If the necrotic tissue in the affected area after a fracture is not cleared or if blood bruising has occurred, infection is more likely to occur. Therefore, in addition to the doctor’s need to completely clear the open fracture, the patient himself must also improve his immune system to avoid the possibility of infection. If there is an open fracture, the area must be completely emptied, such as necrotic tissue, and thoroughly removed. Otherwise, necrotic tissue and decaying tissue are good cultures for bacteria, and under the same physical conditions, it will easily lead to infection. After the second fracture, local hematoma will appear, blood stasis in this place, it is relatively normal people, the chance of infection will be much greater, we need to improve some immunity, increase some nutrition, you say diabetes, easy to cause immune deficiency disease, to actively give him control of blood sugar. The fracture will be less likely to be infected if the fasting blood sugar and relative immunity are improved. Of course, the infection after the fracture is still very few, because the infection of the fracture is very troublesome to treat, we must have this string in our head and must pay attention to it. Because bone infection is very troublesome to treat, osteomyelitis is sometimes a lifelong disease, chronic osteomyelitis, sometimes in order to save life, the arms and legs amputated, because I 79, for more than 30 years, at least three people have been amputated, or two people. Sometimes in order to save life, it year after year, the old abscess, the old infection get, the patient are annoyed, said I can not be completely cured, have, do not want, the arm and leg amputated. So the incidence of this infection is still very low. You like us in the operating room how to clear, with hydrogen peroxide, saline rinse clean, then use diluted iodine water and then soak, soak a three minutes, and then add saline rinse finished, then use hydrogen peroxide, aerobic bacteria, anaerobic bacteria how to deal with, that are in the operating room very professional problems, if it is an open fracture, in order to avoid infection, we must be completely empty.
