Perinatal History, Mother’s History:
History of pregnancy, age, smoking, and substance abuse, nutrition, infection, previous pregnancies/outcome, hypertension/toxemia are all important to review.
Mothers with diabetes are prone to have
premature and large-for-gestational age infants.
Family history, delivery, and postnatal history will also provide
important information
Gestational Age
time since the estimated date of conception
Term Infant
born between 38 and 42 weeks of gestational age
Preterm Infant (premature)
less than 38 weeks of gestational age
Post term Infant weeks of gestational age
more than 42
AGA
Appropriate for gestational age
LGA
Large for gestational age. diabetes
SGA
Small for gestational age. mom on drugs
APGAR 1 minute score identifies
how well the infant tolerated delivery.
APGAR 5 minute score identifies
how successful our efforts were
APGAR Five factors are evaluated:
color, heart rate, reflex irritability, muscle tone and respiratory effort
APPEARANCE PULSE under 100 = 1 point GRIMACE - cough/sneeze = 2 points ACTIVITY - some flexion is 1 point RESPIRATORY EFFORT - slow weak cry = 1 point
APPEARANCE PULSE under 100 = 1 point GRIMACE - cough/sneeze = 2 points ACTIVITY - some flexion is 1 point RESPIRATORY EFFORT - slow weak cry = 1 point
0 to 3 points = resuscitate with 100% FiO2
4 to 6 points = stimulate
0 to 3 points = resuscitate with 100% FiO2
4 to 6 points = stimulate
Transillumination
Recommend when a pneumothorax is suspected
Transillumination
A bright fiberoptic light is placed against the infant’s chest in a darkened room
Transillumination
Normally a lighted halo is seen around the point of contact
Transillumination
A pneumothorax will cause the entire hemithorax to light up
Transillumination L. Diaphragmatic hernia there is
no light
Normal Temperature.
36.5 C.
Servo-controlled isolettes and radiant warmers provide
automatic adjustment of temperature
If the temperature probe comes off the skin or malfunctions the unit may
overheat causing high air temperature and the low skin temperature alarms to sound
When an infant is kept warm, the oxygen consumption is
reduced
Normal heart rate for a term infant is
110 - 160 beats/min. (preterm infants have faster rates)
Tachycardia
170 beats/min. or greater.
Bradycardia
less than 100 beats/min.
Pulse/Heart Rate. is Measured using
brachial, femoral, or apical pulse.
An infant can only increase his/her cardiac output by
increasing the heart rate.
Normal respiratory rate is
30 to 60 breaths/min. (higher in preterm babies).
Respiratory pause
apnea for 5- 10 sec, normal.
Short apnea
apnea for 10-20 sec, may be normal.
Long apnea:
apnea for more than 20 sec, always abnormal.
Blood Pressure Term infant:
60/40 mm Hg.
Blood Pressure Preterm infant:
50/30 mm Hg.
Birth Weight Term infant:
over 3000 g or 3 Kg
Birth Weight 28 week gestational age
1000 g.
Low birth weight infants are at higher risk for
respiratory problems.
9,000 - 30,000 normal WBC until
3 weeks old
Acrocyanosis is
bluish extremities and is not true cyanosis.
Check mucous membranes of the
mouth, tongue, and nail beds.
increased WOB for infant
retractions, nasal flaring and grunting.
Retractions
Intercostal, subcostal, substernal or supraclavicular retractions are signs of respiratory distress
Nasal Flaring
Dilation of nasal openings also indicates respiratory distress for infants who must breathe through their nose.
Grunting
A sound heard at the end of exhalation that indicates respiratory distress (RDS) from decreased lung volume.
Capillary Refill
Blanching the infant’s skin to see how long it takes for normal color to return.
Capillary Refill
Longer than 3 seconds may indicate a decreased cardiac output.
Silverman Score the higher the number is
the worse the baby is doing
Silverman Score is the Assessment of
respiratory distress.
Gestational Age
Dubowitz or Ballard Method
Dubowitz or Ballard Method Assessment of the gestational age is important to
differentiate between a premature infant and one that is just small for his/her gestational age.
Dubowitz or Ballard Method The higher the score
the higher the gestational age in weeks.
Dubowitz or Ballard Method
Normal score is 40 corresponding to 40 weeks.
Dubowitz or Ballard Method A score higher than 40 indicates
a post-term infant.
Dubowitz or Ballard Method
A score lower than 40 indicates a pre-term infant.
New Ballard Score (NBS) is a Modification of
Ballard Score.
New Ballard Score (NBS) Estimates
gestational age in very low birth weight infants.
PROM
premature rupture of the membrane. look for WBC going up and temperature would mean they have an infection
UA
umbilical artery = L. side
Pre- and Post-Ductal Blood Gas Studies, if right to left shunting occurs across the ductus arteriosus,
the PaO2 level obtained from a pre-ductal site (right arm) often exceeds the PaO2 level obtained from a post-ductal site (umbilical artery or a lower extremity vessel)
if the pre-ductal (right radial artery) PaO2 is 15 torr higher than the post-ductal (umbilical artery) PaO2 then
the patient has a patent ductus arteriosus with a right to left shunt
Pre- and Post-Ductal Blood Gas Studies
can also be evaluated by using transcutaneous monitoring or pulse oximetry.
Pre- and Post-Ductal Blood Gas Studies recommend an echocardiogram to
determine the cause of the shunt.
Blood Glucose term infants should have values
greater than 30 mg/dL. if lower then need to intervene
Blood Glucose Premature infants should have values
greater than 20 mg/dL. if lower then need to intervene
Lecithin/Sphingomyelin (L/S) ratio of 2:1 or higher is
good
Lecithin/Sphingomyelin (L/S) Ratio ratio less than 2:1 indicates
high risk of hyaline membrane disease (HMD) or infant Respiratory Distress Syndrome (IRDS)
As Lecithin/Sphingomyelin (L/S) Ratio drops below 2, incidence of HMD/IRDS ranges from 40-80%. Lower ratio indicating
higher risk.
As Lecithin/Sphingomyelin (L/S) Ratio drops below 2, incidence of HMD/IRDS ranges from 40-80%. Lower ratio indicating

As ratio drops below 2, Recommend
surfactant replacement therapy.

Pulmonary maturity even with diabetes.

Treating Severe Airway Obstruction in an Infant - If the infant is responsive
- Infant is straddled over the rescuer arm face down (prone), the head lower than the trunk, and the head is supported by firmly holding the jaw.
- Deliver 5 back blows with the heel of the hand between the infant’s shoulder blades.
- Turn the infant over and apply 5 chest thrusts (heimlich maneuver like on an adult)
- Repeat the sequence until the obstruction is relieved or the infant becomes unresponsive.
Treating Severe Airway Obstruction in an Infant - If the infant becomes unresponsive.
- Send someone to activate emergency response system.
- Place infant on a hard surface, begin CPR (no pulse check).
- Before attempting to ventilate, look for a foreign object in the mouth and remove it.
- Continue CPR for 5 cycles or about 2 minutes.
- if alone, activate EMS system.
- Return and continue CPR.
