208 VETERINARY STATE BOARD 



Describe the different methods of arresting hemorrhage. 



1. Ligation of the bleeding vessel by grasping the end with for- 

 ceps and tying with a strong thread. The vessel may be ligated at 

 a centripetal point. 



2. Compression with tampons and bandages, or by an elastic 

 bandage (Esmarch's bandage) applied between the wound and the 

 heart. 



3. Torsion, which consists of twisting the bleeding vessel on its 

 axis. 



4. Cauterization of the bleeding parts forms an eschar which 

 acts as an aseptic bandage. 



5. Cold contracts the vessels and narrows their lumen. 



6. Therapeutic agents as alum, sugar of lead, tannin, etc., applied 

 externally, by their astringent action, and ergot, adrenalin chloridcj 

 etc., internally, by their vasoconstrictor action, check hemorrhage. 



Give the treatment for lacerated wounds. 



Fresh lacerated wounds: arrest hemorrhage, irrigate, disinfect, 

 provide drainage, suture and bandage. If extensive and healing by 

 first intention is impracticable, apply drainage tube and suture as 

 much as possible. Remove drainage tube as soon as practicable and 

 secure healing by granulation. Old lacerated wounds may be scari- 

 fied, disinfected and sutured (healing by third intention), and if 

 this does not succeed, daily dressing and healing should be followed 

 by granulation and cicatrization. 



Give the care and treatment of a deep lacerated wound of the coronet. 



See answer to preceding question. 



Avoid excessive pressure in bandaging as it favors necrosis in 

 the region of the coronet. If the coronary band is much swollen, the 

 horn should be rasped away over an area corresponding to the 

 swelling. Horn formation should be discouraged until all swelling 

 disappears. Keep horn soft with .5 per cent, caustic potash solution 

 until the inflammatory swelling disappears. Irregular cicatrization 

 should be similarly treated. If abnormal growths of horn occur, 

 they should be rasped down. 



Mention the domestic animals in the order of their susceptibility to 

 suppuration. 

 From most susceptible to the least, as follows : horse, ox, sheep, 

 cat, dog, pig, fowls. 

 Give the method of arresting hemorrhage after castration in the colt. 



Cold irrigation, compression with tampons or ligation may be 

 employed. Generally, the preference is given to compression with
