What type of shock?
marked tachypnea
Severe hemorrhagic shock
What type of shock?
Mild compensated shock
mild increase in ventilatory rate
the most reliable indicator of intra-abdominal bleeding is the presence of what?
hypovolemic shock from an unexplained source
Secondary assessment:
(a) Examine abdomen, flank and back
(b) Palpate for tenderness
(c) Auscultation
(d) Percussion
Palpation
_______ historically thought to be a strong indicator of peritonitis.
Rebound tenderness
Deep or aggressive palpation should be avoided if an obviously injured abdomen why?
in order to avoid dislodging clots or restarting hemorrhage, may also spill intra-abdominal contents.
Significant tenderness to percussion or pain with coughing is a strong indicator for _____
Peritonitis
What is the definitive treatment for patients that have sustained abdominal injuries?
Surgical intervention
In Emergency Departments, STP’s, FRSS’s and many operation platforms _______ exams have become primary bedside modality to assess for intra-abdominal injury
FAST
Details of FAST
What are the image acquisition sites?
RUQ, LUQ, pelvic, pericardial
FAST:
Rotate the probe slightly counterclockwise in the RUQ or clockwise in the LUQ to align with the ribs and eliminate _____
rib shadow
________ can help with the subxiphoid view
Bending the knees
The ____ cardiac view is a secondary cardiac option if unable to get the subxiphoid view
PSLA
What type of probe is used for FAST
curvilinear or phased-array
Scan Planes:
1)RUQ and LUQ – ______
2)Pelvic – ________
3)Cardiac – _________
1) RUQ and LUQ – sagittal
2) Pelvic – transverse and sagittal
3) Cardiac – subxiphoid or PSLA
FAST:
In the RUQ, visualize what 4 areas
Morison’s Pouch,
inferior tip of the liver,
R hemithorax,
sub diaphragmatic space
FAST:
the LUQ, visualize what 4 areas
Splenorenal recess,
inferior tip of the spleen,
L hemithorax,
sub diaphragmatic space
Target goal in the absence of TBI is systolic of ______mmHg. In TBI systolic minimum is ___mmHg
w/o TBI: 80-90
W/ TBI: 90
Treatment for Eviscerated bowel
1) Do not attempt to replace the protruding contents
2) Viscera should be left in place
3) Clean or sterile dressing moistened with saline
4) Initial dressing may be covered with large, dry dressing to keep warm
5) Psychological support, keep patient calm. Any action that increases intra- abdominal pressure can cause more contents to protrude.
