Maternal transdermal nitroglycerin use and early childhood development

Area of Science:

• Obstetrics and Gynecology
• Neonatal Medicine
• Developmental Pediatrics

Background:

• Transdermal nitroglycerin (GTN) use in preterm labor has shown promise in reducing neonatal morbidity and mortality.
• Long-term developmental outcomes in children exposed to GTN in utero require thorough evaluation.

Purpose of the Study:

• To assess the one-year and two-year developmental performance of children born to mothers who received transdermal nitroglycerin (GTN) for preterm labor.
• To determine if maternal GTN treatment impacts child development across various domains.

Main Methods:

• A randomized, double-blind, placebo-controlled trial was conducted.
• Ages and Stages Questionnaires (ASQ) evaluated communication, motor skills, problem-solving, and social skills.
• Analyses included stratification by gestational age and assessment of normal/abnormal development.

Main Results:

• 111 children completed 12-month and 83 completed 24-month follow-ups.
• No significant differences in ASQ scores were found between the GTN and placebo groups at either time point.
• A non-significant trend towards fewer abnormalities in the GTN group at two years was noted.

Conclusions:

• Maternal transdermal nitroglycerin (GTN) for preterm labor does not appear to affect long-term child development.
• Larger studies are recommended to validate these preliminary developmental findings.
