitation period, when PMNs are maximally primed, may activate PMN elastase release and thereby promote the development of multiple organ failure.

The Injury Severity Score (ISS) does not take into account multiple injuries in the same body region, whereas a New ISS (NISS) may provide a more accurate measure of trauma severity by considering the patient's three greatest injuries regardless of body region. The purpose of this study was to evaluate the ISS and NISS in patients with blunt trauma. ⋯ The NISS often increases the apparent severity of injury and provides a more accurate prediction of short-term mortality. The benefit associated with using the NISS rather than the ISS must be weighed against the disadvantages of changing a scoring system and the potential for still greater improvements.
