Abstract

Introduction: Fetal weight estimation, obtained from measured symphysis fundal height, is crucial for ensuring to safe maternal and childbirth care. It serves as a standard nursing practice in the labor room, contributing to the quality of nursing care.

Research objectives: To investigate the relationship between fetal weight estimation obtained symphysis fundal height and accurate fetal weight from mothers with normal delivery.

Research methodology: This descriptive retrospective study included 333 pregnant women with singleton pregnancies, with no complications, with a gestational age of 37-42 weeks, signs of true labor pain, who gave birth naturally, and delivered at the Yasothon Hospital’s labor room. The estimated fetal weight data from the computer program were collected from medical records between January and December 2021, and The Index of item objective congruence by three qualified experts was .72. Data were analyzed using Pearson's correlation statistics.

Results: The average gestational age of the sample group was 38.42 weeks (SD = 1.35), with an average fundal height of 30.91 centimeters (SD = 2.16). The estimated fetal weight based on measured symphysis fundal height had an average weight of 2,989.18 grams (SD = 385.68), and the average birth weight of neonates born was 3,073.32 grams (SD = 344.97). The estimated fetal weight based on measured symphysis fundal height was significantly correlated to accurate fetal weight in Yasothon Hospital at a moderate positive level, and this correlation was statistically significant (r= .481, p < .05).

Conclusions: The estimated fetal weight based on symphysis fundal height was significantly correlated to accurate fetal weight at a moderate positive level.

Implications: To apply Johnson's formula for estimating fetal weight, based on measured symphysis fundal height in the labor room unit and studying prospective research.
