title: [Plasma concentration of atrial natriuretic peptide, vasopressin and aldosterone in the umbilical cord blood: its relation to perinatal asphyxia].
abstract: Aldosterone, vasopressin (AVP) and atrial natriuretic factor (ANF) plasmatic concentrations were determined in cord arterial blood from 42 newborns to term: 29 healthful and 13 with perinatal asphyxia. Control group showed plasmatic levels (pg/dl) AVP, aldosterone and ANF significantly lower than perinatal asphyxia newborns group (AVP: 2.27 +/- 1.43 vs 4.26 +/- 2.86; aldosterone: 1.113 +/- 384.79 vs 1,540.38 +/- 595.96; ANF: 2.27 +/- 1.43 vs 4.26 +/- 2.86, respectively (p less than 0.05). We found an inverse correlation between umbilical arterial pH vs AVP, aldosterone and AFN, and a direct correlation between ANF vs aldosterone. Perinatal asphyxia induces secretion of the three studied hormonal factors, likely as a physiologic mechanism of fetal adaptation to hydroelectrolytic and hemodynamic changes which occur during the asphyxia.
