Ultrasonografi ile Ölçülen Tahmini Fetal Ağırlığa Etki Eden Faktörler

Year 2016, Volume: 43 Issue: 2, 294 - 298, 01.06.2016

Abstract

Amaç: Bu çalışmada ultrasonografi ile yapılan tahmini fetal
ağırlık (TFA) ölçümlerinin doğruluğuna etki edebilecek
faktörler araştırılmıştır.
Yöntemler: Haziran 2011 ve Ocak 2012 tarihleri arasında
3. basamak bir hastanenin doğum salonunda doğum
yapan 165 gebe çalışmaya dahil edildi. Çalışmaya katılacak
gebelerin seçim kriterleri; herhangi bir ek hastalığı
olmaması, gebeliğin 37- 42 haftalar arasında olması, ultrasonografi
ölçümünden 48 saat sonra doğurmaları idi.
Ultrasonografi ölçümleri aynı hekim tarafından yapıldı.
Gebelerin yaşları, boyları, kiloları, obstetrik özgeçmişler
ve gebelik izlem bulguları kayıt edildi.
Bulgular: Annenin daha önce doğum yapmış olup olmamasının,
paritenin, bebeğin cinsiyetinin, amnionda
mekonyum bulunmasının, fetal prezantasyonun TFA’nın
isabetli hesaplanması üzerine istatistiksel olarak anlamlı
etkisi olmadığı görüldü. TFA’nın, bebek doğum ağırlığı ile
olan farkının parite açısından karşılaştırıldığında; nulliparlarda
ortalama fark 104,48 ± 84 gr, multiparlarda ortalama
fark 94,2±81 gr idi (p=0,44). TFA’nın, bebek doğum
ağırlığı ile olan farkı erkek bebeklerde ortalama 98,22±79
gr, kız bebeklerde ortalama fark 98,15±86 gr idi (p=0,99).
TFA- bebek doğum ağırlığı farkının bebeğin prezentasyon
şekli açısından; baş prezentasyon görülen bebeklerde ortalama
fark 96,92±81 gr, makat prezentasyon bebeklerde
fark 110,9±90 gram idi (p=0,53). TFA’nın, bebek doğum
ağırlığı ile olan farkı mekonyumlu mayi olan bebeklerde
95,36±79 gr, mekonyumlu olmayan bebeklerde 98,82±83
gr idi (p=0,83).
Sonuç: Çalışmamızda, bebek cinsiyeti, prezentasyonu,
amnion sıvıda mekonyum varlığı, annenin paritesi ile ultrasonografiyle
ölçülen TFA ve bebek doğum ağırlığı arasındaki
farklar bakımından anlamlı farklılık izlenmemiştir

Factors Affecting Estimated Fetal Weight Measured by Ultrasound

Year 2016, Volume: 43 Issue: 2, 294 - 298, 01.06.2016

Abstract

Objective: In this study, we aimed to evaluate the fac­tors that affect the accuracy of estimated fetal weight in ultrasound. Methods: This study was conducted in 3rd degree hospi­tal antenatal outpatient clinic and perinatology inpatient clinic between June 2011 and January 2012. The data were obtained from 165 pregnant women. Inclusion cri­teria were; no additional diseases, giving birth within 48 hours after ultrasound. The same physician executed all ultrasound process. Age, height, weight, obstetric history and obstetric follow –up findings were recorded. Results: Fetal gender, fetal presentation, presence of meconium in amniotic fluid, maternal parity, did not sig­nificantly affect the accuracy of fetal weight estimation by ultrasound. The mean difference between estimated fetal weight and birth weight was 104.48±84 gr in nullipars and 94.2±81 gr in multipars (p=0.44); mean difference was 98.22±79 gr in male babies and 98.15±86 gr in female babies (p=0.99). Mean difference between estimated fetal weight and birth weight was 96.92±81 gr in babies with cephalic presentation and 110.9±90 gr in babies with breech presentation (p=0.53); this difference was 95.36±79 gr in babies with amniotic fluid with meconium and 98.82± 83 gr in babies with amniotic fluid without me­conium (p=0.83). Conclusion: Fetal weight is estimation is one of key points in the obstetrician’s intrapartum managament. And it is important to make fetal weight estimation accurately. In our study, consistent with literature, we observed that fetal gender; meconium presence in amniotic fluid, fetal presentation, maternal parity does not significantly effect the accuracy of fetal weight estimation by ultrasound.
