DISEASES OF THE DOMESTIC ANIMALS 



and acceleration of the pulse and breathing. Examination of the 

 chest shows sibillant and rhonchus rales, followed by moist sounds. 

 Absence of dulness on percussion and blowing breathing on auscult- 

 ation distinguish it from pneumonia. Prevention is accomplished 

 as in coryza (see p. 65). 



Bronchitis usually follows coryza by extension and is due to 

 the same causes ; also to poor ventilation, as during transportation 

 of animals, and to irritants in air, as dust and smoke. It is symp- 

 tomatic of many special infections, as influenza, distemper, etc., 

 and may arise from ingesta of vomitus being drawn into the 

 trachea. 



Treatment. — The treatment consists generally in attention to 

 hygiene, and in shortening the attack and relieving symptoms. It 

 is possible that a full dose of opium may abort the disorder (H., 

 pulvis opii 3i ; D., liquid Dover's powder Tt],x) when given at the 

 onset, if, at the same time, the equine patient is covered with a hot 

 blanket, rubber sheet and dry blanket, and the limbs are rubbed with 

 mustard paste and bandaged. The retention of a wet pack about the 

 chest and bandaging of the limbs, as above, is useful throughout the 

 attack. The food should be laxative (H., bran mashes, roots, grass) 

 and the bowels moved by oil or enema, and there must be plenty of 

 fresh air, which is aided by the use of a box-stall. In the first stage, 

 secretion should be promoted; give inhalations of sodium bicar- 

 bonate (3 ss to the pint of boiling water or lime water) three times 

 daily. At this time, if there is much fever, the following prescrip- 

 tion may be employed :
