Analysis Of Cerebral Hemodynamic Changes In Coma Patients With Viral Encephalitis

Objective:To explore the relevance of GCS and TCD parameters and discovered the better TCD parameter which can assessment the disease timely and objective, as well as appraises patient's prognosis.in the early time, by observing the cerebral hemodynamic situation during the course of Encephalitis virus patients with coma,Learn the cerebral hemodynamic during the process of unconscious patients.Method:Dynamic observation of cerebral blood flow of MCA in 12 cases of viral encephalitis patients admitted to the first day,third third day and seventh day, Record the TCD parameters and the GCS score simultaneously.Results:PI value and GCS score was significantly negatively correlated (r =- 0.72), Two cases of twelve have appeared eddy current signal, the frequency window of filling, and finally all died. Patients in coma for about three days a higher mortality rate, the latter stabilized.Conclusion:PI value of TCD can reflect the patient's condition to guide clinical treatment has definitely helped. According to several consecutive PI values and the spectrum , we Can know the initial condition development trends of the disease and determine prognosis.
