Conditions

Outcome Measures

Primary Outcomes (2)

  • Cerebral oxygenation during surgery

    Oxygenation of the brain is measured by near-infrared spectroscopy and by evaluation of the brain tissue oxygen pressure by two microelectrodes placed in the brain.

    During surgery

  • Cerebral blood flow during surgery

    Thermal diffusion flowmetry measures the local absolute cerebral blood flow

    During surgery

Secondary Outcomes (3)

  • Electrophysiological changes in the brain during surgery

    During surgery

  • Effect of ventilation with 100 % oxygen on cerebral parameters after rapid ventricular pacing

    Intraoperative ( Start of ventilation at 100% oxygen until bloodgas analyses shows an increase in arterial oxygen pressure.)

  • Effect of hyperventilation on cerebral parameters after rapid ventricular pacing

    Intraoperative (Start of hyperventilation until bloodgas analyses shows an arterial carbon dioxide pressure between 24 and 32 millimetre of mercury.)
