How to Determine Fluid Management Goals during Continuous Kidney Replacement Therapy in Patients with AKI: Focus on POCUS.

The utilization of kidney replacement therapies (KRT) for fluid management of patients who are critically ill has significantly increased over the last years. Clinical studies have suggested that both fluid accumulation and high fluid removal rates are associated with adverse outcomes in the critically ill population receiving KRT. Importantly, the ideal indications and/or fluid management strategies that could favorably affect these patients are unknown; however, differentiating clinical scenarios in which effective fluid removal may provide benefit to the patient by avoiding congestive organ injury, compared with other settings in which this intervention may result in harm, is direly needed in the critical care nephrology field. In this review, we describe observational data related to fluid management with KRT, and examine the role of point-of-care ultrasonography as a potential tool that could provide physiologic insights to better individualize decisions related to fluid management through KRT.

Diagnosis and Management of Pulmonary Embolism.

Pulmonary embolism is a challenging pathology commonly faced by emergency physicians, and diagnosis and management remain a crucial skill set. Inherent to the challenge is the breadth of presentation, ranging from asymptomatic pulmonary emboli to sudden cardiac death. Diagnosis and exclusion have evolved over time and now use a combination of clinical decision calculators and updates to the classic d-dimer cutoffs. Management of pulmonary emboli revolves around appropriate anticoagulation, which for most of the patients will comprise newer oral agents. However, there remains a substantial degree of practice variation and ambiguity when it comes to higher risk patients with submassive or massive pulmonary emboli.

Randomized Evaluation of Videoconference Meetings for Medical Students' Mid-clerkship Feedback Sessions.

INTRODUCTION: Videoconferencing has been employed in numerous medical education settings ranging from remote supervision of medical trainees to conducting residency interviews. However, no studies have yet documented the utility of and student response to videoconference meetings for mid-clerkship feedback (MCF) sessions required by the Liaison Committee on Medical Education (LCME). METHODS: From March 2017 to June 2018, third-year medical students rotating through the mandatory, four-week emergency medicine (EM) clerkship at a single medical school were randomly assigned either to a web-based videoconference meeting via Google Hangouts, or to a traditional in-person meeting for their MCF session. To compare students' MCF experiences we sent out an electronic survey afterward to assess the following using a 0-100 sliding scale: overall satisfaction with the meeting; the effectiveness of communication; the helpfulness of the meeting; their stress levels, and the convenience of their meeting location. The survey also collected data on these demographic variables: the name of the faculty member with whom the student met; student gender, age, and interest in EM; location prior to meeting; meeting-method preference; and number of EM shifts completed. RESULTS: During the study period, 133 third-year medical students responded to the survey. When comparing survey responses between individuals who met online and in person, we did not detect a difference in demographics with the exception of preferred meeting method (p=0.0225). We found no significant differences in the overall experience, helpfulness of the meeting, or stress levels of the meeting between those who met via videoconference vs. in-person (p=0.9909; p=0.8420; p=0.2352, respectively). However, individuals who met in-person with a faculty member rated effectiveness of communication higher than those who met via videoconference (p=0.0002), while those who met online rated convenience higher than those who met in-person (p<0.0001). Both effects remained significant after controlling for preferred meeting method (p<0.0001 and p=0.0003, respectively) and among EM-bound students (p=.0423 and p<0.0110, respectively). CONCLUSION: Our results suggest that LCME-required MCF sessions can be successfully conducted via web-based programs such as Google Hangouts without jeopardizing overall meeting experience. While the convenience of the meetings was improved, it is also important for clerkship directors to note the perceived deficit in the effectiveness of communication with videoconferencing.

Takutsubo cardiomyopathy and flash pulmonary edema in a trauma patient.

BACKGROUND: First described in Japanese literature in 1991, Takotsubo cardiomyopathy (TCM), or "broken heart" syndrome, continues to be described in novel circumstances. Commonly mistaken for acute coronary syndrome (ACS) due to similar clinical symptoms and electrocardiogram changes, it usually affects postmenopausal women and those in acute emotional or physical stress. Named for the resemblance of apical ballooning and dyskinesis to the Japanese octopus trap, the pathogenesis is poorly understood. Believed to be associated with catecholamine surges during extreme stress, TCM has been reported with grieving, lightning strikes, burns, injuries, and anesthesia. We describe a unique case occurring after a significant motor-vehicle collision (MVC) without apparent injury. OBJECTIVE: Our aim was to discuss the presentation and management of a cardiac syndrome that can complicate the care of trauma patients by mimicking other life-threatening pathologies. CASE REPORT: A 59-year-old healthy female in a rollover MVC was found suspended upside down with her seatbelt across her neck. She was hypoxic, in respiratory distress, and had nonsustained ventricular tachycardia en route. She was dyspneic without pain and had no signs of external trauma. She was assessed with chest x-ray study, focused assessment with sonography in trauma, and electrocardiogram, which demonstrated inferior ST elevation. After negative trauma computed tomography scans, she underwent coronary angiography. Ventriculography revealed apical inferior and anterior ballooning without coronary artery occlusion. She rapidly improved and was discharged in stable condition 2 days later. CONCLUSIONS: TCM presents a diagnostic challenge to the emergency physician. In a patient of this age and mechanism, alternate intrathoracic pathologies, such as ACS, aortic injury, pulmonary contusion, and pneumothorax must be considered.
