ASSESSMENT AND CARE OF NEWBORNS IN
CLINICAL SETTINGS
Anatomy and Physiology of the Newborn
Cranial Anatomy and Cephalhematoma
The parietal areas of the skull are located behind the frontal
bone and form the top surfaces of the cranial cavity.
A cephalhematoma is a localized swelling that occurs in
these areas and does not cross suture lines, indicating a
specific type of injury during birth.
Understanding the anatomy is crucial for assessing
newborns for any cranial abnormalities or injuries.
The frontal area corresponds to the forehead and is
associated with the eyes, while the temporal area is located
behind the ears, and the occipital area is at the back of the
head.
Reflexes in Newborns
The tonic neck reflex, also known as the fencing reflex, is
observed when the newborn's head is turned to one side,
causing the arm on that side to extend and the opposite arm
to flex.
This reflex is present until about three months of age and is
a normal part of newborn development.
, The Moro reflex is a response to sudden changes in
equilibrium, characterized by the extension and abduction
of limbs followed by flexion.
The Babinski reflex involves the fanning of toes when the
sole of the foot is stroked, indicating neurological function.
Newborn Assessment Techniques
Apgar Score Evaluation
The Apgar score is a quick assessment tool used to evaluate
the health of newborns at 1 and 5 minutes after birth,
focusing on five criteria: heart rate, respiratory effort,
muscle tone, reflex irritability, and color.
Muscle tone is assessed alongside heart rate to determine
the newborn's overall condition.
The score helps in identifying the adequacy of the
newborn's transition to extrauterine life, particularly the
functioning of the cardiac and respiratory systems.
A low Apgar score may indicate the need for immediate
medical intervention.
Blood Sampling Techniques
The outer heel is the preferred site for obtaining blood
samples for metabolic testing in newborns due to its good
perfusion and quick healing.
Other sites like the big toe, foot pad, and inner sole are less
suitable for blood draws in infants.
