[摘要]目的: 观察大剂量甲氨蝶呤(MTX)连续24h持续静脉输注 治疗 儿童急性淋巴细胞白血病的临床耐受性。 方法 : 72例次急性淋巴细胞白血病患儿进行大剂量甲氨蝶呤连续24h持续静脉输注,第36h亚叶酸钙解救,检测36h、48h、72h MTX血药浓度,观察不良反应发生率。 结果: 不良反应表现为消化道症状、肝功能损害和Ⅰ°~Ⅱ°白细胞减少、Ⅰ°~Ⅱ°口腔粘膜损害,无严重不良反应发生。92.5%的患儿72h MTX血药浓度<0.1μmol.L。 结论: 大剂量MTX加亚叶酸钙解救治疗儿童急性淋巴细胞白血病,耐受性较好。个别患儿出现排泄延迟,通过监测MTX血药浓度,增加亚叶酸钙解救次数,可防止严重不良反应发生。
