Abstract: Intracranial hypertension remains the key biomarker of severe traumatic brain injury for neurosurgery doctors. The monitoring of intracranial pressure (ICP) provides the technical support of precision and effective treatment strategy. In this article, the authors analyze the methodology, timing, function and development trend of ICP monitoring. The developing process of ICP monitoring contains the efforts of exploring a safe and precise technique to reflect the pressure in an injured brain. The modern ICP monitoring technology provides sufficient information flow for the management of craniocerebral trauma. Neurosurgeons could follow the information in the value and trends of ICP monitoring and implement it into decision making throughout the whole process of patient management. With the advanced data collecting and analyzing system the clinician can look into the waveform and parameter generalized by ICP value, and can interpret to the pathophysiological profiling in brain. ICP monitoring could exert efficacy not only in reflecting the mechanism of brain injury but also in the directing the clinical practice.
