NONCONTAGIOUS DISEASES OF RESPIRATORY ORGANS. 99 



HEMOPTYSIS. 



Hemoptysis is a term used to signify bleeding from the lungs. The 

 trouble may result from a previous congestion of the lungs or from 

 a breaking down of the lung substance, or from specific disorders. 



Bleeding from the lungs comes from both nostrils and from the 

 mouth. The blood is bright red, frothy, and accompanied with a 

 cough, the flow being somewhat profuse and intermingled with mu- 

 cus. It may cease of its own accord. Internally hemostatics are in- 

 dicated, and locally over the sides cold applications have a tendency 

 to check the hemorrhage. A drench of 1^ drams of gallic acid dis- 

 solved in a pint of water should be given. 



ABSCESS OF THE LUNG. 



Abscesses of the lung sometimes form during the course of or sub- 

 sequent to tuberculosis or other diseases. An animal affected with 

 abscess of the lung usually has a protracted, feeble cough and a gen- 

 eral appearance of emaciation and anemia. The pulse is feeble and 

 the breath foul. An offensive discharge from the lungs frequently 

 occurs. Percussion and auscultation aid in making a diagnosis in 

 this condition. The appetite is poor. Such animals go from bad 

 to worse, and their prompt destruction would, as a rule, be to the 

 interest of the owner. 



HYDROTHORAX. 



Hydrothorax, or dropsy of the chest, is not a disease in itself, 

 but is simply a condition in which an effusion takes place in the 

 chest cavity, and is the result or effect of some disease, mostly pleu- 

 risy. It can be easily diagnosed by physical signs. A loss of the res- 

 piratory murmur will be noticed on auscultation, and on percussion 

 dullness or flatness on a line as high as the effusion has taken place. 

 When a large amount of effusion is present, tapping with the trocar 

 and cannula is generally resorted to. The proper method of per- 

 forming this operation will be found under the head of " Pleurisy." 



PNEUMOTHORAX. 



An accumulation of gas in the pleural sac is known as pneumo- 

 thorax. The presence of air may result from either an injury of the 

 lung or a wound communicating from the exterior. The indications 

 for treatment are to remove any foreign body that may have pene- 

 trated, to exclude the further entrance of the air into the cavity by 

 the closure of the external opening, and to employ antiseptics and 

 adhesive dressings. The air already in the cavity will in most cases 

 be absorbed.
