98例肝硬化食道静脉曲张破裂出血患者随机分为三组 ,34例给予小剂量垂体后叶素 (0 1U/分 )和硝酸甘油联合治疗 ,34例单用垂体后叶素 (0 2U/分 )治疗 ,30例用善得定治疗 ,其止血率分别为 82 4%、5 8 8%和83 3%。经x2 检验联合治疗较单用垂体后叶素有显著性差异 ,而与善得定无显著性差异。表明垂体后叶素与硝酸甘油联用 ,显著增强降低门脉压力的作用 ,疗效显著 Ninety-eight patients with cirrhosis and esophageal variceal bleeding were randomly divided into three groups: 34 patients received low-dose pituitrin (0 1U / min) and nitroglycerin combined therapy and 34 patients received pituitrin alone (0 2U / ), And 30 cases were treated with ZD, the hemostatic rates were 82 4%, 58 8% and 83 3% respectively. The combination of x2 test psoriatic valence compared with single significant difference, but with no good difference was determined. That vasopressin and nitroglycerin combination significantly increased the role of reducing portal pressure, the effect was significant
