Nutritional practices and outcome of extremely premature infants
Insights
For extremely low-birth-weight infants, parenteral nutrition increases risks for growth delay and infections. Enteral nutrition is generally recommended, but prospective studies are needed to confirm optimal feeding strategies.
Area of Science:
- Neonatalogy
- Pediatric Nutrition
- Perinatal Medicine
Background:
- Extremely low-birth-weight (ELBW) infants face significant risks of mortality and morbidity.
- Optimizing nutritional support is crucial for ELBW infant outcomes.
- Identifying specific risk factors for subacute complications is essential for improving care.
Purpose of the Study:
- To identify independent risk factors for subacute mortality and morbidity in ELBW infants surviving over seven days.
- To investigate the impact of parenteral nutrition (PN) versus enteral nutrition (EN) on ELBW infant outcomes.
- To analyze the role of nutrition timing and type in necrotizing enterocolitis (NEC) and chronic lung disease (CLD).
Main Methods:
- Analysis of records from 182 ELBW infants (birth weight < 1000 g) surviving >7 days.
- Logarithm-linear modeling to identify complex interactions and minimize confounding factors.
- Comparison of outcomes between infants receiving PN and EN, and analysis of EN initiation timing.
Main Results:
- Independent risk factors for subacute mortality included nosocomial infection, necrotizing enterocolitis, male gender, and chronic lung disease (CLD).
- Male gender and CLD increased mortality risk specifically in infants receiving PN.
- PN was associated with delayed growth, nosocomial infection, and CLD compared to EN.
- Delayed EN initiation reduced NEC risk in specific male ELBW infants (<775 g).
Conclusions:
- Parenteral nutrition poses risks for ELBW infants, including delayed growth and increased infection rates.
- Enteral nutrition is generally favored, but specific indications for withholding EN require further investigation.
- Prospective studies are needed to establish optimal guidelines for PN use and EN initiation in very-very-low-birth-weight infants.
Abstract:
We analyzed the records of 182 newborns with birth weights under 1000 g, who survived longer than seven days, to determine risk factors for subacute mortality and morbidity. Statistical analysis using logarithm-linear modeling was used to identify complex interactions and to minimize confounding. Nosocomial infection, necrotizing enterocolitis, male gender, and chronic lung disease (CLD) were identified as independent risk factors for subacute mortality. Male gender and CLD were associated with increased mortality only among patients who received parenteral nutrition (PN). Moreover, PN, rather than enteral nutrition (EN), was a risk factor for delayed growth, nosocomial infection, and CLD. Delayed initiation of EN was associated with decreased necrotizing enterocolitis risk only among male infants with birth weights under 775 g. Our results do not support elective withholding of EN in other groups of extremely low-birth-weight infants. We conclude that indications for PN and for withholding initiation of EN in very-very-low-birth-weight infants need to be established by prospective studies.
