Diagnosis of brain and kidneys hemodynamic disorders in newborn with hipoxic encephalopathy

Abstract

Diagnostic criteria of angiospastic disorders and decreased blood flow in the brain and kidneys in neonates with hypoxic-ischemic and hypoxic-traumatic encephalopathy in 5-14 days are established: basilar artery RI ≥ 0.68 (sensitivity (Se) 83.8 %, specificity (Sp) 92.9 %, likelihood ratio (LR) 11.7), anterior cerebral artery RI ≥ 0.67 (Se 81.0 %, Sp 92.3 %, LR 10.5), middle cerebral artery RI ≥ 0.66 (right Se 77.5 %, Sp 92.3 %, LR 10.1; left Se 77.5 %, Sp 92.3 %, LR 10.1); stem renal artery RI ≥ 0.74 (right Se 70.2 %, Sp 88.9 %, LR 6.3; left Se 72.3 %, Sp 88.9 %, LR 6.5), segmental branches of the renal artery RI ≥ 0.70 (right Se 61.7 %, Sp 77.8 %, LR 2.8; left Se 70.2 %, Sp 83.3 %, LR 4.2), interlobar branches of the renal artery RI ≥ 0.62 (right Se 70.2 %, Sp 77.8 %, LR 3.2; left Se 70.2 %, Sp 72.2 %, LR 2.5).
