  1. 1. Levosimendan in early experimental sepsis: effects on the heart and hepatosplanchnic circulation

    Författare :Doris Cunha Goncalves; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; septic shock; myocardial oxygen consumption; myocardial dysfunction; levosimendan; endotoxin; contractility; catecholamines; calcium sensitizer; cardiotonic agents; splanchnic perfusion;

    Sammanfattning : Sepsis-related cardiovascular dysfunction associated with fluid-unresponsive tissue hypoperfusion might require inotropic treatment. This cardiovascular dysfunction seems to involve calcium desensitization and adrenergic unresponsiveness. LÄS MER

  3. 2. Severe Hemodilution - Clinical and Experimental Studies

    Författare :Valéria Perez de Sá; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shivering; critical oxygen delivery; oxygen consumption; child; dextran; hypothermia; hemodilution; anemia; Anaesthesiology; intensive care; Anestesiologi; intensivvård; lactates;

    Sammanfattning : In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23 occasions in 19 children, 1-17 years of age, with healthy hearts and lungs.

  4. 3. Hemodynamic and cardiometabolic studies in patients with distributive circulatory dysfunctions : with special reference to the effects of the beta-1-adrenoreceptor agonist prenalterol

    Författare :Sebastian Reiz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic aneurysm surgery; gram negative septic shock; hemodynamics; myocardial metabolism; thermodilution; thoracic epidural block; volume loading; prenalterol;

    Sammanfattning : A total of 49 patients were studied, using invasive hemodynamic techniques with systemic arterial, pulmonary artery and right atrial pressure recordings together with thermodilution cardiac output determinations. Sixteen of the patients were also subjected to cardiometabolic studies, using measurement of coronary sinus blood flow by the continuous thermodilution technique and analyses of oxygen content and lactate concentration in the systemic and coronary circulation.

  5. 4. Diabetes and Coronary Surgery : Metabolic and clinical studies on diabetic patients after coronary surgery with special reference to cardiac metabolism and high-dose GIK

    Författare :Zoltán Szabó; Folke Nilsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; heart; coronary surgery; cardiac surgery; myocardial metabolism; free fatty; Thoracic surgery; Thoraxkirurgi;

    Sammanfattning : Introduction An increasing proportion of the patients undergoing cardiac surgery have diabetes mellitus, in particular type II diabetes. In spite of this, diabetic patients have received limited attention in this setting. LÄS MER

  7. 5. Cardiovascular response to hyperoxemia, hemodilution and burns : a clinical and experimental study

    Författare :Zoltan Bak; Birgitta Janerot Sjöberg; Robert Hahn; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; general; Burns; Echocardiography; transesophageal; Hemodilution; emodynamic processes; Hyperoxia; Intensive care; Intensivvård;

    Sammanfattning : The last decades less invasive monitoring and analytical tools have been developed for the evaluation of myocardial mechanics in clinical praxis. In critical care, these are longed-for complements to pulmonary artery catheter monitoring, additionally offering previously inaccessible information. LÄS MER
