This method, however, of cleansing the parts is dangerous for the operator unless he takes the antiseptic precautions necessary in every case of delivery.
When the neck of the uterus is prematurely contracted, the difficulties become much greater, and are sometimes insurmountable on account of the impossibility of dilating it. It then becomes necessary to use metallic canulæ or uterine sounds made of aluminium in order to pass through the neck of the uterus. Liquids can be evacuated by compressing the uterus through the wall of the rectum, but the method is very troublesome.
This local treatment should be practised twice a day at least until all danger is over, and may be completed by the administration of diffusible stimulants, such as alcohol in doses of 6 to 10 ounces, acetate of ammonia in doses of 2 drachms, wine, coffee, and diuretic decoctions. These may be given with food or drink to whatever amount is considered necessary if the animals still retain their appetite. The food should be light and easily digested.
From 8 to 12 pints of physiological salt solution may be injected intravenously every day, the temperature at which this fluid is injected being varied according to the degree of fever. (Physiological salt solution consists of chloride of sodium 9 parts, sterilised water 1,000 parts.)
Prophylaxis. Should a case of septic metritis occur in a byre containing other cows about to calve the building should be disinfected.
ACUTE METRITIS.
The term “acute metritis” is used to indicate a variety of inflammation of the uterus of a sufficiently grave character, which, however, does not prove fatal in twenty-four or forty-eight hours.
Causation. In domestic animals acute metritis develops exclusively after difficult parturition and as a consequence of the tearing of tissues or accidental post-partum infection.
At one time it was the rule to recognise a traumatic form consequent on wounds by embryotomy hooks, crutches, cords, etc., etc. There is no reason for maintaining this distinction, because the essential condition for the development of metritis is the infection of the injuries.
Acute metritis follows non-delivery, incomplete delivery, or accidental infection.
