Some Anatomical Changes in Placenta In Relation To Newborn`s Apgar score


Background: Sick newborns from apparently normal mothers, typically, have low Apgar scores and at such situation; there are great probabilities, for these newborns to develop several diseases, with poor outcomes. Also, there may be a chance for any prospect baby, to get same health state. Objective: This study was designed to correlate some of the placental topographic anatomical data with the newborn wellbeing, and to lay highlighting, on the presence of any placental abnormality, which could be caused by neither maternal nor fetal factors. Materials and methods: the study included 60 full term placentae of apparently normal mothers, who were admitted to Labor Room at al-Yarmook Teaching Hospital, al-Elwia Maternity Teaching Hospital and al- Khadhra`a Private Hospital, in Baghdad, for a normal vaginal delivery, or even for a caesarian section. The research was done over the period of 1stof February 2013 till end of 15thof April 2013. The newborns were scored high and low in Apgar score. The following anatomical data were selected in this study: the placental weight /newborn weight ratio, the mode of the umbilical cord insertion and the placental thickness, in each of the low and high Apgar score groups of fetuses, as indicators for the functional status of the placenta in these two groups. Results: The placental/newborn weight ratio in low Apgar score group of fetuses, was significantly lower than that in the high Apgar score ones. As regarding the umbilical cord mode of insertion; the eccentric type of insertion was more in both of fetal groups, nevertheless it was relatively higher in the high Apgar score group of fetuses, while the central type was more in the low Apgar score group of fetuses. The marginal type was only seen at the low Apgar score group of fetuses. The mean of thickness of placentae of low Apgar score group, was found to be less than that of the high Apgar score group, Conclusions: There was a strong and significant correlation between the fetal well being and data obtained from these topographic anatomical placental records.
