Method 1:
Utensils: cotton swabs, gauze or detoxified paper, potassium permanganate, erythromycin ointment, forceps, methylnitrogen solution.
Operation: Cotton swabs and cotton cloth for wiping pus and blood must be clean and detoxified. This treatment needs to be done multiple times, so you can't be lazy.
The first step is to clean up the rotten flesh and pus blood in the fish head hole, and then fill the hole with potassium permanganate, one of the things that must be noted is to remember not to put potassium permanganate on the eyes of the fish.
After filling, seal the head hole with erythromycin ointment to prevent the drug from flowing out.
The time for changing the dressing is once every two days, and the rotten meat in the fish head hole should be cleaned up again each time the dressing is changed, and the standard of cleanliness is to see a small amount of blood flowing out. In addition to potassium permanganate, wounds can also be filled with metronidazole and sealed with erythromycin ointment.
