Abstract

Background: In an effort to ameliorate the adverse outcomes associated with traumatic delivery, maternity care professionals continue to search for methods of predicting fetal weight accurately. Aim: This study was designed to clarify the relation between cross sectional area of umbilical cord measured by ultrasound and actual birth weight and compare it with that of hadlock's formula. Patients and method This ; prospective cohort study included 113 pregnant women with uncomplicated, singleton pregnancy and gestational age of 37-42 weeks, admitted with early labor or prepared for elective cesarean section. All were examined by ultra sound, during which fetal anthropometric parameters (BPD, FL, and AC) and cross sectional area of umbilical cord were measured. The estimated fetal weight calculated by Hadlock's formula and by cross sectional area of umbilical cord was correlated with actual birth weight. Results: There was a significant moderate correlation between umbilical cross sectional area with, maternal BMI and neonatal gender, gestational age, but there was no correlation with maternal age, height and parity p.( <0,001) . The umbilical cord cross sectional area and Wharton’s jelly area were found to be moderately correlated with neonatal actual birth-weight, and no significant correlation with umbilical vessels area P (<0.001) The correlation strength of the umbilical cord cross sectional with the estimated birth weight was higher than that by Hadlock’s formula with the value of Coefficient of determinant (R2= 0.3828) for umbilical cord area versus (R20.194 ) for Hadlock's. Conclusion: The cross sectional area of umbilical cord was more accurate in predicting birth weight than fetal anthropometric parameters Bi parietal diameter, femur length and abdominal circumference, (BPD, FL,AC)by Hadlock's formula.

Abstract

Background: Iron is an essential micronutrient that plays a significant role in critical cellular functions in all organ systems in all species. Iron is particularly vital for early brain growth and function in humans since it supports neuronal and glial energy metabolism, neurotransmitter synthesis and myelination.Methods: 93 infants born through normal vaginal and cesarean delivery, enrolled in this study. According to maternal iron supplementation the sample divided in to two groups: iron supplemented group or a non-iron supplemented group. Women in the iron supplemented group consumed daily prenatal supplements. At the time of delivery, 5-ml of blood was obtained from the umbilical cord after early ligation of the cord, for each sample (Hb), (MCV), (RDW), (CBI) and (TIBC) was measured. Maternal age, Gestational age, parity birth weight, and baby sex were also recorded.Results: The mean of neonatal birth weight was higher in iron supplemented group (2589.29±638.74gm) than that in non- iron supplemented group (2150.94±601.48), (P<0.01). The Cord Blood Markers of the newborns (Hb, MCV ,CBI, TIBC) shows higher values in iron-supplemented group than that in non-iron supplemented group, (P<0.05). The cord blood markers of SGA newborns (Hb, MCV, CBI, TICB) were more than that in AGA newborns (P<0.01).Conclusions: Maternal iron supplementation during pregnancy significantly increases neonatal birth weight. Most the cord blood hematological markers of neonate have higher value in iron-supplemented mothers than that in non-iron supplemented mothers which indicated better iron status.

خلفية البحث: مادة الحديد هي احد المكونات الاساسية التي تلعب دورا مهما في الوظائف الخليوية الحرجة في اعضاء الجسم وعند كل الانواع .ان مادة الحديد لها دور حيوي في نمو وتطور وظائف الدماغ عند الانسان , حيث يدعم عملية التمثيل الغذائي في الخلية العصبية وكذلك يدعم المادة العصبية البيضاء بين مكوناتها .الطريقة :حوالي 93 رضيع ولدوا طبيعيا او عن طريق عملية قيصرية شملوا بهذه الدراسة . وطبقا لتزويد مادة الحديد للام فأن هؤلاء الامهات قسموا الى مجموعتان :مجموعة زودت بالحديد وأخرى لم تزود,حيث كانت المجموعة الاولى تؤخذ الحديد بشكل يومي قبل الولادة .وعند الولادة( 5مل)من الدم تسحب من الحبل السري الوريدي بعد عقده مباشرة ومن هذا النموذج ترسل تحليل الهيموكلوبين ,معدل حجم الخلية ,عرض الخلية الانتشاري , سعة مجموعة الحديد المرتبط , لغرض قياسها. كذلك تم تسجيل عمر الام, فترة الحمل, وزن الرضىع وجنسه .النتائج : لوحظ ان معدل وزن الرضيع كان اعلى عند الامهات التي زودت بالحديد اثناء فترة الحمل عن اللاتي لم يؤخذن الحديد60.48.± 2150,94 غم وان القيمة الاحتمالية هي اصغر من< 0.05 كما ان 638.47±±2598.29 مؤشرات تحليل الدم المأخوذ من الحبل السروي الوريدي للطفل الرضيع ( HB.MCV.CBI.TIBC ) اظهرت نتائج وقيم اعلى من اقرانهم الرضع عند الامهات التي لم تزود بالحديد وان القيمة الاحتمالية(< 0.05) .كذلك فأن مؤشرات القيم عند الرضع الخفيفي الاوزان (MCV.CBI.TIBC HB.)كانت اكثر من مثيلاتها عند الاطفال ذوو الاوزان الطبيعية حيث ان القيمة الاعتمادية هي( < 0.05)الاستنتاج: ان تزويد الامهات بالحديد اثناء فترة الحمل يزيد وزن الاطفال حديثي الولادة كما ان اغلب مؤشرات التحاليل الدموية في الحبل الوريدي عند الاطفال حديثي الولادة وجد ان نتائجها اعلى عند الامهات التي اخذن الحديد .
