- Definition
- A wound is an injury to a tissue
- A wound ulcer is caused by pressure on the derma and underlying vascular structure
- Types of wound
- Closed wound: the surface of the skin is intact, but the underlying tissue may be damaged
- Open wound: the skin is split or cracked and the underlying tissue is exposed to the outside environment
- Stages of wound healing
-
Inflammatory phase:
- it's characterized by the vasodilation released of histamine and stimulation of nacioreceptor
- This can be present with redness, heat, swelling, pain
-
Proliferation phase
- It's characterized by the formation of granulation tissue
- The wound contracture starts in this phase
- The fibroblasts in the wound develop into collagen Matrix
-
Maturation or remodeling phase
- Remodeling of epithelial Starts
- it's an ongoing process even after wound closure takes months to years
- PT intervention starts in this stage
-
Clinical presentation
- Redness, change in skin temperature, swelling loss of skin thickness, and bleeding in an open wound
-
Before PT intervention (wound examination)
- History
- History is taken to determine the primary problem
- History should start from the mechanism of injury, date of onset, progression
- Treatment history to date
- History of the previous wound
- Co-morbidities: vascular disorder, diabetes, cancer
- Subjective examination
- To gather information on current symptoms
- Patients should be questioned about behavior and characteristics of symptoms
- Objective examination
- Here observation is the most important component of data collection, it includes the type of lesions
- It includes stages of wounds
- History
-
Aim of treatment
- enhance clotting time and bleeding time
- Teach the patient self-care for wounds and identification of signs of infection
- Reduce the necrosis tissue at the normal site
- Decrease the pain associated with the wounds and risk of infection
- Improve the physical function of the wound site
How do modalities help in wound healing (PT treatment)
-
Ultrasound therapy
- When ultrasound is applied in the inflammatory stage.
- It enhances the degranulation of mast cells, releasing histamine and other mediators that attract fibroblasts and endothelial Cells to the injured area.
- Early intervention with ultrasound should result in an accelerated acute inflammatory phase moving to a more quick entry into the proliferative phase and improving the wound.
- In the Proliferative stage, ultrasound stimulates fibroblast migration and proliferation to secrets Collagen, improving the tensile strength of the healing Connective tissue
- In the remodeling phase, Collagen extensibility and ultrasound increase enzyme activity and also improve the tensile strength of the healing tissue
- Doses- 3-4 times a week.
- For superficial wound: 3MHz
- Deep wound: 1MHz
-
LASER
- Laser light stimulates fibroblast development and accelerates collagen synthesis in damaged tissue for faster recovery
- Laser light accelerates cellular reproduction and growth to improve the speed of healing time. Laser light induces vasodilation increasing blood flow to damaged areas.
-
UVR
- Increase the amount of fibronecting present in the wound environment, Potentially improving the microenvironment for cell migration,
- And also Stimulates contraction thus decreasing the size of the wound It stimulates cell hyperplasia.
- Improve Skin Condition by increasing blood Supply Destroy and remove infected material.
-
Whirlpool bath
- Treat wounds with loosely adherent necrotic tissue or thick exudates. facilitates debridement in infected wound
- Decrease wound pain
- The warmth of water increases blood circulation to the Wound surface.
- Doses - daily for 20 minutes at 33-35°C. Once daily
-
Electrical Stimulation
- Electrical Stimulation has effectiveness in facilitating healing in both acute and chronic wounds.
- It is used to eliminate bacterial load, Promote granulation, reduce inflammation, and edema, and reduce wound-related pain.
- Using high voltage Pulse current directly in the wound can create these changes - attraction of neutrophils, macrophages, and epidermal cells which facilitate debridement and re-epithelialization.
- Electrical stimulation has a galvanotaxic effect on the Cells needed for healing
-
Infrared radiation
- It increases local wound and skin temperature facilitating metabolic rate and improving circulation to the wound site.
- Increases local circulation in nitric oxide leading to vasodilation Indications venous ulcers, diabetic ulcers
-
Compression therapy.
- It is a goal standard treatment for venous ulcers it decreases Chronic oedema and lymph edema.
- Compression bandaging needs to be applied by skilled Practitioners and experts.
- It tackles symptoms of assisting venous insufficiency by assisting venous blood flow back to the heart.
- Greater pressure is applied at the ankle and gradually increases Circulation and prevents edema in the veins of the lower limb.
-
Prevention of wound ulcer
- Air mattress- It Presents infection since dirt and dead skin can't Penetrate water. Healing is 3 times faster in those who already have an ulcer
