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

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

    Abstract : 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.

  5. 13. Monocytes, Tissue Factor and Heparin-coated Surfaces : Clinical and Experimental Studies

    Author : Matilda Johnell; Agneta Siegbahn; Rolf Larsson; Jesper Swedenborg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; monocytes; tissue factor; heparin-coated surfaces; coagulation; inflammation; thrombin; cytokines; cardiopulmonary bypass; biocompatibility; migration; chemotaxis; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : Cardiopulmonary bypass (CPB) is associated with inflammatory response and activation of coagulation. Heparin coating of the CPB circuit is shown to improve the biocompatibility of the surface. The biological effects of a new heparin surface, the Corline Heparin Surface (CHS), prepared according to a new principle, have been studied. READ MORE

  6. 14. Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury

    Author : Björn Reinsfelt; Göteborgs universitet; []
    Keywords : Cardiac surgery; cerrebral dysfunction; cardiopulmonary bypass; anaesthetics; aortic valve replacement; transcranial Doppler; cerebraospinal fluid; blood-brain barrier;

    Abstract : Cardiac surgery and the brain - studies on cerebral blood flow autoregulation and mechanisms of cerebral injury Björn Reinsfelt Department of Anaesthesiology and Intensive Care, Institute of Clinical Sciences, The Sahlgrenska Academy, University of Gothenburg, Sweden Abstract Cerebral dysfunction (CD) occurs frequently after cardiac surgery with cardiopulmonary bypass (CPB). The main causes of CD are thought to be cerebral hypoperfusion, cerebral microembolisation , cerebral inflammation or disruption of the blood brain barrier (BBB). READ MORE

  7. 15. Splanchnic perfusion in cardiac surgery

    Author : Anders Thorén; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

    Abstract : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. READ MORE
