Magnesium supplementation is frequently recommended despite limited evidence to support its use. ⋯ Magnesium coadministration during hypokalemia treatment did not affect time to serum potassium normalization but was associated with more hypermagnesemia.

Distribution of Lower Extremity Deep Vein Thrombosis and Implications for Limited Compression Ultrasound Examinations.
Limited compression bedside ultrasonography (LCUS) including two-point, three-point, and extended compression examinations have become increasingly popular among emergency physicians to assess for lower extremity deep venous thrombosis (DVT). ⋯ In our study, a significant number of DVTs were identified in sites that may have been potentially missed on LCUS examinations, thereby supporting the use of complete duplex ultrasonography when available.

Much controversy surrounds the use of orthostatic vital signs (OVS), including their indications, performance, and interpretation. This can lead to conflict between nurses, physicians, and consultants. This article summarizes the evidence for OVS in selected emergency department (ED) indications and the basis for a rapid measurement protocol. ⋯ OVS are useful in selected patients, in a variety of frequent presentations, but their indications and implications for a patient's care are subject to physician interpretation. Given their ease of measurement and effect on decision-making, physicians may consider measuring them early in the evaluation of selected patients.
