Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Targeted temperature management to 33°C
Treatment: Surgery - Standard care with early treatment of fever

Active comparator: Normothermia - Standard care with early treatment of fever. Active temperature control with a device will be used if the patient develops a temperature greater than or equal 37.8°C.

Experimental: Hypothermia - Targeted temperature management to 33°C for up to 28h.


Treatment: Surgery: Targeted temperature management to 33°C
Rapid cooling to below 33°C, followed by temperature control at 33°C for up to 28h.

Treatment: Surgery: Standard care with early treatment of fever
