Insights
Premature rupture of membranes (PROM) in neonates is linked to significant risks, including pneumonia and sepsis. Prompt intervention for high-risk infants with PROM and maternal disease is crucial for reducing mortality.
Area of Science:
- Neonatalogy
- Obstetrics
- Perinatology
Context:
- Maternal premature rupture of membranes (PROM) affects neonate development and outcomes.
- Neonatal intensive care units (NICUs) manage infants born after PROM.
- Understanding PROM complications is vital for neonatal care.
Purpose:
- To review clinical characteristics, evolution, complications, and mortality in neonates with maternal PROM.
- To identify risk factors for mortality in this vulnerable population.
- To compare incidence rates with existing literature.
Summary:
- This study analyzed 77 neonates with maternal PROM, noting an incidence of 25.8%. Key morbidities included nosocomial pneumonia (44.1%) and respiratory distress syndrome (39%).
- Maternal factors like infection and chorioamnionitis, prolonged membrane rupture (>24 hours), and cesarean delivery were common.
- Disease during pregnancy, vaginal birth, prematurity, and neonatal sepsis emerged as significant mortality risk factors.
Impact:
- Identified specific risk factors for mortality in neonates exposed to PROM, enabling targeted interventions.
- Highlights a higher incidence of PROM and neonatal sepsis than previously reported, underscoring the need for heightened awareness.
- Emphasizes the critical need for specialized care for premature neonates with PROM, especially those with co-existing maternal disease or sepsis.
Abstract:
The development of 77 neonates, with maternal premature membranes rupture in a neonatal intensive care unit was reviewed. Clinical characteristics, evolution, complications and mortality, as well as the risk factors for mortality were reviewed. The incidence was 25.8% in 298 neonates discharged, maternal age 25 + 6 years (X and standard deviation), number of gestations 2 + 1, maternal infection in 11 (14.2%), chorioamnioitis in 18 (23.3%), the ruptured membranes time was > 24 hours in 48%. Vaginal birth were 37.7%, and cesarean section 59.7%. Males predominated with 61%, gestational age 31 + 2 weeks, birth weight 1577 + 530. The three main morbidity causes were nosocomial pneumonia (44.1%), respiratory distress syndrome (39%), and intrauterine pneumonia (33.8%). By clinic and laboratory 3.8% neonates had septicemia, but only eight had some positive culture. Disease during pregnancy, vaginal birth, prematurity and neonatal sepsis were risk factors for mortality. Incidence of infants with PROM and neonatal sepsis is higher than majority of other reports. All premature neonates with PROM more; disease during pregnancy, vaginal birth, or neonatal sepsis, have high risk for mortality, then they need specially cares.
