The clinical manifestations of multiple rib fractures are as follows: 1. Pain, including resting pain, i.e., the patient will have persistent hidden pain in a quiet state. Respiratory pain is the pain that accompanies breathing pain, very regular pain. Active pain, i.e., when the pain when activity, usually the pain will be reduced when quiet.2, deformity, the fracture is often displaced, and the localization is obviously bulging, which is different from normal.3, abnormal respiratory movement, due to multiple rib fractures, the respiratory movement of the thorax is also obviously abnormal, the fracture site will not move along with the respiratory movement of the other normal parts of the body. When inhaling the normal thorax expands outward, negative pressure in the lungs, but the multiple rib fractures are instead attracted by the negative pressure and collapse, resulting in abnormal respiratory movement, which seriously affects the respiratory function.4. Pneumothorax, hemopneumothorax, the patient has chest pain, dyspnea, shortness of breath, palpitations, and other symptoms, which may be seriously life-threatening.
