Study Notes

Pediatric Hemoptysis

  • Hemoptysis is coughing up blood or having blood in sputum, arising from the lungs.
  • Two vascular systems supply the lungs: the pulmonary arterial system (low pressure) and the bronchial system (high pressure).
  • Hemoptysis occurs when one of these systems is damaged.
  • Massive hemoptysis is defined as >8 mL/kg of blood loss over 24 hours, usually indicating high pressure bronchial damage.
  • Hemoptysis is rare in children younger than 6 years old due to sputum swallowing.
  • When evaluating a child with expectorated blood, determine the origin (extrapulmonary vs. upper airway vs. gastrointestinal).
  • Blood from extrapulmonary origins (e.g., upper airway or GI tract) may have different characteristics (e.g., color, pH, consistency).
  • Hemoptysis blood is bright red, often frothy, and alkaline.

Comparison of Hemoptysis and Hematemesis

Feature Hemoptysis Hematemesis
Sputum Features Bright red or pink, frothy, alkaline, liquid, with possible clots mixed with sputum Dark red or brown, potentially lower in GI tract, bright red if higher up, typically not frothy, acidic, with possible ground coffee-like appearance, may contain food particles
History No nausea or vomiting; possible history of lung disease; possible coughing or gurgling Nausea or vomiting; possible history of gastrointestinal or hepatic disease

Asking Questions

  • Detailed history of chief complaint: Timing and amount of blood; symptoms (associated fever, fatigue, runny nose, sore throat, coughing, weight loss, appetite changes, shortness of breath, pallor/cyanosis, pain).
  • History of recent infections, choking, trauma, aspiration.
  • Past medical history: Complications during perinatal/neonatal period and underlying conditions (Cystic Fibrosis, Ciliary dyskinesia, congenital diseases, rheumatic heart disease).
  • History of chronic lung disease (coughing, wheezing, stridor), surgeries.
  • Growth and development status.
  • Details of familial disorders and allergies; vaccination history; medications taken; travel history; infectious contact.

Physical Examination

  • Complete general physical exam including vital signs (blood pressure, heart rate, respiratory rate, temperature) and growth parameters.
  • Inspection: Body habitus, distress level, signs of trauma (bruising, swelling), chest wall expansion, symmetry, signs of collapsed lung/effusion.
  • Palpation: Chest area tenderness, masses, swollen lymph nodes, tactile fremitus, lung tenderness, consolidation/dullness, collapse, effusion.
  • Auscultation: Right (3 lobes) and left lungs (2 lobes) for abnormal breath sounds (localized wheezing, pleural rubs, pneumonia); bruits, thrills (arteriovenous malformation); heart murmurs (cardiac origin).

Differential Diagnosis

  • Infectious: Acute lower respiratory tract infections (Pneumonia [bacterial, viral, fungal, parasitic]).
  • Trauma: Aspiration (foreign body, especially <4 years old), contusion.
  • Bronchial Diseases: Bronchiectasis (cystic fibrosis, ciliary dyskinesia).
  • Vasculature: Pulmonary arteriovenous malformation, Alveolar hemorrhage syndromes, Connective tissue disease (Goodpasture syndrome, vasculitis), Pulmonary thromboembolism.
  • Neoplasms: Bronchial adenoma, metastatic cancer.
  • Other: latrogenic (damage from bronchoscopy).

Investigations

  • Laboratory: CBC, ESR, D-dimer, coagulation studies (INR, PTT), sputum sample for C&S.
  • Imaging: Chest X-ray; if insufficient, Chest CT scan; MRI for mediastinum and hilum structures, A.V. malformations (not always readily available).
  • Further: Bronchoscopy (if lab and imaging are insufficient in determining location/cause).

Treatment Plan

  • Treat the cause (e.g., mucolytics for symptomatic infections).
