Q

hemorrhagic shock

A

decreased preload and increased afterload
- hypotensive (MAP less than 65)
- tachycardic
- hypoxic
hypothermic
metabolic acidosis

A

complication of fracture occurring 24-72 hours after injury
Mostly long bone open fractures due to fat entering bloodstream

16
Q

parietal pleura

A

outer lining attached to chest wall

17
Q

visceral pleura

A

inner lining covering lungs

18
Q

lungs

A

are always inflated due to more negative pressure inside than outside which creates a vacuum

19
Q

lung collapse

A

occurs when inside pressure = outside pressure

20
Q

pneumothorax

A

presence of air in the pleura
- can be open or closed/spontaneous

21
Q

closed/spontaneous pneumothorax

A

most commonly seen in young, tall and thin males
- air bleb ruptures at top of long apex and moves from high pressure in alveoli to low pressure in pleural space

22
Q

open pneumothorax

A

chest wall is damaged leading to air entering pleural space
- air enters pleural space with inspiration and exits during expiration

23
Q

tension pneumothorax

A

occurs in penetrating or blunt trauma where intrapleural pressure is greater than atmospheric pressure and air can enter but cannot exit

24
Q

signs and symptoms of tension pneumothorax

A

mediastinal shift, tracheal deviation, no preload, high afterload

25
Q

closed pneumothorax treatment

A

chest tube

26
Q

tension pneumothorax treatment

A

needle decompression followed by chest tube insertion

27
Q

compartment syndrome

A

increased pressure which compromises circulation due to muscle not being able to stretch and occurs most often in soft tissue injuries and fractures
- necrosis can occur within 4 hours

28
Q

6 P’s of compartment syndrome

A
  1. PAIN OUT OF PROPORTION
  2. paresthesia
  3. poikilothermia
  4. pallor
  5. pulselessness
  6. paralysis
29
Q

treatment of compartment syndrome

A

remove restrictive devices, elevate limb to heart level (not higher), fasciotomy

30
Q

complex regional pain syndrome

A

pain more severe than the injury warrants

31
Q

signs and symptoms of complex regional pain syndrome

A

skin color changes, increased sweating, loss of bone density

32
Q

treatment of complex regional pain syndrome

A

prevent through early mobilization, antidepressants, Gabapentin

33
Q

laceration

A

disruption in skin continuity and often occurs secondary to trauma

34
Q

laceration treatment

A

check tetanus, suture

35
Q

localized hemorrhage

A

ecchymosis will form

36
Q

contusion treatment

A

cool compress to vasoconstrict
