Pelvic Constriction 68 1 



pelvic coustriction in the sow, bitch and cat. When dystokia 

 occurs in these animals from pelvic constriction, the obstetrist 

 should definitely decide upon the course to pursue. If hyster- 

 otomy is performed at all, it should be done at once, without 

 first attempting forced extraction or other manipulations in the 

 genital canal, since the inevitable insult to these parts and the 

 exhaustion of the patient greatly complicate the case and seriously 

 reduce the prospects for recovery should hysterotomy be later 

 decided upon.
