Effect of peroral antacid treatment in patients with acute upper gastrointestinal haemorrhage: a randomized controlled trial.

During recent years, it has been reported that antacids have a beneficial prophylactic effect in critically ill patients regarding upper gastrointestinal bleeding. In these trials rather complicated treatment schedules and high doses of antacids were used. The present study was designed to investigate the therapeutic efficacy of a more practical antacid treatment regimen in patients with haematemesis and/or melaena. Ninety patients, hospitalized for haematemesis and/or melaena within the past 24 hours, were included to double-blind treatment with antacids or placebo for 7 days. The dose, 20 ml liquid antacid (Balancid) with a neutralizing capacity of 105 mmol, was administered each second hour during waking hours. The groups were comparable regarding incidence of ulcer disease, age, sex, acid secretion, and usage of aspirin. Continuous bleeding or rebleeding was recorded in 15 of the 43 patients in the antacid group (34.9%), compared to 19 of the 47 patients in the placebo group (40.4%), the difference not being statistically significant. Furthermore, the requirement of blood transfusions was not significantly different in the two groups. In conclusion, the haemostatic effect of the antacid treatment regimen used in the present study was not significantly superior to placebo in patients with endoscopically verified acute upper gastrointestinal haemorrhage.
