Ultrasound-guided regional anesthesia (UGRA) in the emergency department: a scoping review.

Introduction: While many studies have been published on Ultrasound-guided regional anesthesia in the Emergency Department (ED), there has been no previous study assessing the current state of the literature based in the form of a scoping review.

Objective: The purpose of this study is to evaluate the current state of the literature on UGRA performed in the ED setting.

Methods: EMBASE, MEDLINE, CINAHL, and Cochrane databases were searched for studies.

Optimizing Use of High-Sensitivity Troponin for Risk-Stratification of Acute Pulmonary Embolism.

Background:  High-sensitivity troponin T (HS-TnT) may improve risk-stratification in hemodynamically stable acute pulmonary embolism (PE), but an optimal strategy for combining this biomarker with clinical risk-stratification tools has not been determined.

Study Hypothesis:  We hypothesized that different HS-TnT cutoff values may be optimal for identifying (1) low-risk patients who may be eligible for outpatient management and (2) patients at increased risk of clinical deterioration who might benefit from advanced PE therapies.

Methods:  Retrospective analysis of hemodynamically stable patients in the University of Michigan acute ED-PE registry with available HS-TnT values.

Variability in Interpretation of Echocardiographic Signs of Tamponade: A Survey of Emergency Physician Sonographers.

Background: Cardiac tamponade is associated with high mortality, and making the diagnosis is a core skill of emergency physicians. Proper diagnosis relies on specific clinical and echocardiographic findings. It is not known whether expert sonographers consistently recognize echocardiographic signs of tamponade.

Prediction of in-hospital deterioration in normotensive pulmonary embolism remains elusive: external validation of the calgary acute pulmonary embolism score.

Acute pulmonary embolism (PE) is a frequently diagnosed condition. Prediction of in-hospital deterioration is challenging with current risk models. The Calgary Acute Pulmonary Embolism (CAPE) score was recently derived to predict in-hospital adverse PE outcomes but has not yet been externally validated.

Adverse Clinical Outcomes Among Patients With Acute Low-risk Pulmonary Embolism and Concerning Computed Tomography Imaging Findings.

Importance: Most patients presenting to US emergency departments (EDs) with acute pulmonary embolism (PE) are hospitalized, despite evidence from multiple society-based guidelines recommending consideration of outpatient treatment for those with low risk stratification scores. One barrier to outpatient treatment may be clinician concern regarding findings on PE-protocol computed tomography (CTPE), which are perceived as high risk but not incorporated into commonly used risk stratification tools.

Objective: To evaluate the association of concerning CTPE findings with outcomes and treatment of patients in the ED with acute, low-risk PE.
