Profile of reintubated patients submitted to daily weaning screen and spontaneous breathing trial in a general ICU

Mechanical ventilation (MV) weaning is the transition of artificial ventilation to spontaneous breathing of patients intubated for more than 24 hours. Reintubation may occur, even if the weaning process has been well conducted, in 13 to 19% of the extubated patients. Daily weaning screen and spontaneous breathing trial are widely used to evaluate patients ready to be weaned, although a reintubation risk may occur [ 1 ]. The objective of this study was to verify the profile of patients that failed the weaning process and needed to be reintubated.
