The key points of first aid for multiple multiple rib fractures are as follows. First, the most important thing is to observe the patient’s vital signs. Vital signs include temperature, pulse, blood pressure, and respiration. If there are fluctuations in vital signs, a significant decrease in blood pressure, shortness of breath, and a weak and rapid pulse, it is necessary to suspect that the patient has internal organ damage. Rib fractures can easily be combined with spleen rupture and lung damage, as well as liver damage, the most dangerous of which is spleen rupture and hemorrhage. It is important to avoid life-threatening bleeding from the spleen. If the lung injury causes coughing, coughing and difficulty in breathing, it is also a very serious complication. If the patient does not have a combination of visceral injury and the vital signs are still stable, a comprehensive judgment of the fracture should be made, whether the fracture needs to be reset and fixed, bandaged for protection, and medication applied externally to promote healing.
