This document provides an overview of neonatal resuscitation. It defines neonatal resuscitation as interventions at birth to support breathing and circulation. It discusses the history of neonatal resuscitation and how techniques have developed over time. It also outlines the key steps and principles of resuscitation including initial assessment, positive pressure ventilation, chest compressions, and intubation. Special considerations for preterm infants are also addressed.

3. Definition
• Neonatal resuscitation is a set of interventions at the time of birth to
support the establishment of breathing and circulation. (AAP)
Levels.
Simple interventions – drying and stimulation, suction with bulb
syringe.
Basic resuscitation – PPV (bag and mask), deep suction.
Advanced resuscitation – chest compressions, Endotracheal
Tube(ETT), medications and fluids.
4. Historical aspects.
• For the past 45years,fetal anoxia was one of the most investigated
conditions affecting the new born.
• It was then realised that obstruction to the airway immediately
following birth should be the first concern in newborn resuscitation.
• 18th century Scottish obstetrician Blundell first used mechanical
device for tracheal intubation in living newborn.
5. • In 1920, Joseph B. DeLee introduced simple rubber catheter and glass
trap to clear upper airways and stomach.
• In 1953 Apgar score was given by Varginia Apgar. She is also the first
to catheterise Umbilical Artery in new born.

6. • In 1966 national guidelines for resuscitation of adults was
recommended by National Academy of Science.
• In 2000 the consensus document on advanced life support of the new
born converted the previously published advisory statements into a
set of guidelines.
• These guideline were revised further in 2010, 2015 and latest revision
being in 2020 and published in June 2021 (8th edition of the Neonatal
Resuscitation Program) by AAP and AHA.
7. Statistics
• Globally, 2 to 10 per 1000 term newborns faced perinatal asphyxia
(inability of a newborn to initiate and sustain adequate respiration
after delivery) , and the report of WHO 2014 indicated that birth
asphyxia leads to about 4million neonatal deaths annually.
• The incidence of birth asphyxia in most developed countries accounts
for less than 1/1000 of newborn deaths contrary to developing
countries where it ranges from 4.6/1000 to 26/1000 live births.
8. • More than 25.0% of the world’s newborn deaths have occurred in
Africa, of which birth asphyxia accounts for 24.0%.
• From 20 countries in the world with the highest risk of neonatal
death, 75.0% are in Africa. (Guo A et al 2017)
• The incidence of asphyxia in East, Central and southern Africa was
22.0% by 1993. (kinoti S- asphyxia of the new born in east, central
and southern Africa)
But by 2020, prevalence of perinatal asphyxia was at 18.0% and 9.0% in
East and Central African countries respectively (Yinager Workineh et al,
prevalence of perinatal asphyxia in East and Central Africa)
9. Why learn newborn resuscitation?
• Uganda’s neonatal mortality rate (NMR) is 19 deaths per
1,000 live births with 30 deaths per 1,000 live births in rural
areas and 31 deaths per 1,000live births in urban areas.
(UNICEF facts sheet 2021)
With birth asphyxia as the leading cause.

11. Overview and principles
• Approximately 90% of newborns make smooth transition from
intrauterine to extrauterine life requiring little or no assistance
• 10% of newborns need some assistance
• Only 1% require extensive resuscitation
• We must always be prepared to resuscitate, as even some of those
with no risk factors will require resuscitation.
12. Fetal transition.
Before birth
• Oxygen supply by placental membranes
• No role of lungs- fluid filled alveoli and constricted arterioles due to
low O2 on Fetal blood.
• Thus the increased pulmonary resistance leads to shunting of blood
from pulmonary artery to ductus arteriosus to aorta.
13. After birth
• Baby cries - Takes first breath - Air enters alveoli - Alveolar fluid gets
absorbed -Increased P02 relaxes pulmonary arterioles - Thus
decreased PVR ( pulmonary Vascular Resistance).
• Umbilical arteries constrict and clamp cord- closure of umbilical
arteries and umbilical vein- increased SVR (Systemic Vascular
Resistance)
• Decreased PVR and increased SVR – functional closure of ductus
arteriosus- increased blood flow into lungs – oxygenation – supply to
body through aorta.
14.
15. Signs of compromised new born
These present as a consequence of interruption in transition.
Low muscle tone
Respiratory depression (apnoea/gasping )
Tachypnea
bradycardia
Hypotension
Cyanosis
Low oxygen saturation
16. Principles
• The sequence of resuscitation in adults is C-A-B
• But in newborns it remains A-B-C as the etiology of neonatal
compromise is nearly always a breathing difficulty.
• A- position and clear
• B- stimulate breathe
• C- assess HR and oxygenation
• D-drugs
17. Preparing for birth
• Review antepartum and intrapartum risk factors.
• Must know – expected gestational age? – is the amniotic fluid clear? – number of babies
expected? – any additional rick factors?
• Personnel – at least 2.
• Equipment
Resuscitation table
Sterile linen
Suction apparatus
Laryngoscope
Ambu bag and face mask
Oral airways
Oxygen with flow meter and tubing
Endotracheal tubes
Sterile gloves
21. What to do with a vigorous term newborn
• Provide warmth – 36.5 – 37.5c
place baby under radiant warmer uncovered.
• Position the head and neck
neck in neutral position, head in sniffing position.
• Clear secretions, if needed
bulb syringe or penguin sucker.
• Dry
• Stimulate
22. Re-evaluation
• Respiration – rate 40 to 60b/m
• Heart rate – auscultation or pulsations at the base of cord is felt. 6s *
10. > 100b/m
• Oxygenation by oximeter
23. Airway
• Reposition neck and head
• Suction (suction catheter with/without laryngoscope guided).
• Laryngeal mask airway.
24. • If breathing and heart rate is over 100b/m, but baby is still cyanotic:
Acrocyanosis – bluish hue of hands and feet
Central cyanosis – bluish hue of lips, tongue and torso
Place pulse ox and provide supplemental oxygen by
-flow-inflating bag and mask
-Oxygen tubing
-t-piece resuscitator
-self inflating bag
If cyanosis persists, provide positive pressure ventilation (PPV)

29. POSTIVE PRESSURE VENTILATION
Indication
• Apnoea
• Gasping
• HR <100b/m
• O2 saturation below the target range despite free-flow oxygen or
CPAP.
Effective ventilation is the single most important step in CPR of
compromised infant.
30. Equipment for PPV
• Masks
Rims
-cushioned , non cushioned
Shape
-round, anatomically shaped
Size
-small, large
Notably, mask should cover the tip of the chin, mouth and nose so as to
create a seal.
31. • Devices

33. • Peak Inspiratory Pressure (PIP)
The summation of the pressure generated by the ventilator to overcome airway
resistance and alveolar resistance to attain peak inspiratory flow and to deliver
desired tidal volume.
• Positive End Expiratory Pressure (PEEP)
Is the pressure applied by the ventilator at the end of each breath to ensure
that the alveoli are not so prone to collapse.
Reduces trauma to the alveoli, increases functional residual capacity which
improves oxygenation, lesser pressure is needed to get the same volume of air
into the lung as the alveoli are already open thus increasing compliance,
ventilation/perfusion mismatches are improved.
34. CPAP
• Its the pressure in the system at the end of spontaneous breath when
a mask is held tightly on baby’s face but the bag isn’t being squeezed.
NCPAP.
35. Starting ventilation
Before beginning positive pressure ventilation:
• Select appropriate-sized mask
• Be sure airway is clear
• Position baby’s head
• Position yourself at baby’s head or side
• Confirm equipment is attached to oxygen source.
36. Continued…
• How much oxygen
• >35weeks of gestation begin with 21%
• <35weeks begin with 21-30%
• Breaths should be given at 40 to 60 bpm
• How much pressure?
• Neopuff/neotee
• PIP at 20-25cm H20
• PEEP at 5cm H2O.
37.
38. Signs of effective ventilation
• Signs of adequate ventilation
Improved heart rate, color and muscle tone.
• Signs of improvement in the newborn
Improved heart rate, color, breathing, tone and saturation.
Thus these parameters are reassessed during PPV.
39. After starting PPV
• At 15seconds, and 30seconds from the start of PPV, the assistant
should announce loudly;
1. Change in Heart rate (increasing, decreasing or the same)
2. chest movements (is moving or not moving)
3. +/- o2 saturation.
40. First assessment (after 15 seconds)
• After 15seconds of PPV
• Announce heart is
increasing
• Continue PPV
• Second HR
assessment after
15seconds of PPV
• Announce heart
rate not increasing,
chest moving.
• Continue PPV that
moves the chest
• Second HR
assessment after
another 15secs of
PPV that moves the
chest.
• Announce HR not increasing, chest is
not moving
• Ventilation corrective steps until chest
movements with PPV.
• Intubate or laryngeal mask if necessary
• Announce when chest is moving
• Continue PPV that moves the chest
• Second HR assessment after 30seconds
of PPV that moves the chest.
Increasing Not increasing chest moving Not increasing Chest not moving.
41. Second assessment (after 30 seconds)
• After 30seconds of PPV that moves the chest
• Continue PPV 40-60
breaths/min until
spontaneous effort
• Reassess ventilation
• Ventilation
corrective steps if
necessary.
• Reassess ventilation
• Ventilation corrective steps if necessary
• Insert an alternative airway
• If no improvement 100% oxygen and
chest compressions.
At least
100bpm

42. Causes and solutions for inadequate chest
expansions.
Condition Actions
Inadequate seal Reapply mask to face and lift jaw forward
Blocked airway Reposition the head
Check for secretions : suction if present.
Ventilate with the newborn’s mouth slightly open.
Not enough pressure Increase pressure until there is a perceptible chest
movement.
Consider endotracheal intubation.
43. Mr. SOPA
CORRECTIVE STEPS Actions
M Mask adjustment Reapply the mask, consider the 2 hand technique
R Reposition airway Place head neutral or slightly extended
Try PPV and reassess chest movements
S Suction mouth and nose Use a bulb syringe or suction catheter.
O Open mouth Open the mouth and lift the jaw forward.
Try PPV and reassess chest movements
P Pressure increase Increase pressure in 5 to 10cm H2O increments, maximum 40cm
H2O.
Try PPV and reassess chest movements
A Alternative airway Place an endotracheal tube or laryngeal mask.
Try PPV and assess chest movements and breath sounds
44. Orogastric tube
• After several minutes of PPV or CPAP with a mask, gas enters the
stomach and may interfere with ventilation or cause regurgitation and
aspiration.
• Place orogastric tube, suction gastric contents and leave it uncapped
to act as a vent to the stomach.
45. Chest compressions.
• Indicated when heart rate remains less than 60bpm despite
30seconds of effective PPV.
• Need 2 people.
• Ratio of 3:1 compression to ventilation ratio. (30breaths and
90compressions in one minute)
• Place thumbs or fingers 2cm below the imaginary nipple line.
• Apply pressure on the sternum during compressions, compressions
depth is approximately one-third of the anterior posterior diameter of
the chest.
• Allow chest recoil and ventilation.
49. Reassessment.
Check HR after 60seconds.
If >60bpm, stop compressions but continue ventilation at 40 to
60bpm
If <60 check quality of ventilation and compressions
If still remains less than 60bpm, consider intubation if not already
done, consider epinephrine either via ETT or insert umbilical
catheter.
51. Endotracheal intubation
Indications
To improve ventilation after several minutes ineffective bag-and-mask
ventilation
To facilitate coordination of chest compressions and ventilation
To administer epinephrine while establishing IV access.
Special
Extreme prematurity
Surfactant administration
Suspected diaphragmatic hernia.
HR <100b/m in spite of PPV.
HR <60b/m
Baby is floppy, not crying and preterm.
52. Equipment.
• Laryngoscope blade
• 00 for extreme prematures
• 0 for preterm newborns
• 1 for term newborns
• Laryngoscope, check blade, handle and functioning light.
• Suction source, set at 80-100mm Hg, large suction catheter for
mouth/pharynx, small catheter for endotracheal tube (5 or 6 F).

55. Steps for intubation
1. Preparation for insertion
stabilize the newborn’s head in the sniffing position.
deliver free-flow oxygen during the procedure.
2. Insertion of laryngoscope
slide the laryngoscope over right side of the tongue, pushing the
tongue to the left side of the mouth.
advance blade until the tip lies just beyond the base of the tongue.
3. Lift blade
lift the blade slightly on angle to ceiling, raising the entire blade not
just the tip.
Visualize pharyngeal area. Don’t rock.
56. 4. Visualize landmarks
Vocal cords should appear as vertical stripes on each side of the
glottis or as an inverted letter V.
apply downward pressure on cricoid to help bring glottis into
view. Suction for visualization, if necessary.
5. Inserting tube
insert the tube following the curvature of the blade. Insert the
tip of the endotracheal tube until the level of the vocal cords.
Limit attempts to 30 seconds, and if the cords are closed, wait for them
to open.

60. Confirmation of ETT placement.
• Detecting exhaled CO2 and rapid rise in heart rate are primary
methods.
• Auscultate breath sounds during PPV, near both axillae.
• Symmetrical chest movements.
• Little or no air leak from mouth during PPV.
• Decreased or absent air entry over the stomach
• Chest X-ray.
63. If baby’s condition worsen after intubation

D Displaced endotracheal tube
O Obstructed endotracheal tube
P Pneumothorax, collapsed lung
E Equipment failure.
64. CPAP in the delivery room
• Importance
• CPAP if initiated early at the time of delivery, established adequate
lung volume or functional residual capacity
• It avoids the need for intubation
• Reduces need for surfactant.
• Ventilation also leads to volutrauma and lung inflammation.
• It also prevents the injuries caused by mechanical ventilation which is
more aggressive.
65. Indications for CPAP.
Preterm neonates Term neonates
Respiratory distress in the delivery room Moderate to severe respiratory distress
Atelectasis Meconium aspiration syndrome
Recurrent apnoea Large patent ductus arteriosus
Pulmonary edema Neonatal pneumonia

69. DRUGS.
Epinephrine
• Indicated when heart rate remains <60b/m.
• Not indicated before adequate ventilation is established
• IV or endotracheal route,
• 0.1 to 0.3ml/kg of 1:10,000 solution (0.3 to 1 ml/kg if given
endotracheal)
• As rapidly as possible.
• Reassess after 1 minute, if HR <60bpm repeat dose every 3 – 5
minutes. And consider increasing dose to higher end of range.
70. Volume expanders
• If no response to epinephrine especially with persistent bradycardia
and shock is suspected like in placenta Previa/abruption.
Normal saline is recommended but ringer’s lactate, or O Rh negative
blood can be used.
10ml/kg via umbilical vein given over 5 to 10minutes.
71. Resuscitation of preterms
• Thermoregulation:
Increase delivery room temperature
Radiant warmer
Polyethylene plastic bag or wrap
Preheated transport incubator
Monitor baby’s temperature frequently.
• Respiratory support
Use oxygen blender, adjust oxygen concentration to target 85% - 95%.
Use lower PIP 20-25cm of H20 during PPV
Consider giving CPAP and/0r surfactant.
72. Post resuscitation care.
• Monitor the baby’s temperature
• Monitor blood glucose
• Monitor the baby for apnoea and bradycardia.
• Proper transport for admission including warm transport and
maintained respiratory support.
Discontinuation of resuscitation efforts may be appropriate after 10
minutes of absent heart rate following complete and adequate
resuscitation efforts.
73. Warm transport
• The incidence of hypothermia at time of admission to the NICU in VLBW
newborns ranges from 31% to 78% (Watkinson Met al 20006 and
zymankiewicz M et al 2003)
• A study in Nsambya Hospital reported 87% of all preterms had
hypothermia at the time f admission to newborn unit (Cheptoris and
Nakibuuka et al 2016).
• each 1c decrease in axillary temperature is associated with a 28-75%
increase in neonatal mortality (abbot and Mullany LC et al 2010)
Newborns loss heat through radiation, convection, evaporation and
conduction.

Psalms 127: 1-2
Unless the Lord builds the house, its builders labour in vain.
Unless the LORD watches over the city, the watchmen stand guard in vain.
In vain you rise early and stay up late, toiling for food to eat – for he grants sleep to
those he loves.
