Gastric tonometry: early warning of tissue hypoperfusion
1Department of Trauma, Loyola University Medical Center, Loyola University of Chicago, Maywood, Illinois, USA.
Abstract:
Perfusion status of the critically ill and injured has, in the past, been assessed by indices such as blood pressure (BP), heart rate, and urine output. These indices represent global perfusion and may not reflect regional blood-flow abnormalities. These hypoperfused regions may lead to organ failure and subsequent death. The gastrointestinal (GI) tract remains one of these tissue beds that is extremely sensitive to low-flow states. Gastric tonometry is a noninvasive means in which these early symptoms of low flow may be monitored with early interventions to optimize tissue perfusion and patient outcome.

Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
