A randomised, double-blind trial of atropine, atropine plus papaveretum, and atropine plus diazepam given intramuscularly as premedication for fibreoptic bronchoscopy in 60 patients showed no difference between the three regimens as assessed by bronchoscopist or patient. Bronchoscopists frequently attributed a sedative action to atropine alone and their assessment of tolerance and sedation was more optimistic than that of the patients. In a second study comparing intravenous diazepam (10 mg) with saline, after prior intramuscular atropine (0.6 mg), both the bronchoscopists and the patients noted a significant sedative effect of diazepam, and coughing was reduced by diazepam.
一项针对60例患者进行的随机双盲试验,比较了肌肉注射阿托品、阿托品加罂粟碱以及阿托品加地西泮作为纤维支气管镜检查术前用药的效果。结果显示,支气管镜检查医师或患者评估发现,这三种用药方案之间并无差异。支气管镜检查医师常认为阿托品本身具有镇静作用,他们对耐受性和镇静效果的评估比患者更为乐观。在第二项研究中,先肌肉注射阿托品(0.6毫克),然后比较静脉注射地西泮(10毫克)和生理盐水的效果。结果发现,支气管镜检查医师和患者均指出地西泮具有显著的镇静作用,且地西泮可减少咳嗽。
