Study Notes
Surgical Supplies by Pharmacist
- A pharmacist's role in surgical supplies involves providing instruments, sutures, surgical dressings, and equipment used before, during, and after surgery.
- Pharmacists must have the ability to select the right instruments to ensure patient safety and well-being during the surgical procedure.
Surgical Dressings
- Surgical dressings are materials used to cover wounds, injured or diseased tissues, promoting healing and safety.
- Key properties of surgical dressings include:
- Creating a moist environment
- Preventing maceration of exudative wounds
- Protecting from dehydration, mechanical or chemical damage, microbial invasion, and pH alteration
- Facilitating healing
- Providing support
- Reducing overall costs
Types of Surgical Dressings
- Surgical dressings are classified based on:
- Degree of exudation
- Presence or likelihood of infection
- Presence of necrotic tissue
- Anatomical sites
- Types of surgical dressings include:
- Primary wound dressings
- Secondary wound dressings
- Adhesive tapes
Primary Wound Dressings
- Primary dressings are applied directly to the wound.
- They provide:
- Absorptive capacity
- Prevention of desiccation
- Protection from infection
- Prevention of secondary dressing adhesion to the wound
- Types of primary wound dressings:
- Plain gauze
- Impregnated gauze
- Film dressings
Plain Gauze
- Used for exudative, infected, and necrotic wounds.
- Can stick to the wound, making removal painful.
Impregnated Gauze
- Impregnated with substances to reduce adherence to wounds.
Film Dressings
- Transparent, occlusive, or semi-occlusive.
- Made of polyurethane with acrylic or polyether adhesives.
- Suitable for exuding wounds.
- Disadvantage: Can wrinkle, creating entry points for microbes.
Secondary Wound Dressings
- Placed over primary dressings to provide additional protection, absorbency, compression, or occlusion.
- Types of secondary wound dressings:
- Absorbents
- Bandages
- Adhesive tapes
Absorbents
- Subtypes:
- Nonabsorbent unbleached cotton
- Nonabsorbent bleached cotton
- Absorbent cotton
- Rayon
- Surgical gauze
- Film-coated gauze
- Nonwoven surgical sponges
- Medicated surgical gauze
- Selvage-edge gauze strips
- Gauze pads or sponges
- X-ray detectable gauze pads
- Sanitary napkins
- Disposable under pads
- Disposable cleaners
- Eye pads
- Nursing pads
Bandages
- Subtypes:
- Gauze roller bandages
- Muslin bandage rolls
- Elastic bandages
- Woven elastic bandages
- Crepe bandages
- High bulk bandages
- Triangular bandages
- Orthopedic bandages
Adhesive Tapes
- Subtypes:
- Acrylate adhesives
- Rubber-based adhesives
Combined Primary-Secondary Wound Dressings
- These dressings combine primary and secondary dressing functions.
- Types:
- Hydrogels
- Hydrocolloid dressings
- Calcium alginate dressings
- Protective products for adhesion prevention
Hydrocolloid Dressings
- These dressings are opaque or transparent.
- They are biodegradable, breathable, and adhere to the skin, eliminating the need for separate taping.
- The dressing's surface is coated with a cross-linked adhesive containing gelatin, pectin, carboxymethyl cellulose, polymers, and adhesives.
- When in contact with wound exudate, the polysaccharides and polymers absorb water, forming a gel, which can either drain or remain within the adhesive matrix.
- The moist environment promotes fibrinolysis, angiogenesis, and wound healing without damaging tissue.
- Most hydrocolloid dressings are waterproof.
Calcium Alginate Dressings
- These dressings are made of natural fibers from seaweed.
- They are highly absorbent.
- They absorb wound exudate, forming a gel-like covering over the wound.
- They help maintain a moist healing environment, promote healing, and minimize bleeding.
- The gel-like surface prevents the dressing from adhering to the wound.
