Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Routine Thermal Management | Patients assigned to routine thermal management will not be pre-warmed and ambient intraoperative temperature will be maintained near 20°C per routine. Only transfused blood will be warmed. An Multi-Position Upper Body Warming Blanket forced-air cover will be positioned over an appropriate non-operative site, but will not initially be activated. Should core temperature decrease to 35.5°C, the warmer will be activated as necessary to prevent core temperature from decreasing further.~routine thermal management: A forced-air cover will be positioned but will not initially be activated. The warmer will be activated when core temperature decrease to 35.5°C. | 24 | 2,506 | EG000 |
| Group 2 | Aggressive Thermal Management | Patients assigned to aggressive warming will be pre-warmed with a full-body Bair Hugger or Bair Paws cover for ≈30 minutes before induction of anesthesia. The warmer will initially be set to high which corresponds to ≈43°C. It will be subsequently adjusted to make patients feel warm, but not uncomfortably so. Patients will be aggressively warmed during surgery to a target intraoperative core temperature between 37 and 37.5°C, using an Multi-Position Upper Body and Full Access Underbody Warming Blankets forced-air covers when clinically practical. All intravenous fluids will be warmed to body temperature.~aggressive warming: Patients will be pre-warming 30 minutes before induction of anesthesia and aggressively warmed during surgery to a target intraoperative core temperature between 37 and 37.5°C. | 18 | 2,507 | EG001 |
