Premature Infants Conceived with Assisted Reproductive Technology: An Analysis of Infant Morbidity, Compared with...

Area of Science:

• Neonatal care
• Reproductive medicine
• Perinatal outcomes

Background:

• Assisted reproductive technology (ART) is increasingly used for conception.
• Understanding the neonatal morbidity associated with ART is crucial for clinical practice.
• Premature infants, particularly those born between 30 to 34 weeks' gestational age, face significant health challenges.

Purpose of the Study:

• To evaluate and compare the morbidity of infants born via ART with matched naturally conceived infants.
• To identify specific areas of increased healthcare needs in ART-conceived neonates.
• To inform clinical decision-making regarding the management of ART pregnancies, especially concerning early delivery.

Main Methods:

• Retrospective review of maternal and infant data.
• Inclusion of inborn infants conceived via ART and matched control infants.
• Matching criteria included gestational age (30-34 weeks), gender, race, and multiple gestations.
• Statistical analysis using paired t-test, Wilcoxon-Mann-Whitney test, and Fisher's exact test.

Main Results:

• Infants conceived via ART (n=60) demonstrated increased requirements for respiratory support compared to naturally conceived infants (n=60).
• ART infants experienced longer durations to achieve full enteral feeding.
• No significant differences were noted in other measured parameters, but trends suggested higher resource utilization in the ART group.

Conclusions:

• Neonates born via ART exhibit greater physiological immaturity compared to naturally conceived infants of similar gestational age.
• These infants present with higher intensive care needs, potentially leading to increased healthcare costs.
• The physiological immaturity of ART infants should be a key consideration when planning early delivery in these pregnancies.
