BACKGROUND AND OBJECTIVES: Mechanical ventilation incurs significant morbidity and mortality, weaning intensive care unit patients is highly desirable, although it is usually conducted in an empirical manner. Thus, this article assessed a weaning protocol implementation and compared two different methods. METHODS: It was carried out a study involving 120 patients who had received mechanical ventilation for more than 48 hours. These patients were randomly assigned to undergo one of two weaning techniques: pressure-support ventilation + PEEP (PSP) technique, which was applied to the patients in equal days, forming the PSP group (PSPG) and the T-tube method (TT), applied in odd days and forming the TT group (TTG). Standardized protocols were followed for each technique RESULTS: The patients response to extubation revealed similar progress in both PSP and TT groups, but after the Chi-square statistical test, the benefits of using a weaning protocol was clear. One hundred nine (90.83%) of all patients, had a successful weaning and any noninvasive ventilation type was needed in a span time of 24 hours after extubation, and only eleven (9.17%), had an unsuccessful weaning. CONCLUSIONS: Although this study didn't show any difference between the two methods applied, we could conclude that, the implementation of standardized weaning protocols can substantially decrease the patient's reintubation rate, promoting a downward trend in mortality and morbidity for these patients and shortening their hospital and intensive care units length of stay.
