    • Acute heart failure syndromes : treatment, outcomes and pathophysiological aspects of inflammation and vascular function 

      Hermansen, Stig Eggen (Doctoral thesis; Doktorgradsavhandling, 2012-11-01)
      Akutt hjertesvikt, spesielt ved sirkulatorisk kollaps, er en dramatisk tilstand med høy dødelighet. Forekomsten av akutt hjertesvikt er økende og tilgjengelig kunnskap om sykdomsmekanismene samt medisinsk behandling er begrenset.De siste tiår har det vært en revolusjonerende utvikling i behandlingen av og overlevelsen ved iskemisk hjertesykdom og akutt hjerteinfarkt. Tilsvarende utvikling har det ...

    • Clinical guided computer tomography decisions are advocated in potentially severely injured trauma patients: a one-year audit in a level 1 trauma centre with long pre-hospital times 

      Bågenholm, Anna; Dehli, Trond; Hermansen, Stig Eggen; Bartnes, Kristian; Larsen, Marthe; Ingebrigtsen, Tor (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-10)
      <i>Background</i> - The International Commission on Radiological Protection’s (ICRP) justification principles state that an examination is justified if the potential benefit outweighs the risk for radiation harm. Computer tomography (CT) contributes 50% of the radiation dose from medical imaging, and in trauma patients, the use of standardized whole body CT (SWBCT) increases. Guidelines are lacking, ...

    • Cooling to hypothermic circulatory arrest by immersion vs. cardiopulmonary bypass (CPB): Worse outcome after rewarming in immersion cooled pigs 

      Filseth, Ole Magnus; Hermansen, Stig Eggen; Kondratyev, Timofey; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-31)
      Introduction: Cooling by cardiopulmonary bypass (CPB) to deep hypothermic cardiac arrest (HCA) for cardiac surgical interventions, followed by CPB-rewarming is performed on a routine basis with relatively low mortality. In contrast, victims of deep accidental hypothermia rewarmed with CPB generally have a much worse prognosis. Thus, we have developed an intact pig model to compare effects on ...

    • Direct angiography demonstrates equal 8-12 years patency rates of radial artery and saphenous vein grafts 

      Bahar, Ramez; Dahl-Eriksen, Øystein; Busund, Rolf; Dahl, Per Erling; Hermansen, Stig Eggen; Iqbal, Amjid; Mannsverk, Jan; Myrmel, Truls; Steigen, Terje; Trovik, Thor; Sørlie, Dag Glen; Bartnes, Kristian (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-30)
      Objectives: The benefits of coronary artery bypass surgery depend on lasting graft patency. To aid rational graft selection, the relative long-term merits of radial artery and saphenous vein grafts need to be determined by a gold standard method and with minimal clinically driven selection bias. Methods: The patency rates of various conduits were determined by direct angiography in 76 patients from ...

    • Health-related quality of life after extracorporeal membrane oxygenation: a single centre's experience 

      Ørbo, Marte; Karlsen, Sidsel Fredheim; Pedersen, Ellinor Phillips; Hermansen, Stig Eggen; Rønning, Per Bjørnerud; Aas, Kathrine Nergård; Næsheim, Torvind; Myrmel, Truls (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-07)
      <i>Aims</i>: The aims of this study were to evaluate health-related quality of life (HRQL) among patients treated with extracorpo-real membrane oxygenation (ECMO) in northern Norway over a period of 27years (1988–2015) and to identify variables related to HRQL.<p> <p><i>Methods and results</i>: A retrospective inquiry of the ECMO registry at the University Hospital of North Norway identified 74 ...

    • The risk factors for radial artery and saphenous vein graft occlusion are different 

      Bahar, Ramez; Hermansen, Stig Eggen; Dahl-Eriksen, Øystein; Busund, Rolf; Dahl, Per Erling; Iqbal, Amjid; Mannsverk, Jan Torbjørn; Myrmel, Truls; Steigen, Terje; Trovik, Thor; Sørlie, Dag Glen; Bartnes, Kristian (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-02)
      Objectives. To determine risk factors for radial artery and saphenous vein graft occlusion during long-term follow-up after coronary artery bypass grafting (CABG). Methods: From a cohort of 119 patients who had received a radial artery graft, 76 – of whom 55 also had at least one saphenous vein graft – underwent a preplanned direct angiography and anthropometric, biochemical, and endothelial ...

    • Vasopressin impairs brain, heart and kidney perfusion: an experimental study in pigs after transient myocardial ischemia 

      Müller, Stig; How, Ole-Jakob; Hermansen, Stig Eggen; Stenberg, Thor Allan; Sager, Georg; Myrmel, Truls (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-02-21)
      Introduction: Arginine vasopressin (AVP) is increasingly used to restore mean arterial pressure (MAP) in low-pressure shock states unresponsive to conventional inotropes. This is potentially deleterious since AVP is also known to reduce cardiac output by increasing vascular resistance. The effects of AVP on blood flow to vital organs and cardiac performance in a circulation altered by cardiac ...
