[LEVEL 1--a new blood warming device].
Abstract
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.
