15 (R)-15-methyl prostaglandin E2 does not prevent gastrointestinal bleeding in seriously ill patients

, : 15 (R)-15-methyl prostaglandin E2 does not prevent gastrointestinal bleeding in seriously ill patients. American Journal of Surgery 147(4): 451-455

A prospective, randomized trial was designed to compare the relative efficacy of 15 (R)-15-methyl prostaglandin E2 with antacid (usually Mylanta II) in 46 patients admitted to a respiratory-surgical intensive care unit. Bleeding was assessed by a modification of the Hemoccult slide test. Three of 22 patients in the antacid group bled, and 12 of 24 patients in the prostaglandin group bled, for a highly significant difference (p = 0.008). Patients in whom prophylaxis failed tended to have a greater number of risk factors. Other prostaglandin analogues that do not require conversion from an inactive to an active form, may be more useful than the agent we studied. Based on currently available data, the hourly titration of the gastric juice to a pH of greater than 3.5 remains the preferred method of prophylaxis for acute bleeding from the stomach in seriously ill patients.
