How much compression of the pneumothorax requires puncture
In standard thoracic surgery, if the pneumothorax is greater than or equal to 30%, it is necessary to wear a puncture to aspirate, but in practice, the clinician will deal with it according to the actual situation of the patient, for example, the patient is a patient with emphysema, and the compression of the pneumothorax is less than 30%, but there are symptoms of chest tightness and shortness of breath and hypoxemia, even if he is less than 30%, he still needs to be punctured and aspirated.
However, it should be noted that for less than 20% of patients, if the pneumothorax is not well absorbed during observation and treatment, there is a tendency to gradually increase, or the patient's wheezing symptoms are obvious, thoracentesis closed drainage treatment is also required. First of all, let's understand what a pneumothorax is, pneumothorax refers to the entry of gas into the pleural cavity, which is what we call a cavity between the lungs and the chest wall, and the pleural cavity causes the state of the machine called pneumothorax.
How to treat pneumothorax
If the patient has severe dyspnea and the examination reveals a large amount of air in the pleural space, severe compression of the lung tissue, and even the compression of the lung tissue on the healthy side, it is necessary to immediately undergo thoracentesis or thoracostomys to expel the air to promote lung tissue rerecruitment and improve the recovery. Generally speaking, pneumothorax is divided into a small amount of pneumothorax and a large amount of pneumothorax, a small amount of pneumothorax can generally be treated conservatively, through oxygen infusion, bed rest, etc., a large number of pneumothorax, we often need to do a small operation, called thoracostomy, for the treatment of pneumothorax, we divide the pneumothorax into a small amount and a moderate amount, a large amount of pneumothorax. Mild pneumothorax can be cured after general treatment, but there is a possibility of recurrence later, mainly because the patient may be accompanied by some other lung diseases, such as chronic bronchia, emphysema, etc., which also need to be treated simultaneously.
CT findings of pneumothorax
Pneumothorax CT performance, we know that there is a potential gap between the lungs and the chest wall of normal people, but in normal times, this gap or cavity is a negative pressure state, this negative pressure can ensure that the lungs of normal people are tightly attached to the chest wall and the pleura, and there is a certain amount of lubricating fluid, which can make people inhale, between the lungs and the pleura and the chest wall, the thin layer is too much friction, resulting in pain, and if for some reason, such as very large alveoli or alveolar rupture, This causes air to enter this potential space or pleural space, which we call a pneumothorax.Chest x-ray is the most commonly used examination method for diagnosing pneumothorax, CT is more sensitive and accurate than chest x-ray for small pneumothorax, localized pneumothorax, and alveoli and pneumothorax. Pneumothorax CT has its special manifestation, which will manifest as a pneumothorax line, and the lung markings in the pneumothorax position will be significantly reduced or disappeared.
