Peri-intubation cardiac arrest and hypotension in patients with septic shock occur often in the emergency department (ED) and ultimately lead to worse clinical outcomes. In recent years, the use of push-dose, or bolus-dose, vasopressors in the ED have become common practice for transient hypotension and bridging to continuous infusion vasopressors. Push-dose epinephrine and phenylephrine are the agents used most frequently in this scenario. ⋯ A 63-year-old woman who was apneic and pulseless presented to our ED. After 4 min of cardiopulmonary resuscitation, spontaneous circulation was achieved, and the patient was intubated for airway protection. She became hypotensive with a blood pressure of 55/36 mm Hg. After receiving a 1-L bolus of lactated Ringer solution, she remained hypotensive with blood pressure of 80/51 mm Hg and a pulse of 129 beats/min. One unit of intravenous vasopressin push bolus was administered. Within 1 min, her hemodynamics improved to a blood pressure of 141/102 mm Hg and pulse of 120 beats/min. Over the next 2 h, her mean arterial pressure slowly and progressively declined from 120 to 80. No further vasoactive medications were required for approximately 120 min until norepinephrine and vasopressin was initiated for septic shock. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report discusses the use of push-dose vasopressin as an alternate vasoactive medication to improve hemodynamics in a patient with vasodilatory septic shock.

Brain noncontrast computed tomography (CT), CT angiography, and magnetic resonance imaging have been used clinically for decades, and emergency physicians have a good understanding of their indications, the meaning of their results, and some facility with the interpretation of CT. However, brain CT perfusion (CTP) is relatively new and emergency physicians are less familiar with its basic concepts, indications, and role in managing patients with neurological emergencies. ⋯ Taking care of patients with large-vessel occlusions is multidisciplinary, and emergency physicians need to understand CTP imaging and its clinical utility.

The management of life-threatening bleeding in patients who are receiving direct oral anticoagulants (DOACs) is a serious medical concern. ⋯ The current guidelines for management of DOAC-associated bleeding are being updated to reflect that the reversal agent for rivaroxaban and apixaban is now available. For other FXa inhibitors, in the absence of a reversal agent, nonspecific strategies that include PCCs are recommended. The population of patients anticoagulated with DOACs is growing, and we hope that specific reversal agents will improve the approach to management of major bleeding in this population.

Intussusception can lead to significant morbidity in affected children secondary to tissue ischemia and necrosis. When a child outside of the classic age range presents with symptoms other than intermittent abdominal pain, the diagnosis of intussusception can be difficult and is often delayed. ⋯ We present the case of a three-month-old boy who presented to the emergency department with waxing and waning mental status and seizure-like activity who was ultimately diagnosed with intussusception. The effective use of bedside ultrasonography, by the attending pediatric radiologist, enabled an interdisciplinary team to explore abdominal etiologies in parallel with testing for more commonly seen causes of altered mental status. This led to an expedited diagnosis and successful definitive management. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Intussusception is a common pediatric emergency encountered by emergency physicians where a timely diagnosis can have a profound impact on patient outcomes. Previous case reports highlight how easily intussusception can be overlooked with this atypical neurologic presentation. Furthermore, because patients with profound altered mental status are often too ill to leave the emergency department for diagnostic testing, bedside abdominal ultrasonography may be helpful in these patients.

Poor adherence to evidence-based guidelines and overuse of broad-spectrum antibiotics has been noted in the emergency department (ED). There is limited evidence on guideline-congruent empiric therapy for urinary tract infections (UTIs) and uropathogen susceptibilities in the ED observation unit (EDOU). ⋯ The majority of patients in this study were provided guideline-congruent empiric therapy. Nevertheless, there are opportunities to optimize empiric UTI treatment and improve antibiotic stewardship in the EDOU.
