样本采集：脑脊液标本由临床医生进行腰椎穿刺采集，必要时可从小脑延脑池或侧脑室穿刺获得。采集的脑脊液应尽量避免凝固和混入血液。放液不宜过速、过多，放出少量脑脊液（1-2ml），做最必要的检查。腰穿后去枕平卧24小时，严密观察病情，经常注意生命体征和瞳孔的变化。如发现头痛剧烈、颈痛、精神委靡、瞳孔不等大、意识障碍加重等，则有发生脑疝的可能，应积极采取脱水、降颅压等措施。\\
标本运送：标本采集后要立即加盖送检，一般不能超过1小时。否则需加入氟化钠，若未加盖暴露于空气中的时间较 长，空气中许多杂菌可将脑脊液葡萄糖分解，使糖假性降低。因标本采集较难，全部送检过程应注意安全。

%%tab-注意事项
　　腰穿前应注意有无颅内压增高症状和体征，必要时做眼底检查。血小板减少性紫癜、血友病、急性白血病患者，腰穿要特别慎重，有时可并发脊髓硬膜下血肿。宜用小号穿剌针。\\
