Abstract

Objective: To make predictions for antenatal evaluation by using anthropometric data of the newborns which undergo the complications of brachial plexus palsy, clavicle fracture and shoulder/humerus fracture in cases with low risk in terms of shoulder dystocia. Methods: After the risk factors that may cause deliveries with dystocia such as fetal macrosomia, maternal diabetes, maternal obesity and excessive weight gain during pregnancy, history of shoulder dystocia, labor induction and epidural anesthesia were ruled out, birth complication cases found in the hospital database retrospectively were matched one by one with data of the newborns which had same obstetric and demographic characteristics, same weights and genders but did not undergo labor trauma. Results: A total of 185 newborn complications were observed, and of these complications, 149 were classified as clavicle fracture, 8 as shoulder and humerus fracture, and 28 as brachial plexus palsy. It was seen that the 2nd stage of labor was significantly longer in the cases which underwent birth complication (p=0.01; 22.41±6.98 minutes vs. 24.23±6.43 minutes). Shoulder dystocia was more frequent in the study group which had complications (p=0.0001; 32.97% vs. 2.7%). In terms of anthropometric measurements, the ROC analysis of thorax circumference / head circumference ratio was significant, and it was seen that shoulder dystocia and the complications could be predicted in case that the ratio is higher than 0.97 (AUC=0.903; sensitivity 77.84%, specificity 89.73%, PPV 88.3%, NPV 80.2%, LR 7.58). It was found that the rate of complications increased significantly in cases which were above 4000 g (p=0.029). Conclusion: Shoulders and its extensions are vulnerable to trauma within birth canal. In our hypothesis, neonatal anthropometric data were significantly correlated with the complications. In order to make a prediction, bisacromial diameter and thorax circumference measurements as well as fetal head measurements may be helpful during antenatal period and labor in particular.

Özet

Amaç: Omuz distosisi açısından düşük risk taşıyan olgularda brakiyal pleksus felci, klavikula kırığı ve omuz/humerus kırığı komplikasyonları nı yaşayan yenidoğanların antropometrik verilerinden yararlanarak antenatal değerlendirmeye yönelik öngörü oluşturmak. Yöntem: Distosik doğuma neden olabilecek fetal makrozomi, maternal diyabet, maternal obezite ve gebelikte aşırı kilo alımı, omuz distosisi öyküsü, doğum indüksiyonu, epidural anestezi gibi risk faktörleri dışlandıktan sonra hastane veri tabanından retrospektif olarak çıkarılan doğum komplikasyonu olguları, aynı obstetrik ve demografik özellikleri taşıyan, ancak doğum travması yaşamayan, aynı tartı ve cinsiyette yenidoğan verileri ile birebir eşleştirildi. Bulgular: 185 yenidoğan komplikasyonu gözlendi; bunların 149 tanesi klavikula kırığı, 8 tanesi omuz ve humerus kırığı, 28 tanesi de brakiyal pleksus felci olarak sınıflandırıldı. Doğum komplikasyonu yaşanan olgularda doğumun 2. evresinin anlamlı şekilde daha uzun olduğu görüldü (p=0.01; 22.41±6.98 dakikaya karşılık 24.23±6.43 dakika). Omuz distosisi, komplikasyonların yaşandığı çalışma grubunda daha sık gözlendi (p=0.0001; sıklığı %32.97’ye karşılık %2.7). Antropometrik ölçümler açısından göğüs çevresi / baş çevresi oranları nın ROC çalışması anlamlı saptandı, oranın 0.97’den büyük olması durumunda (AUC=0.903; sensitivite %77.84, spesifisite %89.73, PPD %88.3, NPD %80.2, LR 7.58) omuz distosisi ve komplikasyonları öngörebileceği görüldü. Komplikasyonların 4000 gramın üstündeki olgularda anlamlı olarak artmaya başladığı saptandı (p=0.029). Sonuç: Doğum kanalı içinde omuzlar ve uzantıları travmaya açıktı r. İleri sürdüğümüz hipotezde neonatal antropometrik veriler komplikasyonlar ile anlamlı şekilde korele bulunmuştur. Bir öngörüde bulunmak için, antenatal dönem ve özellikle de eylem sırasında fetal baş ölçümlerinin yanı sıra ayrıca bisakromiyal çap ve göğüs çevresi ölçümleri yardımcı olabilir.
