62 Bronchial Croup. 



of the oil mixtures, of each ]5-20 or 1.0 i^iii. Masson & Vazeux 

 have used creosote with good success in putrid bronchial ca- 

 tarrh (creosote 1.0, alcohol 40, aqua 40, of this mixture 20 cc. 

 twice daily). A 4% formalin solution might be used instead of 

 the creosote; sometimes, however, the former produces a pro- 

 longed irritation, which causes cough. To each one of these 

 solutions 1-2% tincture of opium might be added in order to 

 lessen the irritability of the mucosa. 



The value of internal medication is very doubtful. Expec- 

 torants and solvents of the mucus are in general use, for large 

 animals in the form of pills and electuaries, for small animals 

 in the shape of solutions. Such drugs are : stibium sulf . auran- 

 tiacum (10-20 or 0.5-1.0 pro dosi), ammonium chloratum 

 (8-15 or 0.2-1.0 gm.), root of senega (in a decoction 10:15 for 

 dogs) and root of ipecacuanha (0.5:15.0 in tablespoonful doses), 

 etc., 2-3% of liquor ammonii anisatus is added for smaller 

 animals. In a horse with bronchiolitis, Hermann had good 

 results by the repeated subcutaneous injection of iodipin (40-50 

 gm.). When there is al)undant secretion of mucus, especially 

 in the smaller bronchi, and difficulty in respiration depending 

 on it, emetics are indicated in smaller animals, since vomiting 

 raises the pressure and produces a stronger air current in 

 the l)ronchi, which favors the expulsion of masses of secretion. 

 Such drugs are: apomorphine hydrochlorate (0.005-0.01:50.0, 

 combined "with 0.05 gm. morph. hydrochlor. ; every three hours 

 a tablespoonful for dogs); tartarus stibiatus (1:100.0 every 

 fifteen minutes one tablespoonful); ipecacuanha (1-20:150 

 aqua), etc. Atropine (horses and cattle 0.03-0.05 gm., dogs, 

 0.002-0.01 gm., subcutaneously) has a tendency to suppress 

 excessive secretion and to relieve dyspnea for some time. 

 Priessnitz's applications may be made to the chest. 



The general condition must ])e watched in very young and 

 in very old animals and stimulants must be given in the pres- 

 ence of debility (camphor, ether, alcohol, caffeine). Larger 

 animals must be rublied down two to three times a day.

Bronchial Croup (Bronchitis crouposa). Cattle and sheep suffer 

 from a croupous inflammation of the bronchial mucosa under the same 

 conditions which bring about croup of the larynx, or it may be 

 secondary to nasal or laryngeal croup. In idiopathic bronchitis 

 crouposa the mucosa of all bronchi or of the majority of them is 

 covered bv tubular masses of fibrin. These masses interfere more
