for the,prevention of,postoperative nausea,and vomiting(PONV),糖皮质激素在多数情况下,被用来减少炎症和组织,损伤下，包括炎症性肠病、,风湿性关节炎、和一些,恶性肿瘤。糖皮质激素具,有强大的免疫调节作用,用于治疗急性同种异体排,斥反应，同时也有止,吐作用，例如地塞米松常,常被用来预防术后恶心,呕吐,Company

of,glucocorticoid,-related,adverse effects.,长期使用糖皮质激素治疗,具有许多相关副作用。但,是单次围手术期剂量的地,塞米松是否增加这些副作,用并不清楚。这是由于许,多已出版研究并没有足够,的动力对此临床相关副反,应进行检测，同时也是由,于很多研究将具有糖皮质,激素相关副反应的高风险,患者排除在研究之外的原,因,Company
