Critical care apheresis: hepatic failure.
1University of Maryland, Baltimore, USA.
Summary
Hepatic failure is common in critical care, often managed medically. However, artificial organ support, including promising hybrid bioartificial liver devices, shows success in advanced liver failure cases, particularly as a bridge to transplant.
Area of Science:
- Critical care medicine
- Hepatology
- Biomedical engineering
Background:
- Hepatic failure is a frequent complication in intensive care units (ICUs).
- While medical management and metabolic support are primary treatments, the efficacy of extracorporeal organ support for hepatic failure is less established than for renal or pulmonary failure.
- Advanced liver failure presents significant therapeutic challenges.
Purpose of the Study:
- To review the current role and potential of extracorporeal organ support in managing hepatic failure.
- To highlight the advancements and promise of artificial liver support systems, particularly hybrid bioartificial liver substitutes.
Main Methods:
- Literature review and synthesis of existing research on hepatic failure management in critical care.
- Analysis of the application and outcomes of artificial organ support in advanced liver disease.
- Evaluation of the potential of bioartificial liver devices.
Main Results:
- Most hepatic dysfunction in the ICU is managed effectively through medical and metabolic interventions.
- Extracorporeal organ support for hepatic failure is not as well-defined as for other organ failures.
- Artificial organ support has demonstrated success in treating advanced liver failure.
Conclusions:
- Hybrid bioartificial liver substitutes represent a promising therapeutic option.
- These advanced devices show particular potential as a bridge to liver transplantation for patients with end-stage liver disease.
