Factors associated with failure in ventilatory weaning of children undergone pediatric cardiac surgery.
OBJECTIVE
To assess factors associated with failure in ventilatory weaning of children undergone surgical correction of congenital heart diseases.


METHODS
Cohort study with 29 children. The heart diseases were divided into cyanotic (nine children) and acyanotic (20 children). We studied children from 0 to 5 years who underwent heart surgery with invasive mechanical ventilation.


RESULTS
The failure group presented smaller value in SpO2 and higher values during days of stay in IMV and FiO2 when compared to the success group (P<0.05). It was observed that 4 children (14%) had failed in weaning, being necessary to return the ventilatory prosthesis before 48 hours after extubation.


CONCLUSIONS
The days of IMV, SpO2 and FiO2 were the main factors associated with failed extubation in this group of patients.
