690 DISEASES OF SWINE 



ing sows after a difficult birth. If the pains and straining continue 

 after the pigs have all been delivered, make certain that a dead pig 

 or an after-birth is not remaining in the uterus. If the organ ap- 

 pears to be empty, give agents that will check these severe contrac- 

 tions. Viburnum and opium, given as directed under the treat- 

 ment of abortion, are rehable agents. The viburnum opulus, how- 

 ever, rather than the viburnum prunifolium should be used. 



If the sow is not seen until after the uterus has slipped out, the 

 indication now is to return it to its normal position as quickly as 

 possible. It is a good plan before starting to work on the uterus 

 to empty the bladder if it be distended with urine. In some cases 

 this will be impossible. The first step in the handling of the everted 

 womb is to thoroughly wash off any dirt or other contamination 

 that may be on its surface. This should be done with a weak 

 solution of one of the coal-tar disinfectants. When this is ac- 

 comphshed the organ should be firmly wrapped with strips of 

 muslin bandage about 1 inch wide, commencing at the lowermost 

 part of the tumor mass. This forces the blood out of the womb and 

 reduces its size, making it much easier to return the organ to its 

 natural position. 



After the organ has been cleaned and wrapped it should be 

 pushed back into place. This is best done by taking a clean 

 finger or thumb and shoving forward against the center of the pro- 

 lapsed mass. In this way the uterus is returned to its normal posi- 

 tion and shape and reinverted, so as to bring it back into natural 

 relation with itself. 



When the uterus is back in place it is necessary to take some 

 precautions to prevent it slipping out again. This is done by plac- 

 ing two or three stitches across the vulval opening so as to make it 

 impossible for the tumor to again get out at that point. Viburnum 

 and opium may now be given for a few doses, to quiet the severe 

 contractions of the womb. These cases are always likely to be 

 followed by a severe infection, and it is wise precautionary treat- 

 ment to administer echinacea for several days to combat general 

 infection. 



In those cases that have been neglected, and where the uterus 

 has become decomposed and gangrenous, it is advisable to simply 

 amputate the organ, check the bleeding by stitches, and return the
