  1. 1. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin

    Författare :Lena Lindholm; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; cardiac surgery; regional oxygenation; venous oxygenation; splanchnic oxygenation; insulin; vasodilation; temperature; pump flow;

    Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

    Sammanfattning : Background and aims: Lung recruitment maneuvers (brief episodes of high airway pressure) are a modern treatment alternative to achieve open lung conditions under mechanical ventilation of patients with acute lung injury. It is well known that positive pressure ventilation with high airway pressures cause negative circulatory effects, and that the effects on regional vascular beds can be even more pronounced than the systemic effects.

  5. 4. Tissue Perfusion and Oxygenation Evaluated by Measurements of Tissue Gases and pH. An Experiemental Study

    Författare :Åke Mellström; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Anestesiologi; intensivvård; Anaesthesiology; Tissue pH; Tissue PCO2; Oxygen utilization; Tissue PO2;

    Sammanfattning : Optimum peripheral perfusion, oxygenation and oxygen utilization is a prerequisite for normal wound healing, resistance to infection and cardiac function. The purpose of this study was to evaluate peripheral oxygen utilization by measurements of subcutaneous tissue gases and pH (PscO2, PscCO2 and pHsc) in comparison to established techniques for measurements of periph-eral tissue oxygenation and oxygen utilization in experimental animal models with hyperoxia-hypoxia, acidosis-alkalosis and haemorrhage-resuscitation.

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

    Författare :Andreas Nygren; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
