METHOD FOR POSTNATAL PERSISTENCE OF HAEMODYNAMICALLY SIGNIFICANT OPEN ARTERIAL DUCT IN PREMATURE INFANTS Russian patent published in 2015 - IPC A61B5/02 

FIELD: medicine.

SUBSTANCE: clinical, X-ray and echocardiographic examinations are performed in a premature infant on the third day of life. Gestation age, Apgar score, infant's reflexes, states of the muscular system, skin, oedemas, moist rale, increased pulmonary vascularity on the X-ray pattern, as well as echocardiographic values of final diastolic size, left atrium and right ventricle per one kilogram of infant's body weight are assessed, and a prognostic coefficient is determined by mathematical formula. If the prognostic coefficient is 10 points and more, the high risk of long persistence of a haemodynamically significant form of the open arterial duct in the premature infants is predicted; the prognostic coefficient falling within the range of 0 to 9 points shows the low risk of long persistence of the haemodynamically significant form of the open arterial duct.

EFFECT: method enables predicting the non-invasive prediction of the high risk of long persistence of the haemodynamically significant form of the open arterial duct in the premature infants on the third day of life, and specifying the further therapeutic approach to the infant and the absolute indications for persistent foetal communication correction.
