Correlation between Mode of Delivery and Newborn’s Cord Blood Composition

摘要

OBJECTIVE: The aim of this study is to find out the effect of delivery mode on newborn’s cord blood parameters particularly hemoglobin and hematocrite values. SETTING: Obstetrics and Gynecology Department, Qena Faculty of Medicine, South Valley University, Egypt. DURATION: From April 2015 to December 2017. STUDY DESIGN: A cross sectional study. METHODS: 900 live born neonates for healthy mothers were included in this study;all cases were delivered at full-term, with birth weight ranged from 2.5 to 3.5 Kg and had APGAR scores above 7 at 1 and 5 minutes. Newborns were divided into three groups (Group I included 300 newborns delivered by vaginal delivery without augmentation of labor, Group II included 300 newborns delivered vaginally with augmentation of labor and Group III included 300 newborns delivered by elective cesarean section). Blood sample was collected from the umbilical vein of each neonate for estimation of hemoglobin, hematocrit, RBCs count, platelets, WBCs count and reticulocytes. RESULTS: Cesarean section delivery had a statistically significant decrease in the level of iron-related hematologic indices including hemoglobin, hematocrit and RBCs count (p value 0.05). CONCLUSIONS: Cesarean section delivery had a significant decrease in the level of iron-related hematologic indices including hemoglobin, hematocrit and RBCs count and has a non-significant decrease in WBCs and platelets counts in neonatal cord blood, which suggest high prevalence of newborn iron-deficiency anemia among cesarean births particularly in developing communities.
