Prediction Of Gestational Age Using Humeral Length In Third Trimester Using Ultrasonography

Abstract

This is analytic study was carried out in Alturki teaching hospital in ultrasound department in period between of September 2018 to December 2018.the study population 70 singleton pregnancy ,healthy pregnant women, whom sure of their LMP.also fetus must be free of congenital anomalies. The study sample was selected randomly from pregnant women whom came to antenatal care ,GA by LMP and by FL were calculated. the proplem was delivered from inability to asses GA by head biometery in fetus whom engaged and had congenital head disease. The aim of this study was to predict GA by using HL. The measurement was done by ultrasound machine SONACE X6.The data was collected by data sheet ,which contained maternal age ,gravidity, LMP,FL,HL GA by LMP and GA by FL. then the analysed by SSPS, The result revealed that there was significant correlation noticed between GA by LMP and length of both FL(.811) and HL(.902). also there was significant correlation between GA by FL and HL(.884). The study recommended that the humeral length must be used as measurement in calculation of GA in third trimester, also numbers of sample should be increased in further study.
