I read with interest the article on ‘Guidelines
2000 for Neonatal Resuscita-tion’(1) which was based on ‘International
Guidelines for Neonatal Resuscitation’(2). On 27th October 2000, the
American Academy of Pediatrics formally launched Neonatal Resuscitation
Programme (NRP) Provider Course and released a new ‘Textbook of
Neonatal Resuscitation, 4th Edition’ along with multimedia CD-Rom(3).
All of us, who are involved in the care of newborn
are curious to know the changes which will have a bearing on our
practice of newborn resuscitation. Given below are the important changes
in the revised NRP in a tabular form (Table I) to serve as a
ready reckoner.

Preparation
-
At every
delivery there should be at least one person with the skills
required to perform a complete resuscitation. When that
person is caring for the mother, another person capable of
initiating and assisting with resuscitation must be
primarily responsible for the infant, even when a normal,
healthy infant is expected.
Assessment
After completing
initial steps baby is assessed for respirations, heart rate and
color.
Initial steps
-
Dry, remove
wet linen, position, suction, stimulate to breathe, if
necessary.
-
Then assess
respirations and intervene, if necessary.
-
Then assess
heart rate and intervene, if necessary.
-
Then assess
color and intervene, if necessary.
Assessment is
done in the sequential manner for respirations, heart rate and
color
-
In situations
of meconium stained liquor for oropharyngeal suction use 10 F or
larger suction catheter.
-
Tracheal
suctioning is indicated for all infants who are depressed and
have meconium and for any infant passing through thick
particulate meconium stained liquor.
-
Tracheal
suction should be repeated till returns are clear. If the baby
is severely depressed positive pressure ventilation may be
needed even if some meconium remains in the airway.
Chest Compression
-
Chest
compressions are indicated when the heart rate, after 15-30
seconds of positive pressure ventilation with 100% oxygen, is
below 60 bpm or between 60 and 80 bpm and not increasing.
-
Chest
compressions are stopped if the heart rate >80/bpm
-
Lower third of
the sternum is located by imagining a line drawn between the
nipples.
-
During chest
compressions, depress the sternum ½ to ¾ inch.
Medications
-
Epinephrine is
indicated when the heart rate remains below 80 bpm despite a
minimum of 30 seconds of adequate ventilation with 100% oxygen
and chest compression or if the heart is zero.
-
Outlines
general instructions for epinephrine administration via
endotracheal tube.
-
Volume
expanders include 5% albumin.

At every
delivery, there should be at least one person whose primary
responsibility is the baby and who is capable of initiating
resucitation. Either that person or someone else who is
immediately available (not at home or in a remote hospital
location) should have the skills required to perform a
complete resuscitation, including endotracheal intubation
and administration of medications.
Assessment of the newborn begins
at the time of birth. The five questions clearly differentiate
the baby in need of assistance from the baby who can receive
routine care. If the answer to any of these initial assessment
questions is no, the baby requires the initial steps under the
radiant warmer. If all answer are yes, the baby can be
provided routine care:
1. Is the
amniotic fluid clear of meconium?
2. Is the baby
breathing or crying?
3. It there
good muscle tone?
4. Is the baby’s
color pink?
5. Is the baby
term?
-
Nearly 90% of
newborns are vigorous term babies with no risk factors and clear
amniotic fluid. They can be directly placed on mother’s chest,
dried and covered with dry linen. Warmth is maintained by direct
skin-to-skin contact with the mother. Clearing of the upper
airway can be provided as necessary by wiping the baby’s mouth
and nose. Ongoing observation of breathing, activity and color
should be carried out.
Initial steps:
If deemed necessary:
-
Position,
clear airway, dry, remove wet linen, stimulate, reposition,
give oxygen as necessary.
-
Simultaneously, evaluate respirations, heart rate color during
the initial steps.
-
If the baby
is breathing and cyanotic or begins to breathe during the
initial steps and is cyanotic, administer free-flow oxygen.
After completion of the initial steps, base further
interventions on simultaneous assessment of respirations,
heart rate and color.
Assessment is
done simultaneously for respirations, heart rate and color
-
For oro-pharyngeal
suction use 12 F or larger suction catheter.
-
The need to
suction the trachea for meconium is determined by whether or not
the baby is vigorous at birth. Vigor is defined by strong
respiratory effort as evidenced by cry, good muscle tone, and a
heart rate >100 bpm. If any of the criteria is not met, the
newborn requires tracheal suctioning. Thin or thick meconium
does not guide need for intubation.
-
If you recover
meconium with the first suction, check the heart rate. If the
baby does not have significant bradycardia, reintubate and
suction again. If the heart is low you may decide to administer
positive pressure ventilation without repeating the procedure.
-
Chest
compressions are indicated when the heart rate remains at <60
bpm despite 30 seconds of effective positive-pressure
ventilation.
-
Chest
compressions are stopped if the heart rate >60/bpm.
-
Lower third of
the sternum is located by running finger along the lower edge of
ribs till xiphoid. Area just above xiphoid is used for chest
compression.
-
Depress the
sternum one-third of the anterior-posterior diameter of the
chest.
-
Epinephrine is
indicated when the heart rate remains below 60 bpm despite 30
seconds of assisted ventilation and another 30 seconds of
coordinated chest compressions and ventilation.
-
Outlines
detailed instructions for epinephrine administration via
emergency umbilical venous catheter as well.
-
5% albumin has
been deleted from the list of volume expanders.
-
Indication for
naloxone hydrochloride.
Severe
respiratory depression and a history of maternal narcotic
administration within the past 4 hours after 30 seconds of
positive-pressure ventilation has restored normal heart rate and
color.
-
A medication
administration performance checklist evaluates the learner’s
ability to administer epinephrine via endotracheal tube and to
assist with placement of or place an emergency umbilical venous
catheter and administer volume expander and/or medication.
-
Lesson 7
includes information on:
-
Speical
situations that may complicate resuscitation and cause ongoing
problems.
-
Subsequent
management of the baby who has required resuscitation.
-
How NRP
principles apply to babies beyond the immediate newborn period
or outside the hospital delivery room?
- Ethical considerations about
starting, non-initiation and stopping resuscitation.
