茶碱中毒可危及生命,严重者可因心脏停搏而死亡。血糖过高和血钾过低是茶碱中毒常见的表现,且与血浆茶碱浓度有关。低血钾还可能增加茶碱的毒性,引起严重的心律失常;常以静脉输氯化钾治疗,严重病例以炭血输注清除血流中的茶碱。肾上腺素能神经系统对调节细胞内外钾离子的分布具有重要的作用。心得安阻断β-肾上腺素能神经,可提高血钾浓度。茶碱中毒的低血钾显然也是钾离子由细胞外转移到细胞内所致,作者报道1例14岁无哮喘女孩茶碱严重过量,给予静脉输心得安,观察该
Theophylline poisoning can be life-threatening, in severe cases, death due to cardiac arrest. Hyperglycemia and hypokalemia is a common manifestation of theophylline poisoning, and the concentration of plasma theophylline. Hypokalemia may also increase the toxicity of theophylline, causing serious arrhythmia; often intravenous potassium chloride treatment, severe cases of carbon black blood flow in the removal of theophylline. The adrenergic nervous system plays an important role in regulating the distribution of potassium ions both inside and outside the cell. Adrenaline block β-adrenergic nerve can increase serum potassium concentration. Theophylline hypokalemia is apparently caused by the transfer of potassium ions from the cell to the cells caused by the author reported a 14-year-old girl without asthma in severe over-theophylline given intravenous Andean, the observation of the
