Eficácia dos índices preditivos no desmame da ventilação mecânica

Abstract

The mechanical ventilation is associated a series of complications, and for that reason it should be discontinued the most precocious as possible. The importance of the indexes of prediction is to avoid the unnecessary prolongation so much in the use of the mechanical ventilation and delay of the weaning, as for the precocious interruption of the ventilatory support and fail in the desintubation. The predictors more frequently used were: CV; VC; P0,1; FR; Pimax; rapid shallow breathing index (FR/VC); P0,1/Pimax; P0,1 x FR/VC; oxygenation index (PaO2/FiO2); A+B+G score; CROP score; efficiency of the cough; amount of lung secretion; APACHE II. Several studies emphasize the importance of the predictive result, with the objective of avoiding harmful consequences in the attempts flaws in it weans him/it. On the other hand, the precision of the predictors has the potential of quickly to identify the patients that are capable for the spontaneous breathing trial, and like this accelerating the process of liberation of the mechanical ventilation, however until that moment consensus doesn't exist regarding the significant superiority of any of them in the obtaining of the final result.
