should be trimmed, and all tissue that is so torn and detached as to
interfere with healing cut away. Drainage for the wound secretions and pus
should be provided. The advisability of suturing the wound depends on its
character and location. A contused-lacerated wound should not be closed
with sutures unless it is clean and shows no evidence of sloughing. A badly
infected wound should be left open unless satisfactory drainage for the pus
and wound secretions can be provided. Wounds across the muscle and in parts
that are quite movable should not be sutured.

_The after-treatment_ consists in keeping the animal quiet, if the wound is
in a part that is quite movable, and preventing it from biting, licking or
nibbling the injury. Wounds in the region of the foot become irritated with
dirt and by rubbing against weeds and grass. This makes it advisable to
keep the animal in a clean stall until healing is well advanced. Local
treatment consists in keeping the wound clean by washing the part daily, or
twice daily, with a one per cent water solution of a cresol disinfectant.
Liquor cresolis compositus may be used. It is sometimes advisable to
protect the granulating surface against irritation by dusting it over with
a non-irritating antiseptic powder, or applying a mixture of carbolic acid
one part and glycerine twelve parts. After the wound shows healthy
granulations longer intervals should lapse between treatments.

In poorly cared for, and badly infected wounds, the part may become badly
swollen, the granulations pile up and the wound refuse to "heal over." It
may be advisable in such cases to cut away the excessive granulations and
stop the haemorrhage by cauterization with a red-hot iron, or by
compression. Unhealthy granulations may be kept down by applying caustic
occasionally.
