The 1865–67 treatment centred on the wound and its dressing. Lister sought
to destroy contaminating material already present, then maintain an
antiseptic barrier while tissue healed. His recipes and materials changed:
carbolised lint, pastes and gauze, protective layers, drains, ligatures,
hand and instrument washing, and wound irrigation all appeared in the
evolving system. “Antiseptic surgery” was therefore not a fixed recipe
handed down in 1867 (Lister 1867b;
Worboys).
Lister developed carbolic spray in the subsequent phase of the work because
he feared germs in atmospheric dust. Hand-pumped and later steam devices
enveloped the operative field, patient, and staff in phenol mist. The
apparatus required an operator and exposed the team to an irritating,
hazardous chemical. Lister abandoned the spray in 1887 as contact from
hands, dressings, instruments, and skin became more important in his
reasoning (Science Museum Group).
Successful performance depended on people who are easy to lose in a
surgeon-centred story. Dressers prepared and changed dressings, assistants
managed apparatus, nurses sustained ward routines, and patients underwent
repeated inspection and treatment. Lister's publications and later manuals
transmitted some of this work step by step, while visits, demonstrations,
and training conveyed skills that print could not fully standardise
(Worboys;
Jones et al.).
