作者采用双盲法对114名作双对比钡餐检查的病人使用低张药物的效果作了对照研究和统计分析。病人随机分为三组,分别在造影前静脉注射丁溴山莨菪碱20mg、胰高糖素0.5mg 或蒸馏水(对照组)。每个患者均摄取相同的4个位相,根据胃扩张的程度,胃粘膜的涂布,十二指肠扩张的程度及十二指肠粘膜涂布的情况,定为三个等级(差、好、优),作卡方检验。结果表明,丁溴山莨菪碱组和胰高糖素组十二指肠扩张和涂布均比对照组为佳,卡方检验差别有显著性意义。但该两组间差别无显著性意义。至于胃的扩张程度和胃粘膜的涂布,不管使用低张药物与否,差别均无显著性意义。胰
The authors used a double-blind method to compare the effects of low-tension drugs on 114 patients undergoing double-contrast barium meal examinations. The patients were randomly divided into three groups and were intravenously injected with buprenorphine 20 mg, glucagon 0.5 mg or distilled water (control group) before contrast. Each patient took the same four phases, according to the extent of gastric dilatation, the gastric mucosal coating, the degree of duodenal dilatation, and the duodenal mucosal coating, which was rated as three grades (poor, good). , excellent), for the chi-square test. The results showed that the expansion and spread of duodenum in the butbu erythramine group and glucagon group were better than those in the control group, and there was a significant difference in the chi-square test. However, there was no significant difference between the two groups. As for the extent of gastric dilatation and the application of gastric mucosa, there was no significant difference between the use of hypotonic drugs or not. pancreatic
