This review discusses some of the recent advances and current controversies in the acute clinical management of traumatic brain injury (TBI) and spinal cord injury (SCI).
Several key risk factors for adverse prognosis in TBI have been identified, including female sex. In the management of intracranial hypertension antibiotic impregnated intraventricular catheters have been found to reduce the risk for infection, and new studies have examined the roles of mannitol, hyperventilation, and hypothermia. Moderate hypothermia has also been found to improve outcome. Hyperoxia is now being explored as a treatment option for improving brain metabolism in TBI. That acute SCI continues to be a challenging diagnosis is supported by a recent study that showed that 9.1% of SCIs are missed initially. The diagnosis and management of spinal instability has been studied in different patient groups. In SCI without radiographic abnormality, the presence of normal magnetic resonance imaging findings was associated with a good prognosis. New studies in the field of early decompression and the prevention of thromboembolism in SCI have also been published. Guidelines for the management of acute SCI recommend methylprednisolone and GM-1 ganglioside only as options.
In neurotrauma some established treatments have been re-examined and their efficacy proven, whereas others that were once considered the standard of care in SCI, such as methylprednisolone, have been questioned. Large multicenter trials are needed to assess treatments such as early decompression in SCI and decompressive craniectomy in TBI. A truly effective neuroprotective therapy in neurotrauma remains elusive.
本综述探讨创伤性脑损伤(TBI)和脊髓损伤(SCI)急性临床管理方面的一些最新进展和当前争议。
已确定TBI预后不良的几个关键危险因素,包括女性性别。在颅内高压的管理中,已发现抗生素浸渍的脑室内导管可降低感染风险,并且新的研究已探讨了甘露醇、过度通气和低温的作用。还发现中度低温可改善预后。目前正在探索高氧作为改善TBI脑代谢的治疗选择。最近一项研究表明,9.1%的SCI最初被漏诊,这支持了急性SCI仍然是一个具有挑战性的诊断。已在不同患者群体中研究了脊柱不稳定的诊断和管理。在无影像学异常的SCI中,磁共振成像结果正常与良好预后相关。SCI早期减压和预防血栓栓塞领域也发表了新的研究。急性SCI管理指南仅推荐甲基强的松龙和GM-1神经节苷脂作为选择。
在神经创伤方面,一些既定的治疗方法已被重新审视并证明其疗效,而其他一些曾被视为SCI标准治疗方法的药物,如甲基强的松龙,已受到质疑。需要进行大型多中心试验来评估SCI早期减压和TBI减压颅骨切除术等治疗方法。在神经创伤中真正有效的神经保护疗法仍然难以捉摸。
