  2. 1. Mesentric hemodynamics and effects of angiotensin II during circulatory stress

    Author : Mats Laesser; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renin-angiontensin system; angiotensin II; intestines; hemodynamics; perfusion; hemorrhage; hypovolemia; endotoxemia;

    Abstract : Mesenteric hypoperfusion and ischemia is considered to be deleterious to the intestinal mucosal barrier function and it is suggested that the renin-angiotensin system plays a pivotal role in the regulation of mesenteric perfusion.The present thesis examines the effects of the specific AT1 receptor blocker candesartan on mesenteric hemodynamics during acute hypovolemia and endotoxinemia.

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

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

    Abstract : 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. 3. Carbon Dioxide Pneumoperitoneum - Hemodynamic Consequences and Thromboembolic Complications

    Author : Fredrik Lindberg; K G Ljungström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopic surgery; carbon dioxide pneumoperitoneum; hemodynamics; coagulation; fibrinolysis; thromboembolic complications; phlebography; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : The laparoscopic way of performing general surgical procedures was introduced all over the Western world in a few years around 1990. No previous scientific studies of the safety of this new way of performing general surgery had been undertaken. READ MORE

  6. 4. Mean systemic filling pressure - from Guyton to the ICU, and back again

    Author : Per Werner Möller; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mean systemic filling pressure; venous return; right atrial pressure; positive pressure ventilation; extracorporeal membrane oxygenation;

    Abstract : Introduction: Mean systemic filling pressure (MSFP) is the equilibrated vascular pressure at zero flow. Venous return (VR) driving pressure (VRdP) is the difference between MSFP and right atrial pressure (RAP). READ MORE

  7. 5. Systemic absorption of glycine solution and the TUR syndrome : clinical, pathophysiological and pharmacological aspects

    Author : Anders Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Irrigating fluid transurethral resection of the prostate; complications adverse effects pharmacokineticsglycine sorbitol mannitol hemodynamics physiology hyponatremia body fluids fluid balance ethyl alcohol breathanalysisStockholm 1996;

    Abstract : Transurethral resection of the prostate (TURP) requires the use of an irrigating fluid to remove blood and debris to visualise the operating area. Despite modern technique, unpredictable amoumts of irrigating fluid, which usually consists of glycme 1.5% in sterile water, enters the circulation during nearly every routine TURP. READ MORE
