    Abstract:
    BACKGROUND/AIMS: This study aimed to evaluate the effect of octreotide on total effective vascular compliance, measured during rapid volume expansion, in patients with posthepatitic cirrhosis. METHODS: Twenty-nine patients with posthepatitic cirrhosis were randomly assigned to receive a 100-micrograms/h infusion of octreotide after a 100-micrograms bolus (n = 15), or a placebo (n = 14). Hemodynamic measurements were recorded before and 30 min after drug administration. Thereafter, rapid volume expansion was performed in each patient and hemodynamic measurements were repeated immediately after volume expansion. RESULTS: Before volume expansion, placebo administration did not affect any of the hemodynamic values, while the hepatic blood flow was significantly decreased following octreotide administration. After volume expansion, the hemodynamic changes were similar between patients receiving octreotide and the placebo. However, the increase in right atrial pressure from the beginning to the end of volume expansion was higher and the total effective vascular compliance was lower in patients receiving octreotide (+3.5 +/- 0.3 mmHg, p = 0.05 and 1.69 +/- 0.16 ml.mmHg-1.kg-1, p < 0.05) compared to patients receiving placebo (+2.5 +/- 0.3 mmHg, 2.60 +/- 0.34 ml.mmHg-1.kg-1). CONCLUSIONS: The present study suggests that octreotide decreased total effective vascular compliance in patients with posthepatitic cirrhosis. It is possible that, in patients with posthepatitic cirrhosis, venoconstriction was induced following octreotide administration.
