Amaç
Ciddi ve orta derece preterm bebeklerde kordon kanı nötrofil değerlerinin erken yenidoğan sepsisi (EYS) ve EYS risk etmenleri ile ilişkisinin belirlenmesi amaçlandı.
Çalışma planı
Geriye dönük çalışmamızda ünitemizde en az yedi gün yatırılan, 28-34 gebelik haftaları arasında doğan olgular değerlendirildi. Göbek kordonundan ya da yaşamın ilk iki saatinde venöz alınan kan sayımları ile kan kültürü sonuçları, CRP değerleri, EYS için risk etmenleri ve klinik özellikler kaydedildi.
Bulgular
Hastaların (n=100) ortalama doğum ağırlıkları ve gebelik haftaları sırasıyla 1617±408 gram ve 32,19±1,6 hafta idi. Olguların 33’ünün kordon, 67’sinin doğum sonrası ilk iki saat içinde alınan venöz nötrofil sayıları değerlendirildi. Kordon kanı ve venöz nötrofil değerleri arasında fark saptanmadı (p=0,936). Erken yenidoğan sepsisi ve EYS risk etmeni olanlarla olmayanlar arasında nötrofil değerleri açısından fark saptanmadı (sırasıyla p=0,076, 0,95). Nötrofil düzeyleri gebelik haftası ve doğum ağırlığı ile aynı, CRP değerleri ile zıt yönlü ilişikili saptandı (sırasıyla r, p= 0,282, 0,004; 0,437, 0,0001; -0,209, 0,037).
Sonuç
Kordon kanı ve venöz kan nötrofil düzeyleri ile EYS ve EYS risk etmenleri arasında ilişki saptanmadı. Bulgularımız preterm bebeklerde nötrofil değerlerinin gebelik haftası ve doğum ağırlığı göz önüne alınarak değerlendirilmesi gerektiğini düşündürmektedir.

Introduction
It was aimed to determine the relationship between cord blood neutrophil values and early onset neonatal sepsis (ENS) and ENS risk factors in very and moderate preterm infants.
Methods
In our retrospective study, the cases who were born between 28-34 weeks of gestation and hospitalized for at least seven days were evaluated. Blood counts obtained from umbilical cord or in the first two hours of life, blood culture results, CRP values, risk factors for ENS, and clinical features were recorded.
Results
The mean birth weight and gestational age of patients (n=100) were 1617±408 grams, and 32.19±1.6 weeks, respectively. In the 33 of the cases the cord blood, and in the 67 of the cases venous neutrophil counts taken within the first two hours after delivery were evaluated. There was no difference between cord and venous blood neutrophil values (p= 0.936). There was no difference in terms of neutrophil values between those with/without ENS and with/without ENS risk factors (p = 0.076, 0.95, respectively). Neutrophil levels were positively correlated with gestational week and birth weight, and negatively correlated with CRP values (r, p = 0.282, 0.004; 0.437, 0.0001; -0.209, 0.037, respectively).
Conclusion
No relationship was found between cord blood/ venous blood neutrophil levels and ENS/ ENS risk factors. Our findings suggest that neutrophil values should be evaluated by considering gestational age and birth weight in preterm infants.
