Summary
Continuous monitoring of total oxygen consumption (VO2) during liver transplantation can detect early changes in graft function. This method helps identify critical phases and potential complications, improving patient outcomes.
Area of Science:
- Hepatology and Transplant Surgery
- Physiological Monitoring
- Medical Device Technology
Context:
- Liver transplantation is a vital treatment for end-stage liver disease.
- Primary non-function (PNF) of the liver graft is a significant post-transplant complication.
- Early intraoperative assessment of graft function is crucial for successful outcomes.
Purpose:
- To evaluate continuous total oxygen consumption (VO2) monitoring using the PhysioFlex anesthesia device for early detection of graft dysfunction during liver transplantation.
- To investigate the correlation between intraoperative VO2, ischemic times, and postoperative liver function in 51 liver transplant recipients.
Summary:
- Continuous VO2 monitoring accurately indicated anhepatic and neohepatic phases.
- Changes in VO2 correlated with early graft metabolism issues and transient postoperative liver dysfunction.
- No primary non-function (PNF) was observed; VO2 correlated with postoperative bilirubin levels.
Impact:
- Continuous VO2 monitoring offers a promising tool for real-time assessment of liver graft viability during transplantation.
- This technology can aid in the early detection of metabolic changes and critical intraoperative phases.
- Further refinement, including averaging VO2 values, may enhance its routine clinical utility.
