METHOD OF PRE-OPERATION DIAGNOSTICS OF HEPATIC FAILURE IN PATIENTS WITH OBSTRUCTIVE JAUNDICE Russian patent published in 2013 - IPC A61B10/00 G01N33/48 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to surgery. To carry out pre-operation diagnostics of hepatic failure in patients with obstructive jaundice, examination of patient is performed. Acetic, propionic, butyric and isovaleric acids are identified in blood by gas chromatography method. Level of citrulline in blood is determined by method of colorimetry. If concentration of acetic acid is within the range from 0.4258 to 1.1000 mmol/l, that of propionic acid is higher than 0.0214 to 0.0970 mmol/l, of butyric acid higher than 0.003 to 0.009 mmol/l, of isovaleric acid higher than 0.00004 to 0.003 mmol/l, and if level of citrulline is in the range from 27.3±12.36 to 31.5±11.03 mmol/l, hepatic failure is diagnosed.

EFFECT: method makes it possible to diagnose hepatic failure in patients with obstructive jaundice before operation.
