Stress-related mucosal disease (SRMD) is characterized by acute multiple ulcerations of the upper gastrointestinal submucosa, which may be either diffuse or focal, superficial or deep.(1,2) SRMD can result from any number of factors that increase physiologic demands, though the most common etiology is splanchnic hypoperfusion resulting in gastric mucosal ischemia.(3,4) Patients in intensive care units (ICUs), who are at elevated risk for splanchnic hypoperfusion, are prone to developing stress ulcers and associated gastrointestinal bleeding.
