Ultrasound Measurement of the Intervertebral Space in the Lateral Recumbent Versus Sitting Positions.

Background: Diagnostic lumbar puncture (LP) is an invasive procedure routinely performed within the emergency department (ED). LP is traditionally performed with the patient in either the lateral recumbent or sitting position. We investigated if the intervertebral space is larger in one of these positions.

Where There's Smoke, There's Fire: A Case Report of Turbulent Blood Flow in Lower Extremity Point-of-care Ultrasound in COVID-19.

Introduction: Coronavirus disease 2019 (COVID-19) may predispose patients to increased risk of venous thromboembolism (VTE) due to various pathophysiological mechanisms, including but not limited to endothelial injury, inflammation, cytokine-mediated microvascular damage, and reactive thrombocytosis. A high risk of vessel thrombosis correlates with disease severity, making early identification and treatment of prime consideration.Although identification of a deep venous thrombosis (DVT) or pulmonary embolism warrants immediate treatment with anticoagulation, trying to predict which COVID-19 patients may be at increased risk for developing these pathologies is challenging.
