  1. 1. Extreme hemodilution: Effects of inhalation anesthetics, hypoxia, and blood loss. An Experimental study in pigs

    Författare :Henning Schou; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; oxygen saturation.; blood volume; coronary circulation; blood lactate; oxygen uptake; Anemia; oxygen delivery; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : Hemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%.

  4. 3. Intrarenal oxygen homeostasis in acute and chronic kidney disease

    Författare :Oskar Nensén; Fredrik Palm; Börje Haraldsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; acute kidney injury; oxygen; kidney disease; renal physiology; Fysiologi; Physiology;

    Sammanfattning : Renal hypoxia has been recognized as a common feature of acute and chronic kidney injury arising from varying etiologies. It has also been proposed to provide a driving mechanism for the transition from acute to chronic kidney disease (CKD). LÄS MER

  5. 4. The Role of Kidney Oxygen Homeostasis for the Development of Kidney Disease

    Författare :Carla Carvalho; Fredrik Palm; Peter Hansell; Malou Friederich; Jenny Nyström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxygen; Kidney mitochondria; Hypoxia-inducible factors; Prolyl hydroxylase; von Hippel-Lindau; Diabetes; Aging; Kidney; Sodium; RAAS; Fysiologi; Physiology;

    Sammanfattning : The relation between oxygen supply and demand determines tissue oxygen tension (PO2). When intrarenal tissue PO2 decreases, any compensatory increase in oxygen supply via increased renal blood flow is likely to increase glomerular filtration rate. LÄS MER

  7. 5. Fibrinolysis and blood loss in major arthroplasty. The effect of tranexamic acid

    Författare :Göran Benoni; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; oxygen saturation.; blood loss; pharmacokinetics; tranexamic acid; Fibrinolysis; knee and hip arthroplasty; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Blood loss in major arthroplasty may be abundant and often necessitates blood transfusions. These may transmit disease and entail an immunological burden to the recipient. After trauma and surgery, the fibrinolytic system reacts with a short period of increased activity, followed by a fibrinolytic shut-down. LÄS MER
