[Clinical and biological significance of arterial blood ketone body ratio in hepatic surgery]. 1983

K Ozawa

In a recent study from our laboratory, 372 patients were classified into 4 groups according to the postoperative changes in the arterial blood ketone body ratio: Group A without decrease below 0.7 (greater than 0.7 in control), Group B with transient decrease to 0.4, Group C with progressive decrease to below 0.4, and Group D, the terminal stage, with decrease to below 0.25. Groups A and B patients tolerated operation well. In the 28 Group C patients, 24 of them died of multiple organ failure. The metabolic liver support designed by us (an ex vivo pig or baboon liver cross-hemodialysis with an interposed cuprophan membrane) has been applied for the patients with both blood ketone body ratio below 0.4 and grade IV hepatic coma. All Group C patients became fully alert after liver support concomitant with the restoration of the blood ketone body ratio. By contrast, in Group D patients, there was no restoration of consciousness and no improvement in their blood ketone body ratios by this liver support. It has been suggested that blood ketone body ratio level serves as an excellent indicator of the deranged metabolic process and mortality in critically ill patients.

UI	MeSH Term	Description	Entries
D007657	Ketone Bodies	The metabolic substances ACETONE; 3-HYDROXYBUTYRIC ACID; and acetoacetic acid (ACETOACETATES). They are produced in the liver and kidney during FATTY ACIDS oxidation and used as a source of energy by the heart, muscle and brain.	Acetone Bodies,Bodies, Acetone,Bodies, Ketone
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008107	Liver Diseases	Pathological processes of the LIVER.	Liver Dysfunction,Disease, Liver,Diseases, Liver,Dysfunction, Liver,Dysfunctions, Liver,Liver Disease,Liver Dysfunctions
D008930	Mitochondria, Liver	Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.
