• ABSTRACT
    • Hemoptysis is the spitting of blood that originated in the lungs or bronchial tubes. The patient's history should help determine the amount of blood and differentiate between hemoptysis, pseudohemoptysis, and hematemesis. A focused physical examination can lead to the diagnosis in most cases. In children, lower respiratory tract infection and foreign body aspiration are common causes. In adults, bronchitis, bronchogenic carcinoma, and pneumonia are the major causes. Chest radiographs often aid in diagnosis and assist in using two complementary diagnostic procedures, fiberoptic bronchoscopy and high-resolution computed tomography, which are useful in difficult cases and when malignancy is suspected. The goals of management are threefold: bleeding cessation, aspiration prevention, and treatment of the underlying cause. Mild hemoptysis often is caused by an infection that can be managed on an outpatient basis with dose monitoring. If hemoptysis persists, consulting with a pulmonologist should be considered. Patients with risk factors for malignancy or recurrent hemoptysis also require further evaluation with fiberoptic bronchoscopy or high-resolution computed tomography. In up to 34 percent of patients, no cause of hemoptysis can be found.
