Comparison of Fundal Height Measurement and Ultrasonography for Estimation of Gestational Age

Abstract

Introduction: Estimation of gestational age is an essential component of prenatal care. Gestational age is estimated by Last Menopausal Period, fundal height and ultrasonography. Serial measurment of fundal height and comparison with LMP predicts the G.A more accurately. Since nowadays, ultrasonography is used more frequently during pregnancy, patients have to bear more expenses. But we can use serial measurement of fundal height for determination of G.A. This method is cheap, reliable and easy for assessment of G.A and fetal growth in pregnancies without serious complications. In this study, we compared the accuracy of Fundal Height Measurement And Ultrasonography for estimation of gestational age. Methods: In this cross sectional study we investigated and compared the accuracy of fundal height measurement and ultrasonography in estimation of G.A. A total of 140 pregnant mothers were selected from patients referring to gynecology and obstetrics clinic of Doctor Mojibian and Shahid Sadughi hospitals in Yazd. Gestational age of these patients were estimated two times; measurement of fundal height and ultrasonography. Collected data was analyzed with SPSS11.5 program and Pearson correllation statistical test. Results: This pregnant mothers were identified by some criteria. In these mothers, the G.A was estimated by ultrasonography (BPD,FL) and measurement of fundal height at G.A of 22-25 weeks, 22-25 weeks, and then at G.A of 25 to 28 weeks. Conclusion: The results showed that measurement of fundal height like sonography has a high a high rate of accuracy for estimation of G.A.
