摘要
A method for defining the tactics of correcting the open arterial duct in premature newborns with critical body mass provides for sonography of heart estimating the diameter of the open arterial duct, the direction of blood by-passing via the open arterial duct, calculating aorta / left atrium ratio and Doppler study in the anterior cerebral and major renal arteries with calculation of resistance index (R). The following parameters are measured: the end-diastolic size of the left ventricle (cm), the end-diastolic volume of the left ventricle (mL), the anatomical size of the aortic root at the level of valvular ring, and the transverse dimension of the left atrium. The following blood circulation parameters are calculated: systolic rate of blood flow V, diastolic rate of blood flow Vin the anterior cerebral and major renal arteries. In addition, the decreased diuresis rate, the systemic arterial blood pressure and the increased level of the nitrogenous waste are assessed. When the diameter of the open arterial duct exceeds , the left-to-right by-passing pattern via the open arterial duct is evident, the end-diastolic size of the left ventricle exceeds , the end-diastolic volume of the left ventricle exceeds 5 mL, aorta / left atrium ratio exceeds 1.3/1; Vin the anterior cerebral and the major renal arteries exceeds 20.5 cm/s, Vin the anterior cerebral artery or one of the major renal arteries is less than 3.0 cm/s, Rin the anterior cerebral artery or one of the major renal arteries exceeds 0.94, the systemic systolic arterial blood pressure decreases to less than Hg, the systemic diastolic arterial blood pressure decreases to less than Hg, the diuresis rate in less than 1 mL/kg/h, urea content increases over 10 mmol/L, creatinine 140 µmol/L, the bypassing of blood via the open arterial duct should be immediately terminated surgically. In such setting, the intravenous inhibitors of prostaglandins are contraindicated.
