    Abstract:
    The influence of SMS 201-995 (octreotide, Sandostatin), a long-acting somatostatin analogue, on splanchnic haemodynamics was studied in 15 patients with liver cirrhosis and in 5 healthy individuals before, during, and after 60 min of intravenous SMS infusion (25 and 50 micrograms/h, respectively). No adverse effects of the SMS infusion were seen. In the basal state the estimated hepatic blood flow was 1.04 +/- 0.08 l/min (mean +/- SE) in the patients and 1.62 +/- 0.09 l/min (P less than 0.001) in the controls. At 15 min after the beginning of the infusion the blood flow had already decreased by 15-30% (P less than 0.05-0.01). The reduction was more marked in controls than in patients, and it persisted in both groups during and for 60 min after the infusion. Wedged hepatic venous pressure, measured in the patients, was 20 +/- 2 mmHg in the basal state and 18 +/- 1 mmHg during the infusion (P less than 0.05), and it remained at this level for 60 min after the infusion. Free hepatic venous pressure was unchanged throughout the study. Splanchnic oxygen uptake was similar in the two groups in the basal state and remained unaltered during and after SMS infusion. Both heart rate and arterial systolic and diastolic blood pressure remained unchanged during SMS administration. In summary, SMS infusion results in a fall in hepatic blood flow and a slight but significant decrease in wedged hepatic venous pressure, whereas no effect was noted on the systemic circulation.(ABSTRACT TRUNCATED AT 250 WORDS)
