    A Novel Atraumatic Tourniquet Technique for Excessive Bleeding during Cesarean Sections
    (Hindawi Ltd, 2017) Buke, Baris; Canverenler, Emre; Akkaya, Hatice; Akercan, Fuat
    Objective. Controlling excessive bleeding in cesarean sections which may cause a life-threatening event even under well-prepared conditions. We used a novel atraumatic tourniquet technique to temporary arrest blood flow through the uterine and ovarian vessels and compare with other techniques. Toothless vascular clamps were used as clamp. Methods. Tourniquet technique performed postpartum hemorrhage (PPH) cases (19 out of 37) were compared with 18 other cases with PPH. Results. The difference between preoperative and postoperative hemoglobin values was significantly lower in the study group as well as the number of blood products needed during and after surgery. Conclusions. This technique not only prevented massive bleeding from the uterus but also allowed physicians time to consider the necessity of further interventions.

    Prediction of neonatal respiratory distress syndrome via pulmonary artery Doppler examination
    (Taylor & Francis Ltd, 2019) Buke, Baris; Destegul, Emre; Akkaya, Hatice; Simsek, Deniz; Kazandi, Mert
    Objective: We aimed with this study to evaluate the role of pulmonary artery acceleration time to ejection time ratio (PATET) in the prediction of respiratory distress syndrome (RDS) in preterm neonates. Materials and methods: In this prospective cohort study, 105 singleton pregnant women with no congenital abnormalities and pregnancy complications who delivered before 37 weeks of gestational age were included. All the patients underwent ultrasound examination to obtain fetal pulmonary artery Doppler. 15 patients were excluded from the study as they did not give birth within 3 days subsequent to ultrasound examination, or inadequate Doppler measurements. After delivery the neonates were grouped according to diagnosis of RDS as RDS + and RDS-. Results: One hundred five women met the inclusion criteria. Regarding the Doppler findings; only the PATET ratio was significantly different between the groups (0.2965 +/- 0.042 versus 0.386 +/- 0.068 p < .001, Z = -5.206). There was an inverse correlation between the diagnosis of RDS in the neonates and the PATET values, even after adjusted for gestational age estimated fetal weight and fetal gender (r = -0.52 and p = .0017). A cut-off value of 0.327 provided optimal specificity of 77.1%, a sensitivity of 90.9%, a negative predictive value of 95.4%, and a positive predictive value 52.7%. Conclusions: In consideration of these results fetal PATET ratio is a promising noninvasive tool to predict RDS in cases of preterm deliveries.

    Relationship between first trimester aneuploidy screening test serum analytes and placenta accreta
    (Taylor & Francis Ltd, 2018) Buke, Baris; Akkaya, Hatice; Demir, Sibel; Sagol, Sermet; Simsek, Deniz; Basol, Gunes; Barutcuoglu, Burcu
    Objective: The aim of this study is to determine whether there is a relationship between first trimester serum pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotropin (fhCG) MoM values and placenta accreta in women who had placenta previa.Study design: A total of 88 patients with placenta previa who had first trimester aneuploidy screening test results were enrolled in the study. Nineteen of these patients were also diagnosed with placenta accreta. As probable markers of excessive placental invasion, serum PAPP-A and fhCG MoM values were compared in two groups with and without placenta accreta.Results: Patients with placenta accreta had higher statistically significant serum PAPP-A (1.20 versus 0.865, respectively, p=0.045) and fhCG MoM (1.42 versus 0.93, respectively, p=0.042) values than patients without accreta.Conclusions: Higher first trimester serum PAPP-A and fhCG MoM values seem to be associated with placenta accreta in women with placenta previa. Further studies are needed to use these promising additional tools for early detection of placenta accreta.
