1、谷氨酰胺双肽在腹部外科围手术期临床应用的系统评价中国临床营养杂志CHINESEJOURNALOFCLINICALNUTRITION•论著.谷氨酰胺双肽在腹部外科围手术期临床应用的系统评价郑亚民,伍晓汀#,李月春,钱昆,张明鸣(四川大学华西医院普通外科,成都610041)摘要:目的评价谷氨酰胺双肽在腹部外科围手术期的临床应用和卫生经济学价值。方法通过计算机检索Cochrane图书馆、MEDLINE、EMBASE数据库和CNKI、VIP、CBMDISK数据库,评价纳人随机对照研究,应用RevMan4.2软件进行Meta分析。结
2、果纳人15个临床研究(》=531)。Meta-分析显示,谷氨酰胺双肽增强的肠外营养与对厢组比较可使患者临床感染率降低至34%,95%CI[0.19,0.62],P=0.0004;患者平均总住院时间缩短3.20天,95%CI[-4.95,-1.44],P=0.0004;并可提髙术后肠外营养效益,与对照组比较,累积氮平衡提髙3.96g,95%CI[3.07,4.96],P<0.00001。结论谷氨酰胺双肽在治疗剂量,能够有效降低腹部外科手术患者术后感染风险,促进负氮平衡改善,缩短住院时间;但目前的证据还无法充分肯定是否对手术患
3、者死亡率有影响。在卫生经济学方面,有研究发现谷氨酰胺双肽可以減少平均住院花费,但尚需大样本进一步深人研究。关键词:谷氨酰胺双肽;肠外营养;系统评价;外科中明分类号:R459.3文献标识码:A文章编号:1008-5882(2005)04-0210-06ClinicalApplicationofGlutamineDipeptideinAbdominalSurgery:ASystematicReviewZhengYa-min,WuXiao-ting*,LiYue-chun,QianKun,ZhangMing-ming(Depar
