METHOD FOR PREDICTING SEROUS MENINGITIS OUTCOMES IN CHILDREN Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves making lumbar puncture and measuring liquor pressure, taking pleocytosis into account, making ultrasonic transcranial Doppler flowmetric examination of brain, determining linear blood circulation speed on interior carotid artery and posterior cerebral artery, detecting intracranial venous discharge disorders through orbital and vertebral veins. Regression coefficient is calculated from a formula

where X1 is patient age (in years); X2 is the pleocytosis in the first lumbar sample (in cells number per 1 mcl of liquor); X3 is the meningitis symptoms duration (in days); X4 is the focal symptoms availability (1- yes, 0- no); X5 is the general cerebral symptoms duration (in days); X6 is the liquor pressure when taking the first lumbar puncture (in mm of mercury column); X7 is the linear blood circulation speed in interior carotid artery (in Hz/s); X8 is the linear blood circulation speed in posterior cerebral artery (in Hz/s); X9 is the intracranial venous discharge disorders based on ultrasonic transcranial Doppler flowmetric examination data; retrograde discharge through orbital veins, increased one through vertebral veins and others (1- yes, 0- no). Value of y≤0.5, unfavorable outcome is to be predicted with cerebroasthenic, asthenoneurotic and hypertension syndromes being formed. If y>0.5, favorable infectious process outcome is to be predicted.

EFFECT: high accuracy of diagnosis.
