RESULTS
We included 17 PTB32W. Both groups were similar in terms of median
gestational age: 26 weeks (interquartile rank (IQR) 25-28) in the
responders group, and 27 weeks (IQR 25-29) in the other; but different
in median number of days on invasive mechanical ventilation: 27 (IQR
11-43) vs. 76 (IQR 35-117) in the non-responders group, p=0.03; and
number of infants with moderate-severe bronchopulmonary dysplasia: 2
(25%) vs. 8 (89%), p=0.005.
The responders group showed lower LU scores at one week after diuretics:
median LU score 3 (IQR 0-10) vs. 12 (IQR 12-12) in the non-responders
group, p=0.04; and after three weeks of treatment: median value 6 (IQR
3-6) in the responders group vs. 12 (10-15) in the non-responders group,
p=0.01. The decrease in RS was achieved since the beginning of
diuretics: 4 out of 8 (50%) were extubated in the responders group, and
8 out of 9 (11%) in the non-responders group, p=0.048.
