Octreotide is thought to reduce splanchnic and variceal blood flow with minimal effects on the systemic circulation in cirrhotic patients with portal hypertension. However, we noticed significant bradycardia in some patients immediately after administration of bolus doses of octreotide. Therefore, we investigated the effect of intravenous octreotide on systemic hemodynamics in 59 patients with cirrhosis. In two double-blind, placebo-controlled protocols, 32 patients received a 25-micrograms bolus and 20 patients received an infusion of 50-micrograms/hr of octreotide/placebo. Immediately after the bolus dose of octreotide was administered, there were significant reductions in pulse rate (77 +/- 3 vs. 65 +/- 3 beats per minute, P < .01) and cardiac output (9.2 +/- 0.8 vs. 7.9 +/- 0.8 L/min; P < .01) and significant increases in mean arterial pressure (81 +/- 3 vs. 87 +/- 3 mm Hg; P < .05), mean pulmonary artery pressure (9.1 +/- 1.0 vs. 16.6 +/- 1.5 mm Hg; P < .01), right atrial pressure (3.8 +/- 0.8 vs. 6.6 +/- 1.0 mm Hg; P < .01), right ventricular pressure (7.1 +/- 0.6 vs. 12.5 +/- 1.3 mm Hg; P < .01), pulmonary capillary wedge pressure (4.8 +/- 0.8 vs. 11.2 +/- 1.4 mm Hg; P < .01), systemic vascular resistance, and pulmonary vascular resistance. Thirty minutes after the start of the infusion, there were significant increases in mean right atrial pressure, right ventricular pressure, pulmonary artery pressure, and pulmonary capillary wedge pressure. This study suggests that intravenous octreotide has significant effects on the systemic circulation in patients with cirrhosis and that these effects appear to be more marked after administration of bolus doses.
