Another appliance is known as Lund's truss.

 if saving the life of the patient must be attempted, 

 it will be necessary to rehiove the uterus by a surgical 

 operation, which is known technically as " Metrotomy."'

This is always a serious operation, and the number 

 of cases which terminate fatally is very considerable. 

 It has been estimated at 95 per cent. It should only 

 be attempted after the owner has been made aware of 

 the danger. 



Having decided to operate, puncture the uterine
