Comparison of I-Gel and Auragain in Airway Management

Abstract

Objective: We aimed to compare the superiority of I-Gel and Auragain, the second-generation supraglottic airway devices (SGAD) with different cuff structures, in terms of speed and ease of placement, oropharyngeal leak pressure (OLP), resistance of gastric contents, and post-operative oropharyngeal pain. Materials and Methods: A total of 70 patients aged 18-65 years, with ASA scores I-II, who used I-Gel or Auragain to provide airways under general anesthesia were included in the study. Patients were divided into two groups as I-Gel and Auragain according to the type of SGAD used. Results: OLP, placement duration and Visual Analogue Score (VAS) were found to be statistically significantly higher in the Auragain group (p<0.05). In addition, a moderate positive correlation was found between VAS score and placement duration and number of attempts (p<0.05). Gastric decompression success was similar in both groups (p>0.05). Conclusion: The use of I-Gel provides faster airway and less postoperative throat ache. The use of Auragain provides more efficient ventilation and higher OLP values. In addition, throat ache increases with the number of attempts and the duration of placement in both groups.

Havayolu Yönetiminde I-Gel ile Auragain Kullanımının Karşılaştırılması

Öz

Amaç: Kaf yapıları birbirinden farklı olan ikinci nesil supraglottik havayolu araçları (SGAD)’ ndan I-Gel ve Auragain’in yerleştirme hızı ve kolaylığı, oluşturdukları orofaringeal kaçak basıncı (OKB), mide içeriğinin direnajı, post-operatif orofarinkste neden oldukları ağrı bakımından birbirlerine olan üstünlüklerini karşılaştırılmayı amaçladık. Materyal ve Metot: Çalışmaya 18-65 yaş arası, ASA skoru I-II olan, genel anestezi altında havayolu sağlanması için I-Gel veya Auragain kullanılan toplam 75 hasta dahil edildi. Hastalar kullanılan SGAD türüne göre I-Gel ve Auragain olarak iki gruba ayrıldı. Bulgular: OKB, yerleştirme süresi ve Vizüel Analog Skala (VAS) skorlarının Auragain grubunda istatistiksel olarak anlamlı düzeyde yüksek olduğu bulundu (p<0.05). Ayrıca VAS skoru ile yerleştirme süresi ve deneme sayısı arasında pozitif yönde orta düzey korelasyon saptandı (p<0.05). Her iki grubun mide dekompresyonu başarısı ise benzer bulundu (p>0.05). Sonuç: I-Gel kullanımı ile daha hızlı havayolu sağlanmakta ve daha az postoperatif boğaz ağrısı oluşmaktadır. Auragain kullanımı ise daha etkin ventilasyon ve daha yüksek OKB değeri sağlamaktadır. Ayrıca her iki grupta da deneme sayısı ve yerleştirme süresinin fazla olması ile boğaz ağrısı artmaktadır.
