Introduction
Hemoptysis, the expectoration of blood from the respiratory tract, can be alarming for both patients and clinicians. As a junior doctor in the Accident & Emergency (A&E) department, you'll encounter this symptom, which ranges from mild to life-threatening. This guide will help you navigate the critical aspects of history taking, examination, investigation, and management of hemoptysis in the A&E setting.
History Taking: The Key Questions
Onset and Duration:
When did the hemoptysis start?
Is it acute or chronic?
Has there been any previous episode? Volume and Frequency:
How much blood is being coughed up? (Quantify if possible, e.g., teaspoons, cups)
How often does it occur? Character of the Blood:
Is the blood fresh (bright red) or old (dark, clotted)?
Is it mixed with sputum? Associated Symptoms:
Any recent upper respiratory tract infection or cold symptoms?
Presence of fever, night sweats, or weight loss?
Any chest pain, dyspnea, or wheezing?
Symptoms of bleeding from other sites (e.g., nosebleeds, gum bleeding)? Medical and Surgical History:
Any history of lung disease (e.g., COPD, TB, bronchiectasis)?
History of cardiovascular diseases?
Any known bleeding disorders?
Previous surgeries, especially thoracic or cardiovascular? Medications and Allergies:
Use of anticoagulants (e.g., warfarin, DOACs)?
Use of antiplatelets (e.g., aspirin, clopidogrel)?
Any recent changes in medication? Social and Occupational History:
Smoking history (pack-years)?
Occupational exposure to respiratory irritants or toxins?
Travel history (particularly to TB-endemic areas)? Family History:
Any family history of lung disease, bleeding disorders, or malignancies?
Examination: What to Look For
General Appearance:
Look for signs of distress, pallor, or cyanosis.
Assess vital signs: temperature, pulse, blood pressure, respiratory rate, and oxygen saturation. Respiratory Examination:
Inspect for signs of respiratory distress, such as accessory muscle use or intercostal retractions.
Palpate for tenderness or masses.
Percuss to identify areas of dullness (suggestive of consolidation or pleural effusion).
Auscultate for abnormal breath sounds (e.g., crackles, wheezes, bronchial breath sounds). Cardiovascular Examination:
Assess for signs of heart failure (e.g., raised jugular venous pressure, peripheral edema).
Listen for any murmurs or abnormal heart sounds. Other Relevant Examinations:
Inspect the skin and mucous membranes for petechiae, bruising, or other signs of bleeding disorders.
Perform a thorough ENT examination to rule out sources of upper airway bleeding.
Investigations: Finding the Cause
Laboratory Tests:
Complete blood count (CBC) to check for anemia or thrombocytopenia.
Coagulation profile (PT, aPTT, INR) to assess bleeding tendencies.
Renal function tests.
Liver function tests, especially if there's a history of liver disease or alcoholism.
Sputum culture and sensitivity, including acid-fast bacilli (AFB) if TB is suspected.
Blood cultures if there is a suspicion of sepsis. Imaging:
Chest X-ray: First-line imaging to identify masses, infiltrates, or cavitations.
CT Thorax: More sensitive than a chest X-ray, useful for detecting bronchiectasis, malignancy, or vascular abnormalities.
Bronchoscopy: Considered if initial imaging is inconclusive and there is ongoing significant hemoptysis.
Other Tests:
ECG to assess for any cardiac cause if relevant.
Echocardiogram if there is a suspicion of cardiac etiology (e.g., mitral stenosis).
Management: The Approach in A&E
Management of hemoptysis depends on the severity and underlying cause:
Initial Stabilization:
Ensure airway patency and adequate oxygenation. Administer supplemental oxygen if needed.
Establish IV access and initiate resuscitation if the patient is unstable.
Consider positioning the patient to minimize aspiration risk (e.g., lateral decubitus position with the bleeding lung down). Control of Bleeding:
For minor hemoptysis, monitor and support with conservative measures.
In significant hemoptysis, consult respiratory or thoracic surgery early.
Tranexamic acid may be used to reduce bleeding.
Bronchoscopic intervention for localized bleeding may be necessary. Treat Underlying Cause:
Infections: Administer appropriate antibiotics or antituberculous therapy.
Malignancy: Refer to oncology for further management.
Cardiovascular Causes: Manage heart failure or pulmonary embolism as per guidelines.
Bleeding Disorders: Correct any coagulopathy with appropriate agents (e.g., vitamin K, fresh frozen plasma, platelets). Further Specialist Input:
Early involvement of pulmonologists, thoracic surgeons, or interventional radiologists is crucial for ongoing management and definitive treatment.
Hemoptysis can be a daunting presentation in the A&E. A systematic approach to history taking, examination, and investigation, combined with prompt management, is essential for optimal patient outcomes. As a junior doctor, maintaining a calm and methodical approach will help you navigate these cases effectively.
Remember, when in doubt, seek senior support and multidisciplinary input. Hemoptysis can be a sign of serious underlying pathology, and timely intervention can make all the difference.
