A fluid-warming pressure infusion device (H-500/H25i, Level 1) was modified to meet the demands for safe, normothermic, and effective massive transfusions. By incorporating an autoventing 40 microns filter (Pall AV-SP), which was originally manufactured for use in an extracorporal circulation, the risk of accidental air embolism can be eliminated. Feasibility and efficiency of this model were tested in ten patients. The mean volume transfused and infused (packed red cells and colloids) was 6750 mL (SD +/- 2519) during a mean period of acute volume resuscitation of 55 minutes (SD +/- 30). Calculated flow rates averaged 140 mL/min, which were sufficient to stabilize all but one patient. This patient subsequently died because of uncontrollable surgical bleeding. Body temperature remained stable with a minimal mean drop of -0.3 degrees C. Supplying the Level 1 warming and pressure device with a Pall AV-SP filter allows for safe, effective, and demand-adapted massive transfusions in a large number of trauma patients at a reasonable cost.
一种液体加热压力输注装置（H - 500/H25i，一级）经过改装，以满足安全、常温及有效大量输血的需求。通过并入一个最初为体外循环制造的自动排气40微米过滤器（颇尔AV - SP），可消除意外空气栓塞的风险。该型号的可行性和效率在10名患者身上进行了测试。在平均55分钟（标准差±30）的急性容量复苏期间，平均输注和注入的量（浓缩红细胞和胶体）为6750毫升（标准差±2519）。计算得出的流速平均为140毫升/分钟，除一名患者外，足以稳定所有患者的情况。该患者随后因手术出血无法控制而死亡。体温保持稳定，平均降幅最小为 - 0.3摄氏度。为一级加热和压力装置配备颇尔AV - SP过滤器，能够以合理成本为大量创伤患者进行安全、有效且按需调整的大量输血。
