Purpose: For the treat hypothermia patients, active warming might be needed. In most emergency departments, IV warm saline infusion is used for treatments. However, during IV warm saline infusion, heat loss from the warm saline may occur and aggravate hypothermia. Thus, in this study, we conducted an experiment on conserving heat loss from warm saline by using a simple method. Methods: Four insulation methods were used for this study. 1) wrapping the set tube for the administration of the IV fluid with a cotton bandage, 2) wrapping the set tube for the administration of the IV fluid with a cotton bandage with aluminum foil, 3) wrapping the warm saline bag and tube with a cotton bandage, and 4) wrapping the warm saline bag and tube with a cotton bandage with aluminum foil. Intravenous fluid was preheated to a temperature between $38-40^{\circ}C$. The temperatures of the saline bag temperature and the distal end of the IV administration set were measured every ten minutes for an hour. The infusion rate was 1000 cc/hr, and to obtain an accurate infusion rate, we used an infusion pump. Results: The mean initial temperature of the saline bag was $39.11^{\circ}C$. An hour later, the fluid temperature at the distal end of the fluid temperature ranged from $39.11^{\circ}C$ to $34.3^{\circ}C$. Without any insulation, the initial temperature of the pre-heated warm saline, $39^{\circ}$ had decreased to $34.8^{\circ}C$ after having been run through the 170-cm-long IV administration tube, and after 1-hour, the temperature was $29.63^{\circ}C$. As we expected, heat loss was prevented most by wrapping both the saline bag and the IV administration set with a cotton bandage and aluminum foil. Conclusion: Wrapping both the saline bag and the IV administration set with a cotton bandage and aluminum foil can prevent heat loss during IV infusion in Emergency departments.

문제 정의
Furthermore, we conducted another experiment which adjust the flow rate. The aim of this experiment was to reveal the relationship between the flow rate of the fluid and the heat loss of the fluid.
제안 방법
The aim of this study was to assess the effect of four different insulation techniques on heat loss occurring from IV fluid administration set tubing and the bag during infusion of warmed IV fluid at a rapid flow rate. We hypothesised that all four techniques would result in a significant decrease in heat loss.
대상 데이터
This study was performed during January 2013 and the area of the resuscitation room was 22.58 m2. At the time we performed this study, the ambient temperature of the room was 26.
성능/효과
Hypothermia occurs in a cold environment and often occurs in trauma patients(1) or perioperative patients.(2) In trauma patients, hypothermia, metabolic acidosis, and coagulopathy are a lethal triad of mortality, and hypothermia is an independent factor that increases mortality.(3) Trauma patients require large volumes of rapidly infused intravenous (IV) fluid,(4) therefore, hypothermia may develop quickly during transfer or in the emergency department (ED) if the patient is uncovered and undergoes rapid administration of fluids or blood.
Comparing control group and wrapping saline bag and IV administration set with cotton bandage and aluminium foil, heat loss of saline bag had significant statistically difference (p-value<0.05).
후속연구
So we cannot predict precisely when we resuscitate the patients in emergent situation. Furthermore, further study can be possible. First, as we discussed above, raising infusion rate may reduce heat loss of infused fluid.
