DIAZ SALAZAR, Mardorys et al. Assessing the Effectiveness of Ultrasound in Predicting Birth Weight in High-Risk Pregnant Women. Salus [online]. 2011, vol.15, n.3, pp.13-18. ISSN 1316-7138.

Globally there are studies on the effectiveness of ultrasound in predicting birth weight infant, but some authors question the validity of the technique of calculation of fetal weight by ultrasound. Coupled with our patients are high risk. (4), based on this arises: Assessing the Effectiveness of Ultrasound in Predicting Birth Weight in High-Risk Pregnant Women attending Perinatology CHET in the period January to September 2009 of which A sample circumstantial and not random volunteer subjects comprising 305 patients whose inclusion criteria were pregnancies after 22 weeks of gestation with no fetal malformations and had an ultrasound prior to delivery or caesarean section less than or equal to 15 days. The pathology score was the most common obstetric preterm labor 7.9% and medical diseases with obesity 43.6%, finding statistically significant P <0.0001 between the restriction intrauterine growth with obesity, hypertension during pregnancy and oligohydramnios, and the big fetus for gestational age with gestational diabetes. The weight difference was obtained between the calculated and obtained by ultrasound at birth 108.76 grams with statistical association between two variables which was a positive linear with a correlation coefficient R2 = 0.710, P <0.0001 and a standard error of estimate of 387.76042. The linear regression equation for the variable of birth weight was: PN was ECOG Weight = 217.134 + x 0.096 days, error rate of 3.63%, explaining the ultrasound weight, 70.8% of the weight variation at birth.
