bandages

Question 1

first aid of bandages

Answer 1

Reduce further trauma
- Prevent contamination
- Hemostasis
- TEMPORARY fracture stabilization

Question 2

why leave toes out

Answer 2

cool
swollen
painful

Question 3

what causes pressure points

Answer 3

bunching
not uniform pressure

Question 4

3 types of fracture stabilization

Answer 4

heavy
splinted
multi layer- robert jones bandage

Question 5

the primary layer of a bandage is for

Answer 5

Determined immediate wound environment

Most direct effect on healing

Question 6

secondary layer does

Answer 6

early - absorption
later- support

Sequential layers of padding & conforming materials
- Provides absorption (blood, wound exudate)
- Secures 1° layer
- Provides support & pressure

Question 7

3rd layer does

Answer 7

tune the stiffness
Outer layer = physical barrier
- Holds inner layers together

Question 8

advantages of adherent dressing

Answer 8

Facilitate mechanical debridement
- Necrotic tissue, exudate, & debris adhere to dressings

Good in early stages or grossly contaminated
wounds

Question 9

disadvantages of adherent dressing

Answer 9

Delay fibroplasia & epithelialization
▪ Painful to remove
▪ Strike through
- Bacterial translocation from outside bandage into wound

Question 10

wet to dry

Answer 10

sterile gauze soaked in sterile saline or sterile H20 +/- dilute antiseptic, cover with 2° absorptive layer, then 3° layer that allows evaporation

▪ Helps absorb wound fluid into outer layers
▪ After evaporation becomes hypertonic → draws wound fluid into dressing
▪ Change when contact layer is dry (~24 hrs)

Question 11

dry to dry

Answer 11

type of adherent dressing

sterile, wide-meshed dry gauze, cover with
secondary absorptive layer

▪ Wound fluid passes thru gauze → into absorptive layer ▪ Change once contact layer is dry

Question 12

advantages of non adherent dressing

Answer 12

Advantages
▪ Gas exchange with limited moisture loss
▪ Moist environment promotes epithelialization
▪ Can rehydrate dried necrotic tissue
▪ Concentrate growth factors at the wound surface
▪ Less damage to epithelium at dressing changes

Question 13

disadvantages of non-adherent dressing

Answer 13

Fluid accumulation can scald surrounding skin
▪ Hard to get to stick to haired areas
▪ Not good if grossly contaminated or infected

Question 14

when to use stent bandages

Answer 14

Padding laced over wound via skin sutures
- Areas not conducive to encircling bandage
▪ Upper limbs ▪ Trunk ▪ Head and neck
- Decrease wound tension

Question 15

splints should be positioned to counter ___

Answer 15

motion

- Radial nerve paralysis
- Two splints
▪ Lateral and caudal
▪ Hoof to elbow
- Goals
▪ Maintain carpal extension
▪ Prevent soft tissue trauma
▪ Prevent contracture

Question 19

level 3 injury splint in horse

Answer 19

▪ Flexors become abductors
- Medial soft tissue trauma
- Comminution
- Minimal medial soft tissue
or hip
- Goal: Prevent abduction
▪ Caudal splint – hoof to elbow
▪ Lateral splint – hoof to withers

Question 20

level 4 injury in horse
