Hemoptysis
Frightening to the patient, hemoptysis is the expectoration of blood or bloody sputum from the lungs or tracheobronchial tree. It’s sometimes confused with bleeding from the mouth, throat, nasopharynx, or GI tract. (See Identifying hemoptysis, page 350.) Expectoration of 200 ml of blood in a single episode suggests severe bleeding, whereas expectoration of 400 ml in 3 hours or more than 600 ml in 16 hours signals a life-threatening crisis.
Hemoptysis usually results from chronic bronchitis, lung cancer, or bronchiectasis. However, it may also result from inflammatory, infectious, cardiovascular, or coagulation disorders and, rarely, from a ruptured aortic aneurysm. In up to 15% of patients, the cause is unknown. The most common causes of massive hemoptysis are lung cancer, bronchiectasis, active tuberculosis, and cavitary pulmonary disease from necrotic infections or tuberculosis.
A number of pathophysiologic processes can cause hemoptysis. (See What happens in hemoptysis, page 351.)
Emergency Actions
If the patient coughs up copious amounts of blood, endotracheal intubation may be required. Suction frequently to remove blood. Lavage may be necessary to loosen tenacious secretions or clots. Massive hemoptysis can cause airway obstruction and asphyxiation. Insert an I.V. line to allow fluid replacement, drug administration, and blood transfusions, if needed. An emergency bronchoscopy should be performed to identify the bleeding site. Monitor blood pressure and pulse to detect hypotension and tachycardia, and draw an arterial blood sample for laboratory analysis to monitor respiratory status.
History
If the hemoptysis is mild, ask the patient when it began. Has he ever coughed up blood before? About how much blood is he coughing up now and about how often? Ask about a history of cardiac, pulmonary, or bleeding disorders. If he’s receiving anticoagulant therapy, find out the drug, its dosage and schedule, and the duration of therapy. Is he taking other prescription drugs? Does he smoke? Ask the patient if he has had any recent infections. Has he been exposed to tuberculosis? When was his last tine test and what were the results?
Physical assessment
Take the patient’s vital signs and examine his nose, mouth, and pharynx for sources of bleeding. Inspect the configuration of his chest and look for abnormal movement during breathing, use of accessory muscles, and retractions. Observe his respiratory rate, depth, and rhythm. Finally, examine his skin for lesions.
Next, palpate the patient’s chest for diaphragm level and for tenderness, respiratory excursion, fremitus, and abnormal pulsations; then percuss for flatness, dullness, resonance, hyperresonance, and tympany. Finally, auscultate the lungs, noting especially the quality and intensity of breath sounds. Also auscultate for heart murmurs, bruits, and pleural friction rubs.
Obtain a sputum sample and examine it for overall quantity, for the amount of blood it contains, and for its color, odor, and consistency.
Medical causes
Bronchial adenoma
Bronchial adenoma is an insidious disorder that causes recurring hemoptysis along with a chronic cough and local wheezing. The patient with bronchial adenoma may also have recurrent infection, dyspnea, and wheezing.
Bronchiectasis
With bronchiectasis, inflamed bronchial surfaces and eroded bronchial blood vessels cause hemoptysis, which can vary from blood-tinged sputum to blood (in about 20% of patients). The patient’s sputum may also be copious, foul-smelling, and purulent. He may exhibit a chronic cough, coarse crackles, clubbing (a late sign), fever, weight loss, fatigue, weakness, malaise, and dyspnea on exertion.
Bronchitis (chronic)
The first sign of chronic bronchitis is typically a productive cough that lasts at least 3 months. Eventually this leads to production of blood-streaked sputum; massive hemorrhage is unusual. Other respiratory effects include dyspnea, prolonged expirations, wheezing, scattered rhonchi, accessory muscle use, barrel chest, tachypnea, and clubbing (a late sign).
Coagulation disorders
Such coagulation disorders as thrombocytopenia and disseminated intravascular coagulation can cause hemoptysis. In addition to their specific related findings, coagulation disorders may share such general signs as multisystem hemorrhaging (for example, GI bleeding or epistaxis) and purpuric lesions.
Laryngeal cancer
Hemoptysis occurs in laryngeal cancer, but hoarseness is the usual early sign. Other findings may include dysphagia, dyspnea, stridor, cervical lymphadenopathy, and neck pain.
Lung abscess
In about 50% of patients, a lung abscess produces blood-streaked sputum resulting from bronchial ulceration, necrosis, and granulation tissue. Common associated findings include a cough with large amounts of purulent, foul-smelling sputum; fever with chills; diaphoresis; anorexia; weight loss; headache; weakness; dyspnea; pleuritic or dull chest pain; and clubbing. Auscultation reveals tubular or cavernous breath sounds and crackles. Percussion reveals dullness on the affected side.
Lung cancer
In patients with lung cancer, ulceration of the bronchus commonly causes recurring hemoptysis (an early sign), which can vary from blood-streaked sputum to blood. Related findings include a productive cough, dyspnea, fever, anorexia, weight loss, wheezing, and chest pain (a late symptom).
Pneumonia
In up to 50% of patients, Klebsiella pneumonia produces dark brown or red (currant-jelly) sputum, which is so tenacious that the patient has difficulty expelling it from his mouth. This type of pneumonia begins abruptly with chills, fever, dyspnea, a productive cough, and severe pleuritic chest pain. Associated findings may include cyanosis, prostration, tachycardia, decreased breath sounds, and crackles.
Pneumococcal pneumonia causes pinkish or rusty mucoid sputum. It begins with sudden shaking chills; a rapidly rising temperature; and, in over 80% of patients, tachycardia and tachypnea. Within a few hours, the patient typically experiences a productive cough along with severe, stabbing, pleuritic pain. The agonizing chest pain leads to rapid, shallow, grunting respirations with splinting. Examination reveals respiratory distress with dyspnea and accessory muscle use, crackles, and dullness on percussion over the affected lung. Malaise, weakness, myalgia, and prostration accompany high fever.
Pulmonary contusion
Pulmonary contusion, resulting from blunt chest trauma, commonly causes a cough with hemoptysis. Other signs and symptoms appear gradually within several hours after the injury and include dyspnea, tachypnea, chest pain, tachycardia, hypotension, crackles, and decreased or absent breath sounds over the affected area. Severe respiratory distress — with oppressive dyspnea, nasal flaring, use of accessory muscles, extreme anxiety, cyanosis, and diaphoresis — may develop at any time.
Pulmonary edema
Severe pulmonary edema commonly causes frothy, blood-tinged pink sputum, which accompanies severe dyspnea, orthopnea, gasping, anxiety, cyanosis, diffuse crackles, a ventricular gallop, and cold, clammy skin. This life-threatening condition may also cause tachycardia, lethargy, cardiac arrhythmias, tachypnea, hypotension, and a thready pulse.
Pulmonary embolism with infarction
Hemoptysis is a common finding in this life-threatening disorder, although massive hemoptysis is infrequent. Typical initial symptoms are dyspnea and anginal or pleuritic chest pain. Other common clinical features include tachycardia, tachypnea, low-grade fever, and diaphoresis. Less commonly, splinting of the chest, leg edema, and — with a large embolus — cyanosis, syncope, and distended jugular veins may occur. Examination reveals decreased breath sounds, pleural friction rub, crackles, diffuse wheezing, dullness on percussion, and signs of circulatory collapse (weak, rapid pulse; hypotension), cerebral ischemia (transient loss of consciousness, convulsions), and hypoxemia (restlessness and, particularly in elderly patients, hemiplegia and other focal neurologic deficits).
Pulmonary hypertension (primary)
Features of primary pulmonary hypertension generally develop late. Hemoptysis, exertional dyspnea, and fatigue are common. Angina-like pain usually occurs with exertion and may radiate to the neck but not to the arms. Other findings include arrhythmias, syncope, cough, and hoarseness.
Pulmonary tuberculosis
Blood-streaked or blood-tinged sputum commonly occurs in pulmonary tuberculosis; massive hemoptysis may occur in advanced cavitary tuberculosis. Accompanying respiratory findings include a chronic productive cough, fine crackles after coughing, dyspnea, dullness to percussion, increased tactile fremitus, and possible amphoric breath sounds. The patient may also develop night sweats, malaise, fatigue, fever, anorexia, weight loss, and pleuritic chest pain.
Silicosis
Initially, silicosis causes a productive cough with mucopurulent sputum. Subsequently, the sputum becomes blood-streaked and, occasionally, massive hemoptysis may occur. Other findings include fine, end-inspiratory crackles at lung bases, exertional dyspnea, tachypnea, weight loss, fatigue, and weakness.
Systemic lupus erythematosus
In 50% of patients with systemic lupus erythematosus (SLE), pleuritis and pneumonitis cause hemoptysis, cough, dyspnea, pleuritic chest pain, and crackles. Related findings are a butterfly rash in the acutephase, nondeforming joint pain and stiffness, photosensitivity, Raynaud’s phenomenon, convulsions or psychoses, anorexia with weight loss, and lymphadenopathy.
Other causes
Diagnostic tests
Lung or airway injury from bronchoscopy, laryngoscopy, mediastinoscopy, or lung biopsy can cause bleeding and hemoptysis.
Special considerations
If necessary to protect the nonbleeding lung, place the patient in the lateral decubitus position, with the suspected bleeding lung facing down. Perform this maneuver with caution because hypoxemia may worsen with the healthy lung facing up.
Prepare the patient for diagnostic tests to determine the cause of bleeding. These may include a complete blood count, a sputum culture and smear, chest X–rays, coagulation studies, bronchoscopy, lung biopsy, pulmonary arteriography, and a lung scan.
Pediatric pointers
Hemoptysis in children may stem from Goodpasture’s syndrome, cystic fibrosis, or (rarely) idiopathic primary pulmonary hemosiderosis. Sometimes, no cause can be found for pulmonary hemorrhage occurring within the first 2 weeks of life; in such cases, the prognosis is poor.
Geriatric pointers
If the patient is receiving anticoagulants, determine any changes that need to be made in diet or medications (including over-the-counter and natural supplements) because these factors may affect clotting.
Patient counseling
Comfort and reassure the patient, who may react to this alarming sign with anxiety and apprehension. Hemoptysis generally ceases (but not abruptly) during treatment of the causative disorder. Many chronic disorders, however, cause recurrent hemoptysis. Instruct the patient to report recurring episodes and to bring a sputum specimen containing blood if he returns for treatment or reevaluation.
