Mr. Chen, 54, has been suffering from gout since he was in his early 40s, and has been afflicted by the disease for more than 10 years, and walking is a problem when it is serious. In early October this year, Mr. Chen’s disease again, just in time for more work in the field, dragged a month, foot infection broke, the doctor said to amputate. Later, the orthopedic surgeon gave him a method of treatment for trauma to try, Mr. Chen’s foot saved. The reporter learned that this method is the first time to be used on gout patients. ”We are not specialized in treating gout, but we are good at dealing with trauma.” The doctor who received the case was a doctor from the second department of orthopedics in the hospital. After examination, it was found that Mr. Chen’s trauma was broken and swollen very much, and the extensive infection led to a large amount of purulent discharge. The trauma appeared to be a very small sinus tract on the surface, but inside was a large cavity. In order to save Mr. Chen’s foot, Dr. Yin came up with the idea of “negative pressure drainage”, which simply means that a sponge is placed over the wound to close it off and ensure ventilation while blocking the entry of bacteria. The other end of the tube is a negative pressure source that attracts the pus from underneath the wound and promotes the growth of soft tissue at the same time as the negative pressure drainage. On October 11, Mr. Chen went into the operating room and the doctor implanted a negative pressure drainage system for him, which worked very well. The reporter learned that on October 24, Mr. Chen was able to be discharged from the hospital, and his foot was saved.
