对任何发热,可能为脑膜炎者应作腰椎穿刺(腰穿)。如果发现脑脊髓液(CSF)正常,临床医师常不愿再作穿刺。但正常结果可能误诊而排除脑膜炎。本文3例和文献报道7例患者的起始CSF中,蛋白、葡萄糖和细胞计数正常或极轻度异常,虽革兰氏染色涂片中无细菌,但培养均产生致病菌。患者年龄为4个月至76岁,以往均未经抗菌素治疗。3例的CSF完全正常,即白细胞计数少于5/立方毫米,蛋白低于45毫克/分升,葡萄
For any fever, meningitis may be used for lumbar puncture (lumbar puncture). If CSF is found to be normal, clinicians are often reluctant to puncture. However, normal results may be misdiagnosed and exclude meningitis. In this paper, 3 cases and 7 cases of patients reported in the beginning of the CSF protein, glucose and cell count normal or very mild abnormalities, although Gram stain smear without bacteria, but the culture has produced pathogenic bacteria. Patients ranged in age from 4 months to 76 years and had not been previously treated with antibiotics. The CSF of 3 patients was completely normal, that is, the white blood cell count was less than 5 / mm3, the protein was less than 45 mg / dL,
