Surgical Wound Care

1. Surgical Wound Care

2. “Wound” • Refers to any injury to the body’s tissues involving a break in the skin. •  Promoting wound healing is the nursing focus during the postsurgical recovery phase • Patient-related factors influence wound healing: • age, nutritional status, physical condition, pre-existing health status, and medication habits

3. Wound Classification • Vitally important to understand the causative factors of a wound to determine the proper treatment plan • In a planned surgery, a cut (incision) is made by a sharp instrument creating an opening into an organ or space in the body; or • A stab wound (puncture) for a drainage system

4. Surgical Wound • Selection of the site for the surgical wound is based on • Tissue/organ involved • Nature of injury/disease process • Process of inflammation/infection • Strength of the site • If a drainage system is required, the position of the drain may also influence the placement of the incision. • Could be surgeon specific

6. Wound Healing • Healing process begins immediately after an injury and sometimes continues for a year or longer • Follows 4 phases: • Hemostasis • Termination of bleeding • as soon as the injury occurs • Platelets adhere to the walls of the injured vessel  formation of clot  fibrin in the clot begins to hold the wound together

7. Wound Healing • Inflammatory Phase • Increase in blood elements and water flow out of the blood vessel into the vascular space  Causes cardinal signs and symptoms of inflammation: -erythema -heat -edema -pain -tissue dysfunction

8. Wound Healing 2. Inflammatory Phase cont. • Leukocytes engulf bacteria, fungi, viruses, and toxic proteins • Cells in the injured tissue migrate, divide, and form new cells • Blood clots dissolve • Wound fills

9. Wound Healing 3. Reconstruction Phase • Collagen formation occurs (glue-like protein substance) -adds tensile strength to the wound/ tissue. • Irregular, raised, purplish, immature scare • Wound dehiscence risk • Angiogenesis • -formation of new vasculature

10. Wound Healing • Remodeling Phase (maturation) -Collagen deposition -peaks by the third week -Remodeling -can last for years after the initial injury -collagen is degraded and deposited in an equilibrium-producing fashion -no change in the amount of collagen present in the wound.

11. Process of Wound Healing • Wounds close by: primary intention, secondary intention, or tertiary intention • Primary Intention • Wound is made surgically with little tissue loss. • Skin edges are close together. • Minimal scarring results.

12. Process of Wound Healing • Secondary Intention • When a wound must granulate during healing • Occurs when skin edges are not close together or when pus has formed • Surgeon may treat with a drainage system or by packing the wound. • This gives decomposed necrotized tissue an escape. • Cavity begins to fill with granulation tissue. • Scarring is greater in a larger wound.

13. Process of Wound Healing • Tertiary Intention = delayed primary intention • Contaminated wound is left open -sutured closed after the infection is controlled • Also occurs when a primary wound becomes infected -opened -allowed to granulate -sutured

14. Keloids • -Abnormal scar that grows beyond the boundary of the original site of a skin injury – overgrowth of collagenous scar tissue • -Some ethnic groups are at more risk • -highly pigmented ethnic groups other than Caucasians. • Parts of the body affected • -upper arm, • -upper back/sternum. • -earlobes/back of the neck • Other causes • Infection at a wound site, repeated trauma to the same area, skin tension or a foreign body in a wound can also be factors.

15. Factors Affecting Wound Healing • Nutritional Needs • -provide small frequent feedings • -total parenteral nutrition • -nasogastric feedings • Hydration • Offer hourly; encourage 2000 to 2400 ml in 24 hours. Intracellular Fluid accounts for 2/3 of the fluid in the body.

16. Factors Affecting Wound Healing • Blood Supply • Poor circulation • Age • Lower metabolic state in the elderly • Specialized tissue • Muscle and Nerve tissue do not regenerate easily • Infection • Interferes with the matrix formations • Rest • Periods of sleep aid in healing

17. Surgical Wound • Surgeon’s goal -enter the cavity involved -repair the injured/diseased area -minimize trauma as quickly as possible. • Wound • A disruption of the skin integrity • Tissue has been disrupted so severely that it cannot heal naturally without complications or disfigurement • held in approximation until the healing process provides the skin with sufficient strength to withstand stress without mechanical support

18. Wound Closure • Wound closure material and techniques of using them: • Prime factors in the restoration and tensile strength of the healed tissue. -staples -sutures -clips -skin closure strips -topical adhesions

22. Wound Closures • Transparent Dressings • Self-adhesive transparent film -synthetic permeable membrane (breathe-able) -temporary secondary skin. • Advantages • contains exudates/minimize wound contamination • barrier to external fluids and bacteria yet still allows the wound to breathe • moist environment that speeds epithelial cell growth • visualization of the wound

23. Transparent Dressing

24. Liquid Bandage Transparent Dressings

25. Care of the Incision • Surgical wounds -generally heal well and quickly -dressing may be removed within 24 – 72 hours -allow air circulation -trend – to leave sutured, clean wounds not dressed after surgery or use loose dressing • Incision Coverings • Gauze • Permits air to reach the wound • Semi-occlusive • Permits oxygen but not air impurities to pass • Occlusive • Permits neither air nor oxygen to pass

26. Care of the Incision • Securing a dressing: • Tape • Ties • Bandages • Cloth binders • Choice of anchoring depends on: • Wound size • Location • Presence of drainage • Patient’s level of activity

27. Care of the Incision • Removing Dressings • Avoid accidental removal/displacement of underlying drains. • Analgesic may need to be given at least 30 minutes before the dressing change • Sterile technique • Gown, mask, and protective goggles -if soiling or splashing of wound exudate is expected.

28. Dry Sterile Dressings (DSD) • For managing wounds with little exudate or drainage -keep wound dry to prevent excoriation. • protects from injury, prevents introduction of bacteria, reduces discomfort, and speeds healing • For Abrasions/non-draining postoperative incisions

29. Remove old dressing and use gloves to contain old dressing and drainage. Wash hands before and after removing dressing After washing your hand, put on new gloves. Wash wound with SNS, working from incision outwards. Use a new 2X2 each time you return to center. Apply appropriate dressing. You could consider Montgomery Straps if you are changing dressing frequently. Changing a sterile dry dressing.

31. Bandages and Binders • Bandage • -strip or roll of cloth/other material -wrapped around a part of the body in a variety of ways -multiple purposes. -rolls of various widths/materials -gauze, elasticized knit, elastic webbing, flannel, and muslin. • Binders • -large pieces of material to fit a specific body part -abdominal binder or a breast binder.

32. Bandages and Binders • Before a bandage or binder is applied • Inspect the skin for abrasions, edema, discoloration, or exposed wound edges. • Cover exposed wounds or open abrasions with sterile dressings. • Assess the condition of underlying dressings and change them if soiled. • Assess the skin and underlying body parts and parts that will be distal to the bandage for signs of circulatory impairment.

33. Bandages and Binders • Correctly applied bandages and binders do not cause injury to underlying and nearby body parts or create discomfort for the patient.

35. Cloth Binders (Do they exist?)

38. Care of the Incision • Wet-to-Dry Dressing • Primary purpose-mechanically debride a wound. • Moistened contact layer of the dressing collects exudate and wound debris. • As the dressing dries, it adheres to the wound and debrides it when the dressing is removed. • Normal saline and lactated Ringer’s solution, acetic acid, sodium hypochlorite solution, povidone-iodine, and antibiotic solutions.

39. Wound Irrigation • Irrigations • Wound cleansing and irrigation • Sterile or clean technique. • Introduced directly into the wound • Syringe, syringe and catheter, shower, or whirlpool • Position the patient on his or her side to encourage the flow of the irrigant away from the wound • Removes debris from a wound surface, • Decreases bacterial counts • Loosens and removes eschar.

40. Wound Irrigation • Solutions used for irrigations include warm water, saline, or mild detergents. • Principles of Basic Wound Irrigation • Cleanse in a direction from the least contaminated area to the most contaminated area. • When irrigating, all of the solution flows from the least contaminated area to the most contaminated area.

41. Complications of Wound Healing • Impaired wound healing requires accurate observation and ongoing interventions. • Wound bleeding potentially indicates: -slipped suture -dislodged clot -coagulation problem -trauma to blood vessels or tissue. • If internal hemorrhage occurs, the dressing may be dry while the abdominal cavity collects blood.

42. Complications of Wound Healing • Wound Infection • Results when the wound becomes contaminated. • “infected” when it contains purulent (pus) drainage. • elevated WBC count. • Purulent drainage -odor -brown, yellow, or green -depending on the pathogen.

43. Cardinal Signs of Infection and Inflammation • Erythema • Edema • Heat • Pain • Purulent drainage • Loss of function

44. Complications of Wound Healing • Dehiscence • Wound layers separate. • Patient may say that something has given way. • Result after periods of sneezing, coughing, or vomiting. • Preceded by serosanguineous drainage. • Patient should remain in bed and receive nothing by mouth, be told not to cough, and be reassured. • The nurse should place a warm, moist sterile dressing over the area until the physician evaluates the site

45. Complications of Wound Healing • Evisceration • Abdominal organs protrude through an opened incision. • Patient is to remain in bed, and the wound abdominal contents should be covered with warm, sterile saline dressings. • The surgeon is notified immediately. • This is a medial emergency, and the wound requires surgical repair.

46. Staple and Suture Removal • Physician’s written order • The time of removal -based on the stage of healing and extent of surgery. • 7 to 10 days after surgery, or sooner if healing is adequate. • Leaving in a suture too long -removal more difficult and increases the risk of infection. • One at a time -removal of every other suture or staple and replaced with a Steri-Strip as the first phase, with the remainder removed in the second phase.

47. Staple and Suture Removal • Sutures • Sutures are threads of wire or other materials • Sutures are placed within tissue layers in deep wounds and superficially • Deeper sutures are usually made of absorbable material • Types include interrupted or separate sutures, continuous sutures, blanket sutures, and retention sutures covered with rubber tubing for strength.
