Previous studies have shown an association between hyperoxemia and mortality in patients with out-of-hospital cardiac arrest (OHCA) after cardiopulmonary resuscitation (CPR); however, evidence is lacking in the extracorporeal CPR (ECPR) setting. ⋯ Hyperoxemia was associated with worse neurological outcomes in OHCA patients with ECPR.

Review Case Reports
Diagnosis of Renal Artery Aneurysm by Point-of-Care Ultrasound in the Emergency Department: A Case Report and Brief Review of the Literature.
Renal artery aneurysm (RAA) is defined as a focal dilatation of ≥50% of the adjacent, disease-free artery. Although typically asymptomatic, RAA can lead to hypertension, hematuria, and rupture. The risk of rupture is higher in pregnant patients and may result in the death of the mother and the fetus. We describe a case of RAA discovered on point-of-care ultrasound (POCUS) in the emergency department. ⋯ A 46-year-old woman with no medical history presented to the emergency department with lower abdominal pain, vomiting, diarrhea, and increased urination. POCUS was performed to evaluate the cause of the patient's symptoms. This study revealed a 2.40 cm × 3.65 cm aneurysm in the right kidney. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Rupture of RAA occurs in 3% to 5% of cases. Mortality to both the mother and the fetus is particularly high in gravid patients. RAA may be mistaken for other renal entities such as prominent renal veins or hydronephrosis. Properly identifying this pathology via POCUS can lead to early intervention. © 2022 Elsevier Inc.

Burn injuries in geriatric patients are common and may have significant associated morbidity and mortality. Most research has focused on the care of hospitalized patients after admission to burn units. Little is known about the clinical characteristics of geriatric burn victims who present to the emergency department (ED) and their ED assessment and management. ⋯ Better understanding of ED care for geriatric burn injuries may identify areas in which to improve emergency care for these vulnerable patients.

Febrile neonates undergo lumbar puncture (LP), empiric antibiotic administration, and admission for increased risk of invasive bacterial infection (IBI), defined as bacteremia and meningitis. ⋯ Thirty percent of febrile neonates met low-risk criteria, age > 18 days, reassuring RC and YOS, and could avoid LP and empiric antibiotics. Our low-risk guidelines may improve patient safety and reduce health care costs by decreasing lab testing for cerebrospinal fluid, empiric antibiotic administration, and prolonged hospitalization. These results are hypothesis-generating and should be verified with a randomized prospective study.

Dexmedetomidine is an alternative agent for procedural sedation in the emergency department thanks to its ability to maintain hemodynamic and respiratory stability. Dexmedetomidine must, however, be combined with a powerful analgesic. ⋯ The combination of dexmedetomidine and ketamine provides conscious sedation, bringing comfort and pain relief to patients in optimal conditions for respiratory and hemodynamic safety. However, sedation and recovery times are longer than with conventional drug combinations. The dexmedetomidine-ketamine combination should therefore be recommended for nonurgent procedures and fragile patients.
