  1. 1. Cardiopulmonary bypass: Clinical studies in cardiac surgery patients

    Författare :Mikael Barbu; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiopulmonary bypass; Cardiac surgery; Colloid; Prime; Acute kidney injury; Brain injury marker; Hemostasis;

    Sammanfattning : BACKGROUND: Cardiopulmonary bypass (CPB) is necessary to facilitate most cardiac operations. Although the vast majority of patients tolerate CPB physiology in conjunction with cardiac surgery well, there is risks of adverse outcomes. Optimal CPB perfusion is not defined, and may vary according to operation and patient specific factors. LÄS MER

  3. 2. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies

    Författare :Tor Damén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; blood pressure; hypotension; norepinephrine; haematocrit; plasma volume; atrial natriuretic peptide; glycocalyx; platelet aggregation;

    Sammanfattning : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). LÄS MER

  5. 4. Physiological and morphological aspects of the glomerular barrier in health and disease. Results based on experimental studies in the rat

    Författare :Clara Hjalmarsson; Göteborgs universitet; []
    Nyckelord :glomerular permeability; isolated perfused kidney; charge; endothelial surface layer; glycocalyx; electron microscopy; orosomucoid; nephrotic syndrome; proteinuria;

    Sammanfattning : Tremendous amounts of fluid are filtered every day through the kidneys. The anastomosing capillary loops surrounded by Bowman s capsule, forming the glomerulus, function in accordance with the interplay between the hydrostatic and the colloid osmotic pressure. The result of the action of these mechanisms is the production of primary urine. LÄS MER
