Epidural anaesthesia restores pancreatic microcirculation and decreases the severity of acute pancreatitis

Figure 5 Serum amylase levels. In Group 1, serum amylase levels increased from 694 ± units/L 419 prior to AP to 2178 ± 561 units/L (¹P < 0.05, vs serum amylase levels before induction of AP) after 2 h of induction of AP. In Group 2, epidural anaesthesia did not modify serum amylase levels significantly (P = 0.9). In Group 3, serum amylase levels increased to a maximum of 1829±641 units/L after 2 h of initiation of AP and epidural anesthesia. Although this result was lower compared to Group 1, but did not reach statistical significance (³P = 0.08).
