BACKGROUND
Transfusions of refrigerator-temperature blood, particularly when given very quickly, may induce severe hypothermia. In Germany, blood warmers used to avoid this danger mainly operate with dry heat.
MATERIAL AND METHODS
In the current study we compared the Fenwal BW-5 (Travenol), the Biotest BW 385 and BW 385L (Biegler) and the DW 1220 (American Pharmaseal) at different flow rates of packed cells and Ringer Lactate solution, respectively.
RESULTS
Up to flow rates of about 30 ml/min higher transfusion temperatures were reached by the Biotest BW 385L than by other warmers. Above flow rates of about 60 up to about 100 ml/min only the Fenwal BW-5 reached a transfusion temperature higher than 30 degrees C.
CONCLUSIONS
For routine transfusions and infusions the Biotest BW 385L is the most suitable warmer. If a massive transfusion is necessary, it is recommendable to use two or three Fenwal BW-5 or to apply other technologies.
背景
输注冷藏血液，尤其是快速输注时，可能会导致严重体温过低。在德国，用于避免这种危险的血液加温器主要采用干热方式运行。
材料与方法
在本研究中，我们分别比较了Fenwal BW - 5（Travenol）、Biotest BW 385和BW 385L（Biegler）以及DW 1220（American Pharmaseal）在不同红细胞悬液和乳酸林格氏液流速下的性能。
结果
在流速高达约30毫升/分钟时，Biotest BW 385L达到的输血温度高于其他加温器。在流速约60至约100毫升/分钟以上时，只有Fenwal BW - 5达到高于30摄氏度的输血温度。
结论
对于常规输血和输液，Biotest BW 385L是最合适的加温器。如果需要大量输血，建议使用两个或三个Fenwal BW - 5或采用其他技术。
