Soft tissue contusions of the chest usually recover and heal gradually in about two weeks, mostly from direct or indirect violence after trauma, and in severe cases, subcutaneous bruising, bruising, and even hematoma formation may occur. In the acute phase of the injury, ice should be applied, and in case of combined rib fractures, external fixation with chest straps should be chosen in time, and anti-infection treatment should be actively carried out. After 72 hours after the injury, local hot compresses can be applied to improve local microcirculation and reduce swelling and dissipate blood stasis. During the treatment period, we should pay attention to monitor the changes of chest X-ray or chest CT. If the patient has a hemopneumothorax or subcutaneous emphysema, the pain symptom will gradually worsen, and there will be obvious twisting sensation or grip snow feeling in the body, and if necessary, local skin incision is needed to fully exhaust and prevent infection.
