Prolonged intestinal mucosal acidosis is associated with multiple organ failure in human acute pancreatitis: Gastric tonometry revisited

Figure 3 Dynamics of the daily lowest pHi values in relation to the different outcomes of acute pancreatitis. In the survivor group (Group 2) pHi data were sorted to reflect the emergence or absence of MODS. In the absence of MODS pHi values stayed close to the physiological range, returning from the initial depression to normal by d 3. In patients with MODS initial pHi values were considerably lower, but a return to normal values was detectable. In the non-survivor group (Group 1) each patient developed MOF, therefore values were sorted to reflect the early or late appearance of this complication. All pHi values continued to stay at subnormal levels from the day of admission, and never returned to normal. (Values represent median and range).
