  4. 4. Vasopressors and intestinal mucosal perfusion. Studies in cardiac surgical and critically ill patients

    University dissertation from Göteborg : Göteborg University

    Author : Andreas Nygren; Göteborgs universitet.; Gothenburg University.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : During trauma, surgery and critically illness, splanchnic ischemia and reperfusion damage maythreaten the barrier function of the intestinal mucosa, leading to bacterial translocation, immuneactivation and subsequent development of systemic inflammatory response syndrome. Detection,prevention and treatment of intestinal mucosal hypoperfusion are therefore important forprevention of complications in critically ill patients. READ MORE
