Bedside ultrasound examination by emergency physicians (EPs) is being integrated into clinical emergency practice, yet minimum training requirements have not been well defined or evaluated. This study evaluated the accuracy of EP ultrasonography following a 16-hour introductory ultrasound course. ⋯ Emergency physicians can be taught focused ultrasonography with a high degree of accuracy, and a 16-hour course serves as a good introductory foundation.

To determine the clinical presentation of emergency department (ED) patients with active pulmonary tuberculosis (TB). ⋯ Patients with active pulmonary TB may have multiple ED visits, and often have nonpulmonary complaints. Tuberculosis risk factors and symptoms are usually present in these patients but often missed at ED triage. The diversity of clinical presentations among ED patients with pulmonary TB will likely make it difficult to develop and implement high-yield triage screening criteria.

To determine whether a hypertonic saline bolus improves cardiac conduction or plasma potassium levels more than normal saline infusion within 15 minutes of treatment for severe hyperkalemia. Previously with this model, 8.4% sodium chloride (NaCl) and 8.4% sodium bicarbonate (NaHCO(3)) lowered plasma potassium equally effectively. ⋯ In this model, 8.4% NaCl bolus reversed cardiac conduction abnormalities within the first 15 minutes after treatment, more rapidly than did the 0.9% NaCl infusion or control. This reversal occurred despite similar reductions in potassium levels.
