  1. 1. Splanchnic circulation in cardiac surgery

    Författare :Michael Gårdebäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cardiopulmonary bypass dopamine dopexamine echocardiography ethanol; heart surgery indocyanine green intramucosal pHi splanchnic circulationMichael Gårdebäck; 1996;

    Sammanfattning : The studies addressed different techniques of monitoring hepatic and splanchnic blood flow (SBF) during open heart surgery. Calculations of gastric mucosal pH (pHi) using tonometry was performed in 72 patients, and the effect of dopaminergic stimulation on pH1 was studied in 33 patients. LÄS MER

  3. 2. Splanchnic perfusion in cardiac surgery

    Författare :Anders Thorén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

    Sammanfattning : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. LÄS MER

  4. 3. Monitoring of Splanchnic Regional Perfusion : An Experimental Study of New Application and Validation

    Författare :Itaru Koga; Lennart Christiansson; Lars Wiklund; Björn Biber; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Splanchnic circulation; Regional ischemia; Hepatic artery buffer response; Air tonometry; Intraperitoneal; Reflectance pulse oximetry; Hepatic venous oxygen saturation; Lactate; PCO2 gap; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Sammanfattning : Systemic infection, major surgery, trauma and many other causes can lead to impaired organ function. Compensated shock is not detected by global hemodynamic and oxygen measurements, as they take no account for regional variations. LÄS MER

  5. 4. The gastrointestinal tract in cardiac anaesthesia and intensive care : Clinical and experimental studies

    Författare :Jenny Seilitz; Kristofer Nilsson; Kjell Jansson; Birger Axelsson; Måns Edström; Sten Rubertsson; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute Gastrointestinal Injury grade; biomarkers; extracorporeal circulation; splanchnic perfusion; inotropic drugs; vasoactive drugs; lactate; lactate pyruvate ratio;

    Sammanfattning : Gastrointestinal (GI) complications after cardiac surgery have a substantial impact on outcome. The aims were to investigate the frequency of, and methods for detecting, GI dysfunction after cardiac surgery and its relation to outcome, and the impact of vasoactive drugs on the GI tract in experimental cardiogenic shock.

  7. 5. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Författare :Johan Snygg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Sammanfattning : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.
