Wound iodophor wiped white, the common reason may be the proliferation of fibrous tissue, and granulation tissue is stimulated by the following: 1, proliferation of fibrous tissue: the wound itself is accompanied by more fibrous tissue hyperplasia, as well as secretion, this situation through the iodophor wiped the surface of the secretion, it will be exposed to the local hyperplasia of fibrous tissue, manifested as a local color of the pallor. This does not belong to the local infection, do not worry too much, strengthen the dressing, keep the wound clean, can promote the local wound faster recovery. 2, the granulation tissue is stimulated: some patients, although the local granulation is relatively fresh, but the iodophor coating, there may be a greater concentration of iodophor, for the fresh granulation tissue caused by stimulation, manifested as pale color. This situation requires the replacement of disinfectant liquid, if necessary, only saline for local disinfection, or the use of concentrated sodium chloride continuous wet compresses, which can avoid the continuous edema of local tissues, so that the wound can recover faster.
