What are the indications for performing an eFAST examination?

Blunt trauma

Penetrating trauma

Unexplained shock/Hypotension

None of the above

Which are true regarding advantages of performing an EFAST examination?:

Negates the need for a CT in all positive scans

Can help determine whether an emergent intervention such as chest tube thoracostomy is required

Expedites time to surgery in an unstable patient

What is a cause of substandard images whilst performing an eFAST scan?:

Significant subcutaneous emphysema

Obesity

Bowel gas which may obscure images

All of the above

Disadvantages of performing an eFAST examination include

Inability to identify retroperitoneal haemorrhage

The examination is not repeatable

The location of fluid does not diagnose the injured organ

Low overall sensitivity (~90%), but a higherspecificity (~95%) for detection of intraperitoneal free fluid

In the supine patient, fluid first collects in the right paracolic gutter:

True

False

Tick all transducers that may be used to get adequate RUQ views:

Curvilinear

Linear

Phased array

In the absence of thoracic pathology, the thoracic spine is unable to be imaged above the diaphragm:

True

False

When scanning the LUQ, fluid accumulates:

In the Splenorenal recess initially

All around the Spleen

eFAST is the investigation of choice in the identification of a hollow viscus injury:

True

False

To reduce the posterior acoustic enhancement caused by the fluid-filled bladder (and therefore free fluid being missed in the pelvic view) you should:

Decrease the depth

Increase the depth

Decrease the far gain

Increase the far gain
