支气管哮喘(哮喘)是一种常见病,其发病率为1％,在儿童则可达3％,据测算全国现有患者超过1千万人。由于各种防治哮喘的气雾剂对该病有重要作用,而使用不当又会造成一些严重反应,乃至增加患者死亡率,所以对正确使用气雾剂的问题应该有所认识。 目前临床上常用的气雾剂有以下几类: ①β肾上腺素受体激动剂,包括喘息定、愈喘、舒喘灵、喘立平、羟喘等近20种,为家庭中控制哮喘急性发作及预防运动性哮喘的首选药,作用迅速而强烈。但本类药可引起心肌耗氧增加、心动过速、肌肉震颤等副反应;可能诱发心绞痛、心肌梗塞等,所以伴有冠心病、高血压病及甲亢者应慎用(喘息定应禁用)。此类药如长期、反复、规律性使用或短期大量使用,
Bronchial asthma (asthma) is a common disease with a prevalence of 1% and in children up to 3%. It is estimated that more than 10 million people are currently living in the country. Because various kinds of aerosols for preventing and treating asthma have an important effect on the disease, improper use can cause some serious reactions and even increase the mortality rate of patients, so the problem of proper aerosol application should be recognized. Currently clinically used aerosols are the following categories: ① β-adrenergic receptor agonists, including asthma set, asthma, salbutamol, asthma, such as nearly 20 kinds of asthma, asthma for the family to control the acute attack And prevention of exercise-induced asthma drugs, the role of rapid and strong. However, this class of drugs can cause increased myocardial oxygen consumption, tachycardia, muscle tremors and other side effects; may induce angina pectoris, myocardial infarction, so with coronary heart disease, hypertension and hyperthyroidism should be used with caution (wheezing should be disabled) . Such drugs such as long-term, repeated, regular use or short-term mass use,
