308 WOUNDS AND THEIR TREATMENT. 



should b<3 emptied and irrigated and injected with an antiseptic 

 solution, afterward treated as an ordinary wound. 



Inflammation of the Lymphatics {Lymphangitis). This is 

 caused by poison absorbed from an unclean, unhealthy wound, 

 although in some instances it may be caused by a high nitrogenous 

 condition of the blood due to over-feeding. The author has 

 observed several cases in dogs where one or more of the legs was 

 hot, painful, and swollen, and there were also lameness and an 

 increase of temperature. On exiamining the subcutaneous lym- 

 phatics they were found to be enlarged, presenting a peculiar 

 corded appearance and running in the direction of certain of 

 the lymphatics. These were enlarged and very tender to the 

 touch. In cases of this kind we may see two terminations : first, 

 a rapid recovery; second, the formation of an abscess contain- 

 ing a large amount of purulent pus in the swollen lymphatic 

 glands, producing extensive inflammation, blood-poisoning, and 

 the animal eventually dying from septicaemia. 



The therapeutic treatment consists first in the irrigation of the 

 parts with cooling applications, and, if the glands show indications 

 of forming abscesses, apply hot poultices and open as soon as 

 possible. 



Inflammation of the Walls of the Bloodvessels {Phlebitis). 

 This is especially interesting to the veterinarian, as it is quite fre- 

 quently seen in the dog. Purulent inflammations of the blood- 

 vessels are seen in connection with infectious purulent wounds, and 

 originate as a secondary symptom by extension of the suppurating 

 process from the surrounding tissues. This is especially noticeable 

 where the wall of the vessel is crushed, forming a thrombus, and 

 this thrombus, lying in the bloodvessel, becoming infected from 

 the wound, produces suppuration and breaks down, and is carried 

 into the general circulation and deposited in some part or organ 

 of the body, setting up an irritation, and a consequent formation 

 of an abscess. This condition is termed " metastatic abscess." 



The therapeutics are the same as those of lymphangitis. Open 

 the wound as soon as possible and thoroughly disinfect the abscess. 



Fever. Concerning I he clinical symptoms of fever, we have 

 given all necessary details on page 23. The fever which accom- 

 panies wounds varies greatly in intensity according to the cause. 

 The following are the different varieties of wound fever :
