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 χ2 test.
† P values obtained by t-test.
‡ P value obtained by Mann-Whitney U test.
§ P value was calculated by χ2 test among three age groups.
IV, intravenous infusion; SD, standard deviation; TBSA, total burn surface area.
