HYDROMETRA AND PYOMETRA.

Cause: chronic metritis, tumors, microbian infection. Symptoms:

ill-health, low condition, vulvar swelling or discharge, swelling and

fluctuation of womb. Rectal exploration. Treatment: evacuate liquid,

disinfect womb and passages, creolin, iodine.

As a rule these conditions belong to obstetrics and would not come under

the scope of this volume, but when in chronic cases, with closure of the

neck of the womb, the liquids accumulate and distend the uterus, they

may deserve mention in a medical work.

The _cause_ is usually a chronic metritis, originating it may be at the

time of a now distant parturition, or associated with tumors or

microbian invasions of the womb. In the deadly cases that follow upon

parturition and abortion streptococcus is usually present, in the more

chronic forms the staphylococcus or other pus microbe.

The _symptoms_ are those of general ill-health, low condition, pallor of

the visible mucosæ, sometimes swelling of the vulva with discharge,

serous or purulent, lessened milk yield, enlargement of the abdomen with

fluctuation felt in the right flank, or still better with the hand in

the rectum. Rectal exploration will further detect the distended uterus

connected with the vagina behind and dividing in front into two horns.

_Treatment_ consists in the evacuation of the liquid through a catheter

or cannula introduced through the os, or through the vaginal wall

immediately above, followed by a systematic disinfection. By placing the

patient upon her back, gravitation of the liquid is more marked, but

when this is not convenient it may be done with the animal standing. The

flow may be favored by raising the abdomen with a sheet held by two

assistants. The womb may be thoroughly cleansed by a normal salt

solution which has been boiled, and then daily injected with a creolin

solution (1 ∶ 100). In hydrometra an iodine lotion may be used. A course

of tonics is often indicated.
