Smoking chest pain

Introduction The thin and tall young men between the ages of 20 and 30 are the main prosthetic groups of spontaneous pneumothorax. Most patients have family tendencies and smoking habits. According to statistics, the rate of diarrhea among smokers is nine to eleven times higher than that of non-smokers. Patients have chest pain, chest tightness, and shortness of breath, and the majority of chest pain is manifested. Due to the young, tall and thin reasons, patients often do not care, ignoring the importance of medical examination. This disease is one of the pulmonary emergency, severe cases can be life-threatening, timely treatment can be cured.

Cause

The pleural cavity is a closed cavity between the visceral-parietal pleura. Due to the elastic retractive force of the lung, it is a negative pressure chamber [-0.29 ~ 0.49 kPa (-3.5 cm H2O)]. When a certain cause causes the alveolar pressure to rise sharply, the lung-pleural rupture of the lesion ruptures, the pleural cavity communicates with the atmosphere, and the airflow flows into the chest cavity to form a spontaneous pneumothorax. Spontaneous pneumothorax is mostly secondary, because some patients' lung tissue has been adhered to the parietal pleura. When the pneumothorax is formed, the lung tissue ruptures the pupil or the bronchiole pleural pupil can not be closed with the compression of the lungs, causing the pupil to remain open. The chest pressure is close to zero, and it becomes an "open pneumothorax"; some patients form a flap like bronchoconstriction and semi-occlusion, so that air enters the chest cavity during inhalation, and is still left here when exhaling. The chest pressure can exceed 1.96 kPa. (20cmH2O), become a "tensional pneumothorax"; due to the above reasons, spontaneous pneumothorax is often difficult to heal, re-ventilated chest, localized pneumothorax is more common, and simple closed pneumothorax is less.

Pulmonary examination of lung and pleural auscultation for pulmonary ventilation

Usually no history of respiratory diseases, but there may be large alveolar pleura under the pleura. Once the rupture forms a pneumothorax called spontaneous pneumothorax; spontaneous pneumothorax occurs in a thin and tall body, the ratio of male to female is 6:1.

It is usually judged by a doctor's auscultation and percussion, or by X-ray examination. If the symptoms are mild, there will be discomfort such as difficulty in breathing, chest pain, chest tightness, etc. If left untreated, it may cause subcutaneous emphysema. In severe cases, even the lungs may shrink and shock.

Differential diagnosis

Pleural disease

Such as pleurisy, spontaneous pneumothorax, chest pain caused by these diseases is related to breathing and cough. Chest pain is aggravated during deep breathing and coughing, often accompanied by difficulty breathing. Chest pain is located on one side of the lesion.

Cardiovascular diseases

It is represented by angina pectoris and myocardial infarction, followed by pericarditis. This type of chest pain is often manifested in the precordial area and post-sternal compression, squeaky pain, and even tearing pain. Often radiated to the left shoulder, neck and the inside of the left arm, with severe symptoms of shock.

Intercostal neuritis, herpes zoster, esophagitis

Can cause chest pain, severe chest pain when the herpes zoster, along the intercostal space, 1 to 2 days after the skin appeared dense small blisters.

Some abdominal organ lesions cause chest pain

Such as underarm abscess, acute cholecystitis, acute pancreatitis.

Chest trauma

Common in rib fractures, history of chest trauma, increased chest pain when breathing or coughing.
