Fast, accurate, and cost-effective: E-FAST's breakthrough in optimizing thoracic trauma management

Area of Science:

• Emergency Medicine
• Radiology
• Trauma Surgery

Background:

• Thoracic trauma diagnosis often relies on imaging modalities with limitations.
• Extended Focused Assessment with Sonography for Trauma (E-FAST) is a rapid bedside ultrasound technique for evaluating thoracic injuries.

Purpose of the Study:

• To evaluate the diagnostic accuracy of E-FAST for detecting pneumothorax, hemothorax, and pulmonary contusions.
• To compare E-FAST performance against thoracic computed tomography (CT) as the reference standard.

Main Methods:

• Retrospective analysis of 202 adult thoracic trauma patients from 2016-2021.
• E-FAST diagnostic accuracy was calculated using CT as the reference standard.

Main Results:

• E-FAST demonstrated high sensitivity (90% for pneumothorax, 86% for hemothorax) and specificity (95% for both).
• E-FAST was superior to chest radiography in detecting pleural complications and facilitated immediate thoracic drainage in 39.1% of cases.
• A four-fold cost reduction was observed compared to CT.

Conclusions:

• E-FAST exhibits high diagnostic accuracy for pneumothorax and hemothorax in thoracic trauma patients.
• The technique facilitates rapid bedside assessment and influences immediate surgical decision-making.
• Selection bias towards critically injured patients may limit generalizability to clinical outcomes.
