“…1 Most of the studies show that about 75% of the estimates are within 10% of the actual weight. 3,13,14 But in our study, only 60% estimates were within 10% of the actual weight which is similar to the other study. 2,15 Ultrasound underestimated the actual weight in 36.67% of cases and overestimate 56% of cases.…”

“…This has increased the accuracy of the fetal weight estimation significantly. 2,3 Multiple formulae have been developed for the estimation for birth weight using ultrasound measurement. [4][5][6][7][8][9][10] At present, fetal ultrasound is extensively used to estimate the fetal weight.…”

Comparison between Three Methods of Fetal Weight Estimation during the Active Stage of Labor Performed by Residents: A Prospective Cohort Study

et al. 2016

Objective: To compare the accuracy of ultrasonographic, calculated, and clinical methods for the estimation of fetal weight (EFW) performed during active labor by residents. Methods: Parturients in active labor underwent prospectively EFW by 3 methods: ultrasonographic, clinical, and calculated (extrapolating EFW from a previous scan). Three different blinded residents evaluated each woman. Background variables were examined for their effect on the accuracy of each method. Comparison of the methods for the detection of macrosomia and small for gestational age (SGA) was also performed. Results: Among the 405 women recruited, the rates of accuracy of ultrasonographic, clinical, and calculated EFW (within ±10%) was 72.5, 74.3, and 71.1%, respectively. The correlation coefficient between the methods and actual birth weight (ABW) were 0.702-0.611 (using 7 Hadlock formulas), 0.649, and 0.622, respectively (all p < 0.001). By logistic regression, epidural analgesia was associated with higher and second stage of labor with lower accuracy of ultrasonographic EFW. For the detection of macrosomia, clinical (p < 0.001) and calculated EFWs (p = 0.035) were superior to ultrasonographic EFW. For the detection of SGA, ultrasonographic EFW was superior to calculated (p < 0.001) and clinical (p < 0.001) EFWs. Conclusion: All 3 methods performed by residents during labor correlated well with ABW. Clinical and calculated EFWs were superior for macrosomia detection, whereas ultrasonographic EFW was superior for SGA detection.

“…In term gestations, it appears that intrapartum estimation of fetal weight by ultrasound is more accurate than maternal perception or clinical estimation by resident or attending physicians [3]. However, the obstetrical literature is replete with articles showing that neither clinical estimation nor estimation of fetal weight by ultrasound is accurate in diagnosing fetal macrosomia (actual birth weight 44000 g) [4][5][6][7][8][9][10][11][12].…”

Ultrasound machines are nowadays part of the armamentarium of all modern Labor and Delivery Suites. Due to their portability, these machines are ideal for use in emergencies which can occur at any of the labor and delivery rooms. Many of the emergencies in Labor and Delivery can be life threatening; thus, maternal and fetal safety requires efficient and timely ultrasound evaluation. The purpose of this article is to provide guidelines for quick and efficient use of ultrasound based on both the authors' experience and the published literature.
