trauma guest lecture Flashcards
1st impact in trauma kinetics
car hitting pole
2nd impact in trauma kinetics
chest hitting steering wheel
3rd impact in trauma kinetics
internal organs continuing forward and hitting other structures
snoring in brain injuries
means the brain is swelling causing loss of airway tone
hemorrhagic shock
decreased preload and increased afterload
- hypotensive (MAP less than 65)
- tachycardic
- hypoxic
hypothermic
metabolic acidosis
trauma triad of death
Hypothermia
Coagulation
Acidosis
hemorrhage treatment
crystalloid fluids
blood products
tranexamic acid
fat embolism syndrome
complication of fracture occurring 24-72 hours after injury
Mostly long bone open fractures due to fat entering bloodstream
signs and symptoms of fat embolism syndrome
dyspnea, tachypnea, hypoxemia, confused, petechial rash
treatment of fat embolism syndrome
oxygen, fluids- most resolve on their own
treatment of DVT and PE
D-dimer lab test
heparin/enoxaparin
compression stockings
early ambulation
screening test for DVT
ultrasound
screening test for PE
CT study
compression stockings vs pneumatic compression
both prevent clots but pneumatic mimics muscle contraction
signs of PE
sharp pain with deep breathing
