The investigators aimed to identify body temperature trajectory classes based on core temperature changes during the first 12 hours post-surgery and to explore their relationship with postoperative acute kidney injury in patients undergoing valvular heart surgery.

acute kidney injury ≥ stage 2 according to the KDIGO criteria
According to the KDIGO criteria, postoperative acute kidney injury of stage 2 or higher was defined as a 100% increase in creatinine within the first seven days after surgery. The association between stage 2-3 acute kidney injury and postoperative body temperature trajectory classes was investigated.
Time frame: seven days after valvular heart surgery
non-recovery from acute kidney injury within 48
The association between postoperative body temperature trajectory classes and non-recovery from acute kidney injury was investigated at two time points: within 48 hours
Time frame: 72 hours after the onset of acute kidney injury
non-recovery from acute kidney injury within 72 hours
The association between postoperative body temperature trajectory classes and non-recovery from acute kidney injury was investigated at two time points: within 72 hours.
Time frame: 72 hours after the onset of acute kidney injury
