Summary
Liver transplantation causes significant hemodynamic and coagulation changes during reperfusion. Close monitoring and prompt interventions are crucial for patient stability and successful outcomes in liver transplant recipients.
Area of Science:
- Transplantation Surgery
- Anesthesiology
- Hepatology
Background:
- Liver transplantation is a complex procedure with significant physiological challenges.
- Intraoperative management requires careful attention to hemodynamic and metabolic status.
Purpose of the Study:
- To analyze intraoperative hemodynamic, laboratory, and coagulation data during liver transplantation.
- To identify key physiological changes and complications associated with donor liver reperfusion.
Main Methods:
- Retrospective analysis of data from the first 83 initial liver transplant patients.
- Inclusion of intraoperative hemodynamic, laboratory, and coagulation parameters.
- Assessment of thromboelastographic values.
Main Results:
- Significant hemodynamic shifts observed at reperfusion, including decreased blood pressure and increased cardiac output.
- Laboratory values indicated therapeutic interventions and potential citrate toxicity.
- Coagulopathy manifested as decreased fibrinogen and prolonged clotting times (prothrombin time, activated partial thromboplastin time).
Conclusions:
- Donor liver reperfusion triggers substantial hemodynamic instability and coagulopathy.
- Aggressive monitoring and timely interventions are essential for managing these changes.
- Maintaining hemodynamic and metabolic homeostasis is critical for liver transplant success.
