Review Meta Analysis
Efficacy of antifibrinolytic agents on surgical bleeding and transfusion requirements in spine surgery: a meta-analysis.
Spine surgery is usually associated with large amount of blood loss and blood transfusion. Excessive blood loss may cause hypotension, inadequate oxygenation of organs, necessitate allogeneic blood transfusion, and spinal epidural hematoma formation. Aprotinin, TXA, and EACA are antifibrinolytics currently offered as prophylactic agents to reduce surgery-associated blood loss. The purpose of this study was to assess the efficacy of using antifibrinolytic agents in reducing blood loss and blood transfusions in spine surgery. ⋯ The antifibrinolytic agents were able to reduce perioperative blood loss and transfusion requirements in spine surgery. TXA appeared more effective than aprotinin and EACA in reducing total blood loss, intra-operative blood loss, and blood transfusion according to the results of this analysis. The three groups in reducing the post-operative blood loss are significantly better than control groups. There was no evidence that the use of antifibrinolytic agents was a risk factor for thromboembolism in spine surgery. Further multicenter, large-sample, double-blind RCTs are required to confirm the efficacy and safety of the three antifibrinolytic agents in spine surgery.

Review Meta Analysis
Laminectomy and fusion vs laminoplasty for multi-level cervical myelopathy: a systematic review and meta-analysis.
Surgical approaches for multi-level cervical spondylotic myelopathy (CSM) include posterior cervical surgery via laminectomy and fusion (LF) or expansive laminoplasty (EL). The relative benefits and risks of either approach in terms of clinical outcomes and complications are not well established. A systematic review and meta-analysis was conducted to address this topic. ⋯ From the available low-quality evidence, LF and EL approaches for CSM demonstrates similar clinical improvement and loss of lordosis. However, a higher complication rate was found in LF group, including significantly higher nerve palsy complications. This requires further validation and investigation in larger sample-size prospective and randomized studies.
