Coronary Artery Bypass Graft (CABG) surgery is a critical intervention for patients with severe coronary artery disease (CAD), aiming to restore blood flow to the heart muscle. While CABG addresses the physical blockage, comprehensive post-operative care is essential for patient recovery and long-term well-being. This care heavily relies on meticulous nursing care plans that address potential complications and support the patient through their recovery journey.
Effective nursing care plans are structured around accurate nursing diagnoses, which are clinical judgments about individual, family, or community responses to actual and potential health problems or life processes. In the context of post-CABG care, these diagnoses guide interventions aimed at optimizing patient outcomes. This article will delve into common nursing diagnoses relevant to patients undergoing CABG, providing a framework for developing effective care plans.
Common Post-CABG Nursing Diagnoses and Care Plans
Following CABG surgery, patients are susceptible to a range of physiological and psychological challenges. Nurses play a pivotal role in identifying these challenges through thorough assessment and formulating appropriate nursing diagnoses. Here are some of the most pertinent nursing diagnoses in the post-CABG setting, along with corresponding care plan components:
1. Acute Pain
Post-operative pain is an expected outcome of CABG surgery, stemming from the surgical incision sites (chest and potentially leg, if a saphenous vein graft was used), chest tube insertion, and manipulation of tissues during the procedure. Inadequate pain management can hinder recovery, impede mobility, and contribute to complications.
Nursing Diagnosis: Acute Pain related to surgical trauma and invasive procedures as evidenced by patient report of pain, guarding behavior, changes in vital signs, and restlessness.
Expected Outcomes:
- Patient will report pain is managed to a tolerable level (e.g., rating ≤ 3 on a 0-10 scale) within 24-48 hours post-operatively.
- Patient will demonstrate effective pain management strategies, including medication administration and non-pharmacological techniques.
- Patient will participate in post-operative activities (e.g., coughing, deep breathing, ambulation) without significant pain exacerbation.
Nursing Interventions:
- Assess Pain Characteristics: Regularly assess pain using a standardized pain scale (numerical rating scale, visual analog scale) and evaluate pain location, quality, intensity, onset, duration, and aggravating/relieving factors. Differentiate between incisional pain, chest tube pain, and angina-like pain.
- Pharmacological Pain Management: Administer analgesics as prescribed, including opioids (e.g., morphine, fentanyl) in the immediate post-operative period and transition to non-opioid analgesics (e.g., acetaminophen, NSAIDs) as pain subsides. Utilize patient-controlled analgesia (PCA) if appropriate.
- Non-Pharmacological Pain Management: Implement non-pharmacological measures such as:
- Positioning: Assist the patient to find a comfortable position that minimizes incisional strain. Encourage frequent position changes.
- Splinting: Instruct the patient to splint the chest incision with a pillow during coughing and deep breathing exercises.
- Relaxation Techniques: Teach and encourage relaxation techniques such as deep breathing exercises, guided imagery, and meditation.
- Massage: Gentle back or shoulder massage may help reduce muscle tension and pain.
- Heat/Cold Therapy: Apply heat or cold packs to incision sites as prescribed or per protocol to reduce pain and inflammation.
- Evaluate and Document Pain Relief: Continuously evaluate the effectiveness of pain management interventions and document pain levels, medication administration, and patient response. Adjust pain management strategies as needed in collaboration with the healthcare provider.
- Patient Education: Educate the patient and family about the importance of pain management, the pain scale, available pain relief options, and how to report pain effectively.

2. Risk for Infection
CABG surgery, like all surgical procedures, carries a risk of infection. Surgical site infections (SSIs), mediastinitis (infection of the mediastinum, the space behind the sternum), pneumonia, and urinary tract infections are potential post-operative complications that can significantly impact recovery.
Nursing Diagnosis: Risk for Infection related to surgical incision, invasive lines (IVs, chest tubes, urinary catheter), and suppressed immune response post-surgery.
Expected Outcomes:
- Patient will remain free from signs and symptoms of infection throughout the hospital stay.
- Patient will demonstrate understanding of infection prevention measures (e.g., hand hygiene, incision care).
- Patient will maintain normal temperature, white blood cell count, and wound healing progression.
Nursing Interventions:
- Aseptic Technique: Maintain strict aseptic technique during dressing changes, IV line insertion and care, urinary catheter care, and chest tube management.
- Incision Site Care: Assess surgical incision sites daily for signs of infection (redness, warmth, swelling, drainage, pain). Cleanse incision sites as per protocol, typically with antiseptic solutions, and apply sterile dressings.
- Chest Tube Care: Maintain a closed chest drainage system. Monitor chest tube insertion sites for infection. Ensure proper chest tube function and drainage.
- Urinary Catheter Care: Provide meticulous perineal care and maintain a closed urinary drainage system. Remove the urinary catheter as soon as clinically appropriate to reduce UTI risk.
- Respiratory Hygiene: Encourage deep breathing and coughing exercises to prevent pneumonia. Assist with incentive spirometry. Promote early ambulation to improve lung expansion.
- Hand Hygiene: Emphasize hand hygiene for healthcare providers, patients, and visitors. Provide hand sanitizer readily available.
- Monitor Vital Signs and Labs: Monitor temperature, heart rate, respiratory rate, and white blood cell count regularly for early detection of infection.
- Antibiotic Administration: Administer prophylactic antibiotics as prescribed and monitor for therapeutic effectiveness and adverse effects.
- Patient Education: Educate the patient and family about signs and symptoms of infection, importance of hand hygiene, incision care at home, and when to seek medical attention for potential infection.

3. Decreased Cardiac Output
CABG surgery aims to improve cardiac output, but in the immediate post-operative period, patients may experience decreased cardiac output due to various factors including myocardial stunning, fluid shifts, arrhythmias, and potential graft failure.
Nursing Diagnosis: Decreased Cardiac Output related to altered contractility, changes in heart rate and rhythm, and fluid volume imbalance post-CABG surgery as evidenced by changes in blood pressure, heart rate, EKG changes, decreased urine output, and signs of decreased tissue perfusion.
Expected Outcomes:
- Patient will maintain adequate cardiac output as evidenced by stable vital signs, palpable peripheral pulses, adequate urine output (≥ 30 mL/hr), and absence of signs of decreased tissue perfusion.
- Patient will demonstrate hemodynamic stability within patient-specific parameters.
- Patient will tolerate activity without significant changes in hemodynamic status.
Nursing Interventions:
- Hemodynamic Monitoring: Continuously monitor vital signs (heart rate, blood pressure, respiratory rate, oxygen saturation). Closely monitor cardiac rhythm via ECG. Invasive hemodynamic monitoring (arterial line, central venous pressure monitoring) may be utilized in the immediate post-operative period.
- Fluid Balance Management: Monitor fluid intake and output meticulously. Administer intravenous fluids as prescribed to maintain adequate preload while avoiding fluid overload. Monitor for signs of fluid overload (edema, crackles in lungs, jugular vein distention).
- Medication Administration: Administer medications as prescribed to support cardiac output, such as:
- Inotropes: (e.g., dobutamine, milrinone) to enhance myocardial contractility.
- Vasopressors: (e.g., norepinephrine, dopamine) to maintain blood pressure.
- Vasodilators: (e.g., nitroglycerin, nitroprusside) to reduce afterload and improve coronary artery blood flow.
- Antiarrhythmics: (e.g., amiodarone, beta-blockers) to manage arrhythmias.
- Assess for Signs of Decreased Cardiac Output: Regularly assess for signs of decreased cardiac output and tissue perfusion, including:
- Hypotension or Hypertension: Monitor blood pressure trends.
- Tachycardia or Bradycardia: Assess heart rate and rhythm.
- Decreased Urine Output: Monitor hourly urine output.
- Peripheral Edema: Assess for edema in extremities.
- Cool, Clammy Skin: Evaluate skin temperature and moisture.
- Changes in Mental Status: Assess level of consciousness and orientation.
- Weak Peripheral Pulses: Palpate peripheral pulses (radial, dorsalis pedis, posterior tibial).
- Positioning: Maintain the patient in a semi-Fowler’s or high-Fowler’s position as tolerated to promote venous return and lung expansion.
- Monitor Electrolyte Balance: Monitor serum electrolyte levels, particularly potassium and magnesium, and replace as needed to optimize cardiac function.

4. Ineffective Airway Clearance
Post-CABG patients are at risk for ineffective airway clearance due to pain, anesthesia effects, and reduced mobility, which can lead to atelectasis (collapsed lung) and pneumonia.
Nursing Diagnosis: Ineffective Airway Clearance related to pain, effects of anesthesia, decreased mobility, and increased secretions as evidenced by abnormal breath sounds, ineffective cough, dyspnea, and decreased oxygen saturation.
Expected Outcomes:
- Patient will maintain a patent airway and effective breathing pattern.
- Patient will demonstrate effective coughing techniques and clear lung sounds.
- Patient will maintain oxygen saturation within normal limits (e.g., ≥ 95% on room air or baseline).
Nursing Interventions:
- Respiratory Assessment: Assess respiratory rate, rhythm, depth, and effort. Auscultate breath sounds for adventitious sounds (crackles, wheezes). Monitor oxygen saturation continuously via pulse oximetry.
- Coughing and Deep Breathing Exercises: Encourage hourly coughing and deep breathing exercises while splinting the chest incision. Instruct on proper coughing technique to mobilize secretions.
- Incentive Spirometry: Instruct and assist the patient with incentive spirometry exercises to promote lung expansion and prevent atelectasis. Encourage use every 1-2 hours while awake.
- Positioning: Elevate the head of the bed to a semi-Fowler’s or high-Fowler’s position to promote lung expansion and drainage of secretions.
- Suctioning: If the patient is unable to clear secretions effectively, perform nasotracheal or oropharyngeal suctioning as needed, using sterile technique.
- Humidification: Provide humidified oxygen if supplemental oxygen is required to help liquefy secretions and prevent mucosal drying.
- Early Ambulation: Promote early ambulation as tolerated to improve lung expansion and mobilize secretions.
- Pain Management: Ensure adequate pain management to facilitate effective coughing and deep breathing.
- Monitor Sputum: Assess sputum for color, consistency, and amount. Report any changes suggestive of infection.
