Abstract:
Objective To analyze the changes of WBC classification,sugar and protein in cerebro-spinal fluid(CSF)and pathogenic bacteria of neonatal purulent meningitis.Methods Thirty-one neonates with bacterial meningitis in our department of neonatology from June 201 1 to June 2013 were enrolled,and the clinical features,pathogenic bacteria,laboratory examination of CSF were analyzed.Results Fever (90.3%),convulsions(67.7%)and changed consciousness(58.1 %)were common clinical symptoms.The incidences of other nervous system abnormal signs such as gastrointestinal dysfunction(25.8%),abnormal breathing(16.1 %),cervical resistance(16.1 %),bulging fontanel(9.7%)were lower.The Gram -negative bacteria was more than Gram -positive in both blood and CSF culture.The escherichia coli was the most common bacteria,with positive rate of 38.1 %(8 /21 )in blood culture and 55.5%(5 /9)in CSF culture.The germiculture positive rate in CSF was lower than in blood culture (29.0% vs.67.7%).Polymorphonuclear leukocyte(PMN)[(79.61 ±12.06)%]was the most predominant cell of the leukocyte classification in CSF within 1 week in all cases,PMN was still predominant in 1 to 2 weeks in 7 cases,while only 2 cases in 2 to 3 weeks still dominated by PMN,PMN was not the predominant cell 3 weeks later.Conclusion In the typi-cal neonatal purulent meningitis,PMN was the predominant cell in CSF within the first week,but the propor-tion of monocyte gradually increased and was dominant later.Escherichia coli was a common bacteria caused by this disease.
