30 30 Spinal Traction Where are the knots? Are the weights hanging free? What do the pin sites look like? How do I turn the patient? How can I make the patient comfortable?

31 31 Complications Compartment syndrome Fat embolism DVT Osteomyelitis Aseptic necrosis

32 32 Compartment Syndrome Prevention oCheck CSM oIce, elevate oLoosen dressing, open cast Emergency care oFasciotomy:

33 33 Fat Embolism Long bones, multiple fractures Elderly: hip fractures Altered mental status Respiratory distress Petechiae on trunk Prevention: early immobilization of fracture

34 34 Deep Venous Thrombosis Most common complication Predisposing factors Common sites: leg, pelvic fx Pulmonary embolus prevention Deep Vein Thrombosis Source: National Heart & Blood Institute

35 35 Osteomyelitis Sources: open wounds, implanted hardware Staphylococcus aureus usually Rx: IV antibiotics

36 36 Aseptic Necrosis Death of bone tissue Hip fractures or bone displacement Hardware interferes with circulation

37 37 Amputation Diabetic, smoker, infected foot ulcer Trauma Grieving loss Altered self concept Coping Family response

38 38 Surgical Wounds Web Resource Click tab titled, Med-Surg 1 Drop down menu choose Wound Care

39 39 Wound Assessment Measure the wound in centimeters Assess phase of wound healing Reaction Regeneration Remodeling Wound location, color of wound bed, condition of wound margins, integrity of surrounding skin Signs and symptoms of infection Drainage: amount, color, consistency, odor

40 40 Wound Care Dressing The ideal dressing oKeeps wound moist oPrevents maceration oProtects from contamination oContains wound fluid oProtects granulation tissue

41 41 Traditional dry dressings oWounds exposed to air are more inflamed, painful, itchy and have thicker crusts than moist wounds oEpithelium migrates into wound bed: if must burrow between any eschar (crust or Wet to dry dressing significantly increase healing time oNonocclusive: increased risk of contamination and infection

42 42 Moist Wound Healing No eschar develops (crust, scab) Enhances autolytic debridement: promotes role of macrophages and leukocytes Bacterial barriers: prevent wound contamination Wound fluids kept at site: contain growth factors and enzymes that promote autolysis and healing

43 43 Potential for Infection Signs of infection –I-induration –F-fever –E-erythema –E-edema

44 44 Absorptive powders and pastes Used in heavily draining wounds: absorb up to 100x weight in fluid: may increase wound pH above physiological levels May require wrapping in gauze before inserting into wound bed Pastes easier to remove from wound

45 45 Wound Healing Normal healing (3R's) oReaction: inflammatory process (72 hours) oRegeneration: proliferation (up to three weeks) oRemodeling: (three weeks to two years)

46 46 Black Wound = Eschar Cellular debris will escape wound edges as necrotic tissue begins to separate from granulation tissue If eschar becomes contaminated: becomes excellent medium for infection wound remains in reaction or inflammatory stage systemic signs of infection Eschar delays regeneration phase by interfering with cell migration and wound closure Risk of wound infection increases as the amount of necrotic tissue increases Needs debridement

47 47 Yellow Wound Tissue not damaged enough to form an eschar so wound covered with thick yellow fibrous debris or viscous exudate oHigh risk of infection due to excellent medium for bacterial growth oNeeds continuing debridement Photo courtesy of Saddleback College, California,

48 48 Red Wound Red indicates presence of granulation tissue. oColor of granulation tissue affected by nutritional status and blood supply full thickness ulcer: crater with pale pink to beefy red granulation tissue crater slowly fills with granulation tissue from bottom upward oWound contraction and epithelialization continues. Epithelialization occurs from wound edges inward.

49 49 Wound Drainage Devices Decrease pressure in the wound by removing excess exudate thereby promoting healing from the inside (secondary healing). Examples: Penrose drain, Jackson- Pratt & Hemovac suction devices

50 50 Dehiscence/Evisceration Partial or complete separation of the outer wound layers. If the internal organs below the wound protrude out of it, the wound has eviscerated. Highest risk is in obese patients, diabetics or those receiving steroids.

51 51 Bacterial skin infections Folliculitis, furuncles, cellulitis: these infections are usually caused by Staphylococcus aureus. Folliculitis involves the hair follicle. Furuncles (boils) are deeper. Cellulitis is a general infection and involves deeper connective tissue. Topical antibiotics: Neomycin sulfate (Neosporin) Teach: wash area daily with antibacterial soap, allow skin to dry, prevent cross contamination

52 52 Herpes Simplex Virus Type 1 causes common cold sore, type 2 causes genital herpes. After first infection, recurrence is triggered by stress. Spreads by direct contact. Patient is contagious for the first 3-5 days. Topical acyclovir (Zovirax) shortens the period of infection

53 53 Herpes Zoster (Shingles) Caused by reactivation of varicella (chickenpox). Occurs in the dermatome corresponding to the infected nerve. Eruptions follow several days after pain in the area, last several weeks. Acyclovir (Zovirax), given topically and/or orally controls the severity of the lesions and decreases pain.

54 54 Acute Burns

55 55 Superficial Sunburn oEpidermis pink to red oMild edema oPainful oHealing time: 3-5 days oNo skin graft

56 56 Partial Thickness Burn Brief contact: scald, flames, grease, chemicals Epidermis and dermis damaged Blisters if mild burn, pale, mottled, waxy white with deeper Painful Healing time: 2-6 weeks No grafting unless healing prolonged

57 57 Full Thickness Burn Prolonged contact: scald, flame, tar, grease, chemical, electricity Epidermis, dermis & underlying tissues damaged Waxy white, dry, leathery, charred No pain Healing: Weeks to months Skin grafts required

58 58 Percentage of Burn Injury Source: Burn diagrams courtesy of BioTel Emergency Medical Service (EMS), Texas Department of Health,

59 59 Emergency Management Excessive leakage of plasma, especially in the first eight hours post-burn, causes hypovolemia, hypoproteinemia, hemoconcentration, electrolyte imbalances and acid base disturbances. In the absence of prompt fluid replacement, burn shock is imminent.

60 60 Fluid Resuscitation Initial 24 hours: Lactated ringer's 2-4 ml/kg/%burn/24 hours - given in the first 8 hours post- injury. Additional fluid required for inhalation injury. Maintain urine output of 30 ml/hr. 5% albumin – keep albumin >2.5 gm/dl

61 61 Monitoring Fluid shift lasts 24 to 72 hours. Hematocrit, electrolytes, osmolality, calcium, glucose, albumin Urine output >30 ml/hr Myoglobinuria and hemoglobinuria Pulse rate and pulse pressure Normal sensorium and adequate peripheral capillary refill

62 62 TypeCausePriority ThermalFlame, steam, liquidsSmother flames; Remove smoldering clothing & metal objects ChemicalAcids, strong alkalis, organic compounds Brush off dry chemicals Remove clothing; ascertain type of chemical ElectricalDirect or alternating current Lightning Separate patient from electrical current Smother any flames Start CPR; Obtain EKG RadiationSolar, X-rays Radioactive agents Remove from radiation source Remove clothing if contaminated using tongs or lead gloves Send to radiation decontamination center

63 63 Skin Care Hydrotherapy daily to debride eschar and cleanse wounds Topical enzyme such as collagenase (Santyl) or Accuzyme will debride more rapidly Silver coated anti-microbial dressing (Acticoat)

64 64 Grafting: Allograft (skin from a cadaver) Synthetic such as Biobrane Bioengineered skin substitute (Transcyte)

65 65 Prevention of Pressure Ulcers Patients at risk Inspect skin frequently Move at least every 2 hours Use life sheet or slide board Pad bony prominences Remove excess moisture Adequate nutrution Use protective barriers
