770 INDEX OF DISEASES AND REMEDIES 



HYDATID ON BRAIN OF SHEEP OR CATTLE. See WORMS. 



Ccenurus cerebralis ; tapeworm scolex or cyst. 

 Bore or trephine ; remove sac and contained heads. Success of operation 



depends on position and number of cysts. 

 Effectually treat all dogs with tapeworm, and prevent their eating 



hydatid- affected brains. 



HYDROCELE. 



Dropsy of scrotum. Rare in veterinary patients. 

 Evacuate by trocar and canula ; suspensory bandage ; observe antiseptic 



precautions. 

 Injection of dilute iodine or astringent solution. 



HYDROCEPHALUS. 



Chronic cranial dropsy, occasionally in horses, rare in cattle, dogs, or 

 swine ; also occurs in foetus and may hinder parturition. Arrests 

 brain development, producing gradual immobilite, when appearing 

 after third year. 



Treatment unsatisfactory. Quiet ; light but nutritive diet. 

 Pilocarpine, calcium phosphates, iron salts. 

 Trephine or puncture to relieve pressure and facilitate parturition. 



HYDROPHOBIA. See RABIES. 



HYDROTHORAX. 



Fluid (sometimes pus) in the chest. Affects all patients. 

 Digitalis ; pot. nitrate twice daily for a week. 

 Follow with pot. iodide and iron salts. 

 Pilocarpine hypodermically. 

 Iodine ointment and rubefacients externally. 

 When such measures ineffectual, and no diminution of fluid, or when 



dyspnoea increases, tap with trocar and canula, or aspirator ; operate 



antiseptically. 

 When pus present antiseptic irrigation of chest cavity may be tried, 



using one per cent. sol. protargol or lysoform, or one per thousand 



potassium permanganate. 



INDIGESTION. See DYSPEPSIA. 



INDIGESTION, ACUTE, OF HORSES. 



Stomach or grass staggers. 



Aloes eserine or calomel and oil to unload stomach and bowels. 

 Ether or spirit of ammonia every two hours overcomes flatulence and 



spasm. 

 Repeated copious laxative enemata, vigorous hand-rubbing of abdomen, 



and walking exercise, encourage action of bowels and relieve spasm. 

 Hot fomentations or cloths wrung out of hot water, and in-rubbing of 



mustard, abate spasm and pain. 



Where pain persists, morphine and atropine hypodermically. 

 One or two small doses of aconite tincture sometimes useful. 

 Blood-letting sometimes advisable where brain symptoms or dyspnoea 



occur. 



Paralysis resulting, give strychnine and apply counter-irritants to spine. 

 In young animals, where stomach overloaded with curd, prescribe oil, 



followed by ether or spirit of ammonia, and intestinal antiseptics. 



INFLAMMATION, ACUTE. 



Antipyretics, small doses in early stages, repeated three or four times 

 until pulse and temperature reduced. 



Place patient in suitable quarters ; ensure cool, pure air. 



Clothe body, bandage legs. 



Hot fomentations or poultices most useful where inflammation is com- 

 paratively superficial.
