There was no statistically significant difference in reintubation rate ( noninvasive positive-pressure ventilation group , 9.1 % ; inhaled oxygen group , 11.3 % ; p > 0.05 ) and length of stay ( days ) in PICU ( noninvasive positive-pressure ventilation group , 3 [ 1-16 ] ; inhaled oxygen group , 2 [ 1-25 ] ; p > 0.05 ) or hospital ( noninvasive positive-pressure ventilation group , 19 [ 7-141 ] ; inhaled oxygen group , 17 [ 8-80 ] ) .
