Investigation of Systemic and Regional Haemostasis During Liver Transplantation by Comparing ClotPro® and TEG®

"Systemic sampling is performed six times:~* before the surgery (S1)~* during the hepatectomy, 10 minutes before the anhepatic phase (S2)~* in the anhepatic phase, before starting portal vein anastomosis: (S3)~* in the neohepatic phase, 15 minutes after releasing portal vein clamping: (S4)~* in the neohepatic phase, at the end of the surgery: (S5)~Regional sampling from the portal vein representing afferent flow to the liver is performed once:~• in the anhepatic phase, before starting portal vein anastomosis: (R)~Simultaneously with haemostasis and blood gas analyses, the following investigations will be performed (the following tests are also routinely performed at the given time points, independently of this study):~* haemodynamic measurements by PiCCO~* arterial blood gas analysis from radial artery catheter~* central venous blood gas analysis from subclavian vein catheter~* blood temperature measurement in the femoral artery by PiCCO catheter~* hourly urinary output"
