In addition, the transparency of Hydrosorb, which is
maintained even after prolonged use is particularly useful
in practice. It allows inspection of the wound without a
change of dressing. This ensures the non-disturbance of
the wound as well as being highly cost-efficient because
of the longer intervals between dressing changes.
