Abdo Flashcards
% of abdo injuries associated with head and or chest
75%
Why do abdo injuries typically have a high morbidity or mortality?
severity of associated injuries
– severe haemorrhage
– difficulty in localising injury
– severity may initially be underestimated
– increase risk of sepsis & multi-organ failure
most common typye of abdo trauma and MOI
blunt and MVA
when are hollow organ injuries more common?
with severe solid organ inury
what is eFAST
extended Focused Assessment with Sonography in Trauma
eFAST sequence
- RUQ
- Right chest- lower
- Right chest- upper
- Left chest- upper
- Left chest- lower
- Left upper quadrant
- Pericardium
- Pelvis
but depends on context of injury
FAST 4 P’s and other regions
Pericardium
– Perihepatic region
– Hepato-renal space (Morrison’s pouch)
– Perisplenic region
– Splenorenal recess
– Pericolic gutters
– Pelvis (Pouch of Douglas) +/- uterus (? foetus)
which area is Morrisons pouch located in during FAST scan?
RUQ
Where is pouch of Douglas visualised in FAST scan
Pelvis
Standard PAN scan
- Non-contrasthead
*Non contrast cervical spine - Contrast-enhanced chest(arterial phase)
- Contrast enhanced abdomen(portal venous)
Delayed phase of abdo/pelvis can show
Useful to assess contrast pooling/contrast extravasation in peritoneum
indicative of active bleeding
Angiogram from aortic arch to vertex can be added to pan scan for
Assess penetrating neck injuries or blunt cerebrovascular injuries
What is a non-con abdo useful for?
suspected abdo bleeds
the 3 lines on a hip and the 3 acetabular sections
Lines: iliopectineal
ilioischial
shentons
Acetabulum: Anterior and posterior edge
Roof.
What do lateral compression injuries to pelvis typically cause?
Fractures of the pubic rami, sacral and iliac wing fractures and sometimes ligamentous.
