drained should be irrigated witli antiseptic solution. Make 

 long and deep incisions where fluctuation is present; in 

 sutifacial and intermuscular cellulitis, inject quantities of 

 slightly warmed glycerine 10, iodoform 1 part. The in- 

 ternal treatment is of little value (excepting intravenous 

 injections of soluble silver) ; nevertheless, stimulate with 

 fearless doses of strychnine, digitalis ; give tonic doses of 

 quinine, also camphor. 



PY-ffiMIA. 



Define pyczmia. 



A traumatic infectious disease, due to the absorption of 

 pyogenic microorganisms into the circulation with multiple 

 or metastatic abscesses in different portions of the body. 



What bacteria are of interest in pyaemia ? 



Practically all those which are productive of septicsemia,. i 

 especially the streptococcus pyogenes and the staphylococcus 

 pyogenes aureus. 

 How do these bacteria enter the general circulation 9 



There is first the infected wound ; the microorganisms 

 multiply, may come in contact with a vein, the vein becomes 

 inflamed as the result (phlebitis), and a thrombus is formed 

 at this point ; this thrombus undergoes puriform softening,', 

 and a piece of it is swept away .into the general circulation, 

 this little piece of broken down thrombus now being termed 

 embolus, and since it contains bacteria it represents an 

 infected embolus ; this embolus is carried along by the blood 

 until it reaches a bloodvessel having a smaller diametej than 

 its own. Here the embolus stops ; the bacteria which it con- 

 tains now multiply and an abscess follows. In this manner 

 abscesses develop in the various portions of the body.
