The use of autologous blood techniques affords the reduction or elimination of homologous blood transfusions for most patients. In addition, for certain religious faiths such as Jehovah's Witnesses or those patients with rare blood types, intraoperative salvage and return of the patient's own blood is the only source of available blood. Autologous blood salvage in the perioperative period includes: hemodilution; intraoperative salvage of lost blood; postoperative collection of shed blood. Perioperatively, autologous blood is salvaged and returned and the volumes involved do not create any hematological problems for the patient. In those cases involving large volumes of blood being processed and returned to the patient, the autotransfusionist must be aware of the possible alterations that may occur in the patient's coagulation system. The collection and reinfusion of wound drainage fluids from operative sites has the potential to cause severe bleeding problems. This paper will present an overview of autologous blood salvage techniques in the perioperative period along with a review of the clinical effects of autotransfusion on hemostasis. Also discussed will be possible coagulopathies that can be caused by returning collected autologous blood.
自体血液技术的应用可减少或消除大多数患者的异体输血。此外，对于某些宗教信仰群体，如耶和华见证人，或那些血型罕见的患者，术中回收并回输患者自身的血液是唯一可用的血液来源。围手术期自体血液回收包括：血液稀释；术中失血回收；术后引流血收集。在围手术期，自体血液被回收并回输，且回输的血量不会给患者造成任何血液学问题。在那些涉及大量血液被处理并回输给患者的情况下，自体输血人员必须意识到患者凝血系统可能发生的变化。从手术部位收集并回输伤口引流液有可能导致严重的出血问题。本文将概述围手术期自体血液回收技术，并回顾自体输血对止血的临床效果。还将讨论回输收集的自体血液可能导致的凝血病。
