45
Q

Subgaleal hemorrhage hematoma

A

Not a nl variant of birth and can lead to severe complications (anemia, resp. distress, seizures, shock death)
Occur when emissary veins rupture, leading to the accumulation of blood below the aponeurosis of the scalp and above the periosteum
Onset of swelling often occurs within 12-72 hours postpartum and will present as a fluctuate boggy mass over the scalp
Occasionally babies will develop raccoon eyes

46
Q

Eyes

A

Examine and ensure red reflex is present in both eyes

47
Q

Nose

49
Q

Ears

A

Examine ears for placement, mobility, and cartilage

50
Q

Automated Auditory Brainstem Response (AABR)

A

Measures how the acoustic nerve responds to sound. Clicks or tones are played through soft earphones into the baby’s ears. 3 electrodes placed on the baby’s head measure nerve response.

51
Q

Otoacoustic emissions (OAE)

A

Measures sound waves produced in the inner ear. A tiny probe is placed inside the ear canal. It measures the response (echo) when clicks or tones are played into the baby’s ears

52
Q

General mouth exam

A

Assess for any evidence of cleft palate, cleft lip or ankyloglossia
-Use a wooden tongue depressor and a pen light
-Examine the palate all the way to the uvula, which should be midline on exam
Newborn should have minimal salivation, gag reflex should be intact, as should the sucking and rooting reflexes, gums are pink and moist, rarely will a neonatal tooth be present at birth

53
Q

Ankyloglossia

A

The fancy medical term for tongue-tied

The frenulum tethers the tongue to the anterior floor of the mouth

54
Q

Comprehensive neck exam

A

Examine the neck by palpating the sternocleidomastoid muscles and rotating the head to either side to r/o congenital torticollis
Note any evidence of webbing of the neck
Examine the clavicles to ensure there is no evidence of clavicular fx from a traumatic delivery

55
Q

Torticollis

A

AKA Wry neck
A dystonic condition resulting most commonly from a shortened sternocleidomastoid muscle
Causes an asymmetric head and neck position
Refer to PT

56
Q

Characteristics of Turner syndrome

Low posterior hairline
Short stature
Heart-shaped face
Webbing of neck
Coarctation of aorta
Broad chest with widely spaced nipples
Cubitus valgus
Streak ovaries, amenorrhea, infertility
57
Q

Comprehensive chest exam

A

Watch to see that the chest rises and fall with inspiration and expiration

58
Q

Pectus carinatum

A

Pigeon chest

More prominent

59
Q

Pectus excavatum

A

Funnel chest

Looks scooped out

60
Q

What will occasionally be heard on cardiopulmonary exam?

A

Crackles

61
Q

Respiratory distress presentation

A

Cyanosis
Nostril flaring
Expiratory grunt
Any of these things warrant an additional work up

62
Q

Transient Tachypnea of the Newborn (TTNB)

A

MC reason of crackles
Defined by intermittent patterns of tachypnea, is most commonly seen in full term babies who are born via C-section
Believed to be linked to retained fluid in the lungs from gestation, this is often a condition that resolves with supportive care within 24-48 hrs

63
Q

How to do a cardiopulmonary exam

A

Listen on both the anterior and posterior thorax of the newborn to assess heart tones
-Murmurs that are transient and present at birth are typically benign
-Furthermore, congenital cardiac defects may not produce any murmur at time of birth
Next, feel both the brachial and femoral pulse of the infant. Absences of the femoral pulse, or evidence of a brachial-femoral delay is concerning for coarctation of the aorta and/or left sided heart defects

64
Q

What are relatively common in a newborn abdomen?

A

Diastasis recti and umbilical hernias

65
Q

Components of the umbilical cord

A

Comprised of 2 arteries and 1 vein, any deviation from this venous pattern would warrant immediate evaluation

66
Q

When will the umbilical cord typically dry up?

A

Within first 2 wks of life

67
Q

What should occur after inspection of the abdomen?

A

Auscultate the abdomen to ensure normoactive bowel sounds

68
Q

What does absence of bowel sounds indicate?

A

Obstruction, often resulting from meconium ileus

69
Q

Meconium

A

A dark green, tarry substance
The first feces to be passed by the newborn
Within first 24 hrs of life

70
Q

What can failure to pass meconium indicate?

A

Meconium ileus
Cystic fibrosis
Imperforate anus

71
Q

Where is the liver often palpable?

A

Approximately 2 cm below costal margin

72
Q

What can be palpated in the abdomen at birth?

A

Right kidney with deep palpation

73
Q

Female genital exam

A

Inspect the genitals noting that the labia majora is typically prominent
Nonpurulant d/c considered nl
Confirm the urethral meatus is located behind the clitoris by spreading the labia majora and using a pen light to examine the genitals

74
Q

What to look for in the scrotum

A

Typically large and should have 2 descended testicles present at time of birth
-Undescended has risk for testicular cancer
Scrotal swelling can be seen in the presence of hydrocele or hernia

75
Q

Foreskin info

A

The prepuce of the newborn male is often tight and cannot be retracted past the glans of the penis
-Don’t force retraction
Avg age of initial retraction is 10-11 yo

76
Q

Urination

A

Most newborns urinate within the first mins to hrs of life.

Newborns who have not urinated within the 24 hrs should be sent for additional workup such as renal u/s

77
Q

Musculoskeletal comprehensive exam

A

Assess all major joints and muscle groups on the newborn. Spontaneous bilateral movements of all extremities should be observed
Start by assessing the hands and palms for polydactyly, syndactyly or abnormal dermatoglyphic patterns, all of which can potentially indicate an underlying genetic disorder

78
Q

Congenital talipes equinovarus (CTEV)

A

AKA clubbed foot

79
Q

The Barlow maneuver

A

Performed by adducting the hip (bringing the thigh towards the midline) while applying light pressure on the knee, directing the force posteriorly. If the hip is dislocated the test is considered positive

80
Q

The Ortolani maneuver

A

Performed by flexing the hips and knees of a supine infant to 90 degrees, thenp lacing anterior pressure on the greater trochanters, while abducting the infant’s legs. A positive Ortolani sign is noted when the femoral head relocates anteriorly into the acetabulum, thus correcting for the Barlow maneuver

81
Q

Spinal exam

A

Check for any evidence of scoliosis, or abnl dimpling above the gluteal crease as this can be indicative of neural tube defects
Brace when angle is lower, surgery if angle is higher

82
Q

Neuro exam

A

Observe the posture of the infant
There should be flexion at the knees, hips and elbows
-Infants with hypotonia often assume a frog leg position
Next assess level of alertness
-Lightly touch the cheek or foot of the baby to see that they are easily arousable
Also assess reflexes
