304 BOVINE OBSTETBICS 



parturient passage it is drawn in further and severed. This is 

 followed by agglutination and recovery, provided the uterine 

 secretion is aseptic. 



Many veterinarians successfully order cold applications to 

 the loins to encourage contractions of the uterus. 



Franck insists that iu post partmri paralysis the bruised 

 uterus (cervix uteri) may reflexly produce paralysis of the pos- 

 terior extremities. He states that this reflexory paralysis in 

 one or both limbs, originating in the uterus, is also seen in 

 man, and adds : " They frequently disappear on thorough 

 cauterization of the offending portion of the uterus." 



Schurink also describes a case in which post partum 

 paralysis was due to injury of the uterus. 



INJURIES OF THE VAGINA. 



Most injuries of the vagina take place during parturition. 

 They may occur when extraction is attempted during violent 

 pains with the calf in an abnormal position. "With one fore 

 leg flexed at the carpus and retained, and the other leg and 

 head lying normally, limited traction suffices to tear the vaginal 

 wall, already tense. Rough manipulations during reposition 

 may cause injuries. 



A common cause of vaginal wounds is the slipping of the 

 hooks or injury by sharp pieces of bone, the result of em- 

 bryotomy. 



Symptoms. — In many cases the wound is only detected on 

 vaginal exploration. Penetrating wounds are characterized by 

 a more general disturbance, wanting appetite, straining and 

 symptoms of peritonitis. 



In eventration a piece of the omentum is mostly found in 

 the vagina, especially when the wounds are in the lower wall 

 and near the external os uteri. In those cases the owner 

 calls the veterinarian because he sees a piece of fat, often 5 cm. 

 wide, protruding from the vulva. 



Large penetrating wounds may be followed by a prolapse 

 'of the intestines. Eventration increases on account of the per- 

 sistent straining.
