Abstract:

 Aims: To identify factors influencing the accuracy of estimated fetal weight in small for gestational age SGA fetuses. Methods: This retrospective cohort study included 268 women in the third trimester with singleton pregnancies and estimated fetal weight below the 10th percentile. Data were obtained from electronic medical records, and the Hadlock formula was used to estimate fetal weight through ultrasound measurements. Patients with fetal growth restriction due to placental insufficiency, preeclampsia, multiple pregnancies, or fetal anomalies were excluded from the study. The study groups were categorized based on differences between their estimated and actual birth weights. Results: The analysis showed that 24.3 of the cases had a difference of 10 between estimated and actual birth weights. The mode of delivery was significantly associated with weight difference, with a lower cesarean section rate in the group with a difference 10. There were no significant differences in clinical and sonographic characteristics between the study groups. Perinatal outcomes did not exhibit significant differences in gestational age at delivery, delivery mode, sex, or meconium-stained amniotic fluid. However, there was a significant difference in birth weight, with higher birth weights observed in the group with a difference 10. Logistic regression analysis did not reveal any statistically significant associations between the examined factors and weight differences 10. Conclusion: This study highlights the challenges of accurately estimating fetal weight in SGA fetuses. Further research is needed to identify additional factors and develop more reliable methods for estimating fetal weight in these cases, aiming to improve prenatal management and reduce the risk of adverse outcomes.

 Amaç Gebelik yaşına göre küçük SGA fetüslerde tahmini fetal ağırlığın doğruluğunu etkileyen faktörleri belirlemek. Çalışma Tasarımı: Bu retrospektif kohort çalışmasına üçüncü trimesterde tekil gebeliği olan ve tahmini fetal ağırlığı 10. persentilin altında olan 268 kadın dahil edilmiştir. Veriler elektronik tıbbi kayıtlardan elde edilmiş ve ultrason ölçümleri yoluyla fetal ağırlığı tahmin etmek için Hadlock formülü kullanılmıştır. Plasental yetmezlik, preeklampsi, çoğul gebelik veya fetal anomaliler nedeniyle fetal büyüme kısıtlılığı olan hastalar çalışma dışı bırakılmıştır. Çalışma grupları tahmini ve gerçek doğum ağırlıkları arasındaki farklara göre kategorize edildi. Sonuçlar: Analiz, vakaların 24,3ünde tahmini ve gerçek doğum ağırlıkları arasında 10 fark olduğunu gösterdi. Doğum şekli kilo farkı ile anlamlı şekilde ilişkiliydi ve 10 fark olan grupta sezaryen oranı daha düşüktü. Çalışma grupları arasında klinik ve sonografik özellikler açısından anlamlı bir fark bulunmamıştır. Perinatal sonuçlar doğumdaki gebelik yaşı, doğum şekli, cinsiyet veya mekonyum lekeli amniyotik sıvı açısından anlamlı farklılıklar göstermemiştir. Bununla birlikte, doğum ağırlığında anlamlı bir fark vardı ve 10 fark olan grupta daha yüksek doğum ağırlıkları gözlendi. Lojistik regresyon analizi, maternal VKİ, oligohidramniyos, plasental yerleşim, fetal hareket, doğum şekli, uterus çentiği ve ağırlık farklılıkları arasında anlamlı bir ilişki olmadığını ortaya koymuştur. Sonuçlar: Bu çalışma SGA fetüslerde fetal ağırlığın doğru bir şekilde tahmin edilmesinin zorluklarını vurgulamaktadır. Doğum öncesi yönetimi iyileştirmek ve olumsuz sonuç riskini azaltmak amacıyla, bu vakalarda ek faktörleri tanımlamak ve fetal ağırlığı tahmin etmek için daha güvenilir yöntemler geliştirmek için daha fazla araştırmaya ihtiyaç vardır.
