菌血症病人意识混浊疑及脑膜炎时可行脑脊液检查.然而腰穿本身可使菌血症含菌的血液进入蛛网膜下腔造成细菌性脑膜炎.动物试验证明,在菌血症期间脑膜的创伤能促使细菌进入脑脊液.患有肺炎球菌菌血症的狗在脑池穿刺后能发生脑膜炎.以上情况均提示菌血症的患者在腰穿后能产生相似后果.作者既往曾遇到二例菌血症期间腰穿而致脑膜炎者,近分析了近20个月1089例血培养阳性者,仅200例在血培养三日内进行过腰穿.其中30人(15%)
Bacteremia patients with suspicion of suspicion of meningitis and cerebrospinal fluid may be feasible. However, lumbar puncture itself can make bacteremia bacteremia blood into the subarachnoid space caused by bacterial meningitis. Animal experiments show that during the period of bacteremia meninges Trauma can promote bacteria into the cerebrospinal fluid.Pacific pneumococcal bacteremia dogs in the brain pool can occur after puncture meningitis.All the above are prompted to bacteremia in patients with lumbar puncture can have similar consequences.The author has encountered two Cases of meningitis during lumbar puncture caused by meningitis, the recent analysis of 1089 blood culture positive in the past 20 months, only 200 cases of blood culture within three days had lumbar puncture, of which 30 (15%)
