摘要目的 探讨两步法涡流水浴加温模式用于大量快速输血的可行性。方法 随机选取库存红细胞悬液血样,于水浴复温前、后采样,分别进行细菌定性培养、血气分析、游离血红蛋白(FHb)含量测定。为测试加温效能,水浴温度均设定为(37.5±0.5)℃,实验随机分四组:两步法涡流水浴加温组A( n =10),血袋涡流水浴加温组B( n =10),血袋静止水浴加温组C( n =10),输血器管路涡流水浴加温组D( n =10)。各组血样分别以10、20、30、40、50及60 mL/min的速度进行输注,记录血样的输出端温度。结果 血样复温前后的细菌学测定均为阴性;复温后各组血样的红细胞计数(RBC)、红细胞压积(HCT)、血清钾离子(K +)浓度及FHb含量与复温前比较差异无统计学意义( P >0.05);A组以10、20、30、40、50及60 mL/min的速度进行模拟输注,输出末温度(℃:35.0±0.2,34.1±0.1,33.4±0.2,33.1±0.2,33.0±0.2,32.7±0.2)均在32 ℃以上,明显高于B、C、D组( P <0.001)。结论 两步法涡流水浴加温模式具有安全、高效、便捷等特点,适用于临床大量、快速输血加温。
