Insights
Cardiorespiratory rates change after the first oral feeding in preterm infants, with variations noted based on gestational age and oral feeding skills. These findings are crucial for understanding infant feeding development.
Area of Science:
- Neonatal Physiology
- Pediatric Nutrition
Background:
- Preterm infants often face challenges with oral feeding.
- Understanding cardiorespiratory responses during early feeding is vital for clinical management.
Purpose of the Study:
- To correlate cardiorespiratory parameters with gestational age and oral feeding skills during the initial oral feeding experience in preterm infants.
Main Methods:
- 37 clinically stable preterm infants were studied.
- Cardiorespiratory rates were measured before and after the first oral feeding.
- Infants were stratified by gestational age and categorized by oral feeding skill level (I-IV).
Main Results:
- No significant baseline differences in heart or respiratory rates were found across gestational age strata or oral skill levels.
- Heart rate changes post-feeding differed between gestational age groups (30-33 vs. 34-36 weeks) and oral skill levels (I, II, IV).
- Respiratory rate changes post-feeding showed a difference only in infants with oral skill level I.
Conclusions:
- Pre- and post-prandial cardiorespiratory rates differ during the first oral feeding in preterm infants.
- These differences are associated with varying gestational ages at birth and levels of oral feeding skills.
Purpose:
To correlate cardiorespiratory parameters with gestational age and level of oral feeding skills in the first oral feeding in preterm infants.
Methods:
Study participants were 37 clinically stable preterm infants. Cardiorespiratory rate was assessed before and after introduction of oral feeding. The newborns were divided into three strata according to gestational age at birth. Oral skill was classified into four levels: I - low oral skill and low resistance to feeding; II - low oral skill and high resistance to feeding; III - high oral skill and low resistance to feeding; IV - high oral skill and high resistance to feeding.
Results:
No difference was observed in heart and respiratory rate between the strata of gestational age at birth and between the levels of oral skill. Comparison between pre- and post-cardiorespiratory rates within each level of oral skill and stratum of gestational age showed difference between heart rate in the strata of gestational ages of 30 to 33 weeks and of 34 to 36 weeks, as well as between oral skill of levels I, II, and IV. With regard to the comparison between pre- and post- respiratory rates, difference was found in the oral skill of level I.
Conclusion:
Differences were observed between pre- and post-prandial cardiorespiratory rates regarding the first oral feeding, as well as between strata of gestational age at birth and levels of oral feeding skills.
