Özet
İntrauterin gelişme geriliği (IUGG) olan vakalarda umblikal arter Doppler analizinin prediktif değerini saptamak. Çalışmamıza IUGG saptanan 21 gebe alındı ve umblikal arter Doppler analizi yapıldı. Doğumdan hemen sonra umblikal arter kan örneği alınarak kan gazı değerleri tespit edildi. Yenidoğanların apgar skorları, yenidoğan ünitelerinde kalış süreleri ve perinatal mortaliteleri kaydedildi. S/D oranları ve diğer Doppler indeksleri (RI ve PI) ile doğum ağırlıkları, umblikal arter kan pH'sı, kan PO2 seviyeleri ve PCO2 seviyeleri arasında korelasyon tespit edilemedi. Umblikal arter kan pH'sı ile PO2 değerleri arasında korelasyon saptandı(p<.005, r=.526). Umblikal arter kan pH'sı, PO2 ve PCO2 değerleri ile yenidoğan apgar skorları veya doğum ağırlıkları arasında korelasyon izlenmedi. Umblikal arter Doppler çalışmalarının perinatal morbidite üzerindeki prediktif değerinin tam olarak saptanabilmesi için, daha fazla vaka sayılı ve sonuçların diğer antenatal testlerle karşılaştırıldığı çalışmalara ihtiyaç vardır
Abstract
OBJECTIVE: To evaluate the predictive value of umblical artery Doppler velocimetry for intrauterine fetal circulation to detect the SGA fetuses in need of antepartum surveillance. We present the preliminary results of our institute. STUDY DESİGN: The study population consisted of 21 pregnant women diagnosed as IUGR. Umblical artery doppler analysis were performed for each patient. Just after delivery, umblical artery blood samples were taken and analysis of umblical artery blood gases were performed immediately. Apgar scores of newborns, admissions of neonatal intensive care units and perinatal mortality were recorded. RESULTS: Although the mean S/D (±SD) ratio was higher in fetuses with lower birth weight percentile this difference was not statistically significant. There was no significant correlation either between umblical artery blood pH levels and S/D ratios or between umblical artery blood PO2 levels and S/D ratios. A slight positive correlation between umblical artery S/D ratios and blood PCO2 levels was also not statistically significant. No significant correlation was demonstrated between other doppler indices ( RI and PI ) and blood pH and gases (PCO2 and PO2), as well. There was a statistically significant positive correlation between umblical artery blood pH and PO2 values (p< 0.005, r = 0.526). There was no correlation between umblical artery blood pH , PO2 ,PCO2 values and apgar scores or birth weights of the newborns . CONCLUSION: In conclusion, data from a few studies, in which DVW analysis of umblical artery is measured, give evidence of an association between elvated S/D ratios and perinatal morbidity. Prospective randomized trials in large populations are needed to test the predictive value of uterine artery FVW as a test for fetal surveillance versus other antenatal tests (nonstress test, biophysical profile scoring).
