目的对平原个体急进高原现场后胃肠型高原反应发生情况及其原因进行调查分析。方法应用消化系统症状调查表对1753例急进高原个体的消化系统症状进行调查,并从中随机抽取20例分别于进入高原前1d、进入高原第3天和第7天行胃镜检查,并对其结果进行分析。结果 1753例急进高原个体中有1097例存在不同程度的消化系统症状(占62.58%),其症状主要有腹胀、食欲不振、恶心、呕吐、腹痛、便秘、腹泻、便血和黑便等,20例进行胃镜检查者,进入高原第3天及第7天胃镜检查阳性例数分别为17例(约85%)和10例(50%),与进入高原前比较,差异均具有统计学意义(P<0.01),胃镜表现主要有胃粘膜出血、充血、淤血、糜烂、溃疡及胆汁返流等,其中1例于进入高原第3天因胃黏膜出血住院治疗。结论平原个体急进高原现场后胃肠型高原反应发生率较高,急性高原缺氧所引发的胃肠道黏膜损伤是导致胃肠型高原反应发生的根本原因。
Objective To investigate the causes and the causes of post-gastrointestinal-type altitude sickness in on-site rapid plateau in plain individuals. Methods A total of 1753 digestive system symptoms were investigated by using the digestive system symptom questionnaire. Twenty patients were randomly selected for gastroscopy from the first day before entering the plateau and the third day and the seventh day after entering the plateau. Analyze. Results There were 1097 digestive symptoms (62.58%) in 1753 acute plateau individuals with symptoms of abdominal distension, loss of appetite, nausea, vomiting, abdominal pain, constipation, diarrhea, bloody stool and melena. For gastroscopy, the number of gastroscopy positive cases on the 3rd and 7th day after entering the plateau were 17 (85%) and 10 (50%), respectively, which were significantly different from those before entering the plateau (P Gastric mucosal bleeding, congestion, congestion, erosion, ulceration and bile reflux were observed in gastroscopy. One case was hospitalized for gastric mucosal hemorrhage on the third day after entering the plateau. Conclusion The incidence of gastrointestinal type plateau reaction is higher in the plateau individuals on the plateau. The gastrointestinal mucosal injury caused by hypoxia on the plateau is the root cause of the gastrointestinal plateau reaction.
