A newborn's head is very large in proportion to the body, and the cranium is enormous relative to his or her face. While the adult human skull is about one seventh of the total body length, the newborn's is about 1 ⁄ 4. Normal head circumference for a full-term infant is 33–36 cm at birth. [6]
The Apgar score is a quick way for health professionals to evaluate the health of all newborns at 1 and 5 minutes after birth and in response to resuscitation. [1] It was originally developed in 1952 by an anesthesiologist at Columbia University, Virginia Apgar, to address the need for a standardized way to evaluate infants shortly after birth.
Since there are differences in normal growth rates between breastfed and formula-fed babies, [2] the World Health Organization growth charts, which better reflect the growth pattern of the healthy, breastfed infant, are considered the standard for U.S. children under age two. [3]
With the infant lying supine, the examiner adjusts the infant's head to the midline and supports the infant's hand across the upper chest with one hand. The thumb of the examiner's other hand is placed on the infant's elbow. The examiner tries to pull the elbow gently across the chest, feeling for the resistance.
A score of 7–10 at 5 minutes is normal, a score of 4 to 6 at 5 minutes is intermediate, and a score of 0-3 is considered low. It is important to understand that an Apgar score is not a diagnosis, it is merely a clinical finding. [9] If a newborns score is 0–3, then resuscitation efforts are initiated. Apgar score for newborn infants
CPAM on chest radiograph in a newborn. Large cystic changes in the left lung, leading to a mediastinal shift to the right due to their mass effect. CPAMs are often identified during routine prenatal ultrasonography. Identifying characteristics on the sonogram include: an echogenic (bright) mass appearing in the chest of the fetus, displacement ...
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.
