title: Effectiveness of normal saline solution, dextran 40 or dextran 75, and aprotinin (Trasylol) on renal blood flow preservation during acute canine pancreatitis.
abstract: A decrease in renal blood flow is believed to be important in the genesis of the acute renal failure of acute pancreatitis. In some instances, this decrease is undoubtedly due to hypovolemia, whereas in other instances, a circulating vasotoxic agent, possibly trypsin, has been incriminated. Using a canine model of pancreatitis induced by retrograde injection of bile along the pancreatic duct, the effects on renal blood flow of correcting the hypovolemia or administering aprotinin (a trypsin inhibitor) were studied using externally applied flow probes. Correcting the hypovolemia with N saline solution had no effect; the renal blood flow continued to decrease (p less than 0.05). When dextran 40 or dextran 75 was employed, the decrease in renal blood flow was prevented. After the administration of aprotinin, the renal blood flow actually increased (p less than 0.025) compared with preadministration values. It appears that aprotinin may have played a role in preventing this serious complication of pancreatitis.
