Pleural shock

Introduction The lungs are collapsed and the extent of collapse depends on lung compliance and pleural adhesion. The normal pleural cavity is negative pressure, lower than the pleural cavity of the lesion side, causing the mediastinum to shift. At the same time, the pressure on the healthy side of the chest can still increase or decrease with the respiratory cycle, which causes the mediastinal swing and residual convection, leading to severe ventilation and ventilation dysfunction. The mediastinal swing causes the heart's large blood vessels to twist back and forth and the negative pressure in the chest cavity, which hinders the venous return and reduces the cardiac output. The mediastinal swing can stimulate the mediastinum and hilar plexus, causing or aggravating shock. The medical community calls it pleural lung shock.

Cause

The cause of pleural shock:

Infection, pneumothorax, etc. Pneumothorax refers to the gas entering the pleural cavity, resulting in a state of accumulation of gas, called pneumothorax. Usually divided into three categories: spontaneous pneumothorax, traumatic pneumothorax and artificial pneumothorax. Spontaneous pneumothorax is caused by rupture of lung tissue and visceral pleura due to lung disease, or by the rupture of tiny vesicles and pulmonary bullae near the surface of the lungs, and air in the lungs and bronchi into the pleural cavity.

1. Physical examination: The doctor performs routine examinations.

2, blood gas analysis: is commonly used in medicine to determine whether the body has acid-base balance disorders and hypoxia and hypoxia. Since the late 1950s, Poul Astrup of Denmark has developed the first blood gas analyzer. For more than 40 years, blood gas analysis technology has played a vital role in the diagnosis, surgery, rescue and monitoring of acute respiratory failure. With the rapid development of science and technology, the performance of blood gas analyzers has also been greatly improved.

Differential diagnosis

Diagnosis can be based on physical examination and blood gas analysis.

Differential diagnosis of pleural shock:

Hypovolemic shock: Hypovolemic shock refers to the pathophysiological process of effective circulating blood volume and cardiac output reduction, tissue perfusion, cell metabolic disorder and impaired function caused by loss of circulating capacity caused by various causes.

Abdominal pain with shock: abdominal pain with shock refers to abdominal pain accompanied by shock symptoms, common in acute intra-abdominal hemorrhage, acute obstructive suppurative biliary tract inflammation, strangulated intestinal obstruction, acute perforation of peptic ulcer, acute pancreatitis, acute abdominal organs Reverse, acute myocardial infarction, shock pneumonia.

Gravity shock: In order to supply sufficient nutrients and oxygen to the lower limbs that are strenuously exercising during the race, the blood vessels in the legs and feet will relax as much as possible to help the blood flow. If you stop and stand still after the race, due to the gravity of the heart, the blood will be deposited in the lower limbs, causing anemia in the brain, which will lead to pale, purple lips, and even fainting. This phenomenon is called "Gravity shock."

Hypoglycemic convulsions: Insulin shock is also called "hypoglycemia convulsions." Hypoglycemia shock symptoms caused by overdose of insulin or eating on time.

Collapse: Explosion is an acute syndrome that often occurs when fatigue, fear, pain, hunger, blood or strange monsters are seen. The patient appeared pale, sweaty, dizzy, nausea and vomiting, rapid heartbeat, blood pressure drop, some incontinence, and even fainted to the ground. If you can rest in the flat after the above symptoms, most people can gradually recover on their own. If you don't handle it properly, you will be struggling to walk, etc., which will aggravate your illness and even threaten your life. Because, at this time, it is mainly due to insufficient blood supply to the brain. If the problem can be solved quickly, the function of the brain will soon recover, and the dysfunction of the whole body can be quickly adjusted.
