A simple method of assessment of gestational age in newborn infants

Area of Science:

• Neonatal assessment
• Pediatric endocrinology
• Maternal-fetal medicine

Background:

• Accurate gestational age assessment is crucial for neonatal care and management.
• Existing methods may be time-consuming or require specialized equipment.
• A simple, rapid assessment tool is needed for clinical practice.

Purpose of the Study:

• To introduce and validate a straightforward method for determining gestational age in newborns.
• To evaluate the clinical utility and accuracy of this new assessment technique.

Main Methods:

• The method utilizes four easily observable physical characteristics: anterior vascular capsule of the lens, plantar creases, breast nodule, and ear firmness.
• Statistical analyses were performed to determine the reliability and confidence intervals of the method.

Main Results:

• The presented method provides a practical and useful assessment of gestational age.
• The 95% confidence limits for the gestational age estimation were found to be 11 days.
• The method is applicable to all newborn infants, including those who are sick, within the first 48 hours of life.

Conclusions:

• This simple four-characteristic method offers a valuable tool for rapid gestational age assessment in neonates.
• Its applicability to sick infants and within the initial 2 days of life enhances its clinical significance.
