Pulmonary embolism (PE) is a critical condition characterized by the obstruction of one or more pulmonary arteries by a thrombus, most commonly originating from deep vein thrombosis (DVT) in the lower extremities. This blockage disrupts pulmonary blood flow, leading to decreased oxygenation, impaired gas exchange, and potentially life-threatening complications. Prompt diagnosis and effective nursing care are paramount in improving patient outcomes and reducing mortality associated with pulmonary embolism.
Nurses play a vital role in the multidisciplinary management of pulmonary embolism, from initial assessment and stabilization to implementing life-saving interventions and patient education. This comprehensive guide focuses on nursing diagnoses relevant to pulmonary embolism and outlines a detailed care plan to guide nursing interventions, optimize patient care, and improve recovery.
In-Depth Nursing Assessment for Pulmonary Embolism
A thorough nursing assessment is the cornerstone of effective care for patients with suspected or confirmed pulmonary embolism. It involves gathering both subjective and objective data to identify risk factors, clinical manifestations, and guide the selection of appropriate nursing diagnoses and interventions.
Detailed Review of Health History
1. Comprehensive Symptom Evaluation: Elicit a detailed account of the patient’s presenting symptoms, as these can vary widely depending on the size and location of the embolus. Key symptoms to document include:
- Dyspnea: Sudden onset of shortness of breath, often unexplained and disproportionate to exertion.
- Tachypnea: Rapid breathing, often exceeding 20 breaths per minute, as the body attempts to compensate for reduced oxygenation.
- Chest Pain: Typically pleuritic in nature, worsening with deep inspiration or coughing; may be described as sharp, stabbing, or aching.
- Cough: May be present, sometimes productive of blood-tinged sputum (hemoptysis).
- Hemoptysis: Coughing up blood, indicating pulmonary tissue injury or infarction.
- Syncope: Fainting or lightheadedness, potentially due to decreased cardiac output and cerebral hypoperfusion.
- Anxiety and Restlessness: Common responses to dyspnea and hypoxia.
- Lower Extremity Pain or Swelling: Suggestive of DVT, the primary source of most pulmonary emboli.
2. Thorough Risk Factor Identification: Assess for predisposing factors that increase the patient’s susceptibility to venous thromboembolism (VTE), including DVT and PE:
- Immobility: Prolonged bed rest, paralysis, or prolonged travel significantly increase risk.
- Previous VTE: A history of DVT or PE is a strong predictor of recurrence.
- Active Cancer: Malignancy and its treatment (chemotherapy, radiation) are major risk factors.
- Recent Surgery: Especially orthopedic or major abdominal surgery, increases hypercoagulability and immobility.
- Obesity: Excess weight contributes to venous stasis and hypercoagulability.
- Oral Contraceptives & Hormone Replacement Therapy: Estrogen-containing medications increase clotting risk.
- Pregnancy & Postpartum Period: Pregnancy-related hormonal changes and venous compression increase risk.
- Smoking: Damages blood vessels and promotes hypercoagulability.
- Inherited Clotting Disorders (Thrombophilia): Genetic predispositions to excessive clotting.
- Varicose Veins: Impaired venous return and stasis contribute to clot formation.
- Trauma: Especially fractures of the pelvis, hip, or femur, release fat emboli and promote hypercoagulability.
3. Family History of VTE: Inquire about any family history of pulmonary embolism or deep vein thrombosis, as genetic factors can increase individual risk.
4. Past and Present Medical History Review: Obtain a comprehensive medical history, including:
- Cardiovascular Disease: Pre-existing heart conditions can exacerbate the hemodynamic effects of PE.
- Chronic Lung Disease: Conditions like COPD or asthma may complicate the respiratory symptoms of PE.
- Surgical History: Recent surgeries, especially those involving prolonged immobilization or major trauma.
- Medication History: Document all current medications, including anticoagulants, hormones, and over-the-counter drugs.
5. Pulmonary Embolism Rule-out Criteria (PERC) Application: In emergency settings, the PERC rule can help identify low-risk patients who may not require immediate extensive testing for PE. The eight PERC criteria are:
- Age < 50 years
- Heart rate < 100 bpm
- Oxygen saturation ≥ 95% on room air
- No hemoptysis
- No hormone replacement therapy or oral contraceptives
- No prior VTE
- No unilateral leg edema
- No surgery or trauma requiring hospitalization within the past 4 weeks
Patients negative for all eight PERC criteria have a very low probability of PE and may avoid further diagnostic testing.
Detailed Physical Assessment
1. Rapid Assessment of Critical Symptoms: Prioritize assessment based on symptom severity. Unexplained dyspnea, chest pain, and syncope are red flags requiring immediate attention and evaluation for pulmonary embolism.
2. Vital Signs Monitoring: Closely monitor vital signs for indicators of hemodynamic instability. Abnormal findings may include:
- Tachycardia: Heart rate > 100 bpm, a compensatory mechanism for decreased cardiac output and oxygenation.
- Tachypnea: Respiratory rate > 20 breaths per minute, reflecting the body’s attempt to improve oxygen intake.
- Hypotension: Systolic blood pressure < 90 mmHg, indicating significant hemodynamic compromise, especially in massive PE.
- Hypoxia: Oxygen saturation < 90% on room air, reflecting impaired gas exchange.
- Fever: May be present, especially in cases of pulmonary infarction.
3. Systematic Physical Examination: Perform a head-to-toe assessment, focusing on systems most affected by PE:
- Neck: Assess for jugular vein distention (JVD), indicating right ventricular dysfunction and increased central venous pressure.
- Central Nervous System (CNS): Evaluate level of consciousness, orientation, and presence of confusion or restlessness, which may signify hypoxia.
- Cardiovascular System:
- Auscultate heart sounds for murmurs, gallops (S3 or S4), and accentuated pulmonic component of the second heart sound (P2), which can indicate pulmonary hypertension.
- Assess for chest pain, noting location, character, and radiation.
- Palpate peripheral pulses for rate, rhythm, and quality, noting any signs of decreased perfusion.
- Respiratory System:
- Observe respiratory rate, depth, and effort, noting any use of accessory muscles.
- Auscultate breath sounds for adventitious sounds such as wheezes, crackles, or pleural friction rub. Note any areas of decreased or absent breath sounds.
- Assess for cough and sputum production.
- Evaluate for signs of cyanosis (bluish discoloration of skin and mucous membranes), indicating hypoxemia.
- Circulatory System:
- Inspect skin color and temperature, noting pallor, cyanosis, or coolness, especially in extremities.
- Palpate for peripheral edema, particularly in the lower extremities, which may suggest DVT.
- Assess for calf tenderness, warmth, or palpable cords, suggestive of DVT.
- Musculoskeletal System: Evaluate for muscle weakness, fatigue, or syncope.
- Integumentary System: Assess skin for color, temperature, moisture, and presence of diaphoresis (excessive sweating).
Diagnostic Procedures and Interpretation
It’s crucial to remember that chest pain and dyspnea are non-specific symptoms that can mimic other conditions such as myocardial infarction, pneumonia, or pneumothorax. Diagnostic testing is essential to confirm or exclude pulmonary embolism.
1. Electrocardiogram (ECG): While ECG findings are often non-specific in PE, certain abnormalities may raise suspicion or help rule out cardiac etiologies. Common ECG changes include:
- Sinus Tachycardia: The most frequent finding.
- Non-specific ST-segment and T-wave changes: Suggestive of myocardial ischemia or strain.
- S1Q3T3 Pattern: Classic but infrequent finding, indicating right ventricular strain (deep S wave in lead I, Q wave in lead III, and inverted T wave in lead III).
- Right Ventricular Strain: Evidenced by T-wave inversions in anterior precordial leads (V1-V4).
- New Incomplete Right Bundle Branch Block: Suggestive of right ventricular overload.
2. D-dimer Blood Test: This highly sensitive test measures fibrin degradation products, which are elevated when clots are being broken down.
- Elevated D-dimer: Suggests the presence of clot formation and breakdown, but is not specific for PE (can be elevated in other conditions like infection, malignancy, pregnancy). A negative D-dimer in a low-risk patient effectively rules out PE.
- Normal D-dimer: Strongly suggests absence of acute PE in low-risk patients.
3. Other Blood Tests:
- Complete Blood Count (CBC) with Differential: May reveal underlying infection or anemia, but is not diagnostic for PE.
- Coagulation Studies (PT/INR, PTT): Baseline coagulation tests are important before initiating anticoagulation therapy. PTT is used to monitor unfractionated heparin therapy.
4. Chest X-ray: Often normal in PE, but essential to rule out other pulmonary conditions such as pneumonia or pneumothorax. May show subtle findings like Westermark’s sign (focal oligemia) or Hampton’s hump (wedge-shaped pleural infiltrate), but these are infrequent and non-specific.
5. Computed Tomographic Pulmonary Angiography (CTPA): The gold standard imaging modality for diagnosing PE.
- High Sensitivity and Specificity: Effectively visualizes pulmonary arteries and detects clots with high accuracy.
- Rapid and Widely Available: CTPA is readily accessible in most hospitals and can be performed quickly.
- Contrast Dye: Requires intravenous contrast dye, which is contraindicated in patients with severe renal insufficiency or allergy to iodinated contrast. Pre-hydration and alternative imaging modalities may be necessary in these patients.
6. Ventilation/Perfusion (V/Q) Scan: An alternative imaging technique, particularly useful when CTPA is contraindicated (e.g., pregnancy, contrast allergy, renal insufficiency).
- Assesses Airflow and Blood Flow: Compares ventilation (air reaching alveoli) to perfusion (blood flow to lungs).
- Mismatch Pattern: A “mismatch” (normal ventilation with reduced perfusion) suggests PE.
- Less Sensitive than CTPA: V/Q scans are less sensitive and specific than CTPA for detecting small peripheral emboli.
- Indeterminate Results: V/Q scans can be indeterminate, requiring further investigation.
7. Echocardiography: Particularly useful in patients with hemodynamically unstable PE or suspected right ventricular dysfunction.
- Evaluates Right Ventricular Function: May show right ventricular dilation, hypokinesis, and increased pulmonary artery pressure, indicative of right heart strain due to PE.
- Identifies Proximal Emboli: In rare cases, may directly visualize large emboli in the right atrium or pulmonary arteries.
8. Venous Doppler Ultrasound: Used to detect DVT in the lower extremities, the most common source of PE.
- Non-invasive and Readily Available: Useful in patients with suspected DVT as the source of PE.
- Positive DVT: Confirms a source for PE and may guide treatment decisions.
- Negative DVT: Does not rule out PE, as the embolus may have already traveled to the lungs.
Prioritized Nursing Diagnoses for Pulmonary Embolism
Based on the assessment findings, several nursing diagnoses are commonly relevant in patients with pulmonary embolism. Prioritization of these diagnoses depends on the individual patient’s clinical presentation and severity of illness. Key nursing diagnoses include:
- Impaired Gas Exchange related to ventilation-perfusion mismatch secondary to pulmonary embolism, as evidenced by hypoxemia, dyspnea, and abnormal arterial blood gases (ABGs).
- Acute Pain related to pulmonary tissue hypoxia and inflammatory processes secondary to pulmonary embolism, as evidenced by chest pain, dyspnea, and guarding behavior.
- Anxiety related to fear of death, severity of illness, and unfamiliar hospital environment secondary to pulmonary embolism, as evidenced by restlessness, tachycardia, and expressed concerns.
- Decreased Cardiac Output related to increased pulmonary vascular resistance and right ventricular dysfunction secondary to pulmonary embolism, as evidenced by hypotension, tachycardia, and decreased peripheral perfusion.
- Ineffective Breathing Pattern related to pain and hypoxemia secondary to pulmonary embolism, as evidenced by tachypnea, dyspnea, and use of accessory muscles.
