SEPSIS (Gr. Qi7,/iss, putrefaction), or SEPTIC INFECTION  , a See also:term applied in See also:medicine and See also:surgery to indicate the resultant infection of a See also:wound or sore by micro-organisms or by their products . Under this See also:general heading come three See also:great constitutional diseases, differing radically from each other in their See also:aetiology and See also:pathology: sapraemia, septicaemia and pyaemia . Sapraemia (Gr. vasrpbs, rotten, a ,ua, See also:blood), or septic See also:intoxication, is the result of the absorption of a dose of the toxins produced by micro-organisms from some See also:area of infection without the entrance of the micro-organisms themselves into the blood . This See also:condition was for a See also:long See also:time confounded with septicaemia, but is distinguished from it in being a chemical intoxication . The blood in sapraemia if injected into an See also:animal is incapableof reproducing the disease as in septicaemia . Any condition in which there is a See also:mass of decomposing See also:tissue in the See also:neighbour-See also:hood of an unhealed wound may give rise to sapraemia . In surgical practice it may be met with in large, deep and badly-drained wounds where a quantity of putrifying material is pent up . When it arises in connexion with wounds accidentally received, it may be unavoidably due to the dirty See also:state of the skin or to See also:foreign bodies entering the wound . Absorption of toxins is notably frequent in portions of decomposing placental tissue which may accidentally have remained behind in the uterus after childbirth, and may give rise to puerperal sapraemia . Sapraemia is acute or subacute directly according to the amount of toxin absorbed . By some writers it is divided as follows: (I) Hectic See also:fever is a chronic blood poisoning with continual absorption of small doses of the toxins . This variety usually arises in long-continued suppuration of bones and See also:joints, and in decomposition occurring in a pulmonary cavity .

The marked symptom is a See also:

sharp rise of temperature in the evenings; the See also:face becomes flushed and the See also:pulse rapid . After profuse sweating the temperature drops . See also:Diarrhoea and wasting are a usual See also:accompaniment . (2) Septic traumatic fever is a slight See also:form which may follow See also:burns or See also:compound fractures and which tends to subside in a few days . (3) In acute septic intoxication large amounts of the See also:poison are absorbed . It generally starts with a severe rigor followed by a continuous high temperature, dry See also:tongue, rapid pulse and severe headache, together with See also:nausea and vomiting, and in the later stages diarrhoea . If the See also:case be a severe one rapid prostration speedily comes on with See also:low muttering See also:delirium, the temperature may fall to subnormal, and a gradually deepening See also:coma may end in See also:death; other cases pass into a typically " typhoid state," death occurring from exhaustion at the end of about a See also:week . (4) Amyloid (Gr . (tµukov, See also:starch, abets, form), or lardaceous disease, usually of the See also:liver, See also:spleen, kidneys or other See also:organs, is one of the results of long-continued septic intoxication . A substance derived from the breaking down of pus and tissue cells is carried in the blood and deposited in the connective tissue of the coats of the smaller See also:arteries, and the viscera become infiltrated with a material looking like See also:lard . The liver and spleen, being the organs most usually affected, become immensely enlarged . No form of septic infection yields so easily to treatment as sapraemia .

The prompt removal of the cause of septic absorption, the See also:

flushing out of the wound with weak antiseptic solutions, in See also:order to mechanically remove any decomposing masses, and the See also:establishment of proper drainage in deep wounds, is usually followed by a fall in temperature and an improvement in the general condition . A strong, preferably See also:mercurial, purgative should be given to aid in the elimination of toxic material . For the same purpose the injection into the See also:veins or into the cellular tissue of large quantities of normal saline See also:solution is useful . See also:Heart depression should be overcome by diffusible stimulants and hypodermic injections of See also:strychnine . When the wound has become " surgically clean " recovery is usually rapid . Septicaemia is an acute infective disease differing from sapraemia in that the micro-organisms themselves are absorbed, entering the general circulation, and may on examination be found in greater or lesser number in the blood-stream itself . The organism or organisms grow and reproduce themselves in the blood or tissues . A number of different organisms have been isolated from the blood-stream in cases of septicaemia . The most frequently found is the Streptococcus pyogenes, which is See also:present in 50% of the cases and is See also:common in puerperal septicaemia and in ulcerative endocarditis . The Staphylococcus pyogenes aureus et albus is also a frequent cause, but sometimes septicaemia may be due to other pathogenic microbes such as the Pneumococcus, the Bacillus coli communis, Bacillus pyocyaneus, Bacillus oedematis maligni and the Gonococcus . The micro-organisms are conveyed by the blood-stream to different parts of the See also:body, in which as in the See also:original wound itself they both multiply and set up factories for the See also:production of toxins . The disease commonly follows blows or wounds which have not been treated on surgical lines .

Much laceration of the tissues at the time of the injury offers increased liability to infection . Septicaemia is frequent in spreading See also:

gangrene, in diseases of the periosteum, and in fevers such as scarlatina, See also:diphtheria or See also:plague, and in the puerperal state . The See also:period of See also:incubation may be from a few See also:hours to several days . The condition of the wound or site of injury shows marked changes . In severe cases following a prick received in conducting a See also:post-mortem the See also:finger in a few hours becomes greatly swollen and painful, the See also:pain spreading up the lymphatic vessels to the nearest lymphatic glands, which may become enlarged, and sloughing or gangrene of the parts involved may take See also:place . In milder cases the wound remains with reddened and oedematous margins in a more or less unhealthy state . In mild cases of septicaemia the See also:local condition of the wound, high temperature and feeling of illness are the distinguishing features . The treatment of septicaemia may be preventive or active . The preventive See also:side consists in the performance of operations with all due aseptic pre-cautions . Since the days when I . P . See also:Semmelweiss (q.v.) of See also:Vienna insisted on cleanliness in his maternity wards, the death-See also:rate of puerperal septicaemia has been enormously reduced .

In the See also:

British registrar-general's returns for 1868 it was stated that in twenty-two years no less than 23,689 See also:women in See also:England and See also:Wales had died of puerperal septic diseases . In the reports of the Rotunda See also:Hospital, See also:Dublin, the largest maternity hospital in the See also:United See also:Kingdom, we ascertain that of 30,023 women delivered during the ten years 1894–1903 there was only a mortality of 21 due to See also:sepsis, a ratio of o•o66%, while the registrar-general's returns for England and See also:Ireland for the period have a ratio for sepsis of x.216% . When dealing with a wound that is already septic, See also:free incision and swabbing the See also:surface with pure carbolic See also:acid may have to be resorted to, and constitutional treatment must be under-taken at once . Should the infection be due to a Streptococcus, an antistreptococcic serum may be injected . There are, however, many strains of Streptococci, and a polyvalent serum may give See also:good results . Menzer's antistreptococcic serum has been successful in puerperal septicaemia not of gonococcic origin . Many cases have also now been recorded in which the systemic infection is combated by means of an autogenous vaccine . The first case was described by See also:Sir See also:James See also:Barr before the Liver-See also:pool Medical See also:Institute in May 1906 . In urgent cases, where time will not allow of the manufacture of a vaccine, See also:quinine in large doses, stimulants and liquid nourishment must be given, and the temperature controlled by tepid sponging . Pyaemia (Gr. v6ov, pus, aiµa, blood), which got its name from an erroneous See also:idea that the pus passed into the blood, is now understood to mean an acute disease with the formation of metastatic abscesses . The first definite See also:account of the disease was published by See also:Boerhaave in 1720 . See also:Virchow in 1846 pointed out that it was not pus in the veins, but altered blood-See also:clot .

See also:

Jean D'Arcet showed the See also:separate processes of poisoning by products of decomposition and the blocking of the veins with emboli . Any pyogenic organism may give rise to pyaemia, or it may follow any acute See also:abscess . The cause of pyaemia may be said to be any condition favouring the formation of emboli . An occasional cause of pyaemia is infective endocarditis, while puerperal pyaemia may arise from infection of the genital See also:tract . When the emboli See also:lodge in the See also:lung there is a breaking down of the tissue in front of the embolus, a haemorrhagic infarct being formed . The clinical symptoms of acute pyaemia generally start with a rigor repeated at periodic intervals; the skin becomes hot and the patient soon develops an earthy See also:colour, the pulse becomes frequent and weak and the tongue dry . In about a week secondary abscesses appear, most frequently in the region of joints . There may be little or no pain to See also:herald the formation of an abscess, but usually there is intense pain followed by suppuration . Unless See also:early treatment is undertaken the See also:joint may be rapidly destroyed . In acute cases multiple abscesses in the See also:kidney may give rise to pain and See also:albuminuria, abscesses in the lungs to dyspnoea, while acute See also:peritonitis may arise from rupture of a splenic abscess into the peritoneal cavity,and sudden See also:blindness be the result of the plugging of the arteria centralis retinae . The duration of a case of pyaemia depends on the severity of the infection . Death may occur from the formation of abscesses in vital organs such as the See also:brain and heart, or from exhaustion from continued suppuration, or chronic forms may after months pass on to See also:complete recovery .

Unfortunately pyaemia cannot be recognized apart from other blood infections until abscesses begin to form . The local treatment is to endeavour to prevent the detachment of infected emboli and the infection of the general blood-stream thereby . An infected See also:

limb may be dealt with by' amputation above the seat of the See also:lesion, or it may be feasible to dissect out the infected veins . When abscesses have formed they must be dealt with by opening and washing out the cavities . Antistreptococcic serum may be tried, as in septicaemia; and if there be time to prepare a vaccine it offers the best prospects, more particularly in the subacute and chronic forms of pyaemia . The usual See also:administration of nourishing See also:diet and stimulants when required should be undertaken, and every effort made to keep up the patient's strength .
