Non-invasive Monitoring and Serum Marker Study in Children With Cerebral Edema

Study Overview
=================
Brief Summary
-----------------
Purpose of the study：This study aimed to evaluate the clinical significance of serum SUR1, TRPM4 and MMP-9 in the diagnosis of cerebral edema in children with cerebral edema admitted to PICU by comparing them with CT results and perturbation coefficients, so as to provide biological indicators for clinical diagnosis of cerebral edema and provide targets for the treatment of cerebral edema in various diseases.

Detailed Description
-----------------
Early and efficient use of various measures to control and monitor peripheral cerebral edema and intracranial pressure, timely and accurate adjustment of treatment plan to reduce the degree of cerebral edema and reduce intracranial pressure, can significantly improve the development of the disease and prognosis recovery. At present, the clinical diagnosis of cerebral edema is mainly through clinical manifestations and imaging examinations, and there is a lack of corresponding biological examination methods.Purpose of the study：1.By analyzing the correlation between serum SUR1, TRPM4, MMP-9 and the electromagnetic disturbance coefficient, cranial CT results, Glasgow coma score, S100-β, NSE and prognostic score at 3 months of discharge, the clinical value of serum SUR1, TRPM4, MMP-9 and perturbation coefficient in the diagnosis, intracranial pressure monitoring, condition assessment and prognosis judgment of cerebral edema in children was explored.2.By analyzing the changes of the above indicators in various children with cerebral edema admitted to PICU, the types of cerebral edema and the cellular and molecular mechanisms of cerebral edema caused by different diseases were explored.
