Rationale: Ear cartilage hardens due to increased elastic fiber deposition after 33 weeks. This is a highly reliable physical sign. | Observation | Score | | :--- | :--- | | No palpable breast tissue (areola flat) | 0 | | Palpable nodule < 5mm diameter | 5 | | Palpable nodule 5 to 10mm diameter | 10 | | Palpable nodule > 10mm diameter | 15 |
Rationale: The soles are the last area to develop creases. At 28 weeks, they are smooth; by 40 weeks, they are fully creased. | Observation | Score | | :--- | :--- | | No recoil (arm remains extended) | 0 | | Slow or partial recoil (< 90°) | 10 | | Complete and brisk recoil (≥ 90°) | 20 | capurro edad gestacionalpdf
Capurro’s genius was in . He used a statistical technique called multiple logistic regression to identify the five most predictive signs of gestational age from a larger pool of variables. The result was a semi-objective scale that could be completed in less than three minutes. Rationale: Ear cartilage hardens due to increased elastic

Introduction In the high-stakes environment of neonatal care, knowing the exact gestational age (GA) of a newborn is not merely an administrative detail—it is a clinical necessity. Gestational age influences every critical decision, from resuscitation protocols at birth to the interpretation of neurological exams, nutritional plans, and the administration of surfactant or antibiotics.
Example: Total score = 80 80 + 204 = 284 → 284 / 7 = (approximately 40 weeks + 4 days).
If the infant has clinical signs of intrauterine growth restriction (weight < 10th percentile, head sparing, wasted appearance) or the mother had documented placental insufficiency, subtract 1 week from the calculated GA. This is because growth-restricted infants appear more mature neurologically and physically than their true age. Pro-tip: The official PDF scoring sheet includes a visual chart or nomogram to avoid manual division, but the formula above is standard.
