Is the incidence of hemorrhagic stress ulceration in surgical critically ill patients affected by modern antacid prophylaxis?

Hemorrhagic stress ulceration (HSU), a known complication in the Surgical Intensive Care Unit (SICU) patient population, has a reported incidence rate of 25 to 75 per cent. The goal of this study was to evaluate whether the use of prophylactic antacid agents significantly reduced the frequency of HSU in critically ill patients, or whether improved care reflected the decrease in HSU. A total of 425 consecutive patients were reviewed for occurrence of HSU; of these, 304 were eligible for the study.
