Splanchnic ischaemia and multiple organ failure in the critically ill
1Department of Surgery, University of Massachusetts Medical Center, Worcester 01605.
Summary
A new tonometric method helps monitor gastrointestinal perfusion in critically ill patients. This technique identifies splanchnic hypoxia, an early sign of impaired tissue perfusion linked to sepsis and organ failure.
Area of Science:
- Critical care medicine
- Gastroenterology
- Physiology
Background:
- Splanchnic ischemia is a significant concern in critically ill patients.
- Monitoring gastrointestinal mucosal perfusion is crucial for timely intervention.
Purpose of the Study:
- To introduce a safe and simple tonometric method for assessing gastrointestinal mucosal perfusion.
- To investigate the role of splanchnic hypoxia in critically ill patients.
Main Methods:
- Development and application of a tonometric method.
- Identification of intramucosal acidosis as an indicator of splanchnic hypoxia.
Main Results:
- The tonometric method provides a new perspective on splanchnic ischemia.
- Intramucosal acidosis is an early and consistent sign of impaired tissue perfusion.
- Splanchnic hypoxia is potentially linked to sepsis and multiple organ failure.
Conclusions:
- Tonometric assessment of gastrointestinal perfusion is valuable in critical care.
- Early detection of splanchnic hypoxia can guide management strategies.
- Splanchnic hypoxia may be a key factor in the progression to sepsis and organ failure.
