The mean of the gestational age of neonates in Beraksurf and BLES surfactant groups were 31.64 ± 1.69 weeks and 31.03 ± 1.96 weeks and the difference was not significant (
Baseline and Demographic Information* P−value was calculated using chi−2 statistic test at 95% level of confidence interval and independent t−testThe mean time to receive surfactant was 4.49 ± 1.18 h in Beraksurf group and 4.24 ± 1.09 in BLES group. Time of receipt of surfactant in Beraksurf group was ≤ 12 h in 35 (54.7%), 2–12 h in 25 (39.1%) and ≥ 12 h in 4 (6.2%) neonates. In BLES group, it was ≤ 12 h in 35 (54.7%), 2–12 h in 27 (42.2%), and ≥ 12 h in 2 (3.1%) neonates. There was no significant difference between the mean post-natal age of surfactant administration in both groups (The mean days of hospital stay were 17.66 ± 1.46 days and 16.68 ± 1.46 days in Beraksurf and BLES groups respectively; however, this difference was not significant (Table
