Effect of Multimodal Monitoring Cluster Management on Patients with Severe Traumatic Brain Injury

All patients will be monitored for baseline TCD at admission and at least once a day during treatment to assess changes in cerebral blood flow dynamics. Brain Oxygen Monitoring, Equipment \& Frequency: Continuous monitoring of partial pressure of oxygen (PbtO2) in brain tissue using near-infrared spectroscopy (NIRS). qEEG monitoring，Frequency and timing of monitoring. Baseline monitoring: All patients will undergo a baseline qEEG test at the time of admission. Continuous monitoring: In the ICU, for critically ill patients, qEEG will be performed continuously to monitor changes in EEG activity in real time. Monitoring brain activity: qEEG is able to detect subtle changes in brain waves that can be used to assess brain functional status, such as EEG quiescence, abnormal electrical discharges (e.g., epileptiform activity), etc. Abnormal parameters: focus on abnormal rhythms (e.g., high-amplitude slow-wave activity), acute asymmetric activity, and epileptiform discharge.
