为了解不同剂量酚妥拉明治疗毛细支气管炎喘憋的疗效，对６７例病儿随机分为酚妥拉明第１组（０６～１ｍｇ／ｋｇ／次）及第２组（０２５～０５ｍｇ／ｋｇ／次），对比观察毛细支气管炎喘憋症状消减情况，着重观察了两组所引起的不良反应。结果两组对比喘憋症状消减情况无显著差异（Ｐ＞００５）。第１组所致不良反应严重，而被迫停药者３例，第２组无此弊端。认为第２组所用剂量值得推广应用。 To understand the efficacy of different doses of phentolamine in the treatment of bronchiolitis and wheezing, 67 children were randomly divided into the first group (06 ~ 1 mg / kg) and the second group (06 ~ 25 ~ 0  5mg / kg / time), compared to observe the reduction of symptoms of bronchiolitis wheezing, focusing on the two groups caused by adverse reactions observed. Results There was no significant difference between the two groups in reducing the symptoms of wheezing (P> 005). The first group caused serious adverse reactions, and was forced to stop in 3 cases, the second group without this drawback. It is considered that the dose used in Group 2 is worthy of promotion and application.
