Survey of one month mortality and morbidity of infants less than 1500 grams admitted to NICU of Shahid Akbarabadi Hospital in Tehran in 1395

Neonates weighing less than 1500 grams (VLBW) consider nearly 4-7% of live births.  VLBW infants are more likely to be hospitalized due to their complications. The aim of this study is  to determine the rate of recovery, complications and predictive factors of VLBW neonate’s mortality. A cross-sectional study in NICU of Shahidakbar-Abadi Hospital in Tehran during the year 1395 was performed on all infants born with birth weight less than 1500 grams. Neonates were examined for one month from birth to discharge or expulsion or death. And information about mother and baby was extracted from medical records. Of the 9903 live births in Akbarabadi Hospital in Tehran in 1395, 264 VLBW newborns were included in the study. The survival rate was 75% (198) in this study. This study evaluated the prevalence of morbidities such as RDS, PDA , ROP , IVH, NEC, BPD, sepsis and pneumothorax. The most important morbidity in this study considered RDS. The most important factors of mortality in this study were RDS (P <0.001), PDA (P = 0.006), sepsis (P <0.001), IVH (P = 0.02), and pneumothorax (P <0.001), respectively. Considering the higher rate of survival in this study comparing with previous studies in Iran, this study shows improvement in neonatal care of VLBW infants in NICU.
