Abstract

Amaç: Bu çalışmada spontan vaginal doğum yapmış, düşük riskli term gebelerde doğum öncesi bakılan obstetrik Doppler ölçümleri ile fetal doğum ağırlığı arasındaki ilişkiyi araştırmayı amaçladık.
Gereç ve yöntemler: Çalışma kesitsel bir çalışma olup prospektif dizayn edilmiştir.. Çalışmaya 18-45 yaş arasında, 37-41 gebelik haftasında olan ve başvuru anından itibaren 72 saat içerisinde doğum yapmış tekiz gebeler dahil edilmiştir. Doğum öncesi bakılan umblikal arter (UA), uterin arter (UtA) ve orta serebral arter (MCA) Doppler değerleri ile doğum kilosu ilişkisi araştırılmıştır.
Bulgular: Çalışmaya toplam 134 hasta dâhil edildi. Hastaların ortalama yaşı 26,3 ± 6,1 olup, gebelik haftaları ise 39 (37-41) olarak bulundu. UA PI, RI ve S/D oranları ile doğum kilosu arasında istatistiksel olarak anlamlı olmayan, negatif yönlü orta derecede korelasyon izlenmiştir. Ortalama UtA PI ile fetal kilo arasında zayıf, pozitif yönlü ve istatistiksel olarak anlamlı olan ilişki bulunmuştur (r=0,270; p=0,002). Gebelik haftasına göre düzeltme yapıldığında ortalama UtA RI ile fetal kilo arasında zayıf, negatif yönlü ve istatistiksel olarak anlamlı ilişki bulunmuştur (r=-0,245; p=0,004). Serebroplasental oran (CPR) ile doğum ağırlığı arasında gebelik haftasından bağımsız zayıf pozitif ilişki bulunmuştur (r=0,054; p=0,539)
Sonuç: Çalışmamızda gebelik haftasından bağımsız olarak üçüncü trimester düşük riskli gebeliklerde artmış UtA rezistansı ile düşük doğum ağırlığı ilişkili bulunmuştur. UA, MCA ve CPR ile doğum kilosu arasında gebelik haftası düzeltilse de güçlü bir ilişki gözlenmedi.

The relation with the assesment of fetal Doppler and birth weight in low risk third trimester pregnancies

Abstract

Aim: In this study, we aimed to investigate the relationship between prenatal obstetric Doppler measurements and fetal birth weight in low risk term pregnant women who had spontaneous vaginal delivery.
Material and Methods: This study is a prospective cross-sectional study. Singleton pregnant women between the ages of 18-45 who had 37-41 weeks of gestation and who gave birth within 72 hours from the admission to the hospital were included in the study. The relationship between birth weight and the Doppler values of the umbilical artery (UA), uterine artery (UtA) and middle cerebral artery (MCA) were investigated.
Results: A total of 134 patients were included in the study. The mean age of the patients was 26.3 ± 6.1 years, and the median gestational week was found 39 weeks (37-41). There was a moderate negative correlation between the UA PI, RI and S / D ratios and birth weight, which was not statistically significant. A weak, positive and statistically significant relationship was found between the mean UtA PI and fetal weight (r = 0.270; p = 0.002).After adjusting the gestational week, a weak, negative and statistically significant relationship was found between the mean UtA RI and fetal weight (r = -0.245; p = 0.004). There was a weak positive relation between cerebroplasental ratio (CPR) and birth weight (r=0,054; p=0,539).
Conclusion: In our study, raised uterine artery Doppler resistance in the third trimester is independently associated with significantly lower birthweight in low risk third trimester pregnant women. There was not a significant relationship between UA, MCA and CPR even after adjusting the gestational week.
