Spinal metastases occur in up to 70% of all patients with cancer. However, only 10% are symptomatic. Before considering central neuraxial blockade in patients with malignancy, a history of back pain should be excluded. Anaesthetists should be aware that intrathecal and epidural injections could cause paraplegia if metastases are impinging on the spinal cord. Failure to achieve adequate sensory anaesthesia after central neuraxial blockade or presentation with postoperative paraplegia may indicate the presence of asymptomatic vertebral canal metastases. In this report, the anaesthetic management of a patient with respiratory failure and spinal metastases from a soft tissue sarcoma, requiring caesarean section is described. Sensory anaesthesia extending above a level of imminent cord compression was achieved despite loss of cerebrospinal fluid signal on magnetic resonance imaging.
脊柱转移发生于所有癌症患者的比例高达 70%。然而,仅有 10%的患者有症状。在考虑对恶性肿瘤患者行中枢性神经轴阻滞前,应排除背痛病史。麻醉师应知晓,如果转移压迫脊髓,鞘内和硬膜外注射可能导致截瘫。如果中枢性神经轴阻滞后未能获得充分的感觉麻醉,或出现术后截瘫,可能提示存在无症状的椎管转移。在本报告中,我们描述了 1 例因呼吸衰竭和软组织肉瘤脊柱转移而需要剖宫产的患者的麻醉管理。尽管磁共振成像显示脑脊液信号缺失,但仍实现了超过即将发生脊髓压迫水平的感觉麻醉。
