Background: The efficacy of octreotide, the synthetic analogue of the hormo
ne somatostatin, for the treatment of acute pancreatitis is controversial.
Octreotide has been commonly administered in subcutaneous bolus injections;
however, continuous intravenous infusion may be advantageous for acute con
ditions. Methods: Acute experimental pancreatitis was induced in rats by in
traparenchymal injections of 1 mi 10% sodium taurocholate, and octreotide (
1 mu g/kg/h, dissolved in physiological solution, intravenously was started
4 h later and continuously infused for 48 h. Physiological solution infusi
ons, in identical volumes, were used in the controls. The following paramet
ers were examined: mortality; macroscopic and histological damage; hematocr
it; plasma pH; acid-base balance; serum glucose; calcium, and amylase. Resu
lts: Octreotide treatment had a striking effect on mortality: 8.3 versus 91
.6% in the treatment and control groups, respectively (p < 0.001), Octreoti
de also ameliorated pancreatic edema and intestinal dilatation, and had sig
nificant beneficial effects on histopathological damage and the biochemical
alterations which are associated with acute pancreatitis. Conclusions: Con
tinuous intravenous octreotide infusion is a potentially efficacious therap
eutic method for acute pancreatitis.
