1、两类胃酸分泌抑制剂治疗急性消化性溃疡出血的比较研究作者:曹义战,刘莉,王伯良,陆将,何保健,仲月霞,宋德根,江华【关键词】H2,受体拮抗剂 关键词:H2受体拮抗剂;质子泵抑制剂;消化性溃疡 中图号:R573.1 摘要:目的比较抑酸药H2受体拮抗剂(H2A)与质子泵抑制剂(PPI)对消化性溃疡出血的疗效.方法①30只SD大鼠随机分成6组,制备急性胃溃疡出血模型,以不同pH值的缓冲液冲洗胃溃疡部位后记录其胃粘膜出血时间(GMBT).②24例消化性溃疡急性出血患者,随机分2组,24h内洛赛克组静
2、滴40mg洛赛克,法莫替丁组静滴40mg法莫替丁,动态测定给药前1h及给药后24h胃内pH值.③回顾性分析272例应用洛赛克(40mg静滴,1次d-1)与270例应用法莫替丁(40mg静滴,2次d-1)的消化性溃疡出血患者手术率与死亡率.结果当pH≥6.0时大鼠GMBT明显缩短(P<0.05).胃内pH值监测结果,用药后各组pH>4.0,pH>6.0的时间,洛赛克组比法莫替丁组显著延长(P<0.01).洛赛克治疗组手术率比法莫替丁治疗组明显减低(P<0.05),而死
3、亡率无显著差异.结论对急性消化性溃疡出血,质子泵抑制剂的抑酸止血效果明显高于H2受体拮抗剂.10 Keywords:H2-receptorantagonist;proton-pumpinhibitor;pepticulcer Abstract:AIMToinvestigatetherapeuticeffectsofH2-re-ceptorantagonists(H2A)andproton-pumpinhibitors(PPI)onpepticuleerbleeding.METHODSThir
