This document provides information about FAST (Focused Assessment with Sonography for Trauma) exam. It discusses the goal of FAST which is to identify fluid in locations where it does not normally belong and detect visceral injury. It describes how free fluid appears anechoic and will accumulate in areas of injury or overflow to dependent areas. The procedure involves using a 3.5-5MHz convex transducer to view specific regions for any fluid collections, including the pericardial sac, perihepatic region, pelvis, and thoracic views. Causes of false negatives and positives are discussed.

4. • Acute blunt or penetrating torso trauma ( stable or unstable patients )
• Trauma in pregnancy
• Paediatric trauma
• Subacute torso trauma ( unexplained hypotension )

5. • To identify fluid in a location where it does not normally belong and
detect visceral injury.
• Free fluid usually appears anechoic
• Accumulation in area of injury
• Overflow into dependent areas ( pouch y Douglas, Morrisons pouch ) and into
thoracic cavity

6. • Pericardial Sac / Xiphoid Process
• Peri hepatic Region
• Peri splenic Region
• Pelvis
• Right Thoracic View
• Left Thoracic View

7. • Patient in supine position
• 3.5-5.0 MHz Convex transducer
• put the probe in following sequence and try to find any fluid or blood
collection in following regions -
1. Xiphoid transverse view - Pericardial view look for fluids around the heart
2. Right upper quadrant longitudinal view - Perihepatic view , Morison pouch
view
3. Left upper quadrant longitudinal view - In Perisplenic region
4. Supra pubic longitudinal & transverse view - In Suprapubic regions , Pouch of
Douglas
• Right & Left thoracic view
• Put the probe one by one both side of intercostal space in mid clavicular line,
look for pneumothorax
• Costophrenic angle for Hemothorax

10. • Free fluids appears as anechoic fluids
• The FAST evaluate both pericardial collections as well as
hemoperitoneum and pelvic hematoma
• Pneumothorax - BARCODE / STRATOSPHERE Sign

13. • Mesentric injury
• Bowel injury
• Retro peritoneal Injury
• Diaphragm injury
• Obesity
• Subcutaneous emphysema

14. • Epicaridal Fat Pads, Pericarial cyst
• Pre exiting ascites, pleural and pericardial effusions due to medical
conditions
• Seminal vesicles mistaken for pelvic free fluid in the young male patient
