  2. 1. The small intestine in experimental peritonitis : An experimental study focusing om intestinal energy metabolism, bacterial translocation and mucosal immunology

    Author : Mikael Ljungdahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bacterial translocation; endotoxin; faecal peritonitis; high-energy phosphates; hypoxia; intramucosal pH; IL-6; ischaemia; lactate; lymphocytes; mucosal injury; oxygendelivery; pigs; sepsis; tonometry; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : The gut is highly susceptible to injury during sepsis. An impaired mucosal barrier permitstranslocation of enteric microorganisms to blood or other organs. In a porcine model sepsiswas induced by faecal peritonitis. READ MORE

  4. 2. On intestinal ischaemia after aortoiliac surgery : Epidemiological, clinical and experimental studies

    Author : Martin Björck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischaemia; intestines; colon; ischaemic colitis; aorta-abdominal; aortic aneurysm-abdominal; aortic rupture; atherosclerosis; postoperative complications; cohort studies; case-control studies; clinical protocols; experimental design; incidence; risk factors; diagnosis; treatment outcome; intra-mucosal pH; pHi; swine; splanchnic circulation; haemodynamics; dobutamine; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : An important cause of death among patients undergoing surgery of the abdominal aorta is intestinal ischaemia. In the Swedish Vascular Registry 2930 aortoiliac operations were identified. The complication was studied in a combined cohort and case-control study, and multivariate analysis performed. The incidence of intestinal ischaemia was 2. READ MORE

  5. 3. Splanchnic circulation in cardiac surgery

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

    Abstract : 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. READ MORE

  6. 4. Exploring Intestinal Ischemia : An experimental study

    Author : Rolf Fröjse; Conny Arnerlöv; Ola Winsö; Stefan Lehtipalo; Eric Wahlberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; gastrointestinal tonometry; continuous; pig; pHi; intestinal ischemia; intestinal vascular bed; lactate; tissue oxygen tension; microdialysis; dopexamine; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Background and aims: Unrecognized intestinal mucosal ischemia in severely ill patients may trigger development of multiple organ failure. Such ischemia can be evaluated by intraluminal tonometry reflecting mucosal PCO2 and intramucosal pH (pHi). READ MORE

  7. 5. Liver transplantation in man. Gastrointestinal perfusion and inflammatory response

    Author : Ebbe Rønholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbondioxide; complement activation; cytokines; endotoxaemia; hydrogen-ion concentration; liver transplantation; laser-Doppler flowmetry; PMN elastase; regional blood flow; reperfusion;

    Abstract : Patients undergoing liver transplantation develop a systemic inflammatory response which eventually continues with development of a multiple organ dysfunction syndrome (MODS). Gastro-intestinal hypoxia or bacterial translocation has been proposed as the "motor" of MODS. READ MORE
