一项雷尼替丁和硫糖铝预防自发性脑内出血患者胃出血的随机安慰剂对照试验

A randomized placebo controlled trial of ranitidine versus sucralfate in patients with spontaneous intracerebral hemorrhage for prevention of gastric hemorrhage

Aim: Due of paucity of studies on stress ulcer prophylaxis in intracerebral hemorrhage (ICH), we have evaluated the usefulness of ranitidine and sucralfate in preventing gastric hemorrhage (GH) in patients with ICH. Subjects and methods: In a hospital-based randomized placebo-controlled study, patients with CT-proven ICH within 7 days of ictus were randomized into ranitidine 50 mg i.v. eight hourly, sucralfate 1 g six hourly and placebo groups. Patients were conservatively managed. Primary endpoint was occurrence of GH within 15 days of ictus and secondary endpoint 1-month mortality. Results: The mean age of the patients was 57.2 (range 25-90) years and 40 were females. There were 45 patients in ranitidine, 49 in sucralfate and 47 in placebo group. Demographic, clinical and radiological features were not significantly different in 3 groups. GH occurred in 11 (23.4%) patients in placebo, 5 (11.1%) in ranitidine and 7 (14.3%) in sucralfate group, which was not significant. Only one female had GH. There were 13 (27.7%) deaths in placebo, 5 (11.1%) in ranitidine and 12 (24.5%) in sucralfate group. Pneumonia occurred in placebo group in 5 (10.6%), ranitidine in 2 (4.4%) and sucralfate in 5 (10.2%) patients, which was not significantly different. Co nclusion: Ranitidine and sucralfate do not seem to significantly prevent GH or r educe 1-month mortality.
