Rapid Ultrasound for Shock and Hypotension: A Clinical Update for the Advanced Practice Provider: Part 2

Area of Science:

• Emergency Medicine
• Point-of-Care Ultrasound

Background:

• Undifferentiated hypotension presents a diagnostic challenge in emergency settings.
• The Rapid Ultrasound for Shock and Hypotension (RUSH) examination is a valuable bedside tool.
• Clinical assessment alone may be insufficient for rapid diagnosis of shock etiologies.

Purpose of the Study:

• To describe the RUSH examination protocol for diagnosing undifferentiated hypotension.
• To highlight the utility of RUSH in differentiating shock types (hypovolemic, obstructive, cardiogenic, distributive).
• To emphasize the importance of training advanced practice nurses in the RUSH examination.

Main Methods:

• The RUSH examination systematically assesses cardiac function ('pump'), intravascular volume ('tank'), and vascular integrity ('pipes').
• Clinicians utilize ultrasound to identify specific conditions like cardiac tamponade, pneumothorax, or deep vein thrombosis.
• A structured protocol guides the examination for efficient diagnosis.

Main Results:

• The RUSH examination provides rapid, targeted information to supplement physical assessment.
• It aids in differentiating between various causes of shock.
• Successful implementation relies on clinician proficiency in ultrasonography.

Conclusions:

• The RUSH examination is an effective ultrasound protocol for evaluating patients with undifferentiated hypotension.
• Training emergency department clinicians, particularly advanced practice nurses, in the RUSH protocol is crucial.
• This diagnostic approach enhances the ability to quickly identify and manage shock.
