    Sammanfattning : 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. LÄS MER

  3. 2. Exploring Intestinal Ischemia : An experimental study

    Författare :Rolf Fröjse; Conny Arnerlöv; Ola Winsö; Stefan Lehtipalo; Eric Wahlberg; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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). LÄS MER

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

    Författare :Mikael Ljungdahl; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Splanchnic organ homeostasis in experimental endotoxin shock : with special reference to the endothelin and renin-angiotensin systems

    Författare :Anders Oldner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endotoxin; endothelin; angiotensin II shock; tonometry microdialysis; porcine; hypoxanthine; gut; splanchnic circulation; lactate; mucosal pHi;

    Sammanfattning : Splanchnic organ homeostasis may become severely deteriorated in states of sepsis and endotoxaemia. Gut tissue hypoxia with subsequent increases in intestinal mucosal permeability has been proposed to contribute to the development of multiple organ failure. LÄS MER

  7. 5. 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
