According to the degree of lung contusion and the depth of the effusion, medication or surgery can be chosen. 1. Mild pulmonary contusion effusion: if only mild pulmonary contusion, pay attention to rest; for a small amount of pulmonary effusion, considering the combination of inflammation and infection, oral cefixime anti-inflammatory, and then combined with furosemide to improve the leakage of fluid in the chest cavity. 2. Severe pulmonary contusion effusion: if it is a more serious pulmonary contusion, mechanical ventilation should be used as soon as possible to prevent acute shock; for those with hypovolemic shock, blood volume should be replenished in time. When there is a large amount of pleural effusion and the patient has symptoms such as chest tightness, shortness of breath, dyspnea, etc., thoracentesis needs to be done as soon as possible, and the chest can be opened and explored if necessary. If there is currently found to be a lung contusion, it is recommended to seek timely medical treatment, and through X-ray, CT or ultrasound to understand the extent of the injury, and then observe the depth of the effusion, and according to the results of the targeted treatment. Drugs need to be used under the guidance of a doctor, avoid self-medication.
