Albumin effect on hemorheological parameters in patients with liver transplant.
Background: Liver transplantation is a life-saving treatment in end-stage liver failure. Hemorheological features as blood fluidity and red blood cell aggregation may alter effective tissue perfusion, graft function and hemodynamic variables.
Objective: The aim of the study is to investigate effect of albumin infusion on red blood cell deformability and aggregation, blood viscosity and hemodynamics in liver transplant patients.
Methods: Seventeen live or cadaveric donors were included in this prospective study. Hemorheological and hemodynamic measurements were performed in order to evaluate the effects of albumin infusion in perioperative period.
Results: Erythrocyte aggregation was significantly reduced 90 minutes after albumin infusion (p < 0.01). Mean blood viscosity revealed significant decrease at 20 rpm and 50 rpm after 90 minutes of albumin infusion (p < 0.05). Plasma viscosity decreased significantly compared to the value before albumin infusion at 20 rpm (p < 0.05). Albumin replacement improved hemodynamic variables in patients with low blood pressure and cardiac index measurements (p > 0.05).
Conclusions: Human albumin infusion led to decrease in whole blood and plasma viscosities, red blood cell aggregation and induced blood pressure and cardiac index elevation in perioperative liver transplant patients. Determination of hemodynamic and hemorheological effects of human albumin replacement in various patient populations may serve beneficial clinical data.
期刊介绍：
Clinical Hemorheology and Microcirculation, a peer-reviewed international scientific journal, serves as an aid to understanding the flow properties of blood and the relationship to normal and abnormal physiology. The rapidly expanding science of hemorheology concerns blood, its components and the blood vessels with which blood interacts. It includes perihemorheology, i.e., the rheology of fluid and structures in the perivascular and interstitial spaces as well as the lymphatic system. The clinical aspects include pathogenesis, symptomatology and diagnostic methods, and the fields of prophylaxis and therapy in all branches of medicine and surgery, pharmacology and drug research.
The endeavour of the Editors-in-Chief and publishers of Clinical Hemorheology and Microcirculation is to bring together contributions from those working in various fields related to blood flow all over the world. The editors of Clinical Hemorheology and Microcirculation are from those countries in Europe, Asia, Australia and America where appreciable work in clinical hemorheology and microcirculation is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Clinical Hemorheology and Microcirculation accepts original papers, brief communications, mini-reports and letters to the Editors-in-Chief. Review articles, providing general views and new insights into related subjects, are regularly invited by the Editors-in-Chief. Proceedings of international and national conferences on clinical hemorheology (in original form or as abstracts) complete the range of editorial features.
