56. DISEASES OF THE LUNGS 



high temperature may be absent, but if temperature be 

 present it falls by lysis. Dyspnea is usually seen indicating 

 a lack of aeration of the lungs. In the course of this secon- 

 dary bronchopneumonia the symptoms are not well marked 

 and depend largely upon the primary disease. 



Diagnosis. —This is made in the primary form by the sudden 

 onset with severe dyspnea, cough and high temperature, 

 while in the secondary form the symptoms, not being char- 

 acteristic, the diagnosis is more difficult, depending mostly 

 upon the dyspnea with its attending conditions. 



Prognosis.— Unfavorable. In the primary form the prog- 

 nosis is determined by the extent of the inflammatory process 

 in the lungs, while in the secondary form it depends upon the 

 causative disease, and as this is usually distemper the mor- 

 tality is high. 



Treatment.— Hygienic— The animal should be kept in a 

 warm, well ventilated room free from cold draughts. 



Dietetic— The animal's strength should be sustained by the 

 use of appetizing foods (milk, beef extract, etc.) given warm 

 in small quantities every few hours. During convalescence 

 small amounts of lean meat or other nutritious food may be 

 given 3 or 4 times a day. 



Medical.— At the onset a purgative should be given 

 (calomel 0.03 and sodium bicarbonate 0.5) to produce free 

 purgation and stimulate the activity of the kidneys. Expec- 

 torants are useful to modify and aid in expelling the discharge 

 from the bronchial tubes.

Counterirritants to the walls of the thorax in the form 

 of oil of mustard and glycerin (1-20) or Priesnitz compress 

 applied hot around the chest. The heart action should be 

 stimulated in severe cases by the use of digitalis fluid-extract 

 (0.08-0.1) and for general stimulation use strychnin (0.001). 

 Inhalations of medicated vapors (turpentine, oil of tar, 

 creolin in hot water) are useful to stimulate the mucous 

 membrane and to produce antiseptic action.
