RSPT 2353 – Neonatal/Pediatric Cardiopulmonary Care

Assessment of the Neonatal & Pediatric Patient

Lecture Notes

Reference & Reading: Whitaker, Ch 4 & 5

I.

Assessment of the neonate begins when the baby transitions from uterine life to survival outside the uterus. Assessment skills must be keen in determining how the patient is adapting to its new environment. There are several systems in place to gauge how well the baby is transitioning

II.

Assessment begins with: Obstetric, pregnancy and L&D history

III.

Assessment in Labor & Delivery (pg. 100) - Immediately after delivery

APGAR scores will be assigned

 Objectively evaluates the condition of a neonate

 Areas examines are: HR, respiratory effort, muscle tone, reflex irritability and color

 Each area gets a score of 0, 1, or 2; assessed at 1 and 5 minutes and if necessary then every 5 minutes up to 20 minutes

Assessing Gestational Age a.

Dubowitz: Several criteria when examined determine gestational age

 Accurate within first 2 weeks of life, consistent results in first 5 days

 Uses 11 physical signs and 10 neurologic signs

 Each sign is assigned a score from 1 to 5

 The score will add up to gestational age b.

Ballard:

 Modified the Dubowitz to shorten time for assessment

 Looks at 6 physical and neurologic signs

 Can assess from 22 to 44 weeks, between 30 and 42 hours of life c.

Using physical exam to determine gestational age

 Very quick , easily and relatively reliable, especially during resuscitation

 Can be determined in < 1minute if skilled

M

ATURITY a.

25 -26 weeks or less skin is very gelatinous , transparent, & vessels are clearly seen b.

As gestation advances, skin is more pink and vessels are less visible c.

Term neonates will have adult like skin, vessels not visible d.

Post-term neonates, skin will be very wrinkled and sometimes peeling

Lanugo

a.

Fine, downy hair covers fetal body b.

Appears around 26 weeks and covers thorax, head and extremities c.

At 28 weeks it begins to thin d.

It should begin to disappear at 32 weeks

ECOIL a.

25 – 26 weeks or less will have flat pinna b.

Cartilage is not present until 34 weeks

T

ISSUE a.

25 to 26 weeks or less – not recognizable b.

27 weeks – red circle; no tissue c.

Week 30 – breast bud present

G

ENITALIA a.

25 to 26 weeks or less; Male - scrotum not recognizable, testes have not descended; Female – labia minora & clitoris protrude

S OLE C REASES a.

26 weeks – faint red lines b.

30 weeks – anterior portion of foot c.

34 weeks – 2/3 of the sole d.

Term – covered

E YES

– The baby is considered extremely premature if the eyes remain fused.

V.

Classifying the Neonate – based on weight and exam using a intrauterine growth chart

 AGA – appropriate for gestational age

 LGA – large for gestational age

 SGA – small for gestational age

 IUGR – Intrauterine growth retardation

VI.

Examining the Neonate a.

Quiet Exam

 Color

 Muscle tone

 RR – normal 30-60 bpm; tachypnea >60 bpm

 Signs that a patient is in respiratory distress

1.

Nasal flaring

2.

Grunting

3.

Retractions

 Silverman score can gauge how much distress a patient is in

1.

Scores 0 – 10

2.

High score = distress, low score = none or less distress b.

Physical Exam

 Presence of clefts

 Chest exam – tactile fremitus

 Normal HR 120 – 160bpm ; <100bpm bradycardia

 Pulses – abnormal femoral pulses = indication of CHD

 BP – see table 5-1;

1.

Mean Blood Pressure

2.

MBP = Gestational age + 5

 Abdomen – scaphoid abdomen, enlarged abd

VII.

Examining the Pediatric Patient a.

History b.

RR – evaluating respiratory distress

 >1 year: > 40 bpm

 > 5 years > 35 bpm

 Nasal flaring still possible

 Head-bobbing c.

HR & BP is dependent on age or baseline d.

ABGs should be normal or baseline
