  1. 6. 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%.

  3. 7. Microcirculation in tissue repair - from microsurgery to 3D bioprinting

    Författare :Matteo Amoroso; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microsurgery; 3D bioprinting;

    Sammanfattning : Microsurgical reconstruction is challenged by two main shortcomings: Perfusion Related Complication (PRC) and donor site morbidity. In the first 3 studies of this thesis, we aimed to provide solutions to PRC-problems, investigating hemodilution as a tool able to increase blood flow in flap microcirculation. LÄS MER

  4. 8. Cardiopulmonary bypass and the kidney - studies on patients undergoing cardiac surgery

    Författare :Lukas Lannemyr; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; cardiopulmonary bypass; glomerular filtration rate; renal blood flow; renal oxygenation; tubular injury; N-acetyl-ß-D-glucoseaminidase;

    Sammanfattning : Acute kidney injury is a common complication after cardiac surgery with cardiopulmonary bypass (CPB), and has a major impact on morbidity, mortality and costs. The mechanism of CPB-related renal impairment is not fully understood. LÄS MER

  5. 9. Clinical Bedside Studies of Cerebral Blood Flow in Severe Subarachnoid Hemorrhage Using Xenon CT

    Författare :Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; delayed cerebral ischemia; cerebral blood flow; HHH-therapy; triple-H; xenon CT; XeCT; cerebral microdialysis; Neurokirurgi; Neurosurgery;

    Sammanfattning : Aneurysmal subarachnoid hemorrhage (SAH) is frequently complicated by delayed cerebral ischemia (DCI), contributing to poor outcome. Particularly for patients in poor neurological state, prediction of the acute clinical course is difficult, as is the early detection of DCI. LÄS MER

  7. 10. The use of fibrinogen in cardiac surgery patients-clinical and experimental studies

    Författare :Katarina Waldén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fibrinogen; cardiac surgery; bleeding; transfusion; thromboembolism; tranexamic acid;

    Sammanfattning : BACKGROUND Cardiac surgery with cardiopulmonary bypass impairs hemostasis due to hemodilution and consumption of platelets and coagulation factors, such as fibrinogen. The aim of this thesis was to study the role of fibrinogen in bleeding complications in cardiac surgery patients. LÄS MER
