title: [Perinatal morbimortality associated with placental senescence].
abstract: This is a prospective study in order to evaluate the association between placenta grade III changes and the neonatal outcome. A total of 370 patients divided into two groups were included: the case group included 182 patients with placenta grade III changes (placental senescence) and the control group included 188 cases with grade 0, I or II placenta. The patients with grade III placenta had more cases of oligohydramnios (37 vs 24%), cardiotocographic non reactive tests (35 vs 17 cases) and an elevated frequency of cesarean sections (83%), (P < 0.05). The newborns in both groups had not difference in birth weight and Apgar scores, but the senescence placental group had a higher incidence of meconium stained fluid (13 vs 8%, P < 0.05) and an increased admissions to special care nursery (17 vs 5 cases, P < 0.05). We concluded that our findings support that the placental senescence had a close association with the perinatal morbidity and we suggested a closer surveillance in these patients to improve the perinatal outcome.
