  8. 8. Haemoptysis is the coughing of blood originating from the respiratory tract below the level of the larynx. Haemoptysis should be differentiated from:<br />Haematemesis - vomiting of blood from (GI) tract.<br />Pseudohaemoptysis - where a cough reflex is stimulated by blood not derived from the lungs or bronchial tubes. This may be from the oral cavity or nasopharynx or following aspiration of haematemesis into the lungs.<br />
  9. 9. Classifications of severity vary: <br />
  10. 10. Massive haemoptysis has been arbitrarily defined as a loss of between 100-600 ml blood over 24 hours. It is a life-threatening medical emergency. This highly variable amount is based on the fact that the anatomic dead space in most adult is 100-200ml.<br />
  11. 11. <ul><li>Vascular Anatomy of the Lung:
  12. 12. The pulmonary and bronchial circulation </li></li></ul><li>Bronchial Circulation: <br /> Is the source of bleeding in the majority of cases of hemoptysis and it also represents the source of most episodes of massive hemoptysis, because it arises from aorta and is under systemic pressure.<br />
  13. 13. <ul><li>Mechanisms by which massive hemoptysis is produced include the following : </li></ul> 1/ Chronic parenchyma inflammation leading to erosion of bronchial and vascular walls ,enlargement and proliferation of bronchial vessels, and formation of anastamoses between bronchial and pulmonary circulation and formation of bronchiectasis or lung abscesses. 2/ Various vascular alteration, such as aneurismal formation,vasculitis and embolism. <br /><ul><li> 3/ Erosion of a calcified lymph node into the tracheobronchial tree. 4/ vascular invasion by tumor. </li></li></ul><li>Pulmonary Circulation : <br /> Is a low-pressure circuit with normal pressures of 15-20 mmhg systolic and diastolic . Aneurysms,AVMs,and iatrogenic are common causes of hemoptysis.<br />
  14. 14. Non-Bronchial Systemic Collateral Circulation: Systemic arteries may cross the pleural space and neovascularize the lung in a number of disease processes associated with inflammation of the lung parenchyma and the pleura.<br />
  15. 15. Etiology<br />
  16. 16. According to source of bleeding:1<br />Trachea or bronchus: <br />Malignancy <br />Bronchogenic carcinoma<br />Endobronchial metastatic tumor<br />Kaposi's sarcoma<br />Carcinoid tumour<br />Bronchitis<br />Bronchiectasis<br />Broncholithiasis<br />Airway trauma<br />Foreign body<br />
  17. 17. Lung parenchyma: <br />Lung abscess<br />Pneumonia - bacterial (e.g.Staphylococcus aureus, Pseudomonas aeruginosa) or viral (e.g. influenza)*<br />Tuberculosis (TB)<br />Fungal infection and mycetoma<br />Hydatid cysts<br />Goodpasture's syndrome<br />Pulmonary haemosiderosis<br />Wegener's granulomatosis<br />Lupus pneumonitis<br />Lung contusion<br />"Crack" lung<br />
  18. 18. Vascular: <br />Arteriovenous malformation<br />Aortic aneurysm<br />Pulmonary embolism (PE)<br />Mitral stenosis<br />Other cause of pulmonary venous hypertension, e.g. left ventricular failure (LVF)<br />Trauma<br />Iatrogenic (e.g. chest drain malposition, secondary to pulmonary artery catheter manipulation)<br />
  19. 19. Other: <br />Pulmonary endometriosis<br />Congenital or acquired systemic coagulopathy, e.g. leukaemia<br />Anticoagulant or thrombolytic agents<br />Factitious haemoptysis<br />
  20. 20. Infection : <br /> Tuberculosis / <br /> Rupture of Rasmussen aneurysms, which represent small ectatic portions of pulmonary arteries traversing thick walled cavities of chronic tuberculosis. <br /> Bronchial artery erosions from parenchymal/airway necrosis and tubeculous bronchiectasis. <br /> Chronic cavitary disease predisposing to the formation of secondary infections, such as mycetomas.<br />
  21. 21. Chronic Airway Inflammation : <br /> Bronchiectasis ; Hemoptysis occur in 25-50%, present as a single massive episode of hemorrhage, or intermittent blood streaking intermixed with purulent sputum. In this condition ,the bronchial arteries are hypertrophied and ecstatic ,and accompanied by enlarged sub mucosal anastigmatic plexi in the bronchial walls.<br />
  22. 22. Neoplastic Diseases <br />Bronchogenic Carcinoma Approximately 7-10% of pt with BC present with a history of blood-streaked sputum or expectoration of small clots. In a large retrospective analysis of 877 pt with lung cancer, massive, terminal hemoptysis was noted in 29(3%).This report and other studies have confirmed that those present with massive hemoptysis secondary to lung cancer typically have a centrally located cavitary sqamous cell carcinoma.<br />
  23. 23. Epidemiology<br />
  24. 24. Incidence<br />Haemoptysis is common. In most cases, it is mild, self-limiting and related to transitory infection but it should be considered a serious sign due to the risk of underlying pathology. In the past, tuberculosis was a major cause but in the UK today, the majority of cases of haemoptysis are due to acute upper and lower respiratory tract infections, with lung cancer a much smaller but significant cause.<br />
  25. 25. . In another UK primary care study, haemoptysis had a 7.5% positive predictive value for lung cancer in men and 4.3% in women, rising to 17.1% in men aged between 75-84 years. Haemoptysis has been considered a useful clinical sign of pulmonary embolism.<br />
  26. 26. Risk factors<br />Male >female.<br />Middle to older age (>40 years increases the risk of a malignant cause).<br />
  27. 27. Presentation<br />may find it hard to identify the origin of their bleeding.<br />Haemoptysis or haematemesis?<br />
  28. 28. Haemoptysis Haematemesis<br />No nausea or vomiting Nausea and vomiting<br />Concurrent lung disease Concurrent gastric or hepatic disease<br />Sputum is frothy Vomitus is rarely frothy<br />Sputum has a liquid or clotted appearance Typical coffee ground appearance<br />Haemoptysis is bright red or pink Haematemesis is brown to black<br />Alkaline pH Acidic pH<br />Mixed with macrophages and neutrophils Mixed with food particles<br />
  29. 29. Symptoms<br />Abrupt onset cough, fever with bloody and purulent sputum - suggestive of acute pneumonia or bronchitis.<br />Chronic productive cough - suggestive of chronic bronchitis or bronchiectasis.<br />Fevers, night sweats and weight loss - consider TB and other infections or malignancy.<br />Anorexia, weight loss and changing cough - think of possible bronchogenic carcinoma.<br />Dyspnoea, fatigue, orthopnea, paroxysmal nocturnal dyspnoea, frothy pink sputum - suggestive of congestive heart failure.<br />Anxiety, dyspnoea and pleuritic chest pain - consider a PE<br />
  30. 30. Always enquire about:<br />Tobacco use.<br />Travel history - consider potential exposure to histoplasmosis, coccidioidomycosis or schistosomiasis.<br />Weight loss.<br />Occupational history - particularly, exposure to asbestos, arsenic, chromium, nickel and ethers<br />
  31. 31. Signs<br />Record vital signs, including oxygen saturation levels. Fever, tachycardia, tachypnoea, weight loss and hypoxia are all relevant. Check for cachexia, cyanosis, pallor, ecchymoses, telangiectasia and lymphadenopathy.<br />
  32. 32. Inspect the nasal cavity and oropharynx for: <br />Extrapulmonary causes (pseudohaemoptysis)<br />Signs of vasculitis<br />Saddle nose, and nasal perforation suggest Wegener's granulomatosis. Orofacial and mucous membrane telangiectasia are associated with Osler-Weber-Rendu syndrome.<br />Perform a cardiovascular examination. Significant signs may include: <br />The diastolic murmur of mitral stenosis.<br />Signs of LVF.<br />Tachypnoea, tachycardia, fixed split S2, pleural rub, and unilateral leg pain or swelling may indicate thromboembolic disease.<br />
  33. 33. Lung signs that may be found with haemoptysis include: <br />Fine inspiratory rales (alveolar blood).<br />Inspiratory and expiratory rhonchi (associated with airway secretions and blood).<br />Look for evidence of an exacerbations of chronic obstructive pulmonary disease or lower respiratory tract infection. Unilateral wheeze and distal consolidation raise the suspicion of endobronchial tumour. Unilateral wheeze or stridor may also indicate the presence of a foreign body. With apical dullness and cachexia, TB should be considered.<br />
  34. 34. Digital clubbing can reflect chronic lung disease (lung cancer, bronchiectasis, lung abscess).<br />Supraclavicular lymphadenopathy, cachexia, hoarse voice, Cushing's syndrome, hyper pigmentation, and Horner's syndrome are all associated with malignancy.<br />
  35. 35. Investigations<br />Dependent on the clinical setting but these may include: FBC, ESR, U&Es, coagulation studies, urinalysis, arterial blood gases, sputum cytology and culture, acid-fast bacillus (AFB) smear and culture, D-dimer testing, and HIV test.<br />
  36. 36. Imaging - CXR +/- CT scan. About 30% of patients with haemoptysis have normal CXRs. Look for:1<br />Cavitations (e.g. TB, necrotising pneumonia).<br />Segmental or lobar atelectasis (obstructions due to lung cancer, bronchial adenoma, foreign body).<br />Left atrial enlargement, Kerley B lines (mitral stenosis).<br />Thickened bronchial walls (bronchiectasis).<br />Lymphadenopathy.<br />Infiltrates<br />
  37. 37. Fibreoptic bronchoscopy enables direct visualization and is required where there is a mass on CXR, there are risk factors for cancer despite normal CXR, or where diagnosis remains open, particularly in instances of recurrent haemoptysis.<br />
  38. 38. Electrocardiogram (ECG) +/-echocardiogram (ECHO) - if a cardiac cause or PE is suspected.<br />
  39. 39. Management<br />Treatment is according to the underlying cause.<br />
  40. 40. Minor haemoptysis<br />Effort should be concentrated on determining the origin of the haemoptysis, providing specific treatment where available and excluding serious underlying pathology.<br />Normal CXR, history consistent with bronchitis - oral antibiotic, advise smoking cessation and follow-up in a few weeks.<br />Consider chest CT scan and bronchoscopy where: <br />Haemoptysis lasts longer than 2 weeks.<br />There are recurrent episodes of haemoptysis.<br />The volume of haemoptysis is >30 ml per day.<br />The patient is a smoker and >40 years old.<br />There is suspected bronchiectasis.<br />
  41. 41. All smokers or ex-smokers aged >40 years with persistent haemoptysis should urgently be referred to a chest physician under the two-week wait rules.<br />
  42. 42. Moderate haemoptysis<br />Moderate haemoptysis (30-50 ml in the previous 24 hours) requires hospitalization for observation, due to increased risk of further heavy bleeding.<br />Nurse in the semi-sitting position when awake and with abnormal lung down when lying in bed.<br />Consider cough suppression with codeine but avoid over sedation.<br />Await bronchoscopy - diagnostic yield is often highest when performed a few days after bleeding has stopped.<br />
  43. 43. Major haemoptysis<br />This is a medical emergency. However, there are few large, good-quality, controlled trials looking at best management to guide practice - particularly in the medical versus surgical dilemma.<br />
  44. 44. Resuscitate according to 'ABC' principles. <br />Intubate where there are signs of acute respiratory failure. Selective intubation of the right or left main bronchus with a large single-lumen endotracheal tube.<br />Maintain oxygenation saturations with high flow oxygen and suction.<br /> Obtain IV access and give fluids/blood transfusion as appropriate. <br />Octreotide and other vasopressor drugs are sometimes used to control acute life-threatening bleeding. <br />Correct any clotting abnormalities. <br />The patient will require admission to intensive care.<br />
  45. 45. Localization of the bleeding site via radiology and early bronchoscopy. CXR and even CT scanning may not bechoscopy remains controversial and tends to depend on local preference and expertise helpful (due to the presence of aspirated blood). The use of rigid or flexible fibreoptic born.<br />
  46. 46. Specific therapies to control bleeding: <br />Bronchoscopic therapy: <br />Iced saline lavage.<br />Topical agents, e.g. use of thrombin or fibrinogen-thrombin glue.<br />Endobronchial balloon catheter tamponade.<br />Laser photocoagulation. <br />
  47. 47. Angiography and embolisation - bronchial artery embolisation is an important technique, developed from the care of patients with cystic fibrosis (CF), who were not candidates for surgery. It may be used as definitive treatment or a bridge to surgery. Major complications are now rare, the most feared being spinal cord infarction. Initial control of bleeding is achieved in over 90% of CF patients, although recurrent bleeding occurs in 22-46%.<br />
  48. 48. Surgical resection: <br />Segmentectomy<br />Lobectomy<br />Pneumonectomy<br />Under emergency conditions, surgery is difficult, has a high risk of septic complications and a significant mortality rate.<br />
  49. 49.  <br />Radiotherapy - may be used to treat aspergillomas and vascular tumours.<br />
  50. 50. Palliative care<br />Haemoptysis is the presenting complaint in 7-10% of lung cancers and about 20-30% patients with lung cancer will experience it over the course of their illness. In 3%, massive haemoptysis is the terminal event. Management of haemoptysis in the context of a malignant disease depends on the volume of blood loss, its cause and prognosis. Given the bleak prognosis of a massive haemoptysis, active resuscitation may not be desired or appropriate. <br />
  51. 51. . Under these circumstances, the emphasis should be on the relief of pain and of fear in the patient and supporting witnesses and family:<br />Nurse lying on the side of the tumour.<br />Administer parenteral opioid and fast-acting benzodiazepine.<br />
  52. 52. With more minor haemoptysis, additional palliative care measures may include:<br />Oral haemostatics, e.g. tranexamic acid.<br />Cough suppression.<br />Anticoagulation (where PE).<br />Antibiotics (where infection).<br />Radiotherapy or laser treatment of the tumour site.<br />
  53. 53. Prognosis<br />Haemoptysis may be a mild, self-limiting symptom or may herald serious underlying disease. Massive haemoptysis can directly cause death and has a bad prognosis, worse in some groups such as those with an underlying cancer. Risk of recurrence is associated with haemoptysis lasting more than five days and with a concurrent lung cancer diagnosis.<br />
  54. 54.  IV vasopressin (Argipressin) is occasionally useful - the paediatric dose is 0.3 units/kg (maximum 20 units) over 20 minutes followed by 0.3 units/kg/hour (maximum 1 unit/kg/hour) continued for 12 hours after bleeding has stopped and gradually withdrawn over 24-48 hours (maximum duration 72 hours).  It can lead to water intoxication and can cause bronchoconstriction. IV terlipressin (for children >12 years) has fewer side effects; dose is 2mg then 1-2mg every 4-6 hours until bleeding is controlled, (maximum duration 72 hours); this is used by the adult unit. <br />
  55. 55. Oral tranexamic acid has been used long term in recurrent bleeders with some success. Dose is 15-25 mg/kg tds (max 1.5 g/dose). <br />
