Complications

Flexion contractures Flexion contractures are more likely with the hip or knee joint following amputation due to improper positioning. NURSING ACTIONS ●Prevention includes range-of-motion (ROM) exercises and proper positioning immediately after surgery. ●To prevent hip or knee flexion contracture, some providers do not advocate elevating the stump on a pillow. Other providers allow elevation for the first 24 to 48 hr to reduce swelling and discomfort. ●Have the client lie prone for 20 to 30 min several times a day to help prevent hip flexion contractions. ●Have a physical therapist teach the client some exercises that will prevent contractions. CLIENT EDUCATION: Stand using good posture with the residual limb in extension. This also will aid in balance.

Patient-Centered Care Conti...

Management of traumatic imputation ●Implement a medical emergency system (EMS). ●Apply direct pressure using gauze (if available) or clean cloth to prevent life-threatening hemorrhage. ●Elevate the extremity above the heart to decrease blood loss. ●Wrap the severed extremity in dry sterile gauze (if available) or in a clean cloth, and place in a sealed plastic bag in ice water (one part ice and three parts), and send with the client. Pain ●Monitor and treat pain. ●Differentiate between phantom limb and incisional pain. Incisional pain is treated with analgesics or PCA pump. Phantom limb pain ●The sensation of pain in the location of the extremity following the amputation ●Related to severed nerve pathways and is a frequent complication in clients who experienced chronic limb pain before the amputation ●Can be expected immediately after surgery, for up to several weeks, or indefinitely. ●Occurs less frequently following traumatic amputation. ●Often described as deep and burning, tingling, cramping, shooting, or aching. ●Treated much differently from incisional pain ●IV fusion of ketamine can reduce or eliminate phantom pain. ◯Administration of calcitonin during the first week after having an amputation can decrease phantom limb pain. ◯Administering beta-blocker, such as propranolol, can relieve the continual dull, burning sensation associated with phantom pain. ◯Administering antiepileptics (gabapentin or pregabalin) can relieve sharp, stabbing, and burning phantom limb pain. ◯Some clients have relief from antispasmodics, such as baclofen, and antidepressant medications. ◯Recognize the pain is real and manage it accordingly. ◯Alternative treatment for phantom limb pain can include nonpharmacological methods (massage, heat, transcutaneous electrical nerve stimulation [TENS], ultrasound therapy, biofeedback, acupuncture, relaxation therapy). ◯A stump stocking with an electromagnetic shield blocks external electromagnetic impulses from outside sources, which are thought to cause phantom pain. ◯Virtual reality goggles help visualize the limb as a whole. ◯Reinforce with the client how to push the residual limb down toward the bed while supported on a soft pillow. This helps reduce phantom limb pain and prepare the limb for a prosthesis. Client perception and feelings regarding amputation ●Allow for the client and family to grieve for the loss of the body part and change in body image. ●Feelings can include depression, anger, withdrawal, and grief. ●Monitor the psychosocial well-being of the client. Check for feelings of altered self-concept and self-esteem, and willingness and motivation for rehabilitation. ●Facilitate a supportive environment for the client and family so grief can be processed. Refer the client to religious/spiritual adviser, social worker, or counselor. ●Rehabilitation should include adaptation to a new body image and integration of prosthetic and adaptive devices into self-image. Residual limb preparation and prosthesis fitting Residual limb must be shaped and shrunk in preparation for prosthetic training. SHRINKAGE INTERVENTIONS ●Wrap the residual limb up to three times daily, using elastic bandages (figure-eight wrap) to prevent restriction of blood flow and decrease edema. ●Use a residual limb shrinker sock (easier for the client to apply). ●Use an air splint (plastic inflatable device) inflated to protect and shape the residual limb and for easy access to inspect the wound. CLIENT EDUCATION ●Amputation can alter sense of balance due to a disruption in the body's center of gravity. ●Use a mirror to monitor the stump daily for redness, or abrasions. ●Wash the stump daily with bacterial soap and completely rinse and dry it. ●Replace the stump sock daily. ●Apply the prosthesis immediately when getting out of bed to reduce swelling. ●Perform exercises to increase strength. ●Replace shoes frequently to prevent falls, ●Clean the prosthesis socket daily with a damp cloth. Dry the prosthesis socket thoroughly. ●Consult with prosthetic orthosis for prosthetic adjustments and yearly checks THERAPEUTIC PROCEDURES Closed amputation: This is the most common technique used. A skin flap is sutured over the end of the residual limb, closing the site. A compression dressing is applied after surgery to decrease swelling and prevent infection. Open amputation: This technique is used when an active infection is present. A skin flap is not sutured over the end of the residual limb, allowing for drainage of infection. The skin flap is closed at a later date. INTRAPROFESSIONAL CARE Intensive efforts by the interprofessional team are necessary to facilitate successful rehabilitation. ●A certified prosthetic orthotist will fit client with prosthesis after the wound is healed and the residual limb has shrunk. ●A physical therapist will train the client in the application and care of the prosthesis and mobility aids. ●An occupational therapist can assist the client with performing ADLs. ●A psychologist can be needed to help with adjustment to loss of the extremity. ●A social worker will assist the client who has financial issues and can refer the client to resources and a support group or organization for people who have had amputations

Patient-Centered Care

NURSING CARE Preoperative ●Involve the client in decision to amputate, and explain what to expect postoperatively. ●Expect clients to experience stages of denial and anger. ●Reinforce teaching about phantom limb pain. ●Reinforce teaching about muscle strengthening exercises. Postoperative ●Prevent postoperative complications (hypovolemia, pain, edema, infection). ●Elevate for the first 24 to 48 hr (lower extremities are usually not elevated for longer than 24 hr due to the risk of hip contractures). ●Monitor dressings and surgical site for bleeding. Monitor vital signs frequently. ●Monitor tissue perfusion of end of residual limb. ◯Palpate residual limb for warmth. Heat can indicate infection. ◯Compare pulse most proximal to incision with pulse in other extremity. ●Monitor for manifestations of infection and non-healing of incision. Infection can lead to osteomyelitis. ◯Elevate the stump, if ordered, to increase circulation and decrease pain and swelling. ◯Administer antibiotics and change dressings as prescribed if open amputation was performed. ◯Record characteristics of drainage (amount, color, and odor). ◯Keep a surgical tourniquet at the beside. ◯Change positions frequently.

Data Collection

RISK FACTORS ●Traumatic injury: motor vehicle crashes, industrial equipment, war-related injuries ●Thermal injury: frostbite, electrocution, burns ●Malignancy CHRONIC DISEASE PROCESSES ●Older adult clients have a higher risk of peripheral vascular disease and diabetes mellitus resulting in decreased tissue perfusion and peripheral neuropathy. Both conditions place older adult clients at risk for lower extremity amputation ●Peripheral vascular disease resulting in ischemia/gangrene ●Diabetes mellitus resulting in peripheral neuropathy and peripheral vascular disease ●Infection (osteomyelitis) ●Congenital defects EXPECTED FINDINGS Decreased tissue perfusion ●Clients might report pain ●History of injury or disease process precipitating amputation ●Altered peripheral pulses compared to the client's expected skin tone (can use a Doppler if needed) ●Differences in temperature of extremities (note the level of leg at which temperature becomes cool) ●Altered color of extremities (pallor, cyanosis, or gangrenous skin) ●Presence of infection and open wounds ●Lack of sensation in the affected extremity NURSING ACTIONS Neurological checks ●Monitor capillary refill by comparing the extremities. In older adult clients, capillary refill can be difficult to monitor due to thickened and opaque nails. ●Observe for edema, necrosis, and lack of hair distribution of the extremity due to inadequate peripheral circulation. ●Monitor peripheral pulses bilateral DIAGNOSTIC PROCEDURES To determine blood flow at various levels of an extremity Angiography: Allows visualization of peripheral vasculature and areas of impaired circulation. Doppler laser and ultrasonography studies: Measures speed of blood flow in an extremity. Transcutaneous oxygen pressure (TcPO2): Measures oxygen pressures in an extremity to indicate blood flow in the extremity, which is reliable indicator for healing. Ankle-brachial index: Measures difference between ankle and branchial systolic pressures.

Upper and Lower

UPPER EXTREMITY AMPUTATIONS ●Upper extremity amputations include above- and below-the-elbow amputations, wrist, and shoulder disarticulations, and finger amputations. ●Traumatic amputation caused by accidents, war, or injury is the primary cause of upper extremity amputations. ●Other causes include vasospastic disease, malignancy, and infection of extremity. LOWER EXTREMITY AMPUTATIONS ●Lower extremity amputations include above-and below-the-knee amputations, hip and knee disarticulations, Syme's amputation (removal of foot with ankle saved), and mid-foot and toe amputations. ●Peripheral vascular disease is the cause of most lower extremity amputations. ●Every effort is made to save as much of the extremity as possible. Even loss of the big toe can significantly affect balance, gait, and push-off ability during ambulation. Salvage of the knee with a below-the-knee amputation also improves function vs. an above-the-knee amputation.

Health Promotion and Disease Preventions

●Clients who have diabetes mellitus should monitor blood glucose and maintain it within the expected reference range. ●Use safety measures when working with heavy machinery or in areas where there is a risk of electrocution or burns. ●Encourage clients to quit or not start smoking, maintain a healthy weight, and exercise regularly. ●Tell clients to maintain good foot care and to seek early medical attention for non-healing wounds
