3.1 Demographic characteristics (Table 1)
50 patients were enrolled into our study, out of which 7 children were
reintubated within 48 hours of extubation (group 1). The patients in
group 1 were younger in age compared to group 2, median age 1 (0.25-7)
year vs 3(0.25-17) years; p=0.040, and an age less than 1.5 years
correlated with weaning failure with a sensitivity of 71% and
specificity of 68%. The study groups were comparable with respect to
their sex, basal metabolic index (BMI), surgical procedures performed,
minimum intraoperative temperature, CPB and aortic cross clamp times
fluid balance at the end of CPB and before extubation in ICU and
echocardiographic parameters. The MV duration was significantly
prolonged in-group 1 (23.50 hours vs. 13 hours, p=0.019) and had more
frequent use of non – invasive ventilation (NIV) (42.8% vs. 7%,
p=0.029). The total ICU stay days was significantly longer in-group 1 (9
days vs 3 days, p = 0.02).
