How does spitting blood return a responsibility?

summary

We know that there are many ways to Treat Hemoptysis in clinic, which is commonly known as spitting. There are many ways, but the purpose of treatment is the same, mainly to inhibit the symptoms of rebleeding, of course, also to prevent airway obstruction, play the role of maintaining the life of patients. How does spitting blood return a responsibility? Let's talk about it

How does spitting blood return a responsibility?

Vascular wall erosion, rupture, pulmonary chronic infection makes vascular wall elastic fiber damage, local formation of small artery hemangioma, in severe cough or action, hemangioma rupture and massive bleeding, often cause asphyxia, sudden death, this kind of hemangioma is more common in cavitary pulmonary tuberculosis.

The increase of pulmonary intravascular pressure in patients with rheumatic heart disease, valvular stenosis, pulmonary hypertension, high blood pressure and heart disease can cause hemoptysis due to extravasation of blood or rupture of small blood vessels. Hemoptysis is caused by mechanical injury or calcification of pulmonary tuberculosis, mechanical injury of blood vessels caused by broncholithiasis.

Increased vascular permeability due to pulmonary infection, poisoning or vascular embolism, pathogens and other metabolites can cause direct damage to the microvascular wall, or increase the permeability of microvascular wall through the action of vasoactive substances. Red blood cells enter the alveoli from the dilated microvascular endothelial cell space and cause a small amount of hemoptysis.

matters needing attention

For patients with high fever, ice bags can be placed in the chest or head, which is conducive to cooling and hemostasis. We should pay attention to the early signs of asphyxia and prepare for the rescue of asphyxia. In case of massive hemoptysis and asphyxia, the body position drainage should be carried out immediately, and the hemoptysis should be poured out as far as possible, or the hemoptysis in the larynx or trachea should be sucked out with a suction device.
