Clinical Trial Summary

Neurocritical care is a major branch in the field of critical care medicine, and more than 50% of the neurocritical care patients in the Tibet Autonomous Region People's Hospital (TARPH) are in neurocritical care, of which cranial damage accounts for about 30%, and paroxysmal sympathetic hyperexcitability syndrome (PSH) after traumatic brain injury（TBI）is a common complication, which affects the cardiorespiratory and cerebral functions to varying degrees, and optimizing the cerebral perfusion and oxygenation supply is the key point in the treatment of TIB, and the maintenance of the cerebral homeostasis and the functional homeostasis is currently an international hotspot for treatment. Maintaining cerebral homeostasis and body function homeostasis is an international hotspot in the treatment of TIB. This study intends to elaborate on the relationship between PSH and Intracranial blood flow in patients with TBI, as well as the effect of anti-stress treatment on Intracranial blood flow. Implementation Patients with brain injury admitted to our department from January 2021 to January 2022 were included. Non-invasive transcranial Doppler ultrasound was applied to measure cerebral blood flow, non-invasive local cerebral oxygen saturation monitor to measure local cerebral oxygen saturation, and an electroencephalography bispectrometer to measure BIS score to quantify the depth of sedation during the experimental process. Bedside ultrasound monitored the right heart function and lung water status, and the data of each monitoring index were monitored and recorded throughout the whole process, and the relationship between concomitant PSH and Intracranial blood flow in TBI patients was found according to the statistical analysis. Ultimately, to achieve the control of TBI complications and improve patient rescue. To expect to achieve the purpose of improving the prognosis of TBI patients.
