In this report, the authors suggest evidence-based approaches to minimize the chance of perioperative spinal cord injury (POSCI) and optimize outcome in the event of a POSCI.
A systematic review of the basic science and clinical literature is presented.
Authors of clinical studies have assessed intraoperative monitoring to minimize the chance of POSCI. Furthermore, preoperative factors and intraoperative issues that place patients at increased risk of POSCI have been identified, including developmental stenosis, ankylosing spondylitis, preexisting myelopathy, and severe deformity with spinal cord compromise. However, no studies have assessed methods to optimize outcomes specifically after POSCIs. There are a number of studies focussed on the pathophysiology of SCI and the minimization of secondary damage. These basic science and clinical studies are reviewed, and treatment options outlined in this article.
There are a number of treatment options, including maintenance of mean arterial blood pressure > 80 mm Hg, starting methylprednisolone treatment preoperatively, and multimodality monitoring to help prevent POSCI occurrence, minimize secondary damage, and potentially improve the clinical outcome of after a POSCI. Further prospective cohort studies are needed to delineate incidence rate, current practice patterns for preventing injury and minimizing the clinical consequences of POSCI, factors that may increase the risk of POSCI, and determinants of clinical outcome in the event of a POSCI.
在本报告中,作者提出基于证据的方法,以尽量减少围手术期脊髓损伤(POSCI)的发生几率,并在发生POSCI时优化治疗结果。
对基础科学和临床文献进行系统综述。
临床研究的作者评估了术中监测,以尽量减少POSCI的发生几率。此外,已确定使患者发生POSCI风险增加的术前因素和术中问题,包括发育性椎管狭窄、强直性脊柱炎、既往存在的脊髓病以及伴有脊髓受压的严重畸形。然而,尚无研究评估在发生POSCI后具体优化治疗结果的方法。有许多研究关注脊髓损伤的病理生理学以及继发性损伤的最小化。本文对这些基础科学和临床研究进行了综述,并概述了治疗选择。
有多种治疗选择,包括维持平均动脉血压>80 mmHg、术前开始甲基强的松龙治疗以及多模式监测,以帮助预防POSCI的发生、减少继发性损伤,并可能改善POSCI后的临床结果。需要进一步的前瞻性队列研究来确定发病率、预防损伤和最小化POSCI临床后果的当前实践模式、可能增加POSCI风险的因素以及发生POSCI时临床结果的决定因素。
