'" 'Treatment. Rest and pure" ^ir are 'tllb' nfloWpot^n-tfactcyrs' 

 in securing speedy relief from bronchial catarrh. Hence the 

 patients must be kept in uniformly warm, clean places, the 

 barns must be well aired and the sojourn in the open, in sunny 

 places free from draft, is to be favored. Larger animals 

 should not be used for work during the whole duration of an 

 attack of bronchial catarrh, even if it is confined to the larger 

 bronchi. The feed should consist of easily digestible, dust-free 

 material containing an abundance of water; as a drink the pa- 

 tients should have pure, if possible slightly alkaline, not too cold 

 water. Frequent and tormenting cough, particularly in the 

 initial stage, should be ameliorated by the same narcotics which 

 are recommended for laryngitis (see page 42). In the further 

 course, after the secretion has become more abundant and more 

 liquid, its expulsion must not be prevented by a suppression 

 of the cough. 



In dry bronchitis sojourn in moist air exerts a favorable' 

 influence and this treatment is particularly serviceable in the 

 case of smaller house animals which are usually kept in rooms. 

 The contents of the air in water vapor can "be increased by 

 placing flat vessels filled with water hear the stove or radiator 

 or by the use of a spraying apparatus. The object of fre- 

 quent inhalations is the same. The benefits derived from them 

 must, however, not be overestimated, because it has been shown 

 experimentally that vapors and finely divided fluids are depos- 

 ited already in the nose and pharynx, so that only a small part 

 of them can get into the deeper respiratory passages. For in- 

 halation purposes the same substances may be used which were 

 recommended against laryngitis (see page 42). If the exhaled 

 air has a fetid odor, one may usei a finely divided spray of cor- 

 rosive sublimate (1 :2000) ;" 2-3% solution of creolin; 1-2% 

 solution of carbolic acid. Tn intense dyspnea due to ah exten- 

 sive bronchiolitis the administration of oxygen may become 

 necessary. 



The intratracheal injection of drugs can only have an in-'v 

 significant place in practice. Aside from the fact that the method-"- 

 ical carrying out of such treatmeht meets with difficulties the 

 ingested fluids (as shown by Earner) only get into the larger 

 bronchi of the anterior pulmonary portions and the watery 

 solutions are there absorlied too rapidly. A certain success 

 might be expected after the injection of larger masses of fluids 

 or after oil in emulsions. The following are adapted for intra- 

 tracheal injections: sodium bicarbonate (2-3%); zinc sul-. 

 phurate (Vi'%) ; argentum nitrate (0.1%), also LugoPs solution 

 (1:5: 100-200), and oil of turpentine (with olive oil al). 

 Larger animals receive from 20-40 gm. of the watery solutio^ns ; . 

 sm'^lter animals 2-3 gm. at one dose injected into the trachea?)
