      <i>Background</i> - In different models of hypoxia, blockade of opioid or N-methyl-D-aspartate (NMDA) receptors shows cardio- and neuroprotective effects with a consequent increase in animal survival. The aim of the study was to investigate effects of pre-treatment with Morphine or Ketamine on hemodynamic, acid-base status, early survival, and biochemical markers of brain damage in a rat model of ...

    • Resistance to ventricular fibrillation predicted by the QRS/QTc - ratio in an intact rat model of hypothermia/rewarming 

      Dietrichs, Erik Sveberg; Selli, Anders Lund; Kondratiev, Timofei; McGlynn, Karen; Smith, Godfrey L; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-04)
      Accidental hypothermia is associated with increased risk for arrhythmias. QRS/QTc is proposed as an ECG-marker, where decreasing values predict hypothermia-induced ventricular arrhythmias. If reliable it should also predict nonappearance of arrhythmias, observed in species like rat that regularly tolerate prolonged hypothermia.<p> <p>A rat model designed for studying cardiovascular function during ...
