Amaç
Bu araştırmada prematüre retinopatisi ‘’retinopathy of prematurity’’ (ROP) muayenesi sırasında kullanılan tıbbi aletlerle ilişkili gelişen Adenovirus konjonktiviti (AK) salgın analizinin sunulması amaçlanmıştır.
Gereç ve Yöntemler
Bu çalışmada; retrospektif olaraK Sakarya Eğitim ve Araştırma Hastanesinde meydana gelen yenidoğan AK salgını incelendi. Hasta verileri dosyalardan ve enfeksiyon sürveyans kayıtlarından elde edildi. Hastalara ait göz sürüntü örneklerinden ve ROP muayenesi sırasında kullanılan on adet tıbbi aletten (blefarosta, indirekt oftalmoskop, skleral depresör ve 20-28 diyoptrilik mercekler) bakteriyolojik kültür ve Adenovirus için polimeraz zincir reaksiyon (PZR) incelemeleri yapıldı.
Bulgular
Yenidoğan yoğun bakım ünitesinde (YYBÜ) çalışan bir hemşirenin gözünde AK tespit edildikten sonra yatan bir bebekte ve daha sonrasında üç bebekte daha AK gelişti. AK gelişen dört bebeğin hepsi de aynı gün ROP muayenesi olmuştu. Göz muayenelerinin steril ya da tek kullanımlık aletlerle yapılamadığı, bir bebeğin muayenesinden diğerine geçerken %10 povidon iyotla dezenfeksiyon yapıldığı ve sonrasında ROP muayenesinde tekrar kullanıldığı anlaşıldı. Göz sürüntü örneklerinin bakteriyolojik kültüründe patojen bakteri üremedi. Dört yenidoğan ve hemşirenin göz sürüntü örneklerinde ve ROP muayenesinde kullanılan dört tane blefarosta adlı cihazda PZR ile Adenovirüs DNA'sı saptandı.
Sonuç
YYBÜ de yatan bebeklerde standart önlemlere uyulmadığında AK salgınları gelişebilir. Dezenfeksiyon süreçleri standardize uygulamalarla yapılmalı, standartlardan ödün verilmemeli ve bu uygulamalar sürekli olarak kontrol edilmelidir.

Analysis of Adenovirus Conjunctivitis Outbreak in a Neonatal Intensive Care Unit

Öz

Objective In this study, it is aimed to present the outbreak analysis of Adenovirus conjunctivitis (AC) that develops associated with medical devices used during retinopathy of prematurity (ROP) examination for retinopathy of prematurity.
Materials and Methods In this study; The neonatal AK outbreak that occurred at the Sakarya Training and Research Hospital was retrospectively analyzed. Patient data were obtained from files and infection surveillance records. Bacteriological culture and polymerase chain reaction (PCR) examinations for Adenovirus were performed from the eye swab samples of the patients and ten medical instruments (blepharosta, indirect ophthalmoscope, scleral depressor and 20-28 diopters) used during ROP examination.
Results
After AK was detected in the eyes of a nurse working in a neonatal intensive care unit (NICU), one inpatient baby and three more babies developed AK. All four babies who developed AK had ROP examination on the same day. It was understood that eye examinations could not be performed with sterile or disposable instruments, disinfection was performed with 10% povidone iodine while passing from one baby's examination to another, and then it was used again in ROP examination. No pathogenic bacteria were grown in the bacteriological culture of eye swab samples. Adenovirus DNA was detected by PCR in eye swab samples of four newborns and nurses and in four devices called blepharosta used for ROP examination.
Conclusion
AC outbreaks develop in infants hospitalized in the NICU when standard precautions are not followed. Disinfection processes should always be carried out with standardized practices, standards should not be compromised and these practices should be constantly monitored.
