Hemophilia and von Willebrand disease (VWD) are the most common congenital coagulation factor deficiencies. Patients with these disorders who experience bleeding complications are often initially managed in the emergency department (ED). ⋯ Emergency medicine providers must have an understanding of the pathophysiology, clinical presentation, and management strategies in order to optimally care for these complex patients.

Shotguns represent a distinct form of ballistic injury because of projectile scatter and variable penetration. Due in part to their rarity, existing literature on shotgun injuries is scarce. ⋯ In the United States, shotgun wounds are an infrequent mechanism of injury. Shotgun wounds as a result of interpersonal violence far outweigh self-inflicted and accidental injuries. White men in their 20s in the southern parts of the country are most commonly affected and thereby delineate the high-risk patient population for injury by this mechanism at a national level.

Bacteremia causes a major worldwide burden, in terms of financial and productivity costs, as well the morbidity and mortality it can ultimately cause. Proper treatment of bacteremia is a challenge because of the species-dependent response to antibiotics. The T2Bacteria Panel is a U.S. Food and Drug Administration-cleared and culture-independent assay for detection of bacteremia, including common ESKAPE pathogens-Escherichia coli, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa-and provides species identification in as little as 3.6 h directly from blood. ⋯ In this ED population, the T2Bacteria assay was a rapid and sensitive detector of bacteremia from common ESKAPE pathogens and showed the theoretical potential to influence subsequent patient therapy, ranging from antibiotic de-escalation to faster time to effective therapy.

Metformin toxicity can lead to profound shock and has a high mortality rate. Supportive care and enhanced elimination are the mainstays of therapy. Intermittent hemodialysis (HD) produces a higher clearance of metformin than continuous veno-venous hemofiltration or hemodiafiltration (CVVH/HDF). Nevertheless, CVVH/HDF has been proposed as an alternative in critically ill patients with the suggestion that hypotension may limit the use of HD. ⋯ Intermittent HD is feasible in metformin toxicity despite persistent shock and high-dose vasopressor support. Mean arterial pressures improved during the course of HD and high blood flow rates were tolerated.
