functions of a soft tissue bandage

• Protects the wound from the environment and from the patient.

• Aids in debridement of the wound surface

• Manages exudate.

• Creates an environment for wound healing.

• Provides hemostasis.

• Decreases hematoma/seroma formation.

• Provides support and comfort.

• Delivers topical agents.

What are the two reasons bandages for

1. Management of soft tissue wounds

2. Stabilization of bone and joint injuries

What is the primary bandage layer

contacts the wound

Can be adhesive hypertonic or non-adhesive

what is the purpose of secondary bandage layer

Provides structure/absorbs/holds exudate

Cast padding or rolled cotton

what is the function of the tertiary bandage layer

conforms and holds secondary layer

Holds and protects the secondary layer

Rolled gauze/kling

Bandage occlusiveness that let's air, moisture, or other matter pass through

Non-occlusive

Bandage occlusiveness that Allows the wound to breath but protects the wound from moisture

Semi-occlusive

Bandage occlusiveness that maintains a moist wound

an occlusive bandage

When is an adherent primary layer used

for non-selective debridement in the inflammatory stage of the wound that is heavily contaminated

When is a non-adherent primary layer used

Used at the beginning of the PROLIFERATIVE STAGE to promote second intention healing

what does a non-adherent primary layer do

Effectively provides the same function as adherent bandage by providing a moist environment that supports effective phagocytic activity with significantly less trauma than the adherent primary dressing.

Semi-occlusive non-adherent primary layer

is permeable to air and fluid and permits exudate to be absorbed by the secondary layer

Occlusive non-adherent primary layer

is impermeable to air and retains moisture.

Hydrogels and hydrocolloids

can be used as semi-occlusive and occlusive primary layers.

Hypertonic saline and calcium alginates

are HIGHLY ABSORPTIVE primary layers.

Benefits of moisture retentive primary layer

• maintains a warm and moist wound environment

• Aids selective debridement

  • Improving epithelialization

What is the preferred primary layer of choice

moisture retentive primary layer

Hypertonic saline and calcium alginates do what

Draws fluid and debris away from wound, antimicrobial effect because of hypertonicity and low water content within wound

when are

Hypertonic saline and calcium alginates used

On highly exudative, contaminated, and infected wounds

Hydrogels, hydrocolloids and polyurethane film, or foam are used when

Best used on wounds with minimal exudate.

Can be used during inflammatory and repair stages of wound healin

what does Hydrogels, hydrocolloids and polyurethane film, or foam do

▪ Allow absorption of fluid while creating a moist wound healing environment.

▪ Supports cell activity and growth of granulation and epithelial tissue.

Example of a non adherent, non occlusive primary layer

Petrolatum-impregnated sterile gauze (Adaptic TM)

Teflon/ Telfa pads

Petrolatum-impregnated sterile gauze (Adaptic TM) is often used

in the proliferative wound phase.

Teflon (= ‘s “Telfa”) pads are commonly used to

cover surgical incisions and epithelialized skin.

FUNCTIONS OF AN ORTHOPEDIC BANDAGE

Stabilizes fractures or joints.

Maintains splints or casts in position.

Restrict motion.

Prevents weight bearing.

Protects soft tissues from further injury.

Decreases swelling.

what is the function of distal limb bandages

applied to protect wounds and to stabilize bone or joint injuries.

Splints, casts, and slings are used to provide further stability to orthopedic injuries or to prevent weight bearing.

ROBERT JONES BANDAGE

a distal limb bandage

Robert Jones is be used

to temporarily immobilize limbs distal to the elbow or stifle joints.

relies on an extremely thick secondary layer, such as cast padding or cotton, which is tightly compressed to cause uniform compression of the distal limb.

not commonly used on small animals

The modified Robert Jones bandage is

the MOST COMMONLY APPLIED DISTAL LIMB BANDAGE IN SMALL ANIMALS.

when are casts/splints used

To provide stabilization and support for joint injuries/fractures

For temporary support until surgery

As a means for definitive treatments

As an adjunct after surgical stabilization,

what material is preferred for casts

• Fiberglass cast material is preferred due to its light weight and strength.

where is a fiberglass cast applied

over the cast padding and gauze of a modified robert jones bandage

what materials are used for splints

prefabricated splints are made of plastic or aluminum

custom splints are made of fiberglass casting tape or thermoplastic material

where are forelimb splints applied

to the caudal limb surface

where are hindlimb splints applied

laterally

splints are placed over
