In the Ward of Children Surgery of the local Hospital 35 children from 0 to 15 years old with burn wounds of skin of different degrees have been treated. In surface, medium-deep and deep wounds regression of oedema, reddening and inflammatory reaction were observed already from 2nd day of treatment. Suppuration of wounds was not observed. It was observed that orthosilicon acid has anti-edematous and cooling (reduces pain) effect, quickens epidermization and shortens the time of appearing of granulation in deep burns. We think that orthosilicon acid is preparation worth further clinical testing of its usage in skin illnesses.
