Observational Study
Assessment of standard laboratory tests and rotational thromboelastometry for the prediction of postoperative bleeding in liver transplantation.
Perioperative bleeding remains a major challenge in liver transplantation. We aimed to compare standard laboratory tests with thromboelastometry (ROTEM ® ) with regard to their ability to predict postoperative non-surgical bleeding. ⋯ Although both postoperative standard laboratory tests and ROTEM ® assays could identify patients at risk for postoperative bleeding, ROTEM ® assays demonstrated a greater predictive value for impaired fibrinogen polymerization-related coagulopathy.

Previous work suggests that anaesthesia and surgery amplify the pathology and cognitive impairment of animals made vulnerable via age or specific transgenes. We hypothesized that surgery under propofol anaesthesia, a widely used i.v. general anaesthetic, has minimal delayed cognitive and neuroinflammatory sequelae in a vulnerable mouse transgenic model. ⋯ Surgery in a vulnerable transgenic mouse under propofol anaesthesia was associated with minimal to no changes in short- and long-term behaviour and no changes in neuropathology. This suggests that propofol anaesthesia is associated with better cognitive outcomes in the aged, vulnerable brain compared with inhalation anaesthesia.
