Fig. 5. Changes in pHi in the stomach (continuous line) and the jejunum (dotted line). For the sepsis group, at t = 0, pHi was 7.29 in the stomach mucosa (which is reported to be normal for pigs 43) and 7.30 in the jejunal mucosa. The decrease in pHi during hypodynamic septic shock to 7.07 in the jejunum and 7.08 in the stomach, as well as the increase during hyperdynamic sepsis (after intravenous fluid load at 240 min), were virtually in parallel. For the controls, pHi in both stomach (continuous line) and in the jejunum (dotted line) were quite stable. *P < 0.05, **P < 0.01 compared with baseline. #P < 0.05, ##P < 0.01 compared with the control group.
