If it is a small amount of pneumothorax, the physical signs are generally not obvious, especially when patients with emphysema develop pneumothorax, it is difficult to detect any signs. However, when a larger amount of pneumothorax occurs, inspection will reveal that the affected side of the chest is bulging and respiratory movements are reduced. Upon palpation, the trachea usually shifts towards the healthy side, tactile fremitus on the affected side is reduced, percussion results in hyperresonance or tympany, and auscultation shows reduced breath sounds, which can disappear in severe cases.

How is the fluid in pneumothorax drained?

Pneumothorax with effusion is mostly due to trauma or structural issues in the lungs themselves, leading to lung rupture, accompanied by intrathoracic hematomas, effusion, or pneumothorax. This condition is known as hydro-pneumothorax. Generally speaking, the treatment method depends on the severity of the hydro-pneumothorax. Usually, a mild case can be absorbed by the patient naturally. However, if the pneumothorax occupies more than 30% of the thoracic cavity, closed thoracic drainage should be implemented, along with the removal of pleural effusion for absorption to take place. Of course, the specific disease must be clearly identified, which might require repair, tumor resection, or anti-tuberculosis treatment to ultimately address the cause of the disease.

Pneumothorax tracheal shift to which side?

When a patient suffers a pneumothorax, the trachea is displaced to the opposite side, and the heart is also shifted to the opposite side. In cases of left-sided pneumothorax, the heart's dullness boundary and the upper boundary of the liver during right-sided pneumothorax are both undetectable. There can be manifestations of subcutaneous emphysema in the neck, chest, and even the head and abdomen. The patient may exhibit diminished respiratory movements and a significant reduction or absence of breath sounds. When a small amount of air accumulates in the pleural cavity, weakened breath sounds on the affected side may be the only suspicious sign.

How to treat recurrent pneumothorax for the second time?

Patients with recurrent pneumothorax, we recommend proactive minimally invasive surgical intervention. For patients experiencing their first recurrence of pneumothorax, the likelihood of a second recurrence is about 20-30%. For those who have had two episodes of pneumothorax, it indicates the presence of a small rupture on the lung, or an area that has not healed well, or is particularly weak. Thus, for patients who have had two episodes or a second occurrence of pneumothorax, if they do not receive active treatment, the probability of a third recurrence rises to about 70-80%. Whether using minimally invasive surgery or the conservative method of simple tube insertion, both are certainly burdensome for the patient. However, for patients with a second occurrence of pneumothorax, undergoing a small minimally invasive surgery, which involves a small incision of one to two centimeters under the armpit to treat the pneumothorax, dramatically reduces the likelihood of subsequent occurrences from the previous 70-80% to below 10%. Therefore, the best treatment for a second pneumothorax episode is through minimally invasive surgical intervention.

Can you smoke with pneumothorax?

After suffering from pneumothorax, patients often experience symptoms such as chest pain, chest tightness, and coughing. Can patients smoke after suffering from pneumothorax? It is advised against smoking after suffering from pneumothorax, as smoke and harmful substances directly irritate the respiratory tract, worsening the patient's symptoms. Additionally, smoking produces a large amount of carbon monoxide, which, when absorbed by the body, can cause hypoxia, thereby exacerbating symptoms of breathing difficulty. Therefore, patients with pneumothorax should not smoke, and it is also recommended to quit smoking even after recovery from pneumothorax, as smoking is harmful in many ways and particularly damaging to the respiratory system.

Pneumothorax auscultation what sound?

Pneumothorax is a common medical emergency. After suffering from a pneumothorax, symptoms often include chest tightness, difficulty breathing, and coughing. Regarding lung auscultation by a doctor after pneumothorax, the sound heard primarily depends on the amount of air accumulated. If the air accumulation is minimal, the physical signs may not be obvious. If there is a substantial amount of air, the breathing sounds during auscultation are reduced. In cases of a large pneumothorax, the breathing sounds may disappear, while on the healthy side, the breathing sounds may be coarser and intensified. Therefore, if pneumothorax is suspected during a lung auscultation examination, an immediate imaging test should be conducted to confirm the diagnosis.
