THE NEWBORN ASSESSMENT

Apgar scoreExam•SKIN: Erythema toxicum, mongolian spots•HEENT: fontanelles•CARDIAC: PDA•ABD/GU: hypospadias, hydrocele•MS: hip dislocation•NEURO: babinski is normal

APGARS

Done at 1 min and 5 min (may be repeated at 5 minute intervals for infants with 5 min scores <7)Score 0 1 2

Heart Rate Absent <100 >100

Respiratory effort

Absent, irregular

Slow, crying Good

Muscle tone Limp Some flexion of extremities

Active motion

Reflex Irritability

No response

Grimace Cough or sneeze

Color Blue, pale Acrocyanosis

Completely pink

Erythema Toxicum neonatorum (the rash of the newborn)

COMMON skin condition in newborns, BENIGN Appears in 50% of newborns Usually between day 3 or life and 2 weeks of life Rash: small, yellow to white papules surrounded

by red skin, usually on face, chest, back, upper arms, sometimes on thighs.

Palms and soles are not involved No treatment needed. Usually fade and disappear over 2 weeks or more

Erythema Toxicum neonatorum

Acrocyanosis

Mongolian Spots

Benign Infantile Hemangioma

Common 3 stages: Growth, Stabilization, Disappearance Most common complication is ULCERATION Usually no treatment required and a simple BIH

resolves on its own.

Further evaluation needed for : Very large or segmented hemangiomas (>5cm) Multiple hemangiomas Located over sacral spine or at the midline Located near the eye Ulceration

Physical Exam of head, face, and neck

Asses head for its shape, symmetry, and fontanelles.

Caput succedaneum: It is subcutaneous and does cross suture linesCephalhematoma: It is subperiosteal and does not cross suture lines

Cephalohematomas, go away over the course of a few weeks.

Caput succadaneum, goes away in a few days

CARDIAC

Patent Ductus Arteriosus (PDA) Failure of the ductus arteriosus to close in the first

few days of life OR reopening after functional closure.

Up to 60% in preterm infants weighing < 1500 grams

Female to male ratio= 2:1 Systolic murmur that may be continuous, and is

heard best at the upper left sternal border. MANAGEMENT:

Indomethacin: a prostaglandin synthetase inhibitor, 80% CLOSURE RATE

SURGICAL closure.

The Abdomen

Palpate the kidneys.

Anus is visualized, but digital examination is not recommended unless obstruction is suspected. Meconium is usually passed in the first 12-24 hours. An absence of the passage of meconium by 24 hours may suggest either cystic fibrosis or Hirschsprung’s Disease.

imperforate anus

Inspect the glans for the location of the external urethral meatus. In Hypospadias, the meatus is located in an abnormal ventral position. The presence of Hypospadias in the newborn indicates a contra-indication for circumcision.

Genitals : Inspect the external genitalia for ambiguity

Genitals

Testes should be descended into the Scrotum or in the inguinal canals. You can ultrasound the area to “find them” if you cannot feel them.

Hydroceles or hernias are not uncommon in newborns.

After a breech delivery, the external genitalia are often erythematous and edematous.

Musculoskeletal The purpose of this examination is to detect gross abnormalities. The

appearance of the extremities at birth usually reflects the positioning of the child within the uterus.

Examine the hips for the possibility of dislocation. The presence of asymmetric skin folds on the medial aspect of the thigh, a positive galeazzi sign, and positive ortolani and barlow maneuvers are suggestive of a dislocated femur. There are risk factors associated with hip dysplasia, but one to remember is breech position. (ALL breech babies get an ultrasound of their hips done to rule out dysplasia)

Positive galeazzi sign

Ortolani Barlow

Babinski sign is normal in newborns (> 2 years of age is abnormal)

HypoglycemiaJaundiceHearing

NEWBORN ISSUES

Hypoglycemia-<40mg/dL

Differential Insufficient glucose delivery Decreased glycogen stores Increased circulating insulin (infant of a

diabetic mother, maternal drugs) Endocrine and Metabolic disorders Sepsis Hypothermia Polycythemia Asphyxia Shock

Hyperbilirubinemia

Total Serum Bilirubin Bilirubin peaks at age 5-6 days, then normally stabilizes and

drops. Low risk zone: do nothing Low intermediate risk: possibly supplement if breastfeeding, recheck in

24 hours. Encourage to put in sunlight. High intermediate risk zone: consider bili-blanket (photo therapy) or a

bili-light. Ensure not dehydrated. May need IV fluids. Physiologic jaundice: normal Breastfeeding jaundice: lack of breastmilk Breastmilk jaundice: persists in breastfed babies for 3 weeks to 4

months. Normal.

Remember Kernicterus Bilirubin >20-25 Can lead to permanent brain damage, even death.

Hearing

Routine hearing screening prior to discharge, using Auditory brainstem responses (ABR) Otoacoustic emissions (OAE) *If a child fails, further audiologic testing

needed.

Primitive ReflexesMilestones

Development

Galant Reflex

Developmental Milestones

Five Major Areas of Normal Development

1. Gross motor skills overall movements of large muscles e.g., sitting, walking, running

2. Fine motor/adaptive skills involve use of small muscles of the hands ability to manipulate small objects problem-solving skills eye-hand coordination

The schedule and also details about the conditions

Immunizations

If you memorize a typical schedule of immunizations at well child visits, you will probably have a hard time missing a vaccine question regarding timing of vaccinations.

FIRST A HINT

infected blood Can be asymptomatic Prodromal symptoms

Mild, pruritus, low-grade fever, malaise, sore throat (asymptomatic)

Erythema infectiosum-3 phases

Stage 1: facial erythema (slapped cheeks) Red papules coalesce forming fiery red, slightly edematous,

warm plaques that are symmetric on both cheeks and spare the nasolabial fold and circumoral region.

Fades in 4 days

Stage 2: Net pattern erythema Erythema in a fishnet-like pattern begins on the extremities 2

days after the facial erythema. Extends to the trunk and buttocks fading in 6-14 days

Stage 3: recurrent phase The eruption fades and then reappears in previously affected

sites on the face and body during the next 2-3 weeks. Triggers: emotional upsets, sunlight, temperature.
