PYEMIA AND SEPTICEMIA. 



Multiplicity of Septicsemias. Pyaemia and Septicaemia, distinction 

 between. Multiple secondary abscesses in pyaemia ; no secondary abscesses 

 in uncomplicated septicaemia. Septico-pyaemia. Pyesmia. Causes : bac- 

 teria, deep wound infection, susceptibility, debility, shock, illness, narcotic 

 ptomaines, partial immunization, complexity of infection, mutual decom- 

 position of toxins, dose, lesions of intima of blood vessels, thrombosis, 

 embolism, action of microbes on haematoblasts and blood globules, viscidity 

 of cells, adhesion to endothelium, coagula, solution of clot, escape of 

 microbes. Lesions : wound, abscess, thrombus, emboli, infarction, abscesses, 

 ulceration, endocarditis. Spleen. Blood coagulates. Symptoms : rigor, 

 hyperthermia with remissions, pulse weak, soft, rapid, perspiration, diar- 

 rhoea, sweet breath, faeces, urine acid, dulness, prostration, mucosae dusky 

 or yellow, blood shows leucocytosis, haemolysis, cardiac murmur, arthritis, 

 stupor, coma, palsy, dry, puffy sore, source of infection. Prognosis grave. 

 Prevention : largely surgical, antisepsis, asepsis, excision of infected vein. 

 Treatment : antiseptics, locally and internally, stimulants, tonics, nourish- 

 ment. Septicemia : microbes, toxins, septic intoxication, septic infection, 

 fermentation fever, sapraemic fever. Lesions : blood dark, incoagulable, 

 spleen enlarged — gorged, petechiae, cloudy swellings, coagulation necrosis, 

 organs as if parboiled, congested glands, kidneys. Symptoms : chill slight, 

 hyperthermia without marked remissions, weak, rapid pulse, hurried 

 breathing; anorexia, emesis, yellow mucosae, nervous disorder — dulness, 

 apathy, stupor, paraplegia. Value of precursory conditions. Prognosis 

 grave. Prevention, Treatment : remove source of poison, antiseptics, drain- 

 age, internal antisepsis, strychnia, quinine, iron chloride, stimulants, sup- 

 porting, easily digestible food, sponging. 



At first introduced to indicate the supposed results of pus and 

 septic material respectively in the blood, these terms have come 

 to represent the clinical phenomena which come from the intro- 

 duction into a susceptible system of pyogenic and necrogenic 

 microbes and their toxic products. Gradually different affections, 

 which would have been included under the same general terms, 

 came to be identified under specific names, and a number of these 

 will be described as individual diseases— strangles, mouse and
