本文介绍阿托品的迷走神经阻滞作用与患者夜间最大呼气流量(PEFR)关系的研究。夜间哮喘发作10例病人中,男女各5例,年龄26～52岁。哮喘发作年限2～25年。患者随机在第1天的4am 和4pm,静注阿托品30μg/kg 或安慰剂。第二天两组交换疗法。观察阿托品的迷走神经阻滞作用和夜间最大呼气流量的关系。本组夜间哮喘发作患者,其白天最大呼 This article describes the study of the relationship between vagal block in patients with atropine and the maximum expiratory flow at night (PEFR). Nighttime asthma attack in 10 patients, 5 men and women each, aged 26 to 52 years. Asthma attack duration of 2 to 25 years. Patients were randomized to either atropine 30 μg / kg or placebo at 4 and 4 pm on day 1. The next two days exchange therapy.
