Hemodynamic Changes During the Anhepatic Phase in Pediatric Patient With Biliary Atresia Versus Glycogen Storage Disease Undergoing Living Donor Liver Transplantation

Abstract

ObjectiveThe aim of this study was to compare the hemodynamic changes caused by clamping of the inferior vena cava and portal vein in biliary atresia (BA) versus glycogen storage disease (GSD) patients undergoing living-donor liver transplantation (LDLT) without venovenous bypass. MethodsWe reviewed retrospectively the anesthesia charts of pediatric LDLT patients. Age, weight, height, blood loss, blood product use and fluid replacement between groups were compared with Mann-Whitney test, and systolic blood pressure (SBP), heart rate (HR), central venous pressure (CVP) before clamping of the inferior vena cava, and 4 measurements during anhepatic phase and 5 minutes after reperfusion were compared with analysis of variance. ResultsOne hundred four BA patients (GI) and 12 GSD patients (GII) showed mean total blood loss among GI to be more than among GII, but the blood products and crystalloids infused during the operation were not significantly different. The changes of SBP, HR, and CVP after clamping of the IVC were significantly different between groups. CVP of GII was lower than GI, indicating that venous return among GII was more affected, subsequently showing lower SBP and higher HR. ConclusionsTotal clamping of the inferior vena cava resulted a greater decrease in CVP in GII with subsequently lower SBP and faster HR compared with GI.
