What is the role of gastrointestinal hypoperfusion and gastric tonometry in critical illness?
This review emphasizes the potential importance of gastrointestinal hypoperfusion in critical illness while acknowledging the complexities and limitations of current monitoring techniques like gastric tonometry.
Gastric tonometry use warrants caution in critical illness; leaves open the precise role of gastrointestinal hypoperfusion for prospective validation.
An association between abnormal gastrointestinal perfusion and critical illness has been suggested for a number of years. Much of the data to support this idea comes from studies using gastric tonometry. Although an attractive technology, the interpretation of tonometry data is complex. Furthermore, current understanding of the physiology of gastrointestinal perfusion in health and disease is incomplete. This review considers critically the striking clinical data and basic physiological investigations that support a key role for gastrointestinal hypoperfusion in initiating and/or perpetuating critical disease.
