摘要 目的 :建立血清中硝西泮 (nitrazepam ,NZP)测定方法 ,监测婴儿痉挛 (infantilespasms,IS)患儿血清硝西泮浓度 ,探讨硝西泮合适剂量方案。方法 :8例IS患儿 ,口服NZP ,应用高效液相色谱法 (HPLC)分离和测定NZP血清浓度。结果 :NZP在 2 0~ 1 2 0 0 μg·L-1 范围内线性关系良好 ,血清中NZP最低检测浓度为 5 μg·L-1 ,绝对回收率达 94 %以上 ,日内RSD <2 .8%,日间RSD <3.7%。适合于血清NZP浓度监测。在 0 .5mg·kg-1 ·d-1 ,bid ,po剂量方案下 ,8例IS患儿的稳态血药浓度 (谷浓度 )个体差异大 ,在 1 0 2 .8~36 1 .8μg·L-1 之间。结论 :本方法简便、快速、准确 ,适用于血清中NZP监测 ,IS患儿口服NZP个体差异大 ,最好采用个体化给药。
