ABSTRACT
Objective To investigate the clinical features and characteristics of imaging,cerebral hemodynamics and electrophysiology of septic encephalopathy in children.Methods The clinical data and examination result of computerized tomography(CT),ultrasound and electroencephalogram(EEG) on encephalon of the 44 consecutive children with septic encephalopathy from Jan.2003 to Jun.2006 were reviewed retrospectively.According to the prognosis and the etiology,the totally 44 patients were divided into survival group,death group and pneumonia group,enteritis group,septicemia group,appendicular perforation group,skin gangrene group as well as EBV infection group,respectively.Fi-sher′s exact test was used to compare the differences of ratio.Results 1.Clinical manifestations:loss of consciousness was observed in all 44 cases,convulsions in 29 cases,upper-right-limb paralysis in 1 case,cerebral hernia in 1 case,and 14 cases resulted in death.2.Forteen cases were detected by CT scanning.Multiple local and diffuse lower density in cerebral parenchyma was observed in 3 cases and 2 cases respectively.Intracranial hemorrhage was found in the latter 2 cases.3.Color doppler ultrasound was detected in 11 cases.Diffuse brain edema was found in 5 cases,and among them intracranial hemorrhage was found in 1 case.4.EEG was detected in 10 cases.Flat-to-isoelectric EEG was found in 3 cases.Diffuse slow wave activities and sharp wave with sharp-slow wave complex were found in 5 cases and 2 cases,respectively.5.Between the sharp wave group and the flat-to-isoelectric EEG group,the number of cases who was less than 7 with Glasgow coma scale was significant(P
