Objective To evaluate the condition of blood transfusion requirements during extracorporeal circulation ( ECC ) in patients underwent cardiovascular surgery. Methods The blood transfusion requirements during ECC of 9196 patients underwent cardiac surgery between August 2007 and July 2010 were retrospectively analyzed. Results Average requirements of packed red blood cell ( PRBC ) or fresh frozen plasma ( FFP ) during ECC were ( 167. 7 ± 187. 8 ) ml and ( 123. 9 ± 164. 1 ) ml; The blood requirements during ECC were affected by operations procedure, age and body weight of patient. There was a significantly higher PRBC requirement in female then that in male for adult patients. Residual ECC circuit blood volume was similar to requirement of blood during ECC. Conclusion Individualization or miniaturization of ECC circuit according to patients pre - operative conditions will reduce the need for blood transfusions during ECC.%目的 探讨体外循环(ECC)手术用血状况.方法 回顾性分析近三年9 196例ECC相关手术过程中血制品使用情况.结果 平均每例手术ECC过程中浓缩红细胞(PRBC)和新鲜冰冻血浆(FFP)用量分别为(167.7±187.8)ml和(123.9±164.1)ml;手术种类不同将明显影响血制品用量;患者年龄和体重对血制品用量有明显影响;成人病例中,女性患者红细胞用量显著高于男性患者;ECC残余血量与ECC血制品使用总量接近.结论 ECC装置的个体化或微型化是目前减少ECC术中血制品用量的重要方法.
