Abstract
Aim:
To describe and compare temperature trends observed during continuous renal replacement therapy (CRRT) among patients receiving different warming approaches in routine clinical practice.
Methods:
Prospective observational study. Eighty-nine adult patients undergoing CRRT were assigned to one of three warming approaches. Core body temperature was recorded hourly for 8 h.
Results:
Mean body temperature decreased slightly over the 8-h period overall. Both active warming strategies maintained significantly higher temperatures compared to no warming. After adjustment for baseline temperature covariate, warming method remained a significant independent predictor of mean body temperature. The extracorporeal blood warming unit demonstrated the highest adjusted mean temperature and the greatest thermal stability over time. In contrast, the control group showed a progressive decline in temperature.
Conclusions:
Active warming strategies significantly improve thermal stability during CRRT, independent of baseline temperature. Extracorporeal blood warming appears superior to passive warming methods. These findings support routine integration of active warming devices into CRRT protocols to prevent hypothermia.
