ABSTRACT

Objective: To detect early changes in the levels of gastric CO2 pressure, during hypoperfusion in surgical patients with sepsis.
Design: A prospective, longitudinal, descriptive, observational, cohort study.
Setting: Intensive Care Unit of Hospital Central Norte, PEMEX, Mexico City.
Patients: 42 septic patients with APACHE II scores greater than 13 points with age between 18 and 99 years, of both sexes, that were put under abdominal surgical procedure, to those who it was placed a catheter of Gastric air Tonometry.
Interventions: In order to detect and to deal with opportune form the hypoperfusion in surgical patients with sepsis, we measure the gastric CO2 pressure through a gastric catheter for tonometry.
Measurements and principal results: We measure gastric CO2 pressure (PgCO2), gastric pH (pHi), differential gastric CO2 pressure and CO2 pressure end-expiratory [P (g et) CO2], most the patients studied had an increase in gastric acidity.
Conclusions: The gastric air tonometry is a powerful tool that detects median invasiveness alterations in regional perfusion and predicts complications and mortality in surgical patients with sepsis.
