What are the three types of wound classifications?
Abrasions, Punctures, Lacerations
What is an Abrasion?
rubbing or friction injury in the epidermis
What is a Puncture?
sharp object pierced epidermis, may reach dermis or deeper tissue
What is a Laceration?
sharp object cutting through various skin layers
What is Stage I of clinical presentation of wounds?
Intact and unbroken skin, erythema, redness, - Minor or superficial burns
What is stage II?
Superficial lesions, partial thickness skin loss, only epidermis involved - Abrasions, superficial lacerations or punctures
Stage III
Full thickness skin loss, epidermal + dermal involvement with damage to subQ tissue - Lacerations and punctures, Stage III ulcer
Stage IV
Full thickness skin loss, involves subQ tissues, underlying muscle, tendon, and bone - Deep laceration, deep puncture wound, Stage IV ulcer
What are the pathophysiological wound healing phases?
I. Inflammatory II. Proliferation III. Maturation or remodeling
What are some delayed healing disease states?
-DIABETES - Severe anemia - Hypotension - PVD - CHF
What are the delayed wound healing medications?
Antiplatelets Glucocorticosteroids Systemic steroids (these interfere with the inflammation phase) Chemotherapeutic drugs (cell division)
What are some causes of delayed wounds healing?
Inadequate nutrition Advanced age and obesity
What is the goal for treatment of minor wounds? Stepwise self treatment approach?
CSC
Self care vs. referral Relieve symptoms, promote healing by protecting the wound from infection and further trauma and minimize scarring 1) Cleanse damaged area 2) Selectivity use antiseptics and antibiotics 3) Close or cover with appropriate dressing
What are the exclusions for self care for a wound?
-Wound containing foreign matter after irrigation • Chronic wound • Wound secondary to an animal or human bite • Signs of infection • Involvement of face, mucous membrane, or genitalia • Deep, acute wound • Patients with diabetes
What is the new non pharm approach to treat wounds
Create moist wound environment - Reduces loss of protein, electrolytes, fluid from wound to help minimize pain and infection – Removes excess exudate without dehydration of wound – Prevents rapid eschar formation – Prevents bandage adherence to wound and damage to new tissue – Promotes healing
What are the advantages of gauze for dressing a wound?
Readily available in many sizes and forms, affordable, can combine with other topical products
What are liquid bandages used for?
For minor cuts - close the wound - help stop bleeding - prevent infection and reduce pain best for hard to bandage areas
What are the pharmacological recommendations for wound care?
Systemic Analgesics - NSAIDS - anti-inflammatory - Acetaminophen Topical Analgesics - Inhibit transmission of pain signals from pain receptors: duration 15-45 minutes - Common ones are lidocaine and benzocaine High concentration when skin is intact Low when skin surface is not intact
Talk about First-Aid antibiotics what if you use it for too long?
It is a triple antibiotic cream or ointment containing - Bacitracin - Neomycin - Polymyxin If use is prolonged bacterial resistance may be developed and may cause secondary fungal infection
If sign of improvement are not seen within how many days? what should you do?
Constipations i think
If not improved within 7 days then refer to the doc
What are the exclusions for self treatment when treating corns or calluses?
- Diabetes - PVD - Lesions hemorrhaging or oozing purulent material - Anatomic defect - Extensive or painful - Unsuccessful self treatment attempt - History of RA
What is the pharmalogical therapy of corns and calluses?
Salicylic Acids
Callodion and Liquid forms of salicylic acids are in what concentration?
12-17.6%
Plaster and disk, pads forms of salicylic acids come in what concentration?
12-40%
