Hypothermia; Anesthesia
Conditions
Brief summary
The aim of this study is to compare the underbody blanket and overbody blanket for forced air warming to maintain normothermia in pediatric patients undergoing cardiovascular interventions under general anesthesia.
Interventions
applying upper body blanket with forced-air blower set to 43℃
applying full underbody blanket with forced-air blower set to 43℃

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| hypothermia | intraoperative period (from the time when patient enters the operating room to the time when patient exits the operating room) | time weighted average out of normothernia (body temperature over 37.5℃ and under 36.5℃) in intraoperative period |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| hyperthermia | intraoperative period (from the time when patient enters the operating room to the time when patient exits the operating room) | body temperature recorded over 37.5℃ |
| thermal comfort scale | 15 minutes, 30 minutes, 45 minutes, 60 minutes after entering the post-anesthesia care unit | asking subjects about the thermal sensation on a seven-point scale from cold(-3) to hot (+3) |
| patient satifisfaction at post-anesthesia care unit | 15 minutes, 30 minutes, 45 minutes, 60 minutes after entering the post-anesthesia care unit | visual analog scale score for measuring the patient satisfaction after the surgery (0\ 10) |
| shivering score at post-anesthesia care unit | 15 minutes, 30 minutes, 45 minutes, 60 minutes after entering the post-anesthesia care unit | 4 grades of shivering score measured at post-anesthesia care unit |
| clinical outcomes after the surgery | 5 days after the surgery | postoperative complications during hospitalization |
