急性胃肠道粘膜损伤(应激性溃疡)是ICU病人常见的并发症,与该损伤相关的出血率较低,呕血或黑便发生率7～14％。但伴有其它并发症如休克、败血症、腹膜炎、急性呼吸衰竭、急性肾衰和黄疸的病人,出血率较高。Hastings首先提出隐性上消化道出血(GB)的概念,以此来证明GB和ICU病人危险因素数量间及预防性中和胃酸效应间的直接关系。但Hastings及其他一些作者的研究仍有不足之处。本文作者为此作了改进,采用下列方法:①选用胃隐血试剂
Acute gastrointestinal mucosal injury (stress ulcer) is a common complication in patients with ICU, the bleeding rate associated with the injury is low, the incidence of hematemesis or melena 7% to 14%. However, patients with other complications such as shock, septicemia, peritonitis, acute respiratory failure, acute renal failure and jaundice have a higher rate of bleeding. Hastings first proposed the concept of latent upper gastrointestinal hemorrhage (GB) to demonstrate the direct relationship between the number of risk factors for GB and ICU patients and their prophylactic and gastric acid effects. However, research by Hastings and others is still inadequate. The author of this article made improvements, using the following methods: ① use of gastric occult blood reagent
