Abstract

Rectal suppositories as an alternative to intravenous aminophylline in the management of recurrent apnoea were studied in 41 preterm infants of mean gestation 28.3 weeks and mean birthweight 1176 g. Therapeutic blood concentrations were obtained two hours after a rectal loading dose of 10 mg/kg, with steady concentrations and maximum reduction in apnoeic episodes (from a mean of 0.5 per hour to 0.09 per hour) within 24 hours on a maintenance dose of 10 mg/kg/day. There was good correlation between the rectal dose and the plasma theophylline concentration. Several infants showed a significant reduction in Pco2 when treated with aminophylline. Side effects were related to the plasma theophylline concentration and were not seen at concentrations less than 14 mg/l.

摘要

在41例平均孕周28.3周、平均出生体重1176克的早产婴儿中,研究了直肠栓剂作为静脉注射氨茶碱治疗反复呼吸暂停的替代方法。在给予10mg/kg的直肠负荷剂量两小时后,达到治疗血药浓度,在维持剂量为10mg/kg/天的情况下,24小时内血药浓度稳定,呼吸暂停发作次数最大程度减少(从平均每小时0.5次降至每小时0.09次)。直肠剂量与血浆茶碱浓度之间存在良好的相关性。几名婴儿在接受氨茶碱治疗时,Pco2显著降低。副作用与血浆茶碱浓度有关,在浓度低于14mg/l时未出现。
