eFAST Post-Test

Email

There are similar levels of accuracy in performing an eFAST in the adult and paediatric populations:

True

False

Any fluid visualised in the Pouch of Douglas in a female is pathological:

True

False

Clotted blood on eFAST may appear as:

Hyperechoic

Hypoechoic

Anechoic

What pathological process can cause anechoic free fluid in the peritoneum?:

Ascites

Intraperitoneal haemorrhage

Urine (e.g. ruptured bladder)

All of the above

The most dependent area and therefore the first place to find free intraperitoneal fluid in a supine trauma patient is Morrison’s pouch, despite the spleen being the most commonly injured organ:

True

False

The splenorenal angle lies slightly more inferior than Morrisons Pouch:

True

False

In the LUQ, the ultrasound beam should be directed posterior (towards the bed):

True

False

Tick all potential intraperitoneal free fluid mimics:

Gallbladder

Perinephric fat

Stomach or duodenum

Inferior Vena cava

To determine whether perinephric fat vs clot is present, the opposite side should be imaged as they are usually symmetrical:

True

False

Challenges in performing eFAST examinations on pregnant patients include:

Patient may need to be placed in left lateral position

The gravid uterus can limit the view of the bladder making pelvic views variable

Diaphragmatic elevation which may require repositioning of the probe

Ultrasound cannot exclude placental abruption
