We compared a simple method of warming stored blood by immersion of blood bags in warm water, to the standard method using portex blood warming infusion coils, which are not freely available in Sri Lanka. The mean temperature of blood after warming by immersion of blood bags was 29.5 degrees C and by infusion coil 30.2 degrees C. The values were within the confidence limits of each other. Ten units of blood in each group were compared with regard to changes in free haemoglobin (Hb), packed cell volume (PCV), and hydrogen ion concentration, and no statistically significant difference was observed. We recommend immersion warming as a safe and effective alternative to warming by infusion coil.
我们将一种通过把血袋浸入温水中来加热储存血液的简单方法，与使用Portex血液加温输注盘管的标准方法进行了比较，而这种盘管在斯里兰卡无法随意获取。通过浸入血袋加温后血液的平均温度为29.5摄氏度，通过输注盘管加温后的平均温度为30.2摄氏度。这些数值在彼此的置信区间内。对每组中的十单位血液在游离血红蛋白（Hb）、血细胞比容（PCV）和氢离子浓度的变化方面进行了比较，未观察到统计学上的显著差异。我们推荐浸入式加温作为一种安全有效的替代输注盘管加温的方法。
