  • Title: Influence of somatostatin on splanchnic haemodynamics in patients with liver cirrhosis.

    Journal: Clin Physiol; 1984 Feb; 4(1):5-11. PubMed ID: 6141861.
    Abstract:
    The influence of intravenous somatostatin infusion (7.6 micrograms/min) on systemic and splanchnic haemodynamics was examined in 10 patients with liver cirrhosis and portal hypertension. The hepatic vein catheter technique was employed and indocyanine green dye was injected to evaluate hepatic blood flow. Mean wedged hepatic venous pressure fell from 24.9 +/- 2.8 in the basal state to 21.4 +/- 3.2 mmHg (P less than 0.2) at 60 min of infusion and the mean arterial pressure decreased from 87 +/- 5 to 80 +/- 6 mmHg (P less than 0.05). The rate of indocyanine green dye disappearance decreased from 8.7 +/- 1.9 to 6.6 +/- 1.7%/min (P less than 0.001) during the infusion, indicating decreased hepatic blood flow. Arterial-hepatic venous oxygen differences rose from 69 +/- 11 to 78 +/- 11 ml/l. Blood glucose levels fell from 4.84 +/- 0.31 to 3.79 +/- 0.33 mmol/l at 60 min of infusion (P less than 0.005). It is concluded that a continuous infusion of somatostatin in patients with liver cirrhosis and portal hypertension causes a decreased hepatic blood flow with augmented hepatic oxygen extraction and a modest reduction in mean wedged hepatic venous pressure. In view of the magnitude of the observed haemodynamic changes the findings do not suggest an important role for somatostatin in the treatment of patients with bleeding oesophageal varices.
