The Newborn
Care Management: From Birth Through The First 2 Hours
Apgar Score
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.
TABLE 7-1
Sign | SCORE | ||
0 | 1 | 2 | |
Heart rate | Absent | Slow (<100 beats/min) | >100 beats/min |
Respiratory effort | Absent | Slow, weak cry | Good cry |
Muscle tone | Flaccid | Some flexion of extremities | Well flexed |
Reflex irritability | No response | Grimace | Cry |
Color | Blue, pale | Body pink, extremities blue | Completely pink |
Initial Physical Assessment
The initial physical assessment includes a brief review of systems:
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 |
∗All durations for persistence of reflexes are based on time elapsed after 40 wk of gestation; that is, if this newborn was born at 36 wk of gestation, add 1 mo to all time limits given.
