Capurro Edad Gestacionalpdf (LATEST - EDITION)

Rationale: Skin changes dramatically with maturation. Preterm infants (24-34 weeks) have smooth, gelatinous skin. By term, the epidermis thickens and cracks appear. | Observation | Score | | :--- | :--- | | Flat, shapeless, little to no cartilage | 0 | | Incurved anthelix, soft cartilage that springs back slowly | 10 | | Well-defined anthelix, firm cartilage that springs back immediately | 20 |

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. Interpreting Results and Clinical Correlation | Capurro GA (weeks) | Clinical Category | | :--- | :--- | | < 34 | Very preterm / Moderate to late preterm | | 34 – 36 | Late preterm | | 37 – 38+6 | Early term | | 39 – 40+6 | Full term | | 41 – 41+6 | Late term | | ≥ 42 | Post-term |

Let’s break down each of the five items exactly as you would find in an official chart. Item 1: Skin Texture (Piel) | Observation | Score | | :--- | :--- | | Thick, cracked, superficial peeling | 0 | | Smooth, thin, red, translucent | 10 | | Medium thickness, moderate peeling, few veins | 20 | | Thick, parchment-like, deep cracks | 30 | capurro edad gestacionalpdf

[ \textGestational age (weeks) = \frac\textTotal Score + 2047 ]

Rationale: Breast tissue develops under the influence of maternal estrogens and fetal prolactin. Size correlates linearly with gestational age from 28 to 40 weeks. | Observation | Score | | :--- | :--- | | No creases, smooth anterior two-thirds | 0 | | Faint red marks or creases on the anterior half | 5 | | Clear creases on the anterior two-thirds | 10 | | Deep creases covering the entire sole | 15 | Rationale: Skin changes dramatically with maturation

Example: Total score = 80 80 + 204 = 284 → 284 / 7 = (approximately 40 weeks + 4 days).

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 | | Observation | Score | | :--- |

While obstetric ultrasounds provide the most accurate antenatal dating, millions of infants worldwide are born without reliable last menstrual period (LMP) data or first-trimester sonography. In these cases, clinicians must turn to postnatal physical and neurological maturity assessments. Among the various scoring systems developed over the past 50 years—including the Dubowitz, Ballard (and its New Ballard Score), and Eregie methods—one system stands out for its simplicity, speed, and validation in diverse populations: .
