Reducing diltiazem-related hypotension in atrial fibrillation: Role of pretreatment intravenous calcium.
This study evaluated the efficacy of intravenous (IV) calcium pretreatment for preventing diltiazem-induced hypotension and assessed its safety in adult patients with atrial fibrillation (AF)/atrial flutter (AFL) with rapid ventricular response (RVR). ⋯ IV calcium pretreatment effectively prevents diltiazem-induced hypotension in patients with AF/AFL with RVR without compromising the efficacy of diltiazem in achieving and maintaining ventricular rate control.

While use of point-of-care ultrasound (POCUS) has become widespread in emergency medicine, its adoption and usage among emergency clinicians is variable. In this study, we explored the barriers and facilitators to POCUS use among emergency medicine clinicians in a tertiary care emergency department in the United States by clinical role and perceived usability of POCUS. ⋯ Participants reported that POCUS facilitates patient disposition and clinical supervision enhances its use. Early POCUS education in professional school and continued POCUS training in clinical practice could facilitate POCUS use clinically. Structured POCUS courses and continued medical education programs may provide protected time to learn and practice POCUS. Moreover, accessible and standardized machines in the clinical environment could improve POCUS usage.
