SSM TCAR review
A hemothorax presents a problem where in the cascade? - answers-Ventilation and Hgb availability
CT insertion at 4-5th ICS
Blood loss is commonly the intercostal vessels
A massive PE symptom? - answers-Sudden change in mental status
Neck vein distention
Hemodynamic instability
Low O2 sat
A simple pneumothorax presents a problem where in the cascade? - answers-Ventilation
Deflated section of the lung is not participating in gas exchange
An isolated PTX can be treated with a CT in the 2nd ICS
A tension pneumothorax presents a problem where in the cascade? - answers-Ventilation & CO
Pulsus paradoxus and unilateral breath sounds
Banked blood causes what electrolyte abnormalities? - answers-Elevated K-released from old or
damaged blood cells
Decreased Ca-citrate in blood binds with calcium so the ionized Ca level is low
Blunt trauma Classifications include? - answers-MVA
Auto vs. pedestrian
Falls
Struck by or against an object
,Car vs pedestrian injuries depend on? - answers-Point of contact with the care
Height of hood & bumper
Size & weight of vehicle
Height of patient
Direction patient was facing when struck
Care of an amputated part includes? - answers-Cleaning off any visible debris, sealing amputated part in
a plastic bag, and placing the bag in an ice water solution
Characteristic of wounding agent? - answers-Type of energy and how it was applied
Define Shock? - answers-A state in which cellular oxygen demand exceeds supply
When the cost of tissue oxygen is higher than the body can pay, an oxygen debt develops.
Dose of energy is? - answers-The nature and amount of force
Energy transmission in a rollover depends on? - answers-Deceleration distance
Energy is dissipated over the distance of the roll and whether or not the occupants are restrained
Factors predicting fall injuries are? - answers-Fall height (velocity)
Landing surface (deceleration distance)
Point of impact on the body
Fetal demise in trauma is most likely due to? - answers-Placental abruption
For every second of fall time, speed increases by? - answers-Speed increases by approximately 20 MPH
Force - answers-The dose of energy involved
, H & H is a measure of? - answers-It is a measure of hemodilution rather than blood loss.
How are bowel injuries assessed? - answers-Signs of infection-fever leukocytosis
rebound tenderness
Free air in the belly-Hollow viscous rupture
How are closed mid-shaft femur fractures managed? - answers-Intramedullary nail fixation
How are hepatic lacerations managed? - answers-Need serial abdominal exams, Hgb, liver enzyme levels,
and coagulation studies
How are lateral compression fractures managed? - answers-Usually required ORIF
How are open book pelvic fractures managed? - answers-May be managed with external fixators
How can we keep trauma patients warm? - answers-Forced air warmers, warm IV fluids, keep room very
warm. Acidosis and coagulopathies will not correct unless we reverse hypothermia
How do you calculate expected PaO2? - answers-FIO2 x 5
If it's less than expected for a given FIO2, it is a diffusion problem
How is the bowel injured in blunt abdominal trauma? - answers-Hollow structures pop dues to a direct
blow or hyperflexion over a fixed object causing an increase in intrabdominal pressure
How is the pancreas injured in blunt trauma? - answers-Usually caused by direct compression of the
organ against the rigid spine
How long do spleen injury patients have to avoid contact sports? - answers-For up to 8 weeks
How many ATP molecules are produced with oxygen & glucose? - answers-32 ATP molecules
