Description

Disinfection of wound with povidone-iodine was thought to be very effective to wound healing.Nowadays wound infection is thought in the idea of bacterial balance, which means that bacteria are increasing in three phases‘: contamination’,‘colonization’and‘infection’. In the phases of‘contamination’and‘colonization’, the bacteria do not harm to the wound and disinfectants are not necessary but wound irrigation is recommended. In the phase of‘infection’, redness, swelling,local fever and tenderness are observed and disinfectants are needed.Dry condition was thought to be effective for wound healing to control the bacterial infection.However, it has been revealed that wound healing process is very complicated and needs many cells, growth factors and cytokines. Moist environment is useful for the movement of cells and factors to heal the wound.
