A crossover trial was conducted to compare hand rub and hand scrub-brush methods for reducing bacterial loads when using propan-1-ol-60% according to European regulations. Both methods significantly reduced the bacterial load immediately after antisepsis, but only the hand rub method achieved significant bacterial load reduction 3 hours after the procedure.

During the Great War, the French surgeon Alexis Carrel, in collaboration with the English chemist Henry Dakin, devised an antiseptic treatment for infected wounds. This paper focuses on Carrel’s attempt to standardise knowledge of infected wounds and their treatment, and looks closely at the vision of surgical skill he espoused and its difference from those associated with the doctrines of scientific management. Examining contemporary claims that the Carrel–Dakin method increased rather than diminished demands on surgical work, this paper further shows how debates about antiseptic wound treatment opened up a critical space for considering the nature of skill as a vital dynamic in surgical innovation and practice.

This paper examines the origins of aseptic surgery in the German-speaking countries. It interprets asepsis as the outcome of a mutual realignment of surgery and laboratory science. In that process, phenomena of surgical reality were being modelled and simplified in the bacteriological laboratory so that they could be subjected to control by the researcher’s hands and eyes. Once control was achieved, it was being extended to surgical practice by recreating the relevant features of the controlled laboratory environment in the surgical work place. This strategy can be seen in the adoption of Robert Koch’s bacteriology by German-speaking surgeons, and the resulting technical changes of surgery, leading to a set of beliefs and practices, which eventually came to be called ‘asepsis’.
