Reduction in emergency department (ED) overcrowding is a major Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) initiative. One major source of ED overcrowding is patients waiting for telemetry beds. ⋯ For patients admitted to the authors' institution with a potential acute coronary syndrome, there was no association between a negative evaluation for underlying coronary artery disease and overall or potentially cardiac ED visits, admissions, or cardiac resource test utilization over the year following the index visit.

In relying on the peripheral blood white blood cell (WBC) count to identify infants at high risk for acute bacterial meningitis and bacteremia, to the best of the authors' knowledge, it has not been reported previously whether high and low values of the test have similar implications for predicting these separate infections. ⋯ In young infants, the peripheral blood WBC count is useful for estimating the odds of acute bacterial meningitis relative to isolated bacteremia. A low peripheral blood WBC count should be considered a much more worrisome laboratory finding because it is associated with a relatively high risk for acute bacterial meningitis relative to the potential for bacteremia.

Studies of emergency department (ED) pain management in patients with trauma have been mostly restricted to patients with fractures, yet the potential for undertreatment of more severely injured patients is great. The authors sought to identify factors associated with failure to receive ED opioid administration in patients with acute trauma who subsequently required hospitalization. ⋯ Many trauma activation patients requiring hospitalization do not receive opioid analgesia in the ED. Patients at particular risk for oligoanalgesia include those who are younger or older and those who are more seriously injured, as defined by a lower Revised Trauma Score, lower Glasgow Coma Scale score, and intubation.

Comparative Study
Use of vasopressin in a canine model of severe verapamil poisoning: a preliminary descriptive study.
The purpose of this preliminary study was to evaluate the effect of arginine vasopressin (AVP) administration in a model of shock induced by calcium channel antagonist overdose and to determine endogenous serum AVP concentrations in calcium channel antagonist-induced shock. ⋯ In an animal model of verapamil-induced shock, endogenous AVP levels increased nearly 40-fold compared with baseline levels. Escalating doses of exogenous AVP worsened cardiac index and failed to return MAP to within 20% of baseline.
