近红外光谱技术在颅脑损伤监护中的临床应用

Clinical Application of Near-Infrared Spectroscopy (NIRS) in Neurocritical Care of Patients with Brain Injury

继发性颅脑损伤引发的水肿、缺血、血管痉挛等会引起颅内压升高、脑血流量下降,最终导致脑组织缺氧以及不良预后,积极有效的脑氧饱和度监测有助于降低病死率及改善预后。近红外光谱技术是一项能够无创实时反映脑组织氧合的新兴技术,利用近红外光原理反映出脑组织氧供和氧耗平衡信息。本文就近红外光谱技术在颅脑损伤患者中的研究进展进行综述。

Cerebral edema, ischemia and vasospasm caused by secondary brain injury can lead to increased intracranial pressure and decreased cerebral blood flow, leading to cerebral tissue hypoxia and poor prognosis. Active and effective cerebral oxygen saturation monitoring can help reduce the mortality rate and improve prognosis. Near-infrared spectroscopy is an emerging technology that can reflect the oxygenation of brain tissues non-invasively and continuously, reflecting the balance of oxygen supply and oxygen consumption in brain tissues. This article reviews the progress of near-infrared spectroscopy in patients with brain injury.
