To determine the incidence of alcohol use in subcritically injured patients presenting to the ED, by using a saliva alcohol test (SAT) at ED triage during the ED initial assessment; to compare the incidence of alcohol use revealed by the SAT with documentation of alcohol use by ED nurses and emergency physicians (EPs) blinded to the SAT results; and to describe the demographics of the SAT-positive, subcritically injured population. ⋯ While the SAT identified 21% of the subcritically injured patient population as alcohol-positive, ED nurse and EP documentation did not identify half of these alcohol-positive patients. Many of these patients may be at risk for additional injuries related to their drinking behavior.

To measure agreement beyond chance (kappa) for comparison interpretations of extremity radiographs by pediatric radiologists and emergency physicians (EPs) and to identify factors associated with disagreement. ⋯ There is good agreement between EPs and pediatric radiologists in interpreting extremity radiographs of injured children and adolescents. Disagreement occurs mainly for effusions or minor fractures and for the elbow region. Because of the importance of recognizing abnormalities in this region, an educational intervention to improve this area of deficiency is recommended.

To assess the risk of hemolysis, disseminated intravascular coagulation (DIC), or fat embolism syndrome (FES) with pressurized intraosseous (IO) blood transfusion following hemorrhage. ⋯ In this model, pressurized IO blood transfusion appears to be hematologically safe, i.e., without risk of appreciable hemolysis, DIC, or FES.

Chest compression and ventilation rates during cardiopulmonary resuscitation: the effects of audible tone guidance.
To determine: 1) whether chest compressions during CPR are being performed according to American Heart Association (AHA) guidelines during cardiac arrest; and 2) the effect of an audio prompt to guide chest compressions on compliance with AHA guidelines and hemodynamic parameters associated with successful resuscitation. ⋯ The majority of Basic Cardiac Life Support--certified health care professionals did not perform CPR according to AHA-recommended guidelines. The use of audible tones to guide chest compression resulted in significantly higher chest compression rates and ETCO2 levels.

A previously healthy 32-year-old man presented to the ED in complete heart block. Ischemic, infectious, and inflammatory conditions were considered in the differential diagnosis. Management options for complete heart block, the etiology of heart block in young adults, and treatment guidelines are reviewed.
