[Importance of cleansing in the topical treatment of skin lesions. A parallel study carried out in 20 patients and 30 rats]. / Importanza della detersione nel trattamento topico delle lesioni cutanee. Studio parallelo condotto su 20 pazienti e su 30 ratti.

ABSTRACT

There are frequent reports of the chronic nature of skin ulcers of varying etiology (burns, bedsores, wound diastasis, etc.); these heal with considerable difficulty probably due to problems related to the excessive use of disinfectants which, in spite of having a good bacterial action, interfere with re-epithelialisation processes. The aim of this study was to assess the value of simple wound cleansing instead of disinfection in those cases where there are no manifest signs of bacterial contamination. A widely sold solution, Katoderm (Devergè, Turin), was used in this study. The study was performed in two stages; the first in laboratory animals and the second in patients with small persistent lesions. The results of the study carried out in rats showed a significant prolongation of healing time in the group treated with polyvinylpyrrolidone-iodine compared to those in which lesions were only cleansed with Katoderm. The results of the clinical study also highlighted the faster speed of healing in patients treated with cleansing alone.
