- 4. Application of heat and cold therapy • Heat and cold therapy are frequently used in the treatment of a variety of musculoskeletal disorders, especially when the patient has experienced trauma. • Heat therapy is used to promote healing, decrease pain, and support the inflammatory process. • The local application of heat causes vasodilation in the area where the heat is applied. • The vasodilation effect leads to an increase in tissue metabolism and an increase in capillary permeability.
- 5. • As a result, there is increased blood flow to the area that brings nutrients to the injured tissues and removes waste materials. • Because of the increased blood flow, venous congestion in the injured area is decreased, which helps decrease edema. • The warmth of the heat therapy also relaxes muscles and decreases the pain that may occur due to muscle spasms
- 6. • CONDITIONS TREATED BY HEAT THERAPY 1. Muscle strain 2. Low back pain 3. Arthritis 4. Osteomyelitis 5. Joint pain 6. Edematous area
- 7. • Cold therapy is used to decrease pain and minimize the development of edema. • The local application of cold causes vasoconstriction in the areas where the cold is applied. • As a result, the blood flow to the area is reduced, thus decreasing the development of edema. The cold also produces a local anesthetic effect, which decreases the sensation of pain.
- 8. • CONDITIONS TREATED BY COLD THERAPY 1. Arthritis 2. Fractures 3. Sprains and strains * 4. Muscle spasms 5. Joint injury*
- 9. • Heat therapy should not be applied to any area that is actively bleeding. • The heat must be carefully regulated to avoid burning or blistering the skin. • The patient should be cautioned not to increase the temperature setting. • Prolonged application of heat should also be avoided because after about 1 hour of application, a reflex vasoconstriction will develop.
- 10. • Cold therapy should not be applied to any area that has already developed edema. • The vasoconstriction that occurs as a result of the cold decreases circulation and will hinder the removal of excess fluid from the tissues. • Cold therapy can also cause tissues to freeze if the skin is not carefully protected from the cold source. • Prolonged application of cold should be avoided as it can lead to reflex vasodilation.
- 11. • Skin that is developing damage from the cold application will initially look red and then become mottled in appearance. • The patient may complain of burning pain and numbness in the area
- 12. Care of the patient with the a cast • Casts, which are a type of external fixation device, are used to immobilize a specific area of the body that has been injured. • Most frequently used to immobilize fractures, casts may also be used to treat soft tissue injuries. • The application of a cast stabilizes the injured area and prevents movement so that healing can occur, while typically allowing the patient to retain mobility
- 13. • Casts are made of various materials and thickness. • The choice of cast will depend upon the condition being treated. • The cast will usually extend from the joint proximal to the injury to the joint distal to the injury, so that complete immobilization of the injured area can be accomplished
- 14. • Short arm casts are used to immobilize wrist or metacarpal fractures. • Long arm casts are used to immobilize elbow and forearm fractures. • Short leg casts are applied to ankle and foot injuries, while long leg casts are used to immobilize a fractured tibia or knee injury. • Long leg casts may also be used for unstable ankle fractures.
- 15. • Body jacket casts are used to stabilize thoracic or lumbar spinal injuries. • The hip spica cast is used to immobilize femoral fractures and is frequently used in children. • The spica cast may be single or double depending upon the location and extent of the fracture
- 16. • Casts can also be used as splints where they are used to immobilize a body part without completely encasing it. • Cast braces, which permit joint mobility, can also be used. With a cast brace, two casts are made — one for application above a joint and one for application below a joint. • The two casts are joined together by hinges that permit mobility of the joint
- 18. • Application of the Cast • Following the reduction of the fracture, a cast will be applied. • the type of material used to make the cast may be of plaster or various synthetic materials such as fiberglass or plastic.
- 19. • Plaster is the traditional casting material and is relatively inexpensive. • It is also heavier and takes longer to dry after application. • Plaster must be kept dry after application. • The fiberglass or synthetic materials are lighter in weight, quick to dry, and can tolerate submersion in water without loss of form or strength. • the type of cast material selected will depend upon the type of injury. Synthetic casts are more suitable for simple, non-displaced fractures that have little swelling. They also hold up well for long-term use.
- 20. • The casting materials are available in individual rolls. The rolls are individually submerged in water until they are wet and then unrolled and wrapped around the injured body part. • The wrapping process s similar to applying an Ace wrap or other circular bandage. • The number of wraps or layers of material will determine the ultimate strength of the cast. • As the material begins to dry, heat is generated and felt by the patient.
- 21. • Prior to the application of a cast, the nurse may be responsible for preparing the patient’s skin. • The nurse should clean the skin thoroughly and note any breaks in skin integrity. • Disinfectant may be applied to any lesions. • The nurse then applies cotton padding material to prevent direct contact of the casting material with the skin.
- 22. • Extra padding may also be placed over any bony prominences to decrease pressure from the cast and help prevent the development of pressure ulcers. • A stockinette material is then placed over the padding to hold it in place and to provide the skin with protection from the cast edges. • It is important that these materials be applied without wrinkles to prevent areas of pressure and skin breakdown.
- 23. • After the application of the cast, special precautions should be taken until the cast has dried completely. • Drying time will vary dependent upon the type of casting material used. • Plaster of Paris takes the longest to dry, requiring 24–48 hours to completely dry and permit weightbearing. • Plaster will harden in approximately 15 minutes, but it takes much longer for the multiple layers to completely dry. • Synthetic casts require about 30 minutes to dry completely.
- 24. • General Nursing Care Following Cast Application • The most common complication after the application of a cast is neurovascular compromise due to edema and constriction by the cast. • Compartment syndrome can develop.
- 25. • The extremity should be kept elevated above heart level for the first 24–48 hours to decrease the development of edema. • An arm that is casted should be rested in a sling with the fingers elevated above the elbow. • The nurse should carefully perform neurovascular checks on the affected extremity every 30 minutes for the first 4 hours following the application of the cast.
- 26. • Neurovascular checks include checking pulse, sensation, movement, color, and temperature of the affected extremity distal to the cast. • Comparing assessment findings for the affected extremity to the unaffected extremity will help the nurse determine if assessment findings are within normal limits for the patient.
- 27. • Another aspect of the neurovascular check is assessing for the presence of pain. • One example of potential nerve damage that can occur in patients with leg casts is injury to the peroneal nerve that lies laterally on the outer aspect of the calf. • Damage to the peroneal nerve results in foot drop and will cause the patient to be unable to lift the foot when ambulating.
- 28. • To relieve constriction caused by a cast that has become too tight, the cast should be bivalved, or cut in half along both sides of the cast. • Bivalving a cast involves cutting through the cast and the padding underneath. • The cast is then spread apart to relieve constriction. • After the constriction has been relieved, an Ace bandage can be applied to the cast parts to hold the cast intact and maintain alignment of the fracture.
- 29. • Patients who are being discharged home immediately following the application of a cast should be instructed on how to perform neurovascular checks and what indicators require immediate medical attention. • Additional nursing care includes assessing the cast for any drainage, wet spots, or unusual odors. The nurse should circle, date and time any drainage areas observed on the cast and note if the drainage area continues to grow.
- 30. • Skin care is another important aspect of nursing care after the application of a cast. • The skin at the edges of the cast should be routinely inspected for signs of redness and irritation. • The cast edges can be covered in adhesive tape or the stockinette can be pulled back over the edges to prevent skin irritation. • The skin can be cleansed gently with warm water to remove any cast fragments.
- 31. • For patients with a lower extremity cast, ambulation and weight- bearing will begin as the physician prescribes. • It will be important for the patient to maintain muscle strength by performing isometric exercises such as quadriceps setting and gluteal setting. • All unaffected joints should be put through normal range-of-motion exercises.
- 32. • The patient should be encouraged to exercise the toes. • Maintaining upper body strength is also important as the patient will need to be able to use assistive devices such as walkers or crutches. • When weight-bearing is allowed, a cast boot or walking heel will be used to provide protection to the cast.
- 33. • For patients with an arm cast, the nurse should encourage the patient to do finger exercises and shoulder exercises as allowed. • The patient may experience frustration as he or she tries to accommodate to using one arm to perform activities of daily living. • The patient should use a sling whenever ambulating to keep the arm elevated and provide support. • It is important that the sling strap be adjusted correctly to avoid placing too much pressure on the cervical spinal nerves. • The patient should be told to keep the arm elevated when resting to prevent edema.
- 34. • Care of the Patient in a Body or Spica Cast • Body casts are used to immobilize the spine; hip spica casts are used following some hip surgeries and for treatment of some femoral fractures. Shoulder spica casts are used to treat some humeral neck fractures. 1. Assistance for daily hygiene needs. 2. Reduce anxiety ( reassurance) 3. Pain medication 4. turning every 2 hours to promote drying and ensure that pressure is not placed on any one side of the cast for prolonged periods
- 35. 5. Daily assessment on each shift to detect any signs of irritation or pressure of the skin. 6. The perineal area of the cast will have an opening that will allow for daily hygiene care to be administered.
- 36. • Removal of a Cast • The cast will be removed with the use of a cast cutter. • When it is time for the cast to be removed, the nurse should explain the procedure to the patient. • Some patients are anxious about the use of the cast cutter and must be reassured that the cutter will not penetrate the skin. • The padding underneath the cast is cut with scissors and carefully removed.
- 37. • The nurse also must prepare the patient for the appearance of the body part after the cast is removed. • The skin on the body part will appear dry and scaly; it may itch. • The patient should be cautioned not to scratch the skin, as it will be easily irritated. • The skin should be gently washed and lotion applied. The body part will also be stiff and weak due to lack of use. • The patient should gradually resume normal activity. Physical therapy may be prescribed to assist the patient to regain strength and mobility.
- 38. CARE OF THE PATIENT IN TRACTION • Traction is used to provide pull to a body part, while countertraction is applied to pull in the opposite direction. • Is used to treat: 1. a fracture 2. maintain normal alignment of the bone ends. 3. muscle spasms and contractions. 4. deformities.
- 39. • There are three types of traction -skin -skeletal -manual
- 40. • Traction can also be classified as either: -running (straight) -balanced suspension traction.
- 41. • Running traction • the affected body part is allowed to rest on the bed with the traction applied in a straight line. • With running traction, the patient must maintain his or her position in order to maintain the pull of the traction.
- 42. • Balanced suspension traction: • on the other hand, allows the patient to change position in bed while still accurately maintaining the traction pull. • This is achieved by suspending and supporting the affected extremity above the bed with a series of weights and pulleys that maintain the line of pull whenever the patient shifts position
- 43. • PRINCIPLES OF TRACTION • Patient must be placed in correct body alignment in center of bed to maintain line of pull • Traction is maintained continuously, unless the physician prescribes otherwise • Countertraction is maintained continuously • All ropes must move freely on the pulley at all times
- 44. • Rope knots should never touch the pulley • Ropes should be kept clear of bed linens and any other objects • Weights must hang freely at all times • Skeletal traction must never be released
- 45. 1. Skin Traction • Skin traction is applied directly to the patient’s skin through the use of a traction boot, a traction strip, halters, or belts. • Can be either: running traction or balanced suspension traction. • Buck’s extension traction, Russell’s traction, pelvic, and cervical traction. • The amount of weight used in skin traction tends to average 5 to 7 pounds (2.5kg to 3.15)
- 46. • pelvic traction may require more weight (10 to 20 pounds) based upon the patient’s weight. • The amount of weight used is also dependent upon the muscle mass of the patient; more weight is needed to overcome muscle spasms in the larger, stronger muscles.
- 48. • Buck’s extension traction is an example of both skin traction and running traction. • This traction is used to immobilize the lower extremities, usually due to a hip fracture. • Buck’s traction is applied preoperatively to reduce the fracture, maintain alignment, and decrease patient discomfort. • Buck’s traction may also be used to reduce muscle spasms, treat low back pain, and help correct contractures of the hip and knee. • The amount of weight applied for Buck’s traction is usually 3–8 pounds. The patient’s weight and positioning in bed provides countertraction.
- 50. • Russell’s traction is another example of skin traction; it is also an example of balanced suspension traction. • Russell’s traction allows for the knee to be flexed and suspended in a sling. The traction pull extends horizontally along the leg. • This type of traction is most often used to immobilize a fractured tibia
- 51. • contraindications • Impaired circulation • skin irritations • wounds • pressure sores
- 52. • Nurse care • care should be taken to not secure the traction too tightly to the extremity, as this can impair circulation, cause nerve damage, and create pressure sores, especially over the bony prominences. • the nurse should assess carefully for the complication of deep vein thrombosis. - redness -warmth -foot or leg edema. - calf tenderness or pain in the posterior thigh or popliteal area
- 53. 2. Skeletal Traction • the pulling force of the traction is applied directly to a metal pin or wire that has been inserted through the bone. -A Steinmann pin -Kirschner wire
- 54. • The use of skeletal traction allows for a direct pull on the bone fragments to achieve alignment. • Skeletal traction requires that the patient undergo a surgical procedure to insert the pin or wire into the bone (usually into the distal femur or proximal tibia) so that the traction weights can be applied.
- 55. • Skeletal traction is most commonly used for femoral fractures. -cervical spine. -humerus. -tibia. • Weight 15 to 25 pounds
- 56. • Balanced suspension traction is often used with skeletal traction to support the affected extremity. • The Thomas Splint with the Pearson attachment is a form of balanced suspension traction used with lower extremity fractures.
- 58. • potential complication 1. Nonunion 2. skin breakdown. 3. neurovascular status impair 4. Deep vein thrombosis 5. Infection 6. Constipation 7. Urinary tract infection
- 59. CARE OF THE PATIENT WITH AN EXTERNAL FIXATION DEVICE • External fixation devices are metal frame structures that are externally applied to support and stabilize a fracture. 1. open, complicated fracture with soft tissue injury, 2. traction or a cast is contraindicated. • The external device allows the wound to be treated while the fracture is reduced and held in alignment. It also promotes earlier mobility.
- 60. • The external fixation device is attached to the bone through the use of a series of pins that are screwed into the bone. • Femur • Tibia • Humerus • Forearm • pelvis
