YENÝDOÐANDA POLÝSÝTEMÝ

Polisitemi yenidoðan döneminde sýk karþýlaþýlan bir sorun olup taný ve tedavisi zamanýnda yapýlmadýðý takdirde önemli komplikasyonlara yol açabilir. Biz bu prospektif çalýþmamýzda, yenidoðan servisimizdeki polisitemi insidansýný, risk faktörlerini ve oluþan komplikasyonlarý inceledik. Çalýþmamýzýn materyelini 910 yenidoðan oluþturdu. Bu vakalarýn ayrýntýlý prenatal ve natal öyküleri alýnýp fizik incelemeleri yapýldý. Onikinci saatte kapiller hematokritlerine bakýldý. %70'in üstünde bulunanlarýn venöz hematokritleri ölçüldü. Venöz hematokritleri % 65 ve üzerinde olan 50 yenidoðan polisitemik olarak kabul edildi ve tedaviye alýndý. Venöz hematokritleri düþük olanlar kontrol grubunu oluþturdu. Yenidoðanlarýmýz arasýnda polisitemi insidansý % 5.49 olarak hesaplandý. Vakalarýn % 36'sý semptomatikti. Risk faktörleri irdelendiðinde polisitemik bebeklerde düþük doðum aðýrlýðý, fetal distress, asfiksi ve preeklamptik anne, kontrol grubuna göre daha yüksek oranda idi. Komplikasyon olarak polisitemik grupta % 4 akut renal yetmezlik, % 2 konjestif kalp yetmezliði ve % 2 oranýnda konvülsiyon gözlendi. Sonuç olarak, yenidoðan döneminde önemli bir sorun olan polisitemi açýsýndan risk grubunun izlenmesi gerektiði bir kez daha vurgulandý.

POLYCYTHEMIA OF THE NEWBORN

Polycythemia which if untreated may cause important complications, is a common problem during neonatal period. In our prospective study, we evaluated the incidence of polycythemia, the risk factors and it's complications. 910 newborns were included in the study. Prenatal and natal history, physical examination was thoroughly recorded. Capillary hematocrit was sampled at 12 hours after birth. Venous hematocrit was obtained from the ones with heinatocrits more than 70%. 50 newborns with venous hematocrits more than 65% were accepted as polycythemic and treated. The patients with low venous hematocrits composed the control group. Polycythemia incidence was found to be 5.49% among our newborns. 36% of them were asymptomatic. Risk factors such as low birth weight, fetal distress, asphyxia and preeclampsia in mother were more frequent among polycythemic group. 4% acute renal failure, 2% congestive heart failure and 2% convulsion was observed as complications. As a result, the importance of close follow up of risk groups for polycythemia which is a serious problem in neonatal period should be emphasized.
