GANGEENE 85 



What parts of the body are more frequently affected by moist 

 gangrene ? 



The flexion surface of the fetlock in gangrenous der- 

 matitis, the lateral cartilage in quittors, the coronary region,, 

 the sensitive laminae, the region of the neck, poll and back, 

 the subcntis, fasciae, and muscles, as in fistulous states ; the 

 interdental space in pullers, the udder of goats, cows, and 

 sheep, etc. 



OuUine the treatment of gangrene. 



Prevent it by removing as far as possible its causes, and 

 promote the circulation of the parts. When a serious inflam- 

 matory process threatens to terminate in gangrene, free 

 incision of the parts may relieve the tension, as, for in- 

 stance, in strangulated hernia, incision of the constricting- 

 ring. When gangrene is unavoidable, prevent infection and 

 decomposition by thorough disinfection, and establish drain- 

 age to get rid of the fluids of decomposition retained beneath 

 the gangrenous cover, followed by frequently changed anti- 

 septic dressings. If gangrene localizes itself, hasten separa- 

 tion by warm antiseptic poultices, and after the part has 

 cleaned off, treat same as an ulceration. Should the necrotio 

 process continue to spread, amputate the affected part, pro- 

 vided economic reasons permit such a course, as in gangrene 

 of the udder, tail, tip of the tongue, ears, claws, penis (after 

 paraphimosis). 



What constitutional treatm,ent is indicated in gangrene ? 



In those cases of moist gangrene with tendency to spread 

 aiid involving the deeper parts, absorption of ptomaines is 

 likely to occur. These are forced into the lymphatic channels 

 and connective tissue spaces along fasciae and tendon sheath 

 (septic synovitis), or a thin walled vein may succumb to the
