8g2 Veterinary Obstetrics 



eu months prior to entrance she had been taken to a stallion for breeding, 

 and when the stallion groom examined her he thought that the os uteri 

 was much constricted. After using considerable force he succeeded in 

 passing one finger through the os. Immediately afterwards she was served, 

 but did not conceive. Since that time she had regularly shown signs of 

 estrum. Six months prior to entrance in our clinic, the owner observed 

 intermittent discharges from the vulva, of a thick, white, muco-purulent 

 character. At times while at work, she would discharge a large amount of 

 pus, and then for several days the discharge would virtually cease. 

 Examination revealed the OS uteri rigidly contracted. After repeated and 

 laborious attempts we succeeded in passing two fingers into the uterus. 

 We introduced a piece of rubber hose into the uterus, and withdrew seven 

 quarts of a thick, grayish-white viscid pus. We then washed the cavity of 

 the uterus repeatedly with i-iooo corrosive sublimate solution, after which 

 we introduced some two quarts of the solution into the cavity, and allowed 

 it to remain. We then packed the os uteri firmly with gauze. 



Internally we prescribed copper sulphate i — 1>^ oz., nux vomica 

 3 oz. , potassium iodide 5 oz., mixed and divided into twentjy-four powders, 

 of which two were directed to be given daily in the food. 



During the forcible dilation of the os, the mare strained violently and 

 offered considerable resistance. On April 26 the mare was straining a great 

 deal, though not very violently. After removing the pack, it was found that 

 the OS had dilated but little. The rubber hose was again introduced into the 

 uterus, and the cavity thoroughly washed out with a'solution of lysol. After 

 repeated injections until the siphoned fluid canfe away clear, we introduced 

 into the uterus a solution consisting of tannin i oz., carbolic acid i dram, 

 glycerine 4 oz. , water i pint . We then packed the os as tightly as possible, 

 after which she strained very violently. She was given one ounce each of 

 chloral and powdered ginger, which gave relief. 



On April 27 there seemed to be little progress in dilating the os by means 

 of the pack. After thorough disinfection of the parts, the os was forcibly 

 dilated until the hand could be passed into the uterus. The uterus and 

 horns were found greatly dilated, with thickened, paralysed walls. 

 After thoroughly irrigating the cavity with lysol solution, we deposited 

 about I dram of powdered iodoform in each cornu, and injected, and al- 

 lowed to remain in the uterus, the solution used upon the preceding day. 

 We then inserted into the os a gauze bag, which had been smeared with 

 iodoform and lard, and followed this by packing the bag as full as possible 

 of surgeon's cotton, saturated with corrosive sublimate solution. 



On the 28th we removed the pack, and found no accumulation of "pus. 

 The cavity was washed with lysol, after which the solution of carbolic acid, 

 tannin and glycerine of the preceding days was repeated. On April 29 ex- 

 amination showed that the uterine walls were resuming their normal condi- 

 tion and contractile power. The treatment of the previous day was repeated. 

 The same treatment was applied on the 30th, and the case was left without 

 interruption on May i. Examination on May 2 showed a small amount of 

 mucus in the uterus. The treatment of the previous days was repeated.
