小儿细菌性脑膜炎和病毒性脑膜炎的治疗和予后完全不同,故早期鉴定细菌性或病毒性甚为重要。以往普遍认为无菌性脑膜炎患儿脑脊液白细胞数<500/mm~3,Feigin等报告87％无菌性脑膜炎脑脊液中白细胞8小时内由以中性占优势变为单核占优势,且与病毒型别无关。作者报告1次肠道病毒71型引起无菌性脑膜炎的流行,脑脊液白细胞持续以中性占优势,偶而以淋巴占优势,测定脑脊液乳酸脱氢酶(LDH)证实病原仍属病毒性。本文收集纽约某医院1977年7月1日至1977年10 Pediatric bacterial meningitis and viral meningitis treatment and prognosis is completely different, so early identification of bacterial or viral is very important. In the past generally considered aseptic meningitis in children with cerebrospinal fluid white blood cell count <500 / mm ~ 3, Feigin and other reports of 87% of aseptic meningitis cerebrospinal fluid leukocytes within 8 hours from neutral predominance to mononuclear dominant, and Has nothing to do with the virus type. The authors report that a single enterovirus 71 epidemic caused aseptic meningitis. Leukocytes in the CSF continued to be predominantly neutral, occasionally predominantly lymphoid, and cerebrospinal fluid lactate dehydrogenase (LDH) was determined to be still viral. This article collects a New York hospital from July 1, 1977 to December 1977
