Amaç: Çalışmanın amacı; beyin ölümü tanısı almış hastaların optik sinir kılıf çapı (OSKÇ) ile beyin ölümü etiyolojisi arasındaki ilişkiyi ortaya koymak ve OSKÇ ile apne testi öncesi ve sonrası kan gazı parametreleri arasında korelasyon olup olmadığını araştırmaktır.

Araçlar ve Yöntem: Beyin ölümü tanısı almış 92 hastanın sağ ve sol göz için OSKÇ değerleri, parsiyel karbondioksit basıncı (pCO2), apne testi öncesi ve sonrası kan gazı parametreleri retrospektif olarak incelendi.

Bulgular: Subaraknoid kanama ve intraserebral kanama en sık görülen beyin ölümü nedenleriydi. Sağ göz için ortalama OSKÇ değeri 6.37±1.03 mm, sol göz için 6.43±1.02 mm olarak bulundu. Sadece 8 hastanın OSKÇ çapı 5.00 mm’nin altında ölçüldü. pCO2’nin yüzdelik değişimi ile OSKÇ arasında istatistiksel olarak anlamlı korelasyon bulunmadı (p>0.05).

Sonuç: Çalışmanın sonucuna göre beyin ölümü tanısı almış hastalarda OSKÇ değerleri pCO2’den bağımsız olarak çok yüksektir. Komadaki hastaların beyin ölümü tanısı açısından değerlendirilmesinde OSKÇ’nin kendisine bir yer bulacağını düşünmekteyiz.

Purpose: Purpose of this study is to reveal the relationship between optic nerve sheath diameter (ONSD) and the etiology of brain death and to investigate whether there is a correlation between ONSD and blood gas parameters before and after the apnea test in patients diagnosed with brain death.

Materıals and Methods: The data of 92 patients with brain death diagnoses were retrospectively analyzed for ONSD measurements for each eye, partial carbon dioxide pressure (pCO2), and blood gas parameters before and after the apnea test.

Results: Subarachnoidal and intracerebral hemorrhages were the two most common brain death etiology. The mean ONSD for the right eye was 6.37±1.03 mm. The mean ONSD for the left eye was 6.43±1.02 mm. Only 8 patients had ONSD below 5.00 mm. There was no statistically significant correlation between the percent change of pCO2 and ONSD change (p>0.05).

Conclusion: The present study shows that ONSD values are very high regardless of the partial pressure of carbon dioxide in patients with brain death diagnoses. We can suggest that ONSD can find a place for evaluating comatose patients for brain death diagnosis.
