Abstract:
Objective To investigate the relationship between gastric tonometer and stomach tube methods for determining gastrointramucosal pH (pHi) during the operation. Methods General anesthesia was induced in thirty patients. After endotracheal intubation,electrocardiography, blood pressure,HR and SpO 2 were monitored . The gastric juice were collected by the gastric tonometer and stomach tube methods to determine the PCO 2 at 30,60 and 120 min following anesthesia respectively, and at the same time the arterial blood samples were taken to measure the HCO- 3 concentration with American Corning automatic blood-gas and eletrolytes analyzer.Intramucosal pH was calculated using Henderson-Hasselbalch equation. Results Through correlation and regression analysis , there were positive correlations in the pHi determined at three time points between gastric tonometer and stomach tube methods(r=0.699, 0805 and 0792, P
