22.14: Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.

Nursing Assessment

Vital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.

Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and sensory and motor function of the affected extremity. Compare these observations with those of the other extremity and record them initially every 15 minutes, then at longer intervals if the condition is stable.

Ankle-Brachial Index (ABI): Measure ABI at least once every 8 hours for the first 24 hours and then daily until discharge unless contraindicated.

Fluid balance monitoring: Continuously monitor fluid balance, including urine output and central venous pressure, to recognize and treat fluid imbalance promptly.

Incision site inspection: Inspect the surgical site for redness, swelling, or discharge.

Nursing Diagnosis

Based on these assessments, the nurse formulates nursing diagnoses such as:

• Acute pain related to surgical incisions, as evidenced by the patient’s verbal reports of pain and observed facial grimacing.
• Impaired physical mobility related to decreased blood flow to the extremities and surgical site discomfort, as evidenced by observed limited range of motion in the affected areas and the need for assistance with ambulation and daily activities.
• Anxiety related to fear of complications and concern about recovery, as evidenced by the patient’s verbal expressions of worry, restlessness, and increased muscle tension.

Next, the nurse collaborates with the patient to set goals, such as reducing pain, improving mobility, reducing anxiety, and implementing interventions to achieve these goals.

Nursing interventions

Maintaining circulation:

• Regularly check and document the pulses of the affected and unaffected extremities, using Doppler evaluation for accuracy.
• Conduct Arterial Brachial Index (ABI) assessments regularly and notify the surgeon immediately if a previously present pulse disappears, indicating possible thrombotic occlusion of the graft.
• Avoid leg crossing and prolonged extremity dependency to prevent thrombosis.
• Elevate the extremities and encourage exercises to reduce edema. Use graduated compression or anti-embolism stockings cautiously to avoid compressing distal vessel bypass grafts or inducing pressure injuries.

Monitoring for potential complications:

• Monitor for signs of bleeding, which can result from heparin given during surgery or an anastomotic leak. Check for hematoma formation and review the operative report for heparin reversal with protamine sulfate.
• Severe edema, pain, and decreased sensation in toes or fingers can indicate compartment syndrome. Elevate the extremities and encourage exercises to reduce edema.
• Monitor urine output and central venous pressure to detect fluid imbalances. Maintain adequate circulating blood volume.

Pain management:

• Administer prescribed analgesics and provide non-pharmacological pain relief methods such as positioning, ice packs, and relaxation techniques.
• Ensure proper incision site care, including regular dressing changes and monitoring for signs of dehiscence and infection.
• Administer prophylactic antibiotics as ordered. Educate the patient on the signs of infection to report.
• Assist the patient with early ambulation and provide support as needed. Encourage leg exercises to promote circulation and prevent venous stasis.

Activity and mobility:

• Encourage a gradual increase in physical activity as tolerated, with walking particularly beneficial for improving circulation.
• Patients should avoid prolonged sitting or standing and be advised to move regularly to promote blood flow. Providing proper position to the patient, such as keeping the affected extremity elevated when sitting or lying down, is recommended to reduce swelling.

Follow-up care

Provide emotional support and address any anxiety or concerns the patient may have about their recovery and future mobility. Patients must understand the importance of keeping follow-up appointments with healthcare providers to monitor recovery and manage peripheral artery disease (PAD). Educating patients on recognizing signs of infection, such as redness and swelling, and avoiding prolonged sitting or standing is essential for preventing complications. Discussing non-pharmacological pain management techniques, like elevating the affected extremities and using ice packs, helps patients manage pain effectively at home.
