Study of Relationship between Placental Thickness and Fetal Weight using Ultrasonography

Abstract

This is across sectional descriptive study aimed to study the relationship between the placental thickness and fetal weight using ultra sonography in normal pregnancy women in Gable Awlia health center. Manual examination of the maternal abdomen was the only approach that could be used to estimate fetal size before the availability of ultrasound, physical examination however provides only a general approximation of fetal weight because the palpated dimensions of the uterus are affected by several factors other than fetal size, including amniotic fluid volume , placental bulk , presence of fibroids, and maternal obesity. The data collected in Om other health center from March 2020 to September 2020 .Hundred pregnant women in third trimester were scanned by Mindary ultrasound machine 3.5 mhz curve linear probe used, study by patient supine. Fetal weight was estimated by measurement of femer length(FL), biparietal diameter (BPD) and abdominal circumference (AC). Placenta thickness was measured in alongitudinal section at the point of insertion of the umbilical cord. The data is analyzed by using Package Statistical for Social Sciences (SPSS). Results of the study showed that there is strong positive correlation between placenta thickness and estimated fetal weight (r=0.713) and (p=0.05) and both are firmly increase with fetal age .The results also showed linear regression between them. Study showed that the fetal weight increase by 60 gm/mm of the placenta thickness. Researcher noticed that with same placenta thickness there were different fetal weights. However, the normality of fetal weight and fetal development can followed by measuring Placental thickness. Study recommended that further studies should be done with the increasing number of sample and introduced Doppler U/S and follows the fetal weight by placental thickness measuring and fetal weights the same fetus in first and second trimester and after delivery.
