The tricuspid regurgitation pressure gradient (TRPG) reflects the difference in pressure between the right ventricle and right atrium (ΔPRV-RA). Its estimation by echocardiography correlates well with that obtained using right-heart catheterization. An elevated TRPG is an important marker for identifying right ventricular dysfunction in both the acute and chronic settings. ⋯ This could lead to erroneous fluid tolerance assessments, and potentially harmful resuscitative and airway management strategies. In this manuscript, we illustrate the pathophysiology and potential pitfall of wide-open TR through a series of cases in which emergency physicians made the diagnosis using cardiac point-of-care ultrasound. To our knowledge, this clinical series is the first to demonstrate recognition of the paradoxically-low TRPG of wide-open TR, which guided appropriate management of critically ill patients in the emergency department.

Case Reports
Atraumatic splenic rupture secondary to granulocyte-colony stimulating factor medication exposure.
Hematopoietic hormones such as granulocyte-colony stimulating factors are commonly used prevent neutropenia in patients undergoing chemotherapy and to prepare patients for bone marrow donations. In rare cases, splenic injury can result from exposure to this medication. We present the case of a 30-year-old man who presented to the emergency department the day after a bone marrow donation procedure complaining of severe, acute onset left upper quadrant abdominal pain, radiating to the shoulder. ⋯ An emergent confirmatory CT with contrast of the abdomen confirmed the initial ultrasound examination suspicion of an atraumatic splenic rupture and with evidence of venous bleeding but without active arterial extravasation. An emergent trauma surgery consultation was placed, and he underwent embolization with an uneventful recovery. This case report highlights the need for a high index of suspicion for atraumatic splenic rupture in patients exposed to these types of granulocyte-colony stimulating factors.

We assessed whether initiation of oral enteral nutrition in the emergency department (ED) for patients with bronchiolitis hospitalized on humidified high flow nasal cannula (HHFNC) was associated with a shorter hospital length of stay (LOS) without an increase in return ED visits or hospital readmissions. ⋯ Initiation of oral enteral nutrition in the ED for patients with bronchiolitis on HHFNC is associated with a shorter hospital LOS without an increase in return ED visits or hospital readmissions. Future prospective studies are needed to develop feeding recommendations for children with bronchiolitis receiving HHFNC support.

Acute abdominal pain is a very common chief complaint in the pediatric population, accounting for 5-10% of emergency department (ED) visits. Etiology differentiation is determined by complete history and physical examination, basic laboratory studies, and a variety of imaging study options. In this case report, we present an 8-year-old female with an unusual etiology of acute lower abdominal pain. ⋯ This case report demonstrates the youngest documented case of OVT. This patient was not in the peripartum period and did not have any identifiable risk factors. Given this unprovoked OVT in a pediatric patient, in patients presenting with abdominal pain with unspecified etiology, advanced imaging studies may be helpful in establishing a diagnosis.
