2. 1. Importance of renal function in cardiac surgery

   Author : Alain Dardashti; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute kidney injury; eGFR; Transfusion; Mortality; Erythropoietin; Cardiac surgery;

   Abstract : Abstract Acute kidney injury (AKI) is a common and serious complication after cardiothoracic surgery and is associated with increased short- and long-term mortality risk. Despite extensive studies in the field, a comprehensive understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and partly due to the limitations of available routine biomarkers to predict, prevent, and detect AKI.

4. 2. Lipid Micro Emboli in Cardiac Surgery

   Author : Atli Eyjolfsson; Thoraxkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : 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. READ MORE

5. 3. Fat contamination of pericardial suction blood in cardiac surgery : clinical and experimental studies in perspectives of transfusion logistics

   Author : Micael Appelblad; Gunnar Engström; Krister Lindmark; Anders Jeppsson; Umeå universitet; []
   Keywords : Surgery; blood transfusion; cardiopulmonary bypass; pericardial suction blood; fat contamination; lipid microemboli; density separation; surface adsorption; Kirurgi; Surgery; kirurgi;

   Abstract : Introduction: During cardiac surgery aided by cardiopulmonary bypass (CPB) the autotransfusion of pericardial suction blood (PSB) is regarded mandatory to limit allogeneic blood exposure. PSB is however proposed as a source of lipid microemboli and to contribute to brain damage. READ MORE

6. 4. Clinical Aspects of Bleeding and Transfusion in Cardiac Surgery

   Author : Lisa Ternström; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; bleeding; fibrinogen; blood transfusion; transfusion guidelines; adherence;

   Abstract : Abstract Excessive bleeding after cardiac surgery is a serious complication that is associated with increased morbidity and mortality. The bleeding is multifactorial and influenced by both surgical factors and impaired haemostasis. READ MORE

7. 5. Heparin coating and cardiotomy suction in cardiopulmonary bypass

   Author : Staffan Svenmarker; Torkel Åberg; Gunnar Engström; Thomas Karlsson; Jarle Vaage; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; cardiopulmonary bypass; oxygenators; heparin; S100 proteins; blood loss; haemostasis; memory; outcome and process assessment; Kirurgi; Surgery; Kirurgi; kirurgi; Surgery;

   Abstract : 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).
