儿童茶碱有效血药农度范围窄(5～15μg/ml)。本文应用荧光偏振免疫分析仪(TDX)监测31例小儿茶碱血清农度,其结果表明:不在有效农度范围内为20例(占64.5％),在有效血农度范围内为11例(占35.5％)。提示氨茶碱临床应用血浓监测是非常必要的,尽可能做到用药个体化,并开展临床药物疗效评价工作。 Children’s theophylline effective range of narrow blood (5 ~ 15μg / ml). In this paper, 31 cases of pediatric theophylline serum pests were monitored by fluorescence polarization immunoassay analyzer (TDX). The results showed that 20 cases (64.5%) were not within effective range of peasants and 11 cases were within range of effective peasants’ Accounting for 35.5%). It is suggested that the clinical application of aminophylline blood concentration monitoring is very necessary, as far as possible individualized medication, and to carry out clinical drug efficacy evaluation.
