Outcome Measures

Primary Outcomes (1)

  • To detect changes in clotting time in seconds (s), during the first 3 days after target temperature (34 °C) is reached.

    Clotting time will be measured by thromboelastometry on the ROTEM-analyzer using a low-tissue-factor assay.

    22, 46 and 70 hours after target temperature (34 °C) is reached (+/- 2 hours).

Secondary Outcomes (4)

  • To detect changes in the clot formation time (s), during the first 3 days after target temperature (34 °C) is reached.

    22, 46 and 70 hours after target temperature (34 °C) is reached (+/- 2 hours).

  • To detect changes in maximum clot firmness (mm), during the first 3 days after target temperature (34 °C) is reached.

    22, 46 and 70 hours after hypothermia is reached. (+/- 2 hours)

  • To detect changes in time to maximum velocity (s), during the first 3 days after target temperature (34 °C) is reached.

    22, 46 and 70 hours after target temperature (34 °C) is reached (+/- 2 hours).

  • To detect changes in maximum velocity (mm/min.), during the first 3 days after target temperature (34 °C) is reached.

    22, 46 and 70 hours after target temperature (34 °C) is reached (+/- 2 hours).
