Few reports in the literature describe the transfusion support needed for implantation and explantation of cardiac assist devices. Because such devices are frequently used at this institution, we have established a protocol to support these patients. We reviewed blood bank records to document the usage of blood components in all patients on cardiac assist devices from 1989 to 2005 (n = 215). The data were separated into components given at the time of implantation and explantation of the device. Implantation data on 214 patients showed the mean use as follows: red blood cells (RBC), 5.7 U; platelets (PLT), 2.4 U; fresh frozen plasma (FFP), 7.5 U; and cryoprecipitate, 0 U. Explantation data on 134 patients showed a mean use as follows: RBC, 7.7 U; PLT, 2.4 U; FFP, 9.9 U; and cryoprecipitate, 3.7 U. Our protocol for the preparation of blood components for implantation and explantation of a cardiac device is, implantation: RBC, 4 U; PLT, 1 U; FFP, 6 U; explantation: RBC, 8 U; PLT, 2 U; FFP, 8 U. Our data do not support the need for preparation of cryoprecipitate before implantation or explantation.
文献中很少有报告描述心脏辅助装置植入和取出时所需的输血支持。由于该机构经常使用此类装置，我们制定了一项方案来支持这些患者。我们查阅了血库记录，以记录1989年至2005年期间所有使用心脏辅助装置患者的血液成分使用情况（n = 215）。数据分为装置植入和取出时给予的成分。214例患者的植入数据显示平均使用量如下：红细胞（RBC），5.7单位；血小板（PLT），2.4单位；新鲜冰冻血浆（FFP），7.5单位；冷沉淀，0单位。134例患者的取出数据显示平均使用量如下：RBC，7.7单位；PLT，2.4单位；FFP，9.9单位；冷沉淀，3.7单位。我们关于心脏装置植入和取出时血液成分准备的方案是，植入：RBC，4单位；PLT，1单位；FFP，6单位；取出：RBC，8单位；PLT，2单位；FFP，8单位。我们的数据不支持在植入或取出前准备冷沉淀的必要性。
