床边急诊胃镜诊治致死性非静脉曲张性上消化道大出血

目的探讨床边急诊胃镜在急性重症非静脉曲张性上消化道大出血诊治中的作用。方法154例致死性非静脉曲张性上消化道大出血病人，入院后即刻行床边急诊胃镜明确病因、部位及出血情况后胃镜下注射肾上腺素-利多卡因-高渗盐水止血。结果急诊诊断率94．2％，总有效率92．9％，再出血率9．0％，无不良反应。结论床边急诊胃镜能有效诊断急性致死性非静脉曲张性上消化道大出血，内镜下注射肾上腺素-利多卡因-高渗盐水能有效止血，安全、简便。

Emergent endoscopic injection treatment for critical nonvariceal upper GI bleeding

Objective]To explore the effect of emergent endoscopic injection on control of nonvariceal upper GI bleeding. Total of 154 patients with lethal nonvariceal upper GI bleeding were included in the study, all were treated with injection of adrenalin-saline according to their endoscopic bleeding situation. The endoscopic situation of 94.2% of patients were diagnosed immediately. Initial hemostasis could be achieved in 92.9% of patients and rebleeding rate was 9.0%. Conclusions] Emergent application of endoscopic adrendine-saline injection is a safe and effective method for lethal nonvariceal upper GI bleeding.
