围手术期超声测量视神经鞘直径预测颅内压增高的研究进展

The research progress of ultrasonographic optic nerve sheath diameter during perioperative period for assessing intracranial pressure

背景 近年来，超声监测视神经鞘直径（optic nerve sheath diameter， ONSD）评估颅内压（intracranial pressure， ICP）技术因其快速、无创等优势逐渐被重视。 目的 讨论围手术期ONSD测量预测颅内压增高（intracranial hypertension，ICH）的应用，为临床提供理论及技术支持。 内容 总结近年来的研究进展，就ONSD与ICP的相关性、ONSD预测ICH的临界值和ONSD测量在围手术期的应用等进行综述。 趋向 ONSD监测作为无创、便捷、快速、准确的床旁监测手段，可以更加广泛地应用于围手术期ICP变化的监测。超声监测ONSD具有广阔的应用和研究前景。

Background Recently, the technique of ultrasound monitoring optic nerve sheath diameter （ONSD） has been paid more attention due to its rapid, non-invasive and other advantages. Objective Investigating the new application of ONSD monitoring to provide the theoretical and technical support. Content We reviewed recent progresses in researches on correlations between ONSD and intracranial pressure（ICP）, critical value of ONSD and the application of ONSD measurement in perioperative period. Trend As a noninvasive, convenient, rapid and accurate bedside monitoring method, ONSD monitoring can be widely used for monitoring ICP changes during perioperative period. Ultrasound detection of ONSD bears a broad prospect of applications and researches.
