Abstract
Gastrointestinal tract is a crucial system of concern in critically ill patient.
It is a cornerstone in prognosis of the whole clinical case.
from embryonic phases; GI tract was structured in a balanced hormonal and neural harmony to do its functions in digestion and support the human body with the nutrients.
In ICU stay; as other systems; GI tract can be exposed to imbalanced consequences that affect its harmony producing malfunctions or even failue.
In this study; we tried to spotlight how to assess dysfunction and failure of the GI system in critically ill patient and view schematic thinking about mechanisms of acute gastrointestinal injury and its complications.
As a conclusion from this study; we realized that the big arsenal of strategic medications in our ICUs can do harm to GI system, on the other hand; can do well and enhance the functions of GI system according to several new studies.
Several studies had conclusions about negative drawbacks of Antimicrobials on GI microbiota and hepatotoxic effects of some antimicrobials, NSAIDs and its bad profile with GI mucosal injury and Vasoactive agents and its role in mesenteric ischemia and malapsorbtion.
In the last chapter of this work; we summarized the positive impacts found in some of common ICU medications and blood components on enhancing GI system functions by variable mechanisms.
