Introduction: Low Birth Weight (LBW) represent a vulnerable group of newborns associated with high risk of complications thus have a high mortality rate. There are many factors affecting the early survival of LBW neonates. There are limited studies providing the evidence on survival predictors in the newborns in western Indian region.
Aim: To identify the various factors determining the survival of LBW newborns.
Materials and Methods: This was a prospective cohort study conducted in the Neonatal Intensive Care Unit (NICU) of the Department of Paediatrics, Jay Kay Lon Mother and Child Hospital, a neonatal and paediatric tertiary care centre attached to Government Medical College, Kota, India over a period from January 2011 to December 2011. Three hundred and sixty two newborns, admitted to the neonatal intensive care unit with birth weight <2500 gm within 24 hours of birth, were included in the study. Data were interpreted by using Statistical Package for Social Sciences (SPSS) Software for windows version 20.0. Those babies that were transferred and directly discharged to home were pooled as survivors and for the purpose of analysis were compared to babies that died during hospital stay. Associations between categorical variables and survival and death outcome were performed using the Chi-Square test. The p-value less than or equal to 0.05 was considered significant.
Results: This study of total sample of 362 newborns, reported a survival rate of 76.52% (277) and a mortality of 23.48% (85). Single gestation birth had better survival (78.69%) than multiple births (64.91%) (p=0.024). The survival improved as the birth weight increased (p<0.001). The survival in female was better (82.31%) as compared to males (72.56%) (p=0.032). The survival in Appropriate for Gestational Age (AGA) newborns was better (79.85%) than Small for Gestational Age (SGA) (67.68%) (p=0.0149). Neonates delivered to mothers who received antenatal steroids had a survival rate of 76.14% as compared to 68.13% in those who had not received steroids (p<0.02). Main cause of mortality in the study group was Respiratory Distress Syndrome (RDS) (86.36%) followed by Birth Asphyxia (BA) (33.33%) and Necrotising Enterocolitis (NEC) (33.33%).
Conclusion: The BA and RDS were the most common cause of neonatal mortality among various other complications related to prematurity and LBW. However, there are several factors that interplay and it is not possible to single out any particular factor influencing LBW survival. Reducing perinatal mortality requires a multidimensional approach with timely identification and appropriate management of the issues related to potential complications of prematurity as RDS, LBW and BA.
