摘要
Abstract
Ultrasound can qualitatively and quantitatively monitor the changes of intracranial pressure through cerebral midline displacement,optic nerve sheath diameter,transcranial Doppler spectrum and the measurements.Transcranial Doppler or transcranial color Doppler can monitor the real-time characteristics of cerebral blood flow,and provide important information of cerebrovascular reactivity and the autoregulation of cerebral blood flow.Critical ultrasound,which can monitor the intracranial pressure and the autoregulation of cerebral blood flow,together with jugular venous oxygen saturation which reflects the cerebral metabolic activity,and continuous EEG which reflects the electrical and functional activity of brain,constitute the important contents of cerebral hemodynamic monitoring,which helps evaluate the cerebral hemodynamics accurately,guides therapy,and predicts the prognosis.关键词
