7. The Newborn



The Newborn


Care Management: From Birth Through The First 2 Hours



ent Care begins immediately after birth and focuses on assessing and stabilizing the newborn’s condition. As part of Standard Precautions, gloves are worn when handling the newborn until blood and amniotic fluid are removed by bathing.


ent The nurse verifies that respirations have been established, dries the infant, and assesses temperature.


ent Identical identification bracelets are placed on the infant and the mother. In some settings the father or partner also wears an identification bracelet. Information on the bracelet includes name, sex, date and time of birth, and identification number. Infants are footprinted by using a form that includes the mother’s fingerprints, name, and date and time of birth. These identification procedures must be performed before the mother and infant are separated after birth.


ent The infant can be placed on the mother’s chest or abdomen to allow skin-to-skin contact, wrapped in a warm blanket and placed in the mother’s arms, given to the partner to hold, or kept partially undressed under a radiant warmer. The infant can be admitted to a nursery or remain with the parents throughout the hospital stay.


ent The initial examination of the newborn can occur while the nurse is drying and wrapping the infant, or observations can be made while the infant is lying on the mother’s chest or abdomen or in her arms immediately after birth. Interference in the initial parent-infant acquaintance process should be minimized.


Apgar Score



ent The nurse usually assigns the Apgar score at 1 and 5 minutes after birth. The Apgar score permits a rapid assessment of the newborn’s transition to extrauterine life based on five signs (Table 7-1). Scores of 0 to 3 indicate severe distress; scores of 4 to 6 indicate moderate difficulty; and scores of 7 to 10 indicate that the infant is having no difficulty adjusting to extrauterine life. If resuscitation is required, it should be initiated before the 1-minute Apgar score.



Initial Physical Assessment



ent If the infant is breathing effectively, is pink, and has no apparent life-threatening anomalies or risk factors requiring immediate attention (e.g., infant of a mother with diabetes), delay further examination until after the parents have had an opportunity to interact with the infant. Routine procedures and the admission process can be carried out in the mother’s room or in a separate nursery.


ent The initial physical assessment includes a brief review of systems:


1. External: Note skin color, general activity, and position; assess nasal patency by covering one nostril at a time while observing respirations; assess skin for peeling or lack of subcutaneous fat (dysmaturity or postterm); note meconium staining of cord, skin, fingernails, or amniotic fluid (staining can indicate fetal release of meconium, often related to hypoxia; offensive odor can indicate intrauterine infection); note length of nails and creases on soles of feet.


2. Chest: Auscultate apical heart for rate and rhythm, heart tones, and presence of abnormal sounds; note character of respirations and presence of crackles or other adventitious sounds; note equality of breath sounds by auscultation.


3. Abdomen: Observe characteristics of abdomen (rounded, flat, concave) and absence of anomalies; auscultate bowel sounds; note number of vessels in cord.


4. Neurologic: Check muscle tone; assess Moro and suck reflexes; palpate anterior fontanel; note by palpation the presence and size of the fontanels and sutures.


5. Genitourinary: Note external sex characteristics and any abnormality of genitalia; check anal patency and presence of meconium; note passage of urine.


6. Other observations: Note gross structural malformations obvious at birth that require immediate medical attention.


ent A gestational age assessment is done within 2 hours of birth using forms readily available in nurseries.


ent An assessment of newborn reflexes (Table 7-2) and a more comprehensive physical assessment (Table 7-3) are completed within 24 hours of birth.



TABLE 7-2


Assessment of Newborn’s Reflexes


















































































































Reflex Eliciting the Reflex Characteristic Response Comments
Rooting and sucking Touch infant’s lip, cheek, or corner of mouth with nipple Infant turns head toward stimulus, opens mouth, takes hold, and sucks Response difficult if not impossible to elicit after infant has been fed; if response weak or absent, consider prematurity or neurologic defect Parental guidance: avoid trying to turn head toward breast or nipple, allow infant to root; response disappears after 3-4 mo but can persist upto 1 yr
Swallowing Feed infant; swallowing usually follows sucking and obtaining fluids Swallowing usually coordinated with sucking and usually occurs without gagging, coughing, or vomiting If response is weak or absent, may indicate prematurity or neurologic defect Sucking and swallowing often uncoordinated in preterm infant
Grasp:      
 Palmar Place finger in palm of hand Infant’s fingers curl around examiner’s fingers Toes curl downward Palmar response lessens by 3-4 mo; parents enjoy this contact with infant; plantar response lessens by 8 mo
 Plantar Place finger at base of toes Toes curl downward  
Extrusion Touch or depress tip of tongue Newborn forces tongue outward Response disappears about fourth mo of life
Glabellar (Myerson) Tap over forehead, bridge of nose, or maxilla of newborn whose eyes are open Newborn blinks for first four or five taps Continued blinking with repeated taps consistent with extrapyramidal disorder
Tonic neck or “fencing” With infant falling asleep or sleeping, turn head quickly to one side With infant facing left side, arm and leg on that side extend; opposite arm and leg flex (turn head to right, and extremities assume opposite postures) Responses in leg are more consistent Complete response disappears by 3-4 mo, incomplete response may be seen until third or fourth yr After 6 wk, persistent response is sign of possible cerebral palsy

Moro Hold infant in semisitting position, allow head and trunk to fall backward to an angle of at least 30 degrees Place infant on flat surface, strike surface to startle infant Symmetric abduction and extension of arms are seen; fingers fan out and form a C with thumb and forefinger; slight tremor may be noted; arms adducted in embracing motion and return to relaxed flexion and movement Legs may follow similar pattern of response Preterm infant does not complete “embrace”; instead, arms fall backward because of weakness Response is present at birth; complete response may be seen until 8 wk; body jerk is seen only between 8 and 18 wk; response absent by 6 mo if neurologic maturation is not delayed; response may be incomplete if infant is deeply asleep; give parental guidance about normal response Asymmetric response may connote injury to brachial plexus, clavicle, or humerus Persistent response after 6 mo indicates possible brain damage

Stepping or “walking” Hold infant vertically, allowing one foot to touch table surface Infant will simulate walking, alternating flexion and extension of feet; term infants walk on soles of their feet, and preterm infants walk on their toes Response normally present for 3-4 wk

Crawling Place newborn on abdomen Newborn makes crawling movements with arms and legs Response should disappear about 6 wk of age
Deep tendon Use finger instead of percussion hammer to elicit patellar, or knee-jerk, reflex; newborn must be relaxed Reflex jerk present; even with newborn relaxed, nonselective overall reaction can occur  
Crossed extension Infant should be supine; extend one leg, press knee downward, stimulate bottom of foot; observe opposite leg Opposite leg flexes, adducts, and then extends as if attempting to push away stimulating agent This reflex should be present during newborn period

Babinski (plantar) On sole of foot, beginning at heel, stroke upward along lateral aspect of sole, then move finger across ball of foot All toes hyperextend, with dorsiflexion of big toe; recorded as a positive sign Absence requires neurologic evaluation, should disappear after 1 yr of age

Pull-to-sit (traction) Pull infant up by wrists from supine position with head in midline Head will lag until infant is in upright position, then will be held in same plane with chest and shoulder momentarily before falling forward; infant will attempt to right head Response depends on general muscle tone and maturity and condition of infant
Trunk incurvation (Galant) Place infant prone on flat surface, run finger down back about 4-5 cm lateral to spine, first on one side and then down other Trunk is flexed, and pelvis is swung toward stimulated side With transverse lesions of cord, no response below the level of the lesion is present Response disappears by fourth wk
Absence suggests general depression of nervous system
Response can vary but should be obtainable in all infants, including preterm ones

Magnet Place infant in supine position, partially flex both lower extremities, and apply pressure to soles of feet Both lower limbs should extend against examiner’s pressure Absence suggests damage to spinal cord or malformation Reflex can be weak or exaggerated after breech birth

Additional newborn responses: yawn, stretch, burp, hiccup, sneeze Spontaneous behaviors Can be slightly depressed temporarily because of maternal analgesia or anesthesia, fetal hypoxia, or infection Parental guidance: most of these behaviors are pleasurable to parents Parents need to be assured that behaviors are normal Sneeze is usually response to lint, etc., in nose and not an indicator of a cold No treatment needed for hiccups; sucking may help
