Resumo

EXPERIÊNCIA E OBJETIVOS: A via aérea por máscara laríngea (LMA), que tem sido utilizada frequentemente no tratamento das vias aéreas, pode causar lesão e morbidade na área laringofaríngea. Nesse estudo, comparamos as alterações macroscópicas nas estruturas laringofaríngeas e a morbidade laringofaríngea pós-operatória pelo uso da LMA Supreme® versus LMA ProSeal® em crianças. MÉTODOS: Dividimos os pacientes em dois grupos. Inserimos LMA ProSeal #3 no primeiro grupo e LMA Supreme #3 no segundo grupo. Antes da inserção da LMA e em seguida à sua remoção, fizemos laringoscopia direta nos pacientes. Comparamos entre os dois grupos: hiperemia, lesão de mucosa e as manchas de sangue por ocasião da remoção da LMA, e também o tempo de inserção, percentual de sucesso na inserção do tubo gástrico na primeira tentativa, náusea, vômito e dor de garganta. RESULTADOS: Não foram observadas diferenças significativas entre os dois grupos para tempo médio de operação, gênero, idade, peso, percentual de sucesso na inserção do tubo gástrico na primeira tentativa, náusea, vômito, dor de garganta e lesão de mucosa. O tempo médio de inserção para o grupo LMA ProSeal foi significativamente maior versus grupo LMA Supreme (p = 0,0001). O índice de manchas de sangue na remoção da LMA foi significativamente mais alto no grupo LMA ProSeal versus LMA Supreme (p = 0,034). Os pacientes que apresentaram manchas de sangue por ocasião da remoção da LMA exibiram hiperemia e lesão de mucosa significativamente mais expressivas versus pacientes com LMA limpa (p = 0,0001, p = 0,020). CONCLUSÃO: Em crianças, a inserção da LMA Supreme é mais rápida e fácil do que a inserção da LMA ProSeal; e, em comparação com LMA ProSeal, causa menos lesão laringofaríngea.

Abstract

BACKGROUND AND OBJECTIVES: Laryngeal mask airway (LMA), which has been used frequently in airway management, can cause laryngopharyngeal injury and morbidity. In this trial, we compare the macroscopic changes on laryngopharyngeal structures and the postoperative laryngopharyngeal morbidity by using LMA supreme with LMA proseal in children. METHODS: We divided patients into two groups. We inserted size three LMA proseal into the first group and size three LMA supreme into the second group. Before LMA insertion and after LMA removal, we performed direct laryngoscopy on the patients. We compared hyperemia, mucosal injury and blood staining on LMA removal, as well as insertion time, rate of success in gastric tube insertion on the first attempt, nausea, vomiting, and sore throat between the two groups. RESULTS: We recorded no significant differences between the two groups for mean operation time, sex, age, weight, rate of success in gastric tube insertion on first attempt, nausea, vomiting, sore throat and mucosal injury. Mean insertion time for the LMA proseal group was significantly longer than the LMA supreme group (p = 0.0001). The ratio of blood staining on LMA removal was significantly higher in the LMA proseal group than the LMA supreme group (p = 0.034). The patients with blood staining on LMA removal exhibited significantly more mucosal hyperemia and injury than the patients with clear LMA (p = 0.0001, p = 0.020). CONCLUSION: LMA supreme insertion is faster and easier than LMA proseal and causes less laryngopharyngeal injury than LMA proseal in children.
