Insights
Small for gestational age (SGA) preterm infants with delayed stool passage had higher mortality rates than appropriate for gestational age (AGA) infants, despite similar gastrointestinal morbidity. This highlights a critical risk in SGA neonates.
Area of Science:
- Neonatalogy
- Pediatric Gastroenterology
- Perinatal Medicine
Background:
- Delayed stool passage in preterm infants is linked to gestational immaturity and illness severity.
- Small for gestational age (SGA) preterm infants face elevated risks for gastrointestinal (GI) complications.
- A strict nutrition and stool protocol was implemented to manage GI issues in preterm infants.
Purpose of the Study:
- To analyze the impact of a strict nutrition and stool protocol on GI problems.
- To compare GI complications and outcomes in SGA versus appropriate for gestational age (AGA) preterm infants with delayed meconium passage.
Main Methods:
- Retrospective cohort analysis of preterm infants with delayed meconium passage.
- Data collected from 2001-2009 at the Neonatal Intensive Care Unit of the Medical University of Graz, Austria.
- Comparison of neonatal morbidity, surgical intervention, and mortality rates between SGA and AGA infants.
Main Results:
- Twenty-six SGA infants (median GA 28.6 weeks) were compared to 101 AGA infants (median GA 28.4 weeks).
- No significant differences were observed in clinical signs of delayed meconium passage, necrotizing enterocolitis, ileus, spontaneous intestinal perforation, or surgical intervention.
- Mortality rate was significantly higher in SGA infants (11.5%) compared to AGA infants (2.9%, P=0.03).
Conclusions:
- SGA preterm infants with delayed meconium passage experienced similar GI morbidity as AGA infants.
- However, SGA infants demonstrated significantly higher rates of lethal complications.
- This underscores a critical vulnerability in SGA neonates requiring careful monitoring and management.
Objective:
Delayed passage of stool is a result of both gestational immaturity and illness severity. Small for gestational age (SGA) preterm infants are at high risk of gastrointestinal (GI) complications. We aimed to analyse the effects of a strict nutrition and stool protocol on GI problems in SGA compared to appropriate for gestational age (AGA) preterm infants.
Methods:
Retrospective cohort analysis including all preterm infants with delayed meconium passage hospitalized at the Neonatal Intensive Care Unit of the Medical University of Graz, Austria. Infants were identified by a local data system and by the use of a strict feeding and stool protocol between 2001 and 2009. Main outcome parameters included neonatal morbidity, surgical intervention and mortality.
Findings:
Twenty-six SGA (median GA 28.6 weeks, birth weight 825 grams, 46% males) were compared to 101 AGA (median GA 28.4 weeks, birth weight 1168 grams, 55% males) preterm infants. Clinical signs of delayed meconium passage did not differ significantly between groups. Differences regarding percentage of necrotizing enterocolitis, ileus, spontaneous intestinal perforation, and surgical intervention did not differ between groups. Mortality rate was significantly higher in SGA (11.5%) compared to AGA (2.9%) infants (P=0.03).
Conclusion:
Despite similar morbidity SGA infants exhibited higher lethal complication rates following delayed meconium passage compared to AGA infants.
