Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective, multicenter, observational, cohort trail is to explore the pattern of brain temperature-brain pressure association in acute brain injury and to clarify its predictive value for prognosis and neurological function 30 days after acute brain injury.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Temperature abnormalities have long been recognized as signs of disease. Brain temperature, as part of body temperature, reflects body temperature and brain metabolism during physiologic states. There is growing evidence that brain cell function is unequivocally temperature dependent and that brain temperature after brain injury cannot be reliably predicted by core body temperature. Brain temperature is therefore increasingly becoming an important alternative to brain pressure, enabling patients with a variety of brain injuries to benefit from continuous brain temperature monitoring. Meanwhile, the correlation between intracranial pressure, which is currently the most widely used indicator in clinical practice, and brain temperature in patients with acute brain injury remains unelucidated. Whether the correlation between brain temperature and intracranial pressure has certain patterns and rhythms that can indirectly reflect the brain function of patients under the condition of injury and have a predictive value for clinical outcomes is the main research objective of this study. It is hoped that the present study will explore the correlation between brain temperature and brain pressure and the pattern of the correlation, as well as its impact on clinical prognosis. It provides a more precise target for intervention to further improve the prognosis of patients with acute brain injury.
