18
Q

2 most common causes of compartment syndrome?

A
  • Hemorrhage from fracture

* Edema following reperfusion injury

19
Q

What is the capillary pressure that is exceeded in compartment syndrome?

A

30mmHg

20
Q

2 most common signs of compartment syndrome?

A

Pain and paresthesia

21
Q

Types of splints?

A

Rigid
Formable
Improvised
Anatomical

22
Q

Types of rigid splints?

A

(a) Plaster
(b) Fiberglass
(c) Wood
(d) Metal (Scoop Splint)
(e) Inflatable “air splints”

23
Q

What’s significant about rigid splints?

A

CANNOT change in shape

24
Q

Most common diagnosis for use of rigid splint?

A

stable, nondisplaced, closed fracture of a long bone.

25
Q

Contraindications for rigid splint?

A

(a) Early (premature) casting: Casting before maximal swelling has occurred can cause necrosis and compartment syndrome.
(b) Open wound: Never place a cast over an open wound because of the potential for infection. If the wound is not too large, a window may be cut in the cast to monitor it.
(c) Unstable fractures: These fractures need surgical repair; splint only until definitive treatment can be provided.

26
Q

Examples of formable splints?

A

1) Vacuum splints
2) Pillows
3) Blankets
4) Cardboards splints
5) SAM splints
6) Wire ladder splints

27
Q

Examples of anatomical splints?

A

Ankle taping
Ace wrap
Cravats for arm body splints

28
Q

Do you elevate a splinted extremity if spinal injury is not suspected?

A

Yes

29
Q

(c) Injuries below the elbow, ensure the hand is placed in position of function.

A

OK

30
Q

(d) Injuries of the elbow and above, use narrow sling to reduce pressure on elbow.

A

Ok

31
Q

2 types of ankle splints?

A

sugar tong and posterior

32
Q

Splint for ankle sprains to prevent inversion or eversion?

A

Sugar Tong

33
Q

splint may be used with stable tibial or fibular fractures and plantar fasciitis to restrict dorsiflexion or plantar flexion of the foot and ankle complex.

A

Posterior splint

34
Q

What splint does the following?

a) Decrease the pain and damage caused by a femur fracture.
(b) Stabilize the fracture
(c) Align the limb to be placed in splint

A

Hare Traction Splint

35
Q

What splint cannot be used for femur fractures with complete or partial amputation of the lower extremity.

A

Hare Traction Splint

  • because no attachment point to pull traction
36
Q

A

OK

37
Q

Other contraindications of hare traction splint?

A

(b) Hip dislocation
(c) Open femur fracture
(d) Femur fracture close to the knee
(e) Injuries of the upper extremity
(f) Partial amputations or avulsions with bone separation.
(g) Lower leg, foot, or ankle injuries.

38
Q

Complications of hare traction?

A

(a) Compression of nerves, tissues and blood vessels from the splint.
(b) Reduction of distal circulation.
(c) Aggravation of injury to include nerve, vessel, and muscle damage.
(d) Delay in transport.

39
Q

where do you position hare traction splint??
