The C-reactive protein, a so-called acute phase protein that indicates the severity of an inflammation, which is well-known to increase regularly after surgery and after ischemia, was significantly correlated with the omeprazole sulfone quotient in the first three days investigated (p = 0.002, p = 0.040, p = 0.011, respectively) with a fairly good correlation (r = 0.758, r = 0.422, r = 0.510, respectively) (Figure 4). Here, CRP is linked to ischemia.
