TRAUMATIC LESIONS. 129 
or leuchemia, slight traumatisms are often accompanied by consider- 
able hemorrhages, which are sometimes fatal; in dogs affected with 
ganglionary leuchemia (adénie), the extirpation of a single ganglionary 
mass is followed by abundant hemorrhage, very difficult tostop. Trau- 
matisms of operations, or those that are accidental, may be followed by 
inflammatory or septic complications. 
Among visceral diseases, affections of the heart give rise to a circulatory. 
trouble which may produce dyspncea, cedema, ascites, or hydrothorax. 
On that account the wounds of patients affected with these bleed pro- 
fusely ; sometimes, besides, there are vascular alterations. Cidema, 
which occurs in patients affected with heart disease, expose them, as in 
those affected with albuminuria, to erysipelas and to phlegmons. In 
patients with heart-affections, traumatisms may bring on phenomena of 
asistole. Diseases of the liver (cirrhosis, fatty and amyloid degeneration) 
carry with them numerous disorders—interference with the circulation, 
digestive troubles, alteration of the blood—which have a great influ- 
ence on the progress of the traumatisms. These become the seat of a 
hemorrhage difficult to stop, and of diffuse inflammation ; they are 
often accompanied by erysipelas, lymphangitis, profuse suppuration, 
and these predispose to pyohzmia and septicemia. Traumatisms are 
not without influence upon the evolution of hepatic. affections; they 
may stimulate in them a sudden aggravation. 
Finally, all acute diseases, accompanied with intense fever, and in 
particular infections, act on traumatisms and interfere with the repair- 
ing process. Let us also mention as such, age, species, breed. 
Traumatic lesions of diseased tissues present some peculiarities and 
expose them to complications which vary according to the alterations 
of those tissues. In hyperzmic parts or those affected with acute in- 
flammation, hemorrhage is always abundant, and the cicatrization by 
first intention rare: complications of diffused inflammation, phleb- 
itis, lymphangitis, are frequent. Wounds of suppurating surfaces ex- 
pose the patients particularly to erysipelas, lymphangitis, pyohzmia 
and tetanus; therefore, as far as possible, one should avoid injuring 
those wounds. When traumatisms involve tissues already altered by 
chronic inflammation, the consecutive phenomena are sometimes nearly 
like those which take place in sound tissues; at others, one will notice 
a return of the phlegmasia to an acute stage, the suppuration increas- 
‘ing, after which recovery takes place; then again the wound may 
assume an ulcerative character.
