Study Notes

NUR 1012 Fundamentals of Nursing I: Principle of Asepsis and Wound Care

This course covers wound care and the principles of asepsis.
Learning objectives include describing wound types and phases of healing, factors affecting healing, and common dressing materials.
Wound care procedures, including obtaining cultures and removing sutures/staples, are also addressed.

Skin

The skin is the largest organ in the body.
Functions include protecting from external factors (bacteria and chemicals), sensing touch, heat, and cold, preventing excessive water loss, and synthesizing Vitamin D.
Excretion (sweat) is a function of the skin.
Cutaneous refers to the skin.

Skin Layers

Layers of skin include epidermis, dermis, and subcutaneous tissue.
Contains sensory nerve endings, hair, and glands.

Wound Classification

An intact skin has normal skin and skin layers, not interrupted.
A wound is a break or disruption in the normal integrity of the skin and tissues.
Wound classification criteria include onset/duration (acute/chronic), depth (superficial/deep), pressure (staging, 1-4), and clean/contaminated.

Wound Types

Common wound types include abrasion, laceration, puncture, incision, and contusion/hematoma.

Wound Healing Stages

The stages of wound healing are: Bleeding/Hemostasis, Inflammation, Proliferation, and Remodeling/Maturation
Each phase has specific characteristics and cellular processes involved.

Factors Affecting Wound Healing

Factors influencing wound healing include infection, foreign body, venous insufficiency/ischemia, age, stress, comorbidities (diabetes, autoimmune diseases), obesity, medications (NSAIDs, chemotherapy), alcoholism/smoking, immunocompromised conditions, and nutrition.

Aseptic Principles

Concepts relating to asepsis include dirty (presence of microorganisms in large numbers), clean (reduced number), and sterile (free from microorganisms).
Sterility is essential in clinical settings, especially during wound care.
Sterile objects become unsterile when exposed to unsterile objects/environments.

Principles of Asepsis

All objects in a sterile field require sterility, checking for intactness, sterility indicators, dryness, and expiry date.
Discarded if opened, torn, punctured, wet, expired.
Store in dry, clean areas, off the floor.
Sterile objects become unsterile if improperly handled or exposed. Proper handling and use of sterile forceps or gloved hands is vital.
Airborne microorganisms can contaminate a sterile field.
Minimizing unnecessary traffic and maintaining proper procedures are important.
Fluid flows in the direction of gravity.
Moisture can carry microorganisms.
Skin cannot be sterilized; hand hygiene is used to reduce microorganisms.
Sterile fields must be properly maintained, not used prematurely, or improperly exposed.
Guidelines and precautions relating to sterile field maintenance.

Wound Dressing Solutions

Solutions include normal saline (0.9% sodium chloride/NS), aqueous hibitane (chlorhexidine gluconate 0.05%), and povidone-iodine.
Each has specific properties and uses in wound care.

Wound Dressing Materials

Dressing materials are used for wound protection, absorbing drainage, maintaining moisture, preventing/controlling infections, and removing necrotic tissue.
The choice of dressing depends on location, size, wound type, exudate amount, debridement or infection/purpose, and frequency of dressing changes.
Examples include gauze, transparent films, mesh films, foam dressings, alginates, hydrocolloids, and hydrogels. This list does not include all possible materials.

Wound Assessment

Assessing wound location (anatomic location, left/right), cause (burn wound, wound from circulation insufficiency, poor medical control), type (clean surgical, trauma, pressure injury), size (measurements, methods like using probes/applicators), exudate (amount, type which can range from none to heavy), and wound bed (condition) are all critical components for assessment.

Wound Packing

Wound packing prevents premature wound closure by absorbing drainage, promoting inside-out healing, and reducing the risk of infection.
When packing a wound, use clean dry gauze and ensure the packing is not too tight to avoid pressure on the wound bed and maintain healing. Keep a sufficient tail of packing material outside the wound.

Wound Irrigation

Wound irrigation removes foreign material, decreases contamination, removes cellular debris/exudate, and cleans the wound.
Sterile syringes, angio-catheters, sterile gloves, and a waterproof drape for the procedure are necessary.

Drain Care

Drains are used to manage fluid buildup, preventing infection from delayed wound healing, removing wound fluid deposits from tissue, and allowing for dressing changes.
Types of drains include open systems (Penrose drain), closed systems (Jackson-Pratt drain).
Care of the drainage system, its tubing, and the affected skin is critical for healing
Wound drainage should be monitored, and appropriate preventive/corrective actions taken.

Wound Closure

Wound closure methods may include sutures, staples, or medical glue.
Considerations for selection include wound location, nature of the wound, and age.
Wound closure techniques and selection.

Wound Culture

The purpose of a wound culture includes identifying the microorganisms causing an infection, evaluating the sensitivity of the infecting organisms to different antibiotics, and assisting in the development of effective treatment regimens based on this sensitivity testing.
Proper procedure for collecting, handling, and sending wound cultures are needed, ensuring no contamination during the process.

Wound Assessment and Management Chart

Wound assessment and monitoring tools are discussed, including those using numerical rating scales for pain.
This chart and its use in wound care management are emphasized, including record-keeping details to accurately track and document the wound condition over time. This is a crucial wound care resource and should be familiar to students.
