Abstract

Objective: The aim of the study is determination of myocardial performance index (MPI/Tei index) using pulsed (PD) and tissue Doppler (TD) techniques to show cardiac response in newborns with hypoxic-ischemic encephalopathy (HIE) and healthy newborns and eventually evaluation of the differences between these two techniques. Methods: The study is a prospective observational study. Twenty term newborns diagnosed as perinatal asphyxia during postnatal 24 hours due to the defined criteria and fifty healthy term neonates as control group were included the study. Hypoxic group was divided into two groups with Sarnat stages, Sarnat Stage 1 and 2-3. MPIs (Tei indexes) were calculated with PD and TD echocardiographic techniques in all groups after the 24 hours of birth and one year later. The statistical differences between same techniques were calculated with Kruskal-Wallis test and Z score was used to compare the superiority of two techniques. Results: The MPI values calculated by PD (0.41±0.04, 0.51±0.02) and TD (0.59±0.04, 0.51±0.02) during the first day of life in Sarnat Stage 2-3 in both ventricles were significantly higher than the control group (p

Özet

Amaç: Çalışmanın amacı; hipoksik iskemik ensefalopatili (HİE) ve sağlıklı term yenidoğan bebeklerde, kardiyak etkilenmeyi göstermek amacı ile pulsed (PD) ve doku Doppler (DD) tekniklerini kullanarak miyokart performans indeksini (MPİ/Tei indeksi) belirlemek ve bu iki teknik sonuçları arasında ortaya çıkan farklılıkları değerlendirmektir. Yöntemler: Çalışma prospektif gözlemsel bir çalışmadır. Postnatal ilk 24 saat içinde belirlenen kriterlere göre perinatal asfiksi tanısı konulan 20 term yenidoğan ve kontrol grubu olarak sağlıklı, 50 term yenidoğan bebek çalışmaya alındı. HİE grup Sarnat evrelemesine göre Sarnat Evre 1 ve 2-3 olmak üzere iki gruba ayrıldı. Kontrol ve hasta gruplarına doğumdan sonraki ilk 24 saat içerisinde ve bir yıl sonra, PD ve DD ekokardiyografi teknikleri uygulanarak MPI hesaplandı. Aynı ölçüm teknikler ile elde edilen veriler Kruskal-Wallis testi ile iki tekniğin birbirine üstünlüğü ise Z skoru olarak hesaplandı. Bulgular: Sarnat evre 2-3 grubunda, hayatın ilk gününde her iki ventrikülde PD (0.41±0.04, 0.51±0.02) ve DD (0.59±0.04, 0.51±0.02) ile bakılan bakılan MPİ kontrol grubuna göre anlamlı derecede yüksek bulundu (p
