Syncope | Point-of-Care Ultrasound in the Emergency Department Evaluation of Syncope

Syncope research study

What is the primary objective of this study?

The purpose of this study is to determine whether point-of-care (bedside) ultrasound assists physicians in the evaluation and management of patients with syncope.

Who is eligible to participate?

Inclusion Criteria: - 18 years and older presenting to the ED with acute syncope (defined as transient loss of consciousness) or near syncope (sensation of impending but not actual loss of consciousness) as a reason for ED visit. Exclusion Criteria: - persistent altered mental status - alcohol or illicit drug-related loss of consciousness - definite seizure, and transient loss of consciousness caused by head trauma.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?


Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Other:Point-of-Care UltrasoundPerformance of a focused cardiac ultrasound including a qualitative assessment of left ventricular function, pericardial effusion, right ventricular strain, proximal ascending aortic diameter, and inferior vena cava size and collapsibility

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Immediate UltrasoundA point-of-care ultrasound will be performed during the initial evaluation of the patient after randomization (Defined as Time 0)

Delayed UltrasoundA point-of-care ultrasound will be performed by the provider at 60 min after initial randomization
