Preterm erken membran rüptürü olan izole oligohidramniyoz olgularında fetal ağırlığın tahmininde manuel ve otomatik ölçümlerin karşılaştırılması

Amaç Üçüncü trimesterde tespit edilen izole oligohidramniyoz olgularında alternatif ölçüm yöntemlerinin gerçek (aktüel) doğum ağırlığını tahmin etmedeki etkilerinin değerlendirilmesi amaçlandı. Gereç ve Yöntemler Prospektif kohort çalışmamızda, 336/7 ve 366/7 gebelik haftaları arasında 78 gebe değerlendirildi. Rutin biyometrik ölçümler iki boyutlu (2D) ultrasonografi ile elde edildi. Manuel ölçümlerin yapıldığı bölümlere kaliperler yerleştirildi. Daha sonra aynı görüntü üzerinde ultrasonografi cihazı ile otomatik ölçüm alındı. Fetal ağırlık Hadlock II formülü kullanılarak hesaplandı. Bulgular Ortalama manuel ve otomatik tahmini fetal ağırlıklar (TFA) ve gerçek doğum ağırlıkları (aktüel DA) sırasıyla 2281,1 ± 326, 2371,5 ± 324 ve 2417,2 ± 353 idi. Manuel TFA, istatistiksel olarak anlamlı düzeyde hem gerçek (aktüel) DA'dan hem de otomatik TFA'dan daha düşüktü (sırasıyla p = 0.002, p = 0.001). Korelasyon analizinde, gerçek DA ile hem manuel TFA hem de otomatik TFA arasında anlamlı bir pozitif korelasyon bulundu (p

Comparison of manual versus automated measurement to estimate fetal weight in isolated oligohydramnios with preterm prelabor rupture of membranes

Objective It was aimed to evaluate the effects of alternative measurement methods in estimating actual birth weight (actual BW) in third-trimester isolated oligohydramnios. Methods In our study in prospective design, 78 pregnant women between 336/7and 366/7 weeks of gestation were evaluated. Routine biometric measurements were obtained through two-dimensional (2D) ultrasonography. Calipers were placed in the sections where the measurements were made for manual measurement. Then, automatic measurement was obtained by sonography device on the same image. Fetal weight was estimated using the Hadlock II formula. Results The mean manual and automated estimated fetal weights (EFWs) and actual birth weights (actual BWs) were 2281.1±326, 2371.5±324 and 2417.2±353, respectively. Manual EFW was lower than both actual BW and automated EFW at a statistically significant level (p = 0.002, p = 0.001, respectively). In correlation analysis, a significant positive correlation was found between actual BW and, both manual EFW and automated EFW (p
