INTRODUCTION: The aim of this study was to investigate the factors that influence intrapartum fetal weight estimation.
METHODS: A total of 173 pregnant women who were under follow-up at the Zeynep Kamil Maternity Hospital between May 2015 and April 2016 and who had singleton, live-term pregnancy between the gestational weeks of 37 and 42 with the head presentation were included in the study. Biometric measurements were made with ultrasonography. The amniotic fluid index (AFI) was measured and recorded. Newborn fetal weight measurements recorded in the birth registration book were compared with estimated fetal weight measurements. The effects of biometric measurements, AFI, gestational week, body mass index (BMI), engagement, and clinical experience on fetal weight estimation were compared.
RESULTS: A positive statistically significant association at the 32.3% level was determined between the birth weight and gestational week (p=0.001 and p<0.05). A positive statistically significant association at the 21.7% level was found between birth weight and BMI (p=0.004 and p<0.05). No statistically significant association was found between birth weight and BMI according to the presence of engagement (p=0.391 and p>0.05). When the professional seniority between physicians was evaluated, the rate of deviation from fetal weight was estimated to be 8.7%, and the difference was not found to be statistically significant (p>0.05).
DISCUSSION AND CONCLUSION: Gestational week and BMI were determined to be significant for deviation from estimated fetal weight and professional seniority differences; engagement and AFI were determined to be ineffective.
