Bronchodilators are used to treat bronchial hyper-responsiveness in asthma. Bronchial hyper-responsiveness may be a component of the acute chest syndrome in people with sickle cell disease. Therefore, bronchodilators may be useful in the treatment of acute chest syndrome.
To assess the benefits and risks associated with the use of bronchodilators in people with acute chest syndrome.
We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group trials register which comprises references identified from comprehensive electronic database searches, handsearching relevant journals and abstract books of conference proceedings. Additional searches were carried out on MEDLINE (1966 to 2002) and EMBASE (1981 to 2002).Date of the most recent search of the Group's haemoglobinopathies register: May 2002.
Randomised or quasi-randomised controlled trials. Trials using quasi-randomisation methods will be included in future updates of this review if there is sufficient evidence that the treatment and control groups are similar at baseline.
We found no trials investigating the use of bronchodilators for acute chest syndrome in people with sickle cell disease.
We found no trials investigating the use of bronchodilators for acute chest syndrome in people with sickle cell disease.
REVIEWER'S CONCLUSIONS: If bronchial hyper-responsiveness is an important component of some episodes of acute chest syndrome in people with sickle cell disease, the use of inhaled bronchodilators may be indicated. There is need for a well-designed, adequately powered randomised controlled trial to assess the benefits and risks of the addition of inhaled bronchodilators to established therapies for acute chest syndrome in people with sickle cell disease.
支气管扩张剂用于治疗哮喘中的支气管高反应性。支气管高反应性可能是镰状细胞病患者急性胸综合征的一个组成部分。因此，支气管扩张剂可能对急性胸综合征的治疗有用。
评估支气管扩张剂用于急性胸综合征患者的益处和风险。
我们检索了Cochrane囊性纤维化和遗传疾病小组的试验注册库，该注册库包括通过全面电子数据库检索、手工检索相关期刊以及会议论文摘要集确定的参考文献。还对MEDLINE（1966年至2002年）和EMBASE（1981年至2002年）进行了额外检索。小组血红蛋白病注册库的最新检索日期：2002年5月。
随机或半随机对照试验。如果有足够证据表明治疗组和对照组在基线时相似，使用半随机化方法的试验将纳入本综述的未来更新中。
我们未发现研究支气管扩张剂用于镰状细胞病患者急性胸综合征的试验。
我们未发现研究支气管扩张剂用于镰状细胞病患者急性胸综合征的试验。
如果支气管高反应性是镰状细胞病患者某些急性胸综合征发作的重要组成部分，则可能需要使用吸入性支气管扩张剂。需要进行一项设计良好、样本量充足的随机对照试验，以评估在镰状细胞病患者的急性胸综合征既定治疗方案中添加吸入性支气管扩张剂的益处和风险。
