Data are presented as n ((%) or mean±SD.

The active warming in this text is to specifically use the patient warming system (WarmTouch).

P values in bold are considered statistically significant.

* P values obtained by χ

^{2}test.† P values obtained by t-test.

‡ P value obtained by Mann-Whitney U test.

§ P value was calculated by χ

^{2}test among three age groups.IV, intravenous infusion; SD, standard deviation; TBSA, total burn surface area.
