Brainstem evoked response audiometry and risk factors in premature infants

Amaç: Bu çalışmada preterm bebeklerde “Joint Committee on Infant Hearing”e göre olası risk faktörlerinin ve preterm anemisinin işitsel beyin sapı cevabı (BAER) üzerine etkisi incelenmiştir. Yöntem: Bu amaçla, 29 term bebekten doğumdan sonraki 48.saat ve 7.günler arası BAER kaydı alındı. Yirmidokuz preterm bebeğe ise BAER, postkonsepsiyonel yaşları (gebelik haftası+doğum sonrası yaşı) 39.4±0.8 hafta (38-42) olunca uygulandı. Doğum şekli, 1500 g’ın altında doğum ağırlığı, fototerapi sınırlarını aşan hiperbilirubinemi, aminoglikozid tedavisi, respiratuar distres sendromu, düşük Apgar skoru ve prematüre anemisi risk faktörü olarak değerlendirmeye alındı. I,III,V latens ve I-III, III-V, I-V interpik latensleri analiz edildi. Bulgular: Term ve preterm bebeklerde aynı postkonsepsiyonel yaşta BAER parametreleri karşılaştırıldığında (latens ve interpik latensları) istatistiksel bir fark saptanmadı. Doğum şekli,

Preterm bebeklerde risk faktörleri ve işitsel beyin sapı cevabı

Objective: In this study; we evaluated the effects of possible risk factors according to the Joint Committee on Infant Hearing in preterm infants and physiologic anemia of prematurity on brainstem auditory evoked response (BAER) measurement variables. Methods: For this aim, twenty-nine term newborn infants underwent the BAER recording session between 48 hours to 7 days of age. In 29 preterm infants, BAER was performed at a mean postconceptional (gestational age + age after birth) age of 39.4 ± 0.8 weeks (38-42 weeks). Type of delivery, birth weight <1500 g, hyperbilirubinemia exceeding phototherapy limits, aminoglycoside therapy, respiratory distress syndrome, low Apgar scores, and physiologic anemia of prematurity were evaluated. I,III,V peak latencies and I-III, III-V, I-V interpeak latencies were measured and analyzed. Results: There were no significant differences for latencies and interpeak latencies between term and preterm groups at the same postconceptional age. We found that type of delivery (caesarean section), birth weight <1500 g, hyperbilirubinemia exceeding phototherapy limits, and low Apgar scores affected some of the BAER parameters (p<0.05). However we did not find any effect of aminoglycoside (amicasin and/or netilmicin) therapy, respiratory distress syndrome on BAER measurement variables. Although the mean latencies and interpeak latencies in anemic preterm group were higher than non-anemic preterm group, statistically significant difference was not found (p>0.05). Conclusion: We suggest that the effect of anemia of prematurity on BAER parameters should be studied in a larger group of infants
