320 BOVINE OBSTETRICS 



with fluid, as warm water or a weak lysol or creolin solution, to 

 smooth down any wrinkles. For this purpose I suggest a 1 per 

 cent, alum solution, provided no uterine wounds are present. 

 After a complete reposition the cow does not strain any more, 

 and should she continue to strain, an exploration must be made 

 at once to correct any partial inversions. 



It often happens that when the owner reduces the pro- 

 lapsus himself the cow continues to strain in spite of all means 

 employed to prevent it (curry-comb tied to the back, surcingle 

 or bandage around belly), professional aid only being employed 

 after a few days, when the general health becomes disturbed. 

 Internal examination then reveals that an inversio uteri is 

 present, cotyledons lying in the cervix or in the vagina. 



In those cases the treatment is as follows : The well-oiled 

 hand repels the inverted part, followed by immediate walking 

 exercise of the cow. After that the uterus is irrigated once 

 daily with a warm alum solution ; when necessary, a pessary 

 is employed. 



The quicker the contraction of the uterus and closure of 

 the cervix after reposition, the less the danger of a recurrence. 

 Therefore, little pieces of ice are frequently introduced into the 

 uterus to encourage contractions. The main point in the after 

 treatment therefore consists in the prevention of a new pro- 

 lapsus, most readily effected by a complete reposition. There 

 are many means employed to prevent it, which maybe divided 

 into two main groups : (1) means which prevent inversio uteri ; 

 and (2) means which only prevent the expulsion of the pro- 

 lapsed uterus from the vulva. 



To the first group belong the pessaries. They prevent 

 the inverted uterus from passing through the cervix into the 

 vagina. 



St. Cyr and Violet describe a simple pessary, termed by 

 them Gariel's pessary, consisting of a rubber pouch and tube. 

 The pouch is folded, introduced into the uterus, inflated and 

 closed by means of a small stopcock. The whole is a modifica- 

 tion of Willburg's pessary (Baumeister), he introducing a pig's 

 bladder and inflating it.
