If the patient's health is below par, good nourishing food, tonics, and

_Management of a Healing Sore._--Perhaps the best dressing for a healing
sore is a layer of Lister's perforated oiled-silk protective, which is
made to cover the raw surface and the skin for about a quarter of an
inch beyond the margins of the sore. Over this three or four thicknesses
of sterilised gauze, wrung out of eusol, creolin, or sterilised water,
are applied, and covered by a pad of absorbent wool. As far as possible
the part should be kept at rest, and the position should be adjusted so
as to favour the circulation in the affected area.

The dressing may be renewed at intervals, and care must be taken to
avoid any rough handling of the sore. Any discharge that lies on the
surface should be removed by a gentle stream of lotion rather than by
wiping. The area round the sore should be cleansed before the fresh
dressing is applied.

preparation). The growth of epithelium may be stimulated by a 6 to 8 per

Dusting powders and poultice dressings are best avoided in the treatment
of healing sores.
