Typical symptoms of open pneumothorax?

summary

Open pneumothorax refers to the pneumothorax in which the air leakage channel of pneumothorax is continuously open and the gas enters and exits the pleural cavity with breathing. The cause of open pneumothorax is chest trauma, which is common in traffic accident injury, gunshot injury and explosive injury, resulting in chest wall defect. The pleural cavity communicates with the outside world, so that the air flows out through the chest wound, lung, trachea and esophageal laceration or soft tissue defect, and freely enters and leaves the pleural cavity with breathing, resulting in the disappearance of normal negative pressure. Typical symptoms of open pneumothorax? Let's talk about it

Typical symptoms of open pneumothorax?

Patients with open pneumothorax often have severe dyspnea, restlessness, weak pulse frequency, cyanosis and shock after injury. During the examination, there was an obvious wound in the chest wall leading into the chest, and the "hiss hiss" sound of air in and out with breathing could be heard. Percussion on the injured side showed that the tympanic sound disappeared, and sometimes the mediastinal swing sound could be heard.

The patient presented with restlessness, cyanosis, respiratory distress, sweating, decreased blood pressure, subcutaneous emphysema, and even shock. There is an open wound on the chest wall. When breathing, you can hear the sound of air coming in and out of the pleural cavity through the wound. The common signs were fullness of the affected side's chest, weakening of respiratory movement, percussion drum sound, trachea moving to the healthy side, and reduction or disappearance of respiratory sound.

If hemopneumothorax and peritoneal irritation exist at the same time, thoracoabdominal puncture should be performed as soon as possible. Thoracoabdominal puncture is a simple and reliable diagnostic method.

matters needing attention

Pay attention to traffic safety, avoid falling and stabbing, strictly grasp the operation indications in the medical process, and avoid iatrogenic pneumothorax.
