4. Foundations of neonatal Resuscitation
• After birth, the baby's lungs must take over respiratory function.
• They must be filled with air to exchange oxygen and C0 2
• Respiratory failure can occur if the baby does not initiate or cannot maintain
effective breathing effort.
• If respiratory failure occurs either before or after birth, the primary problem is a
lack of gas exchange.
• Therefore, the focus of neonatal resuscitation is effective ventilation of the
baby's lungs
Ventilation of the newborn's lungs is the single most important and effective
step in neonatal resuscitation.
7. Anticipating and preparing
for Resuscitation
Don’t forget to prepare also
emergency DRUGS (Epinephrine,
fluid for expansion,… )
8. Anticipating and preparing for Resuscitation
Pre-resuscitation team briefing
• Assess risk factors.
• ldentify team leader.
• Anticipate potential complications and plan a team response.
• Delegate tasks.
• ldentify who will document events as they occur.
• Determine what supplies and equipment will be needed.
• ldentify how to call for additional help

12. The neonate or infant senses heat loss as a stress and responds with increased heat production and peripheral
vasoconstriction, with centralization of circulation, in an effort to maintain the core temperature
Mechanisms of heat loss
Step 1: PROVIDE WARM
30sec
Initial steps
first 30sec
13. Hypothermia:
occurs when, Heat losses exceed heat production, dropping the infant’s
temperature below the normal range of 36.5° to 37.5°C (97.7° to 99.5°F)
Hyperthermia: increase in the body temperature to above 37.5°C (99.5°F)
Mild hypothermia (cold stress): 36° to 36.4°C (96.8° to 97.5°F)
Moderate hypothermia: 32° to 35.9°C (89.6° to 96.6°F)
Severe hypothermia: Below 32°C (89.6°F)
Step 1: PROVIDE WARM
30sec
Initial steps
first 30sec
14. Effects of hypothermia
• Peripheral vasoconstriction (Acrocyanosis, pallor, and coldness to touch)
• Respiratory distress / apnea (a strong pulmonary vasoconstrictor inducing hypoxemia and central cyanosis)
• With Hypoxia, shift to anaerobic metabolism and lactic acid production
• Plus Increased oxygen consumption and metabolic demands result in metabolic acidosis
• May even lead to arrhythmias (Bradycardia and death)
• Depletion of caloric reserves and hypoglycemia,…
However : Controlled hypothermia has a neuroprotective effect in term and near-term infants with
moderate to severe hypoxic ischemic encephalopathy
Step 1: PROVIDE WARM

15. Prevention of heat loss in the delivery room
• Warm environment, room temperature >25°C: Maintains temperature and reduces insensible water loss
(IWL) by 25%
• Radiant warmer
• Dry the skin with a prewarmed towel and then remove any wet towels immediately
• Hats : Stockinette caps ?, Woolen hats ,…
• The Neonatal Resuscitation Program and the International Liaison Committee on Resuscitation consensus
statement recommends the use of a plastic wrap in addition to standard techniques in the delivery room
for very–low-birth-weight infants
Step 1: PROVIDE WARM

Initial steps
first 30sec
16. Occlusive plastic blankets/bags
Extremely low–birth-weight preterm newborn
wrapped in occlusive polyethylene sheet
during resuscitation.
Polyethylene bags (20 cm × 50 cm)
prevent evaporative heat loss in infants <29 weeks’ GA
Environment: Maintains temperature and reduces insensible water loss (IWL) by 25% (24,25)
Access: Allows neonatal resuscitation (secure airway, intubation, and chest compressions), but vascular access is limited
Asepsis: Limited by access
Precautions: Record core temperature every 5 to 10 minutes until infant is stable
Complications: Hyperthermia, skin maceration, risk of infection
17. Radiant warmer bed: For unstable infants
Precautions:
Keep infant 80 to 90 cm from radiant heat
For premature infants, heat shielding must be added. Increase fluid infusions
To avoid burns, do not place oily substances on infant’s skin.
• Unimpeded access to infants receiving intensive care
• Ability to maintain infant position and wide sterile field;
• also allows assistants to participate
• Leave the baby uncovered to allow full visualization and to permit the
radiant heat to reach the baby.
Complications:
Hyperthermia, Dehydration, Burns, …
Unstable
18. Mechanisms of heat loss/gain in infants
during delivery room resuscitation and stabilization:
(A)
Conventional:
drying and placement under
Radiant warmer
(B)
Radiant warmer PLUS Vinyl bag.
(C) Radiant warmer PLUS
Thermal mattress
19. Resource-Limited Settings :
WHO Standard recommends measures to prevent hypothermia.
• Warm delivery rooms
• Immediate drying
• Skin-to-skin contact
• early breast-feeding
• Postponed bathing and weighing, appropriate clothing and bedding,
and warm transportation and resuscitation
• Kangaroo mother care (KMC)
20. Step 2: DRY
30sec
Initial steps
first 30sec
• Gently rub the back, trunk, or extremities
• No Overly vigorous stimulation, can cause injury.
• Never shake a baby
• Gently dry with dry towels or blankets
• If towel or blanket becomes wet, discard and use fresh
For extreme preterm < 32w GA :
should be covered immediately in polyethylene plastic if available and skip
drying by towels or blankets
Step 3: STIMULATE
21. Step 4: POSITION THE HEAD AND NECK TO OPEN AIRWAY
30sec
Initial steps
first 30sec
• Position the baby on the back (supine)
• Head and neck neutral or slightly extended «sniffing the morning air" position
22. Step 5: SUCTION, IF NEEDED
30sec
Initial steps
first 30sec
Suck oropharynx under direct vision
Do not do deep, blind suction (before first breath and drying/stimulating)
When ?
Routine suction for a crying, vigorous baby is not
indicated
Clear secretions from the airway only if :
• if the baby is not breathing
• if the baby is gasping
• if the baby has poor tone
• if secretions are obstructing the airway
• if the baby is having difficulty clearing their
secretions
• or if you anticípate starting PPV.
How?
Suctioning gently with a bulb syringe upper airway
«Mouth before Nose"
How to Remember :
“M" comes before ”N" in the alphabet
Unnecessary suction
can be harmful.
Suction only if secretions
block mouth and nose
and you cannot ventilate
(WHO)
23. Routine care of newborn
• Provide warmth,
• Dry
• Stimulate.
• Position the head and neck.
• Clear secretions if needed

If severe blood
loss and/or anemia is
suspected or documented
• Administration of a volume expander is indicated
if the baby is not responding to the steps of
resuscitation and there are signs of shock or a
history of acute blood loss.
• Volume expanders should not be given routinely
during resuscitation in the absence of shock or a
history of acute blood loss.
54. Pass NG tube or Orogastric tube
if Prolonged PPV or need of continuous CPAP
If you continue face-mask PPV or continuous positive airway pressure (CPAP)
for more than several minutes, an orogastric tube should be inserted to act as
a vent for gas in the stomach.
55. What do you do if the baby is not improving after giving
intravenous epinephrine and volume expander?
1. Is the chest moving with each breath?
2. Is the airway secured with an endotracheal tube oral laryngeal mask?
3. Are 3 compressions coordinated with 1 ventilation being delivered every 2 seconds?
4. Is the depth of compressions one-third of the AP diameter of the chest?
5. Is 100% oxygen being administered through the PPV device?
6. Was the correct dose of epinephrine given intravenously?
7. Is the umbilical venous catheter or intraosseous needle in place or has it been dislodged?
8. Is a pneumothorax present?
56. When to stop resuscitation ?
Positive response
• HR > 100*
• Spontanuous respirations*
• Fair muscle tone
• Appropriate target SpO2 (if not, can requires to continous O2 supplementation,
CPAP, … )
Negative response
HR < 30 or Undetectable
No signal pulse oxymeter
+No spontanous respiration
+No muscules tone, pallor

Post resuscitation care
57. When to stop resuscitation ?
In high resources Setting, at the THERAPEUTIC HYPOTHERMIA ERA
• Previous editions of the AHA Textbook of Neonatal Resuscitation suggested that it may be reasonable
to stop resuscitative efforts if the heart rate was undetectable after 10 minutes of resuscitation.
• The 2020 edition AHA Textbook of Neonatal Resuscitation suggests that the time interval to consider
stopping resuscitative efforts should be around 20 minutes:
Improvements in neonatal intensive care and the availability of neuroprotective interventions, such as
therapeutic hypothermia, may be improving the long-term outcome for these newborns. BY Extending the
time frame to consider discontinuing Resuscitative efforts
58. Post resuscitation interventions
• Maintain temperature: Avoid overheating the baby during or after resuscitation
In case of severe birth asphyxia related HIE, hypothermia can be beneficial (selection of candidates
for therapeutic hypothermia)
• Continuous monitoring of vital signs (Tº,HR, RR, BP, sPO2,…), respiratory status, urine output,
neurologic status, ABGs,
• Investigations / eventual complications of perinatal distress/asphyxia: RBS, RFTs, Serum
Electrolytes, LFTs, serum PH, Arterial Blood Gas (ABGs), baseline CBC, …
• Assess the need to maintain continuous supplemental oxygen, PPV, or continuous positive
airway pressure (CPAP), or other advanced / specialized interventions, …
59.
60. • Pneumothorax or pleural effusion
• Airway obstruction: thick secretions, MAS, Choanal Atresia, Pierre-Robin
