This paper begins with the lived accounts of emergency and critical care medical interventions in which an unhoused person is brought to the emergency department in cardiac arrest. The case is a dramatised representation of the extent to which biopolitical forces via reduction to bare life through biopolitical and necropolitical operations are prominent influences in nursing and medical care. This paper draws on the scholarship of Michel Foucault, Giorgio Agamben, and Achille Mbembe to offer a theoretical analysis of the power (...) dynamics that influence the health care and death care of patients who are caught in the auspices of a neoliberal capitalist healthcare apparatus. This paper offers analysis of the overt displays of biopower over those individuals cast aside as generally unworthy of access to healthcare in a postcolonial capitalist system, in addition to the ways in which humans are reduced to ‘bare life’ in their dying days. We analyse this case study through Agamben's description of thanatopolitics, a ‘regime of death’, and the technologies that accompany the dying process, particularly in that of the homo sacer. Additionally, this paper illustrates the ways in which necropolitics and biopower are integral to understanding how the most advanced and expensive medical interventions make visible the political values of the healthcare system and how nurses and healthcare functions in these deathworlds. The purpose of this paper is to develop a greater understanding of biopolitical and necropolitical operations in acute and critical care environments, and to offer guidance to nurses in these spaces as they work to uphold ethical duties in a system that increasingly dehumanises.
