  3. 2. On microvascular blood flow assessment with the new microdialysis urea clearance technique

    Författare :Simon Farnebo; Folke Sjöberg; Ola Collin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microdialysis; microcirculation; Plastic surgery; Plastikkirurgi;

    Sammanfattning : The aim of this thesis was to develop and evaluate a new way of monitoring blood flow with microdialysis. A thin catheter consisting of a semipermeable membrane is implanted in the tissue being studied. LÄS MER

  4. 3. Microdialysis : potentials and limitations

    Författare :Anna von Platen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Despite improvements in operating technique and post-operative management, many patients undergoing liver transplantation still suffer post-operative complications, which may lead to graft loss or patient death. Patients are monitored closely post-operatively using blood chemistry, diagnostic imaging and liver biopsies to detect these complications including rejection and arterial- and portal vein thrombosis.

    Författare :Joakim Bergman; Anders Svenningsson; A. Tommy Bergenheim; Jonathan D. Gilthorpe; Joachim Burman; Magnus Andersson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Progressive Multiple Sclerosis; intrathecal treatment; Ommaya reservoir; anti-CD20 therapy; microdialysis; cerebrospinal fluid; CNS compartments; Progressiv Multipel Skleros; intratekal behandling; Ommaya reservoar; anti-CD20 terapi; mikrodialys; ryggmärgsvätska; sektioner i centrala nervsystemet; Neurology; neurologi;

    Sammanfattning : Background: Multiple Sclerosis (MS) is a chronic, inflammatory, autoimmune disease, affecting the central nervous system (CNS). About 85% of afflicted present with a relapsing-remitting form of the disease (RRMS), for which a breakthrough in treatment was made in 2008 with rituximab, an antibody directed towards CD20, a surface antigen on B-cells.

  7. 5. 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
