The main treatments for pneumothorax caused by chest puncture operation include observation treatment, exhaustion and drainage, prevention of recurrence treatment, and surgical treatment. 1. Observation treatment: patients should rest in bed, inhale oxygen and reduce talking, which is conducive to the recovery of pneumothorax. A few patients with mild symptoms of pneumothorax can return to normal with observation treatment. 2. Exhaustion and drainage: when the patient has obvious dyspnea and obvious lung atrophy, exhaustion and drainage is used. When exhausting, puncture the second intercostal space in the midclavicular line of the affected side, and then the gas will be gradually discharged by closed chest drainage, so that the compressed lungs will be gradually reopened. 3. Prevention of recurrence: pleural healing surgery can be used, in addition, patients should also have a reasonable diet and exercise to improve their immunity and prevent respiratory infections. 4. Surgical treatment: when serious symptoms appear, such as extreme respiratory difficulty, cyanosis, circulatory failure, etc., surgical treatment should be adopted in time. Pneumothorax caused by puncture should be diagnosed and treated early in the relevant departments of regular hospitals to avoid delaying the condition.
