Hypothermia of less than 35 degrees C, which frequently occurs in connection with massive blood transfusion, is a serious problem in many patients, in particular in those with polytrauma. The restoration of normal body temperature is very important and requires the use of a rapidly-acting, efficient and safe blood warmer, which is able to work effectively at high flow-rates. The LEVEL 1 (Technologies, Rockland, MA) is such a new blood warmer and works as a heat-exchanger via an aluminium column. This system is highly effective. Six hundred ml of sodium chloride 0.9% are warmed from 4 to 35 degrees C within one minute. This device is quickly operational and has a low priming volume. The LEVEL 1 is the only device currently available which is able to warm blood sufficiently during a very rapid blood transfusion.
体温低于35摄氏度的低温症常与大量输血相关，这在许多患者中，尤其是多发伤患者中是一个严重问题。恢复正常体温非常重要，需要使用一种作用迅速、高效且安全的血液加温器，该加温器能够在高流速下有效工作。LEVEL 1（技术公司，马萨诸塞州罗克兰）就是这样一种新型血液加温器，它通过铝柱作为热交换器。该系统非常有效。600毫升0.9%的氯化钠溶液在一分钟内从4摄氏度升温至35摄氏度。该设备操作迅速且预充量低。LEVEL 1是目前唯一一种能够在非常快速的输血过程中充分加温血液的设备。
