The Capurro Method is a clinical, somatic-based scale used in neonatology to estimate gestational age, particularly when menstrual history or early ultrasound data is unavailable. It evaluates physical signs—skin texture, ear shape, mammary gland size, nipple formation, and plantar creases—to calculate age, with a margin of error of ±plus or minus
8 to 9 days. For a detailed breakdown of the assessment parameters, see METODO DE CAPURRO.
The Capurro Method is a clinical technique used by neonatologists and pediatricians to estimate the gestational age of a newborn. It is particularly useful in resource-limited settings because it relies on physical examination and neurological signs rather than expensive equipment. Overview of the Capurro Method
Developed by Dr. Haroldo Capurro, this method evaluates specific physical and neurological characteristics to determine how many weeks a baby has been in the womb. There are two main versions:
Capurro A: Includes 4 physical signs and 2 neurological signs (used for healthy newborns).
Capurro B: Includes 5 physical signs (used when the baby is stressed, ill, or sedated, as neurological signs may be unreliable). Criteria and Scoring
Each parameter is assigned a score based on the level of development:
Skin Texture: Ranges from very thin and gelatinous to thick, wrinkled, or leathery.
Ear Shape: Assesses the degree of incurvation of the upper edge of the pinna (outer ear).
Mammary Gland Size: Measures the diameter of the breast tissue.
Nipple Formation: Evaluates the visibility of the areola and whether it is raised.
Plantar Creases: Checks for wrinkles on the sole of the foot (more creases indicate a more mature baby).
Neurological Signs (Capurro A only): Includes the "Scarf Sign" (arm position) and "Head Return" (neck muscle tone). Calculation Formula
To find the gestational age in days, the scores are added to a constant value and then divided by 7 to get the weeks: For Capurro B (Physical signs only):
Gestational Age (days)=∑Scores+2047Gestational Age (days) equals the fraction with numerator sum of Scores plus 204 and denominator 7 end-fraction Classification of Newborns Based on the result, newborns are categorized as: Preterm (Premature): Less than 37 weeks. Full Term: 37 to 41 weeks and 6 days. Post-term: 42 weeks or more. Resources and PDF Guides

The Capurro Method is a clinical standard used in neonatology to estimate the gestational age of a newborn when prenatal data, like the date of the last menstrual period or early ultrasounds, are unavailable or unreliable. Developed by Dr. Haroldo Capurro, this clinical assessment relies on physical characteristics and neurological signs to determine how many weeks a baby has spent in the womb.
For medical professionals and students, having a Capurro Method PDF is an essential resource for quick reference in the delivery room or neonatal intensive care unit (NICU). What is the Capurro Method?
The Capurro Method is specifically designed for newborns who are not under severe distress. It provides an estimate of gestational age with a margin of error of approximately ±8.4plus or minus 8.4
days. This tool is vital for classifying a newborn as preterm, full-term, or post-term, which dictates the immediate level of care required. Evaluation Criteria
There are two main variations of the Capurro Method: Capurro A (physical and neurological) and Capurro B (physical only). Most clinical settings utilize the physical parameters for their speed and ease of use. Physical Parameters (Somatometric)
Skin Texture: Ranges from very thin and gelatinous (0 points) to thick, leathery, and wrinkled (20 points). capurro edad gestacionalpdf
Ear Shape (Pinna): Assesses the degree of incurving of the upper edge of the ear.
Breast Gland Size: Measures the palpable diameter of the breast tissue.
Nipple Formation: Evaluates the visibility and diameter of the areola.
Plantar Creases: Checks for the presence and depth of creases on the soles of the feet. Neurological Parameters (Used in Capurro A)
Scarf Sign: The position of the elbow relative to the midline when the arm is pulled across the chest.
Head Return: The ability of the infant to bring the head back to a vertical position from a tilted one. How to Calculate Gestational Age
To find the gestational age using the Capurro B (Physical) method, use the following formula:
Gestational Age (Days)=Total Score+2047Gestational Age (Days) equals the fraction with numerator Total Score plus 204 and denominator 7 end-fraction
The constant 204 is the mathematical adjustment used to align the clinical score with the actual number of days. Dividing by 7 converts the final result into weeks. Why Use a Capurro Method PDF?
Accessing a Capurro Method guide on platforms like ResearchGate or academic repositories is beneficial for:
Accuracy: Visual charts in PDFs help clinicians correctly identify the stages of ear curving or skin texture.
Standardization: Ensures all staff members are using the same scoring system.
Portability: Many practitioners keep a digital version on tablets or printed in clinical folders for immediate bedside use. Classification of the Newborn
Once the age is calculated, the newborn is typically classified as follows: Preterm: Less than 37 weeks. Full-term: Between 37 and 41 weeks. Post-term: 42 weeks or more.
While more modern methods like the Ballard Score are often used for very premature infants, the Capurro Method remains a fundamental, reliable tool for most clinical assessments of newborn maturity.
What is the Capurro method?
The Capurro method is a clinical assessment tool used to estimate the gestational age of newborns. It was developed by Dr. Fernando Capurro and colleagues in the 1970s. The method evaluates a newborn's physical and neurological maturity to estimate gestational age.
Components of the Capurro assessment:
The Capurro assessment consists of two main components:
How to perform the Capurro assessment:
To perform the Capurro assessment, follow these steps:
Capurro scoring system:
The Capurro scoring system assigns a score of 0, 1, or 2 for each characteristic, with 2 being the most mature. The scores are then added up to obtain a total score, which ranges from 0 to 34. The Capurro Method is a clinical, somatic-based scale
Interpretation of results:
The total score is used to estimate the gestational age. The estimated gestational age can be calculated using a chart or formula.
Limitations and considerations:
The Capurro method has some limitations and considerations:
Example of Capurro assessment:
Here is an example of a Capurro assessment:
| Characteristic | Score | | --- | --- | | Skin texture | 1 | | Lanugo | 0 | | Plantar creases | 1 | | Breast tissue | 1 | | Ear form | 1 | | Genital development | 1 | | Posture | 1 | | Square window | 1 | | Arm recoil | 1 | | Leg recoil | 1 | | Heel to ear reflex | 1 | | Total score | 10 |
Using a Capurro chart or formula, a total score of 10 may correspond to an estimated gestational age of 32-34 weeks.
Keep in mind that this is a simplified example, and the Capurro assessment should be performed by a trained healthcare professional.
The Capurro Method is a clinical technique used in neonatology to estimate the gestational age of a newborn, specifically within the first 48 hours of life. Developed by Dr. Haroldo Capurro in 1978, it is particularly valuable when the last menstrual period (LMP) is unknown or early ultrasounds are unavailable. Assessment Parameters
The method evaluates five physical (somatic) characteristics and, in some versions, two neurological signs:
Skin Texture: Ranges from very thin and gelatinous to thick with deep cracks.
Ear Shape (Pinna): Evaluates how much the edge of the ear is curved or folded.
Mammary Gland Size: Measures the diameter of the palpable breast tissue.
Nipple Formation: Assesses the visibility and size of the areola.
Plantar Creases: Examines the depth and distribution of creases on the sole of the foot. Calculation Variants There are two main ways to calculate the final age:
Capurro A (Somatic-Neurological): Used for healthy newborns; it includes the 5 physical parameters plus 2 neurological signs (the scarf sign and head lag). Formula:
Total Score+2007the fraction with numerator Total Score plus 200 and denominator 7 end-fraction
Capurro B (Somatic Only): Primarily used if the baby is stressed or ill, making neurological testing difficult. Formula:
Total Score+2047the fraction with numerator Total Score plus 204 and denominator 7 end-fraction Clinical Classification
Based on the calculated weeks, newborns are categorized as follows: Post-mature: 42 weeks or more. Full-term: 37 to 41 weeks. Mildly Preterm: 35 to 36 weeks. Moderately Preterm: 32 to 34 weeks. Extremely Preterm: Less than 32 weeks.
While the Capurro Method is a reliable bedside tool with a margin of error of approximately ±8plus or minus 8
days, first-trimester ultrasound remains the Gold Standard for gestational age accuracy. Skin texture and appearance Lanugo (fine hair) presence

The Dubowitz method is considered the most comprehensive clinical method, utilizing 21 criteria. However, it is time-consuming (taking up to 15-20 minutes) and complex to perform in a busy delivery room. Capurro streamlined the process, arguing that fewer criteria allowed for faster assessment without significant loss of accuracy, making it more practical for obstetricians and pediatricians in delivery units.
