Chapter 19 Emergent Ultrasound Procedures Flashcards
Used to sample intraperitoneal space for evidence of damage to viscera and blood vessels
Peritoneal lavage
Limited examination of abdomen/pelvis to evaluate free fluid/pericardial fluid
FAST scan
Focus
Assessment with
Sonography for
Trauma
FAST scan, where do they look?
- perihepatic(Morrison’s pouch)
- perisplenic(splenorenal recess)
- parabolic gutters
- cul de sac
- pericardium
FAST exam takes ____ minutes
4 minutes
Bloody fluid In abdomen
Hemoperitoneum
Most common areas for fluid/blood to collect:
Subhepatic space and pelvis
Hematomas and localized lacerations initially appear:
Hypoechoic, low-level echoes
Hematomas and localized lacerations appear _____ as blood begins to coagulate
Echogenic
Hematomas and localized lacerations over time appear:
Anechoic due to hemolysis(destruction of RBC)
Epigastric pain radiating to the back is consistent with:
Pancreatitis
Pancreatitis will initially have elevated _____
Amylase
Pancreatitis will later have elevated ___
Lipase
Pancreatitis sonographically:
Irregular borders, increased vascularity, Normal to edematous hypoechoic texture
Abdominal/chest pain radiating to the back is consistent with:
Aortic aneurysm/dissection
Sonographic findings for aortic aneurysms/dissection:
- false lumen
- intimal flap
- most are ascending
With aortic aneurysms/dissection, you must document the location of aneurysm to renal veins/arteries because:
This determines treatment
aortic aneurysms/dissection clinical signs:
Syncope
Hypotension
Abdominal/chest pain radiating to back
Most common cause of abdominal aortic dissection:
Hypertension(70-90%)
cause of abdominal aortic dissection: 16% of the time
Marfan syndrome
Urolithiasis: hematuria presents in ____% of cases
85%
Scrotal rupture sonographic findings:
- scrotal wall thickening
- interruption of outer layer(tunica albuginea
- irregular contour
4-6 hours after testicular torsion, testis appear:
Swollen and hypoechoic
24 hours after testicular torsion, testis appear:
Heterogeneous due to hemorrhage
