Estimation of Fetal Birth Weight - การคาดคะเนน้ำหนักทารกในครรภ์

บทคัดย่อ

                       The objective of this descriptive study was to develop the regression model to estimate fetal birth weight.  The study was carried out during October 1st, 2005 to November 30th, 2005 in 100 pregnant women who had intact amniotic membrane and delivered in Nong Khai hospital within 48 hours of labor.  This study focused on six maternal variables : maternal weights before pregnancy and at the admission dates, gestational age, uterine fundal height (FH), abdominal circumference at umbilical level (AC) and fetal head station.  The data was analysed by multiple stepwise regression analysis. Only uterine fundal height (FH) and abdominal circumference (AC) showed significant correlation with fetal birth weight (p = 0.05) The model then, became Birth weight (grams) = - 2771.57+80.27FH+32.85 AC where : R = 0.820, Adjusled R2 = 0.664, standard error of estimation is 270.32 grams
