1、糖皮质激素治疗肝衰竭疗效和安全性的meta分析,临床医学硕士论文摘 要 目的 :采用meta分析方式方法评价糖皮质激素治疗肝衰竭的疗效及安全性。 方式方法 :使用计算机检索从建库起至2020年8月发表的相关中英文文献。检索了万方数据库、中国期刊全文数据库CNKI、中文科技期刊全文数据库VIP、Web of science、Pub Med、Embase及CochraneLibrary。应用Rev Man5.3软件进行分析,计数资料采用比值比、计量资料采用加权均数差进行统计学分析。 结果 :共纳入了31篇随机对照试验的文献。 meta分析显示,糖皮质激素治疗组患者总体病死率低于对照组患者;以糖皮质
2、激素种类为亚组分析,使用地塞米松、甲泼尼龙或未明确分类激素主要为中长效糖皮质激素治疗的患者病死率降低,使用泼尼松龙或氢化可的松治疗的患者病死率与对照组相比没有显着差异。实验室指标方面,糖皮质激素治疗组总胆红素、丙氨酸氨基转移酶及凝血酶原活动度改善情况优于对照组,但白蛋白改善情况两组差异无统计学意义。并发症方面,糖皮质激素治疗组继发感染和肝性脑病的发生率低于对照组,两组患者消化道出血和肝肾综合征的发生率差异无统计学意义。 结论:糖皮质激素用于治疗肝衰竭可降低肝衰竭患者的病死率,改善相应实验室指标,且不增加并发症的发生风险。华而不实地塞米松和甲泼尼龙等中长效激素降低病死率的效果较好。 本文关键词语
