METHOD FOR PREDICTION OF RISK OF HYPOXIC-ISCHEMIC CENTRAL NERVOUS SYSTEM IMPAIRMENT IN FULL-TERM NEWBORNS IN CASE OF LABOUR INDUCTION APPLIED Russian patent published in 2011 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, and can be used in obstetric practice, namely for predicting a risk of hypoxic-ischemic CNS impairment in full-term newborns in case of labour induction applied. That is ensured by studying obstetrical history, specifying a patient's age and labour parity. It is combined with foetal ultrasonography to determine a foetal weight, the presence of intrauterine growth retardation, an amount of amniotic fluid, probability of cord entanglement. It is followed with Fisher estimator cardiotocography. The following intranatal factors are considered before prescribing labour induction, including: labour pains beginning of parturition, amniotic fluid nature, parturition length, latency period length, carrying out of early amniotomy, carrying out of long epidural anaesthesia, probability of labour induction over four hours, probability of oxytocia. The obtained data are used to calculate a prognostic index F by formula: F=0.00037×X1+0.99606×X2+3.55949×X3+2.86668×X4+1.56860×X5- 0.34362×X6-1.64193×X7-1.92671×X8+0.00246×X9- 0.00283×X10+1.20945×X11+1.37799×X12+2.31317×X13+0.17955×X14- 0.20411×X15+0.05717×X16-0.71937×X17-2.22307.

EFFECT: method allows to predict a newborn's state, namely a perinatal CNS impairment, and to optimise an obstetric approach.
