Abstract:Abstract: Objective To discuss and compare the efficacy of gastroscopy with spray and injection norepinephrine bitartrate in treatment of acute non-variceal upper gastrointestinal bleeding. Methods From January 2015 to December 2017, 92 cases of acute non-variceal upper gastrointestinal bleeding patients were selected as clinical research subjects. The patients were randomly divided into observation group (n = 47) and control group (n = 45). The acute non-variceal upper gastrointestinal bleeding patients in the observation group were treated with gastroscopy with injection norepinephrine bitartrate. The acute non-variceal upper gastrointestinal bleeding patients in the control group were treated with gastroscopy with spray norepinephrine bitartrate. The clinical treatment, changes in clinical indicators, adverse reactions of the patients in two groups were compared and analyzed. Results Compared with control group, the acute non-variceal upper gastrointestinal bleeding patients in the observation group, the clinical treatment effective rate was 57.45% (27/47) and the total effective rate was 91.49% (43/47), there were increased significantly, while the inefficiency rate was 8.51% (4/47), there was decreased significantly, the differences were significant statistically (P < 0.05); the acute non-variceal upper gastrointestinal bleeding patients in the observation group, the success rate of hemostasis was 91.49% (43/47), there was increased significantly, the differences were significant statistically (P < 0.05), meanwhile, the rate of concurrent rebleeding was 6.38% (3/47) and the rate of emergency surgery was 2.13% (1/47), there were both decreased, but the differences were not significant statistically (P > 0.05); the acute non-variceal upper gastrointestinal bleeding patients in the observation group, the total incidence of adverse reactions was 10.65% (5/47), included abdominal discomfort, stool frequency, flatulence, unstable blood pressure, there was decreased significantly, the differences were significant statistically (P < 0.05). Conclusion Gastroscopy with injection norepinephrine bitartrate has more effective effect than the spray administration for patients with acute non-variceal upper gastrointestinal bleeding, and the prognosis was well and complications were fewer.
