Determinação do volume de ar no "cuff" de sondas endotraqueais

Abstract: RESUMO: O obj etivo deste estudo foi determinar o melhor ajuste do volume de ar a ser insuflado no 11 cuff" de diferentes diâmetros de cânulas endotraqueais de alto volume residual e baixa pressão, mantendo a pressão exercida pelo balonete na mucosa da traquéia entre os limites preconizados de 20 a 30 mmHg (menor que a pressão capilar da traquéia). Para tanto, foram insuflados 10 ml de ar no "cuff" de cânulas de pacientes intubados com diferentes diâmetros internos (7,0 -7,5 -8,0 -8,5 -9,0), mensurando, uma a … Show more

“…Some experimental and clinical trials 13,21,27,28 mention that cuffs should be inflated until there is no longer air leakage, in line with our study. However, none of them describes how to perform the procedure.…”

“…We do not agree with the movement, because the cuff should not fix the tube to the trachea. Other authors 27 have carried out a study to estimate cuff air volume needed for different tube sizes, in a way that pressure would never be higher than 20 to 30 mmHg. We believe that this volume depends on the ratio between internal tracheal diameter and external tube diameter.…”

“…Some studies (32)(33)(34) indicates that cuff inflation must be carried out until there is complete occlusion of the pathway and no air leaks. However, others (35,36) show that it is essential to control the cuff pressure.…”
