Is pulmonary contusion hemoptysis normal?

summary

Smoking not only affects my health, but also has adverse effects on the health of the people around me. The younger you start smoking, the higher your risk of lung cancer. Patients with advanced lung cancer will have a series of serious clinical manifestations, such as hemoptysis. At this time, the psychology of patients will feel very scared. Now let's share with you about whether hemoptysis is normal due to pulmonary contusion? Experience in this area.

Is pulmonary contusion hemoptysis normal?

The first is: hemoptysis is caused by coughing up blood, not coagulating, containing foam, bright red, mixed with mucus juice, and so on. A small amount of hemoptysis is due to the low pressure in the pulmonary artery, which is only about 1 / 6 of the aortic pressure. However, the vascular bed is rich and the blood flow is large. About 97% of the whole body blood flows through the pulmonary artery for gas exchange, so there is more chance of pulmonary artery hemorrhage. When the cancer cells infiltrate into the pulmonary vessels, the blood permeability increases, and pathogens and other metabolites can directly damage the microvessels, Or through the effect of vasoactive substances to increase the permeability of microvascular wall, red blood cells from the expansion of microvascular endothelial cells into the alveolar space and create a small amount of hemoptysis.

Second: there is another reason is the erosion and rupture of blood vessel wall. Chronic pulmonary infection can damage the elastic fibers of vascular wall and form small aneurysms locally. In severe cough or movement, the aneurysms rupture and bleed a lot, often resulting in asphyxia and sudden death. This is a serious hemoptysis, which is not common in lung cancer patients. General lung cancer patients belong to the former cause of hemoptysis, as long as the appropriate treatment, or can be controlled.

Third: the cause of lung cancer hemoptysis is due to the relationship between the tumor, blocking the gas channel, stimulating the bronchial wall, so that the trachea will have the reaction to expel foreign bodies, resulting in cough, sometimes coughing up sputum with blood, which is what we call hemoptysis; The blood coughed up by lung cancer patients usually comes from bronchi or alveoli. The blood coughed up does not contain food residue. If it contains food residue, it may be hematemesis rather than hemoptysis; When there is a tumor in the lung, it will cause local lung tissue inflammation, increase capillary permeability, and blood flow to the respiratory tract; Or tumor compression to microvessels, resulting in vascular rupture can also cause hemoptysis phenomenon.

matters needing attention

For the elderly, poor health, low immunity patients with advanced cancer, conventional western medicine treatment, may be able to achieve very good therapeutic effect, cancer cells can be very good to kill or control, but patients may not be able to withstand the side effects of the treatment process on the body loss, thus accelerating the end of the patient's life.
