ABSTRACT
Pediatric intensive care unit(PICU) is the last guarantee for children whose lives were threatened.Brain injury are accompanied in many patients,in which ones dying or surviving were associated with whether their cerebral function would be recovered.Closely monitoring the brain function,especially the metabolic balance of cerebral oxygenation to detect cerebral hypoperfusion and low oxygen delivery and timely interventions being introduced can reduce mortality and longterm sequela.Current trends in monitoring cerebral oxygenation are poor in PICUs of our country.It is very helpful in evaluating cerebral function and predicting prognosis from learning characteristics of cerebral oxygenic balance and monitoring methods of cerebral oxygenation.At present,monitoring cerebral oxygen includes intracranial pressure,cerebral perfusion pressure,jugular venous oxygen saturation,brain tissue oxygen tension,cerebral blood flow,and near infrared spectrum technology and so on.
