Patient: A few days ago, I bought Jenshi burn cream from the hospital, and after using it for a few days, the other wounds were obviously healed, but the thigh qi joint wounds were not healed and gradually became larger, and the subcutaneous area around the wounds was hollow. Blood flow is still possible. Is it because the gauze was too tightly stuffed during the medication change? Is the dressing too loose? Is it due to joint movement? The wound is now 1cm*1cm in size. I have the following medications: silver zinc cream, Acoxin dressing, carbon dressing, Mepore, Jane’s plaster, growth factor; disinfection with Bactrim. In your experience, what medication should I apply? How to change the medication? Please advise! Thank you very much! The results of the tests and bacterial samples: a small amount of Staphylococcus aureus, the joint was scalp implanted three times, the wound is small, but the joint is not moving well. The trauma is deep and depressed inside. It’s been four years since the trauma was repeated and I feel very bad! It is very painful! The trauma and the itch are always tormenting me? Doctor: It is normal for knee trauma to recur frequently due to activity, and both trauma and activity should be taken into account. Trauma dressing is divided into two steps: clearing and covering. For trauma without obvious infection, saline is good; for trauma with infection, iodophor and Bacrylate can be applied, and alcohol should not be used. For chronic wounds, it is better to apply silver-zinc cream and Jane’s plaster, and you can also spray growth factor; about dressing, Acosin has strong anti-infection ability and good carbon fiber adsorption (exudation is more used), and you can also add some Bactrim when the infection is heavy. But sometimes the repeatedly unhealed wounds also need surgical solutions.
