Abstract
Amaç: Neonatal hipoglisemi (NH) yenidoğan pratiğinde sık karşılaşılan bir durumdur. Bu çalışma ile doğumdan sonra NH gelişen yenidoğanlarda yaşamın ilk saatlerindeki serebral doku oksijenasyonu ve serebral kan akımının değerlendirilmesi amaçlanmıştır.
Yöntem: Prospektif yürütülen çalışmaya doğumdan sonra NH gelişen (n=50) ve gelişmeyen (n=50) yenidoğan bebekler dahil edildi. Her iki gruptaki bebeklerde yaşamın ilk 24 saati boyunca near-infrared spectroscopy (NIRS) ile devamlı bölgesel serebral doku oksijenasyonu (rcSO2 ) ölçüldü. Yaşamın ilk saati ve 24.saatinde bebeklerin orta serebral arter (MCA) kan akımları Doppler ultrasonografi ile değerlendirildi. NH gelişen ve gelişmeyen gruplar karşılaştırıldı.
Bulgular: Bebeklerin ortalama gebelik haftası, doğum ağırlıkları ve hemoglobin düzeyleri benzerdi. NH gelişen ve gelişmeyen bebekler karşılaştırıldığında NH gelişen bebeklerde ortalama rcSO2 değerleri anlamlı yüksek ve fraksiyone doku oksijen ekstraksiyon (FTOE) değerleri anlamlı düşük bulundu. Yaşamın ilk saatinde ve 24. saatinde ölçülen, vasküler direnci gösteren serebral doppler indeksleri (Pulsatilite indeksi:PI) de NH gelişen grupta anlamlı olarak yüksekti.
Sonuç: Bu çalışma ile NH gelişen yenidoğanlarda serebral dolaşımın ve oksijenasyonun bozulduğu gösterilmiştir. Hipoglisemi gelişen grupta yüksek ölçülen PI, serebral vasküler direncin arttığını göstermektedir. Bu grupta yüksek ölçülen rcSO2 değerlerinin azalmış serebral akımı kompanse etmek için gelişen serebral otoregülasyon sonucu geliştiği düşünülmektedir. FTOE düzeylerinin düşük olması ise serebral otoregülasyon mekanizmalarına rağmen NH’de serebral dolaşımın ve serebral oksijenasyonun bozulduğunu düşündürmüştür. Bu nedenle asemptomatik olsalar dahi NH gelişen bebeklerin uzun dönem nörolojik gelişimlerinin takip edilmesi gerekmektedir.

Abstract
Purpose: Neonatal hypoglycemia (NH) is frequent in neonatology practice. This study aimed to evaluate the regional cerebral tissue oxygenation and cerebral blood flow in neonates who developed NH immediately after birth.
Methods: This prospective study included infants who developed NH (n=50) and the control healthy term neonates (n=50). Infants with NH are monitored in terms of continuous regional cerebral tissue oxygenation (rcSO2 ) via near-infrared spectroscopy (NIRS) during the first 24 hours of life. Middle cerebral artery (MCA) blood flow was evaluated by doppler ultrasound at the first and 24 hours of life. The pulsatility index (PI) was measured to assess cerebral vascular resistance.
Results: The mean gestational age, birth weights and hemoglobin levels of infants were similar. The mean rcSO2 was continuously higher and fractional tissue oxygen extraction (FTOE) was lower in infants with NH. The mean MCA PI values at the first and 24th hours of life were significantly higher in NH.
Conclusions: This study shows that cerebral perfusion was impaired in infants with NH. They had higher rcSO2 , lower FTOE values and increased PI compared to healthy term infants. We suggest that increased PI may reflect increased vascular resistance and higher rcSO2 values associated with increased cerebral perfusion as a compensatory auto-regulatory response mechanism. Significantly lower FTOE values may dedicate decreased cerebral tissue oxygen extraction resulting from impaired cerebral perfusion even in the presence of auto-regulatory mechanisms. Therefore, even if they are asymptomatic, long term neurological outcomes should be followed in infants with NH due to impaired cerebral perfusion.
