Study Notes
Liver Functions
- The liver synthesizes vital proteins, including albumin, which plays a crucial role in detoxification and digestion.
- The liver produces bilirubin, a substance that supports detoxification and digestion.
- The liver breaks down hemoglobin as part of its detoxification and degradation function.
MARS System
- The primary function of the MARS membrane is to separate albumin-bound toxins from the blood.
- The patient's albumin is not in contact with the adsorbers in the MARS system to prevent albumin loss.
- The MARS system can remove albumin-bound toxins, including protein-bound toxins, via dialysis.
- The MARS adsorbers are distinguished from other components of the system by their ability to remove albumin-bound toxins.
- The MARS membrane is highly permeable for albumin-bound toxins but not for the albumin itself.
Hepatic Encephalopathy
- Stage 2 of hepatic encephalopathy is characterized by clear confusion and awakening in dizziness.
- The loss of performance in detoxification leads to hepatic encephalopathy.
- The failing liver's inability to respond to insulin and store glycogen can result in hypoglycemia.
FPSA System
- The FPSA system separates the patient's albumin loaded with toxins from the blood using fractionated plasma separation and adsorption.
ADVOS System
- The albumin in the dialysate is cleaned in the ADVOS system.
Prometheus System
- The second adsorber in the Prometheus system removes toxins from the dialysate's albumin.
- The Prometheus system uses a membrane that also lets water-soluble toxins pass for removal via dialysis.
Adsorption
- Adsorption is different from absorption, as it involves the attraction of molecules to a surface.
- The affinity of toxins to bind to albumin is decreased in fluids with shifted pH values.
- Activated carbon is used in adsorption to attract toxins.
- The Vroman effect characterizes the adsorption of molecules to a surface.
