Intravenous (IV) vancomycin is commonly used to treat a variety of infections caused by methicillin-resistant Staphylococcus aureus (MRSA). The practice of administering a single dose of IV vancomycin prior to emergency department (ED) discharge may be clinically ineffective and foster antimicrobial resistance. Furthermore, this practice introduces an unnecessary infection risk along with preventable adverse effects while potentially increasing ED length of stay (LOS). There is a paucity of literature identifying patient characteristics and objective findings in this patient population, which may foster future antimicrobial stewardship initiatives in the ED. ⋯ Despite a lack of clinical efficacy reported in prior literature and the potential risks, administration of a one-time dose of IV vancomycin prior to ED discharge is commonly encountered in clinical practice. There are opportunities for enhanced antimicrobial stewardship related to IV vancomycin use in the ED. Areas of future focus include the utilization of oral antimicrobials when clinically appropriate, particularly for skin and soft tissue infections, and clarification of antibiotic allergies.

To determine the rates of clinically significant tachyarrhythmias and mortality in the management of post-resuscitative shock after return of spontaneous circulation (ROSC) in patients with out-of-hospital cardiac arrest (OHCA) who receive a continuous epinephrine versus norepinephrine infusion. ⋯ There was no statistically significant difference in clinically significant cardiac tachyarrhythmias in post-OHCA patients treated with epinephrine versus norepinephrine infusions after ROSC. Re-arrest rates and in-hospital mortality were higher in patients who received epinephrine infusions in the first 6 h post-ROSC. Results of this study add to the literature suggesting norepinephrine may be the vasopressor of choice in post-OHCA patients with post-resuscitative shock after ROSC.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors lower glucose levels by reducing glucose reabsorption in the kidneys, which can lead to ketogenesis. Euglycemic diabetic ketoacidosis (DKA) is a rare but potentially life-threatening complication of SGLT2 inhibitors that can be triggered by trauma. ⋯ Delayed recognition of euglycemic DKA in this case led to progressive metabolic deterioration. This report emphasizes the importance of promptly suspecting, diagnosing, and treating euglycemic DKA in patients with traumatic injuries who exhibit high anion-gap metabolic acidosis, ketonuria, and glucosuria-even if they do not have significant hyperglycemia.
