\b[Seek and control the infective source, drain accessible collections, support failing organs, and recognise that established <pyaemia> had a very poor outlook before effective <antibiotics>.] The historical term commonly described severe systemic illness, often after a wound or operation, with recurrent rigors and secondary <abscesses>. Modern explanations include <bacteraemia>, an infected <thrombus> producing <septic embolism>, and <metastatic infection>. It is misleading to reduce the condition to an inert quantity of <pus> freely floating through the <blood>.

In the 1864 setting, examine the original wound and any painful swollen region for retained infected material, an undrained <abscess>, dead tissue or obstructed drainage. An accessible collection calls for surgical drainage; a superficially healed wound should not conceal an undrained deeper focus. Remove obvious sources of continuing contamination, provide careful dressings, cleanliness, ventilation, nursing and tolerable nourishment, and relieve <pain>. Period practice used <quinine> and alcoholic stimulants as supportive remedies. A surgical report covering July 1863 to October 1864 records these measures in the Royal Infirmary; its publication in 1865 documents the period rather than supplying an Oxford model answer.<Royal Infirmary surgical ward report (1863–1864)>[p. 111: wound cleanliness, local applications and quinine and stimulants in pyaemia]{ref} Such measures did not reliably sterilise the <blood> or inaccessible secondary <abscesses>. Neither repeated purging nor <bloodletting> has a sound role in an already depleted, seriously infected person. Later organised surgical <antisepsis> should not be presented as an established system available at this examination.

Current care treats the presentation as possible <sepsis> with disseminated infection. Assess <airway>, breathing, <circulation>, mental state and organ function urgently. Obtain appropriate <blood cultures> and source samples without delaying necessary <antibiotic> treatment; investigate the original wound and likely secondary sites. <Ultrasonography> or other imaging can locate a collection for drainage. Persistent <bacteraemia>, embolic manifestations or a new <heart murmur> should prompt assessment for <infective endocarditis>, often including <echocardiography>. Source control may require drainage, removal of infected material or <debridement>. Initial <antibiotics> are chosen for the likely source and resistance risks, then narrowed using microbiological evidence.

Provide <oxygen therapy> when needed and carefully reassessed <intravenous fluids>; persistent circulatory failure requires critical-care treatment rather than indiscriminate fluid loading. Monitor <urine> output, <renal function>, <blood pressure> and response to treatment. The modern prognosis depends on source, organ injury and speed and adequacy of treatment, so the historical description alone does not support a numerical prediction.<Suspected sepsis in people aged 16 or over by NICE>[NG253, recognition, source investigation and antibiotic, intravenous-fluid and oxygen recommendations]{ref}
