目的对平原个体急进高原后胃黏膜出血机制进行探讨。方法对20例由平原急进高原个体于进入高原前、进入高原第3天和第7天进行胃镜检查,及进入高原后消化系统的症状发生情况进行调查,并对其胃黏膜出血情况及其机制进行探讨。结果 20例进行胃镜检查者,胃黏膜出血表现明显,与进入高原前比较,差异具有统计学意义(P<0.01)。镜下主要表现有胃黏膜充血、淤血、出血、糜烂、溃疡。其中13例有不同程度的消化系统症状(65%),主要有食欲不振、腹胀、恶心、呕吐、腹痛、便秘和黑便等。结论由于高原急性缺氧及高原恶劣环境引起的各种心理应激等的影响,急进高原个体的胃溃疡、胃黏膜出血的发生率高。应加强有针对性的胃黏膜保护,这对促进急进高原者的身体健康,提高其高原适应能力和降低急性高原病的发病率无疑具有积极的意义。
Objective To investigate the mechanism of gastric mucosal hemorrhage after the individual in the plain hurried into the plateau. Methods 20 cases of acute rapid plateau from the plain before entering the plateau, into the plateau 3 days and 7 days for gastroscopy, and into the plateau after the digestive system to investigate the incidence of symptoms, and its gastric mucosal bleeding and its mechanism To explore. Results 20 patients underwent gastroscopy, gastric mucosal bleeding significantly, compared with before entering the plateau, the difference was statistically significant (P <0.01). Microscopic appearance of gastric mucosal congestion, congestion, bleeding, erosion, ulcers. Of these, 13 had varying degrees of digestive symptoms (65%), mainly with loss of appetite, bloating, nausea, vomiting, abdominal pain, constipation and melena. Conclusion The incidence of gastric ulcer and gastric mucosal hemorrhage in acute altitude plateau individuals is high due to various psychological stress caused by acute hypoxia in plateau and severe environment in plateau. The targeted gastric mucosal protection should be strengthened, which undoubtedly has a positive meaning to promote the health of those who rush into the plateau, improve their plateau adaptive capacity and reduce the incidence of acute mountain sickness.
