Abstract

Objective: The aim of this feasibility study was to investigate the first attempt success of ultrasonography (USG) in paediatric patients in predicting an appropriate cuffed endotracheal tube (ETT) size. Methods: Fifty children who were 1-10 years of age and who received general anaesthesia with endotracheal intubation for adenoidectomy or adenotonsillectomy were enrolled in the study. In all participants, the transverse diameter of the subglottic airway was measured with USG at the cricoid level without ventilation. The outer diameter (OD) of the maximum allowable ETT was chosen according to the measured subglottic airway diameter. In the presence of resistance to passage of the tube into the trachea or in the absence of an audible leak at airway pressure of >25 cm H2 O, the ETT was replaced with a tube whose internal diameter (ID) was 0.5 mm smaller. If a leak was audible at airway pressures of 25 cm H2 O or if a peak airway pressure of >25 cm H2 O was observed during ventilation, the tube was changed to a tube one size larger. The OD of the best-fit ETT was converted to the ID. The best-fit ID, the requirement for ETT replacement, the duration of airway diameter measurement by USG and the peak airway pressure were recorded. Results: The success rate of the first attempt with USG was 86%; the ETT was replaced in five patients with a tube one size larger and in two patients with a tube one size smaller. Conclusion: Our findings show the subglottic diameter measured by USG to be a reliable predictor in estimating the appropriate paediatric ETT size.

Özet

Amaç: Bu fizibiliti çalışmasının amacı pediyatrik hastalarda uygun büyüklükte kaflı endotrakeal tüpün (ETT) öngörülmesinde ultrasonografinin (USG) ilk girişim başarısını araştırmaktır. Yöntemler: Çalışmaya 1-10 yaş arası adenoidektomi veya adenotonsillektomi için endotrakeal entübasyon ile genel anestezi alan 50 çocuk dahil edilmiştir. Bütün katılımcılarda subglottik havayolunun transvers çapı krikoid kartilaj seviyesinden ventilasyon yapılmadan ultrasonografi ile ölçülmüştür. izin verilen maksimum ETT dış çapı (DÇ) ölçülen sublottik havayolu çapına göre seçilmiştir. Tüpün trakeadan geçişi sırasında dirençle karşılaşılması halinde veya havayolu basıncı >25 cm H2 O'da duyulabilen kaçak varlığında ETT iç çapı (iÇ) 0,5 mm olan bir başkasıyla değiştirilmiştir. Eğer havayolu basıncı 25 cm H2 O'ya ulaşmıyorsa veya tepe havayolu basıncı ventilasyon sırasında >25 cm H2 O ise tüp bir büyük çapla değiştirilmiştir. En iyi uyan ETT DÇ'ı iÇ'a dönüştü- rülmüştür. En uygun iÇ, ETT değiştirme ihtiyacı, ultrasonografi ile havayolu çapı ölçüm süresi, ve tepe havayolu basınçları kaydedilmiştir. Bulgular: Ultrosonografi ile ilk deneme başarı oranı %86, ETT 5 hastada bir numara büyük olan, 2 hastada bir numara küçükle değiştirilmiştir. Sonuç: Bulgularımız USG ile ölçülen subglottic çapın uygun pediyatrik ETT çapının belirlenmesinde daha güvenilir bir belirleyici olduğunu göstermiştir.
