Abstract

ABSTRACTPURPOSE: The i-gelTM is one of the second generation supraglottic airway devices. Our study was designed to compare the i-gel and the Laryngeal Mask Airway ClassicTM with respect to the clinical performance.METHODS: We compared the performance of the i-gel with that of the Laryngeal Mask Airway Classic in 120 patients undergoing urologic surgery during general anesthesia without muscle relaxant with respect to the number of attempts for successful insertion, insertion time, peak airway pressure, incidence of regurgitation, fiberoptic glottic view and postoperative complications. Second generation supraglottic airway devices were inserted by the same anesthesiologist, experienced in use of both devices (>200 uses and first time failure rate <5%). Methylene blue method was used to detect gastric regurgitation.RESULTS: There was no statistical difference between the two groups regarding the success of insertion of second generation supraglottic airway device (p = 0.951). The laryngeal mask insertion time for the i-gel group was significantly shorter than that for the Laryngeal Mask Airway Classic group (11.6 ± 2.4 s versus 13.1 ± 1.8 s [p = 0.001]). The fiberoptic glottic view scores for the i-gel group was significantly better than that for the ones for the Laryngeal Mask Airway Classic group (p = 0.001). On fiberoptic view, there was no sign of methylene blue dye at any time point in either group. In addition, there was no difference between the groups in patient response regarding the presence of a sore throat when questioned 24 h after the procedure (p = 0.752).CONCLUSION: Both devices had good performance with low postoperative complications and without occurrence of regurgitation. The i-gel provided a shorter insertion time and a better fiberoptic view than the Laryngeal Mask Airway Classic.

Resumo

RESUMOJUSTIFICATIVA E OBJETIVO: A i-gel é um dos dispositivos supraglóticos de segunda geração para o manejo das vias aéreas. Nosso estudo foi projetado para comparar a i-gelTM e a máscara laríngea clássica (Laryngeal Mask Airway ClassicTM, LMA-C) em relação ao desempenho clínico.MÉTODOS: Avaliamos os desempenhos de i-gel e LMA-C em 120 pacientes submetidos à cirurgia urológica sob anestesia geral sem relaxante muscular. Comparamos o número de tentativas de inserção bem-sucedidas, o tempo de inserção, a pressão de pico das vias aéreas, a incidência de regurgitação, a visibilidade da glote com o uso de fibra óptica e as complicações no pós-operatório. Os dispositivos supraglóticos de segunda geração foram inseridos pelo mesmo anestesiologista com experiência na aplicação de ambos os dispositivos (> 200 aplicações e taxa de falha na primeira tentativa < 5%). O corante azul de metileno foi usado para detectar regurgitação gástrica.RESULTADOS: Não houve diferença estatística entre os dois grupos em relação ao sucesso da inserção do dispositivo supraglótico de segunda geração (p = 0,951). O tempo de inserção da máscara laríngea no grupo i-gel foi significativamente menor do que no grupo LMA-C (11,6 ± 2,4 segundos vs. 13,1 ± 1,8 segundos, p = 0,001). O escore de visibilidade da glote via fibra óptica do grupo i-gel foi significativamente melhor do que o do grupo LMA-C (p = 0,001). Na visão via fibra ótica, sinais do corante azul de metileno não foram observados em qualquer momento em ambos os grupos. Além disso, não houve diferença entre as respostas dos grupos quando perguntados sobre a presença de dor de garganta 24 horas após o procedimento (p = 0,752).CONCLUSÃO: Ambos os dispositivos apresentaram bom desempenho, com poucas complicações no pós-operatório e sem ocorrência de regurgitação. A máscara laríngea i-gel proporcionou um tempo de inserção mais curto e uma visão via fibra óptica melhor do que a LMA-C.
