    Abstract : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

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

    Author : Andreas Nygren; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : ;

    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

    Abstract : Introduction: To reduce the risk for pressure ulcers, repositioning of immobile patients is an important standard nursing practice. However, knowledge on how this preventive intervention is carried out among elderly immobile patients is limited and to what extent patients perform minor movements between nursing staff-induced repositionings is largely unknown, but these movements might have implications for the repositioning intervention.
