上消化道大出血是消化科最常见的急症,其病死率高达20～40％。有效地控制出血是降低死亡率的关键。上消化道出血最常见的原因是消化性溃疡和食道胃底静脉曲张破裂出血,后者的死亡率高达50％,其常规治疗是用垂体后叶素、三腔管压迫止血、硬化剂治疗及急诊手术治疗。垂体后叶素能降低门静脉压力。但易引起心绞痛、肠痉挛等;三腔管压迫病人痛苦大,停止压迫后再出血较高;硬化剂治疗在我国尚不普及;急诊手术成功率低,潜在危险性大。近年来国外用生长抑素治疗难治性上消化道大
Upper gastrointestinal bleeding is the most common emergency department of digestive diseases, the mortality rate as high as 20 to 40%. Effective control of bleeding is the key to reducing mortality. The most common cause of upper gastrointestinal bleeding is peptic ulcer and esophageal variceal bleeding, the latter of up to 50% mortality, the conventional treatment is pituitrin, three-lumen tube hemostasis, sclerotherapy and Emergency surgery. Pituitrin reduces portal pressure. But easily lead to angina pectoris, intestinal spasm, etc .; triple-lumen oppression patients with pain, stop bleeding after oppression higher; sclerotherapy is not yet universal in our country; emergency surgery, low success rate, potentially dangerous. In recent years abroad with somatostatin refractory upper gastrointestinal treatment
