Bedside echocardiography rapidly and reliably diagnoses pericardial effusion and differentiates between simple effusions and those causing cardiac tamponade.
Bedside ultrasound is a crucial tool for rapidly diagnosing pericardial effusions and identifying cardiac tamponade to guide emergency pericardiocentesis.

May support emergency bedside use for tamponade assessment; leaves open prospective validation across settings.
This review article discusses two clinical cases of patients presenting to the emergency department with pericardial effusions. The role of bedside ultrasound in the detection of pericardial effusions is investigated, with special attention to the specific ultrasound features of cardiac tamponade. Through this review, clinicians caring for patients with pericardial effusions will learn to rapidly diagnose this condition directly at the bedside. Clinicians will also learn to differentiate between simple pericardial effusions in contrast to more complicated effusions causing cardiac tamponade. Indications for emergency pericardiocentesis are covered, so that clinicians can rapidly determine which group of patients will benefit from an emergency procedure to drain the effusion.

Perera et al. (2012) conducted a review in Pericardial effusion and cardiac tamponade (n=2). Bedside ultrasound was evaluated. Bedside echocardiography rapidly and reliably diagnoses pericardial effusion and differentiates between simple effusions and those causing cardiac tamponade.
