RURAL VETERINARY SECRETS 21 



In acute catarrhal laryngitis the course is usually six to ten 

 days, ending in complete recovery. Neglected cases may become 

 chronic and last for months, causing persistent, obstinate cough, 

 but usually no further symptoms. 



TREATMENT 



The patient should be allowed fresh air (not too cold) free 

 from drafts, dust and stable gases. If the weather permits, exer- 

 cise in the open should be allowed. In mild attacks horses may be 

 employed at light work, provided they are protected against high 

 wind or drenching rains. The food should be laxative (roots, 

 grass) and free from dust. 



Hot applications to the throat are valuable. During the early 

 stages inhalations of medicated steam are of service. See directions 

 for steaming in acute nasal catarrh and give the same medical treat- 

 ment. If you suspect the cause to be of an infectious nature, separate 

 the well from the sick and thoroughly disinfect the stable. 



CROUPOUS LARYNGITIS 



A disease of the larynx and laryngeal mucosa in which the 

 pharynx and trachea are also involved. This is rather rare, occur- 

 ring mostly in sheep and cattle and more rarely in horses and swine. 

 It is caused usually by inhaling irritating gases, smoke, strong 

 fumes of disinfectant, and sometimes from driving through dust 

 to increase the weight of wool. 



SYMPTOMS 



In the beginning the symptoms are the same as in catarrhal 

 laryngitis, except that the patient becomes more rapidly emaciated 

 and loses appetite. There is also a swelling and sensitiveness of 

 the throat. 



TREATMENT 



The treatment consists of the same medicinal agents and in- 

 halations of medicated steam as in catarrhal laryngitis, except that 

 a tracheotomy tube might be used in addition in the early stages 

 of the disease.
