220 THEORY AND PRACTICE 



them. When a horse is to be raised with sHngs, never fail to 

 draw the water from him before raising him or rupture of the 

 bladder may occur. When no urine is secreted as in purpura 

 hemorrhagica, then the kidneys are at fault. 



Treatment. — When the urine is not secreted diuretics and 

 diffusible stimulants are indicated. If there is spasmodic con- 

 traction of the neck of the bladder, then anodynes should be 

 given, — as hot water and belladonna. Try passing the catheter 

 smeared with solid extract of belladonna. This will often relieve 

 the constriction. If you are sure of paralysis being present, 

 give one dram of powdered nux vomica in the feed night and 

 morning for a few days. 



The condition should be treated promptly and the animal not 

 neglected. Otherwise the case may become serious. 



ENURESIS. 



Enuresis is incontinuence of the urine. When the animal can- 

 not retain the urine in the bladder it dribbles away as it forms. 

 The condition is usually due to paralysis of the neck of the 

 bladder ; the muscles fail to contract and the urine dribbles down 

 the legs, scalding them. It is sometimes very painful. In the 

 male the penis becomes paralyzed and hangs down. 



Treatment. — Nerve tonics are indicated, with local shocking 

 such as dashing cold water on the perineum. This often resus- 

 citates the waning power. A gallon of water given per rectum 

 produces a shock and this comes in good in this condition. Nux 

 vomica taken continuously for a month will promote the general 

 health. 



Strangury is the passage of the urine in drops on account of 

 severe irritability of the mucous lining of the bladder or of the 

 muscularis. The urine comes away every few minutes in drops 

 or in small quantities. Apparently there is hyper?esthesia of the 

 bladder mucosa. The retention of the urine causes inflammation 

 of the bladder. 



The treatment must be toward allaying the irritability. 

 Therefore give anodynes such as opium, belladonna, etc., and 

 laxatives, — oil and linseed tea to drink,
