Background: Neonatal morbidity and mortality continue to be major public health issues globally, especially for infants admitted to neonatal intensive care units (NICUs). This study aims to investigate the incidence of morbidities among neonates born to high-risk mothers and to evaluate the impact of various maternal risk factors on neonatal morbidity and mortality in the NICU setting.
Methods: This prospective observational study was conducted on 1,000 newborns up to 28 days of life, all with maternal risk factors, born in our tertiary care center, and admitted to the NICU.
Results: Most NICU admissions occurred during the 34-36 weeks of gestation, comprising 412 (41.20%) of the total admissions. Additionally, there was a female predominance, with 552 cases, representing 55.20% of the admissions. Most of the NICU patients came from rural background 594 (59.40%) and belonged to socioeconomic status (SES) IV 764 (76.40%). Higher percentages of neonatal morbidities were observed among children of illiterate and primarily educated mothers, amounting to 913 cases (91.30%). After evaluating patients in the NICU, we found that mortality was 172 (17.20%). Mothers with previous bad obstetric histories were at greater risk of poor neonatal outcomes. Cesarean sections were more commonly associated with NICU admissions, accounting for 555 cases (55.50%). The primary risk factors included pregnancy-induced hypertension, previous lower segment cesarean section, fetal distress, and premature rupture of membranes. Significant neonatal morbidities included respiratory distress syndrome (RDS) due to prematurity 79 (45.9%), intrauterine growth retardation 19 (11.0%), meconium aspiration syndrome 16 (9.3%), birth asphyxia, sepsis 29 (16.8%), and congenital anomalies 12 (6.9%). RDS was identified as the leading cause of morbidity.
Conclusion: The present study highlights several critical factors associated with NICU admissions and neonatal morbidities, underscoring the need for targeted interventions to improve neonatal health outcomes.
