Abstract
AIM: To observe the predictive value of gastric intramucosal pH (pHi) for critical patients.
METHODS: The pHi of 32 ICU patients was measured with a self-made gastrointestinal tonometer, and the APACHE II score was determined simultaneously.
RESULTS: pHi of the nonsurvivors was significantly lower than that of the survivors (P < 0.05). The pHi was remarkably higher in the nonsepsis group than in the sepsis group (P < 0.01). Only in multiple organ failure groups, pHi was found statistically lower (P < 0.05).
CONCLUSION: pHi may be the most simple, reliable, sensitive and accurate parameter to indicate the adequacy of tissue oxygenation, and it may be widely used in ICU monitoring in near future.
