腰椎后路椎间融合术是治疗腰椎间盘突出症、腰椎管狭窄、腰椎滑脱等腰椎退行性疾病常见术式之一，该术式学习曲线短、减压彻底、融合率较高、疗效确切，是脊柱外科常见术式之一。但手术创伤大，术中及术后失血量大且输血率高，尤其多节段融合术，术后常伴有不同程度的贫血，导致患者住院时间及康复时间延长。随着围手术血液管理的发展及一系列措施的提出，本文就腰椎后路椎间融合术围手术期血液管理综述如下。“,”Posterior lumbar interbody fusion is one of the common surgical procedures for the treatment of lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis and other lumbar degenerative diseases. It has the advantages of short learning curve, complete decompression, high fusion rate and exact curative effect. It is one of the common surgical procedures in spine surgery. However, the operation is traumatic, the blood loss during and after the operation is large, and the blood transfusion rate is high, especially in the multi-stage fusion operation, which is often accompanied with different degrees of anemia, leading to the prolongation of hospital stay and rehabilitation time. With the development of perioperative blood management and a series of measures, the perioperative blood management of lumbar posterior lumbar interbody fusion is summarized as follows.
