据近年报告,无论口服或静脉注射舒喘灵或静脉注射、皮下注射间羟舒喘宁(Terbutaline)都可引起低血钾,而口服和皮下注射间羟舒喘宁已在肺科广为应用,但缺少很好的对照研究。本文研究皮下1次注射治疗剂量的间羟舒喘宁后血钾变化的动力学过程。方法:7例志原者均不吸烟,男3例、女4例,年龄19～40岁(平均29岁),皆具有典型哮喘病史,并 According to recent reports, both oral and intravenous salbutamol or intravenous injection, subcutaneous injection of hydroxybutarnone (Terbutaline) can cause hypokalemia, oral and subcutaneous injection of oxycholic acid has been widely used in pulmonary disease , But lacking good control studies. This article studies the kinetics of serum potassium changes after a single subcutaneous injection of methotrexate. Methods: None of the seven patients were smoked. There were 3 males and 4 females, aged from 19 to 40 years old (average 29 years old), all with typical asthma history and
