14 Introduction to Focused Assessment of Sonography in Trauma (FAST) Scan
Lo Zhen Zhen
The introduction of ultrasound technology has transformed the approach to trauma care in emergency medicine. FAST and eFAST scans are non-invasive, bedside procedures that have become crucial in the rapid assessment of trauma patients. This chapter aims to provide medical students with the knowledge and practical skills needed to perform these ultrasonography methods efficiently. Students will learn to integrate FAST and eFAST scans into their clinical practice by learning the principles, methodologies, and clinical applications.
Learning Objectives
- Comprehend the underlying principles of ultrasound technology as applied in FAST and eFAST.
- Perform FAST scans confidently, including appropriate probe placement and orientation.
- Extend the FAST protocol to include thoracic assessment, mastering the eFAST technique.
- Interpret ultrasound findings accurately to identify pathologies in trauma patients.
- Recognize the limitations and clinical implications of FAST and eFAST in clinical practice.
Chapter Key Terms
- Focused Assessment with Sonography in Trauma (FAST) scan: A focused assessment with sonography in trauma, identifying free fluid in the abdomen, pelvis or pericardium.
- Extended FAST (eFAST) Scans: Extended FAST, incorporating thoracic assessment to detect pneumothorax and hemothorax.
