Indocyanine green disappearance enhanced by prostaglandin E1 in patients with hepatic resection.
Indocyanine green (ICG) is a reliable indicator reflecting hepatocyte function and hepatic blood flow. Prostaglandin E1 (PGE) has been indicated to increase hepatic blood flow and protect the hepatocyte. The purpose of this study is to investigate whether PGE influences the ICG disappearance rate in patients with hepatic resection. Eleven patients with hepatic resection were divided into two groups according to the presence of liver cirrhosis (LC, n = 4) and chronic hepatitis (CH, n = 7). ICG 0.1 mg/kg was given as an intravenous bolus into the cubital vein 5 min after PGE administration, then the disappearance rate of ICG (ICG-K) was determined by a finger monitoring method. PGE administration increased ICG-K in the LC and CH groups with normal liver function, and the ICG-K response was dose dependent when the dosage of PGE ranged from 0.01 to 0.05 microg/kg/min. When ICG-K relative to the ICG-K of the control was defined as the ICG-K ratio, the daily course of the ratio in the LC group was higher than in the CH group. PGE increases the ICG-K of patients with normal liver function before and after hepatic resection, and this is evident in the case of liver cirrhosis.
