    Sammanfattning : The present thesis addresses various means of reducing inflammatory responses associated with cardiopulmonary bypass (CPB) and retransfusion of pericardial suction blood (PSB) during cardiac surgery. Four (I-IV) prospective randomised controlled clinical trials comprising 475 patients were performed in the following areas: effects of heparin coating on measures of clinical outcome and memory function (I, II), inflammatory reactions in PSB and its systemic effects after retransfusion using cardiotomy suction or cell salvage (III) and effects of retransfusion of PSB on memory function and release patterns of protein S100B (IV).

    Sammanfattning : The use of cardiotomy suction during open heart surgery with cardiopulmonary bypass (CPB) has a long tradition and often regarded as mandatory. Recently, studies have described potentially negative effects of cardiotomy suction with activation of the complement system, enhanced inflammatory response, hemolysis and coagulopathy. LÄS MER

  3. 3. Systemic inflammatory activation during cardiac Surgery. Influence of cardiopulmonary bypass management and patient factors

    Författare :Martin Westerberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :cardiopulmonary bypass; inflammatory response; coagulation; CABG; cardiotomy suction; cytokines;

    Sammanfattning : Cardiac surgery with cardiopulmonary bypass is accompanied by a prominent systemic inflammatory and hemostatic activation, which may contribute to postoperative complications. Aims: To investigate if selection of cardiopulmonary bypass (CPB) system and management of cardiotomy suction (CTS) and mediastinal shed blood (MSB) affect systemic inflammatory response. LÄS MER

  4. 4. S100B and Cardiac Surgery

    Sammanfattning : The brain-derived protein S100B is a 21 Kda dimerand have been used as a serum marker for brain damage of different etiology. The feasability of protein S100B as serum marker for brain damage after cardiac surgery was studied in this thesis. One unexpected finding was made, which changed the basis for interpration of S100B levels. LÄS MER

  5. 5. Lipid Micro Emboli in Cardiac Surgery

    Författare :Atli Eyjolfsson; Thoraxkirurgi; []

    Sammanfattning : This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. LÄS MER
