Background And AimThe hemodynamics of patients with portal hypertension within 4 h after a single injection of terlipressin has been studied. However, the hemodynamics in a longer phase under different infusion styles is unknown. This study aims to compare the effects of bolus and continuous infusion of terlipressin on systemic and hepatic hemodynamics in patients with portal hypertension.MethodsTwenty patients who underwent transjugular intrahepatic portosystemic shunt procedure were randomly assigned to be treated with either intravenous bolus infusion of terlipressin (1 mg) followed by a continuous infusion (4 mg/24 h, n = 10), or intravenous bolus injection of terlipressin (2 mg) followed by intermittent injections (1 mg/6 h, n = 10). The mean arterial pressure, heart rate, and portal venous pressure (PVP) were monitored and recorded at baseline, 1 min, 5 min, 10 min, 30 min, and then once an hour. Serum renin activity, serum angiotensin II, and aldosterone levels were measured prior to and 24 h after the administration of terlipressin.ResultsPVP dropped rapidly in both groups, and reduced 16.46% and 28.22%, respectively, at the 1-h time point. Thereafter, PVP remained stable in continuous group while rebounded obviously in intermittent group. One hour after the start of drug administration, heart rate decreased significantly in both groups (84.1 ± 12.8 vs 73.8 ± 12.6 in intermittent group and 86.7 ± 11.5 vs 77.1 ± 13.6 in continuous group, P < 0.005), and mean arterial pressure increased in both groups, although no statistical differences were found.ConclusionContinuous infusion of terlipressin reduces PVP stably and may become an alternative to traditional bolus injection.© 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.
