Since the beginning of the 21st century, modern neurosurgery has undergone revolutionary changes from the concept and equipment. Despite this, there are still great differences in various fields of neurosurgery, especially in neurosurgery critical care medicine, and there are still differences in diagnosis and treatment standards from place to place. In the past 30 years, critical care medicine has made great progress, accumulated rich experience, and saved the lives of many patients with organ failure and even multi-system and multi-organ failure. It is the goal of future development to learn from the experience and ideas of the development of critical care medicine to do a good job in the critical disease of neurosurgery. In order to popularize relevant knowledge and concepts, standardize medical behavior and improve the level of critical care in neurosurgery, the Neurosurgery Branch of Chinese Medical Association gathered a number of experts in the discipline to discuss relevant discussions, and at the same time invited domestic experts in critical care medicine, neurology, emergency medicine and other specialties as consultants and guides to jointly formulate the Expert Consensus on Neurosurgery Critical Care Management (referred to as the Consensus). Neurosurgery critical care is not only an interdisciplinary subject of neurosurgery, critical care medicine, neurology, emergency medicine, critical care and other specialties, but also an important branch of critical care medicine. Specialized, precise, targeted and multidisciplinary collaborative treatment units are the future development direction of neurosurgical critical care medicine. This consensus is mainly applicable to the treatment of critically ill adult neurosurgical patients. In view of the relevant contents involved, this consensus, under the cooperation and guidance of the Center for Evidence-Based Medicine of Peking University, adopted the evidence criteria and recommendation criteria of Oxford Center for Evidence-Based Medicine for grading (seeTable 1)。
