Comparison of the Laryngeal Mask Airway (CTrachTM) and Direct Coupled Interface-Video Laryngoscope for Endotracheal Intubation: a Prospective, Randomized, Clinical Study

Abstract

Objective: Video laryngoscopy was developed to facilitate tracheal intubation of difficult airways. We aimed to compare the efficacy of CTrach™ (CT) and Direct Coupled Interface-Videolaryngoscope (DCI-VL) in patients with normal airways. Material and Methods: Sixty ASA I–II (American Society of Anesthesiologists) adult patients admitted for elective surgery were enrolled in this prospective study. The patients were randomly assigned to two groups, where intubation was performed via CT or DCI-VL. Time to obtain a good glottic view, total intubation time, success rates and the number of patients who required maneuvers for a good glottic view were recorded. Results: The mean time to obtaining a good glottic view was significantly longer with CT than with DCI-VL (29.4±20.3 seconds vs. 12.8±1.9 seconds, respectively; p=0.01). Intubation was achieved on the first attempt in 28 patients in the CT group (93.3%) and in 24 in the DCI-VL group (80%) (p=0.77). The total intubation time for CT was significantly longer compared to DCI-VL (99.9±36.0 seconds vs. 39.2±21.4 seconds, respectively; p=0.01). Optimization maneuvers were required in eight and two patients in the CT and DCI-VL groups, respectively (p=0.03). Conclusion: Although the normal airway endotracheal intubation success rates were similar in both groups, the time to obtain a good glottic view and the total intubation time were significantly shorter with DCI-VL. Turkish Anahtar Kelimeler: CTrach, video laringoskop, havayolu yönetimi Amaç: Video laringoskopi zor hava yolunda trakeal entubasyonu kolaylaştırmak amacıyla geliştirilmiştir. Bu çalışmada CTrach™ (CT) ve Direct Coupled Interface-Videolariyngoskopun (DCI-VL) normal hava yoluna sahip hastalarda etkinliklerinin karşılaştırılması amaçlanmıştır. Materyal metod: Bu çalışmaya elektif cerrahi planlanan, 60 ASA (American Society of Anesthesiologists) I-II yetişkin hasta dahil edildi. Hastalar rastgele, entübasyonun CT veya DCI-VL aracılığıyla yapılacaklar olmak üzere iki gruba ayrıldı. İyi glottik görüntü elde etme süresi, total entübasyon süresi, entübasyon başarı oranları ve iyi glottik görüntü elde etmek için manevraya ihtiyaç duyulan hastalar kaydedildi. Bulgular: CT ile iyi glottik görüntü elde etmek için gereken süre DCI-VL' tan anlamlı olarak uzundu (29.4±20.3 saniye, 12.8±1.9 saniye; p=0.01). İlk denemede entübasyon, CT grubunda 28 hastada (%93.3), DCI –VL grubunda 24 hastada (%80) gerçekleşti (p=0.77). Total entübasyon süresi CT de, DCI- VL ile karşılaştırıldığında anlamlı olarak daha uzundu (99.9±36.0 saniye, 39.2±21.4 saniye, p=0.01). CT grubunda 8, DCI- VL grubunda ise 2 hastada optimizasyon manevraları gerekti (p=0.03). Sonuç: Normal hava yolu olan hastalarda endotrakeal entubasyon başarı oranları her iki grupta da benzer olmasına rağmen, iyi glottik görüntü elde etme süresi ve total entübasyon süresi DCI-VL de anlamlı olarak kısadır.
