The Open Body Closed: A Rationale for the Abandonment of Bloodletting, Based on Nineteenth-Century Swedish Medicine.

This article contains an analysis of the use and abandonment of bloodletting in Sweden 1820-1900. Close readings of over 8,000 yearly reports by Swedish provincial doctors and popular medical handbooks, journals and notes from medical societies have been used, as well as key word searches meant to illustrate overarching tendencies. One result is that quantitative balance between humours was not an aim of therapeutic bleeding in this context. Rather, bloodletting was mainly used to reinstate regular flows in a hydraulic model of the body. It is argued that a shift from focusing on smooth flows to seeing bleeding as blood loss marked a transformation of the medical imagination from working with an 'open', malleable body to a 'closed', fixed body. This helps explain why therapeutic bleeding, for millennia the most important practice in medical practitioners' arsenal, was silently abandoned decades before the breakthrough of bacteriology and scientific medicine.
