Globally, about one quarter of all neonatal deaths are caused by birth asphyxia. Effective resuscitation at birth can prevent a large proportion of these deaths.
About 10% of all new born require some assistance to begin breathing just after delivery.
<1% of them require extensive resuscitation
Ref: BMC Public Health 2011 11(Suppl 3):S12
Basic Neonatal Resuscitation
1. Airway support
2. Breathing/ventilation
Advanced Neonatal Resuscitation
1. All the steps of basic neonatal resuscitation
2. Chest compression
3. Endotracheal intubation
4. Vascular cannulation
5. The use of drugs & fluids
Following scheme is recommended1.Preparation 2.Safety3.Shout for help4.Stimulate
1. Dry & rub the back with towel and cover the newborn
2. Gentle verbal / tactile stimuli in a neonate
5.Assess for breathing (crying/movement of chest)
6.Airway 1. Open 2. Clear
7. Reassess for breathing

14. post-resuscitation care
Is the key to a successful outcome. Cooperation between obstetric and pediatric
staff is important. Review notes Communicate with the parents Wash hands & Use sterile gloves Thermoneutral environment Check for equipment

1. Ensure your own as well as patient’s
safety
2. Look for the clues as to what may have
caused this emergency.
3. Wear gloves & do not perform direct
mouth to mouth breathing.
Do not hesitate to call for help
especially in high risk situations.
IN CASE OF NEWBORN: 1- Start the clock Timing to cut the cord Ascertain the duration of CPR 2- Dry the baby 3- Assess for breathing 4- Stimulate if not breathing 5- If baby starts breathing/ crying, no further help 6- if no response, then proceed furtherIN CASE OF NEONATE:
Stimulate the baby by gentle shaking of arms or rubbing of skin or by verbal stimuli
Assessment & reassessment is done after
every 30 seconds, and take no longer than 10
seconds.
Look: Chest movements
Listen: Breath sounds & heart sounds (auscultation)
Feel: Breaths and pulse
Open airway by Neutral position Chin lift Jaw thrust
Clear airway secretions, foreign body, vomits by
gentle suctioning of mouth first and then
nose.
In newborns after the airway is opened and cleared and the newborn is still not breathing, then it is necessary to aerate the lungs first with “inflation breaths” and then to continue with ‘ventilation breaths’
In case of a neonate inflation breaths are not required. Only ventilation breaths, called ‘rescue breaths’, are given.
Ventilation / rescue breaths are given at the rate 30/min.
Effective ventilation: Good chest movement Improvement of heart rate within 20-30 seconds
Chest compression is indicated
when heart rate <60/min despite of
adequate chest expansion with
ventilation, for 30 seconds.
Ventilation / rescue breaths need to be
continued alongside chest
compressions.
Technique Two thumbs technique Two fingers technique
At lower third sternum (between the xiphoid and a line draw between nipples)
Compression depth; approximately one third of the anterio-posterior diameter of chest
Duration of downward stroke of compression should be shorter than duration of release.
Don’t lift your thumbs or fingers off the chest between two compressions.
Chest compression must always be accompanied by positive pressure ventilation.
One ventilation interposed after every third compression (1:3).
Total of 30 breaths and 90 compression per minutes (120 events per minute)
One and two and three and breath and ……..
If heart rate not improving(below
60/min) despite adequate ventilation
and chest compressions for 30 seconds
then drugs should be considered.
Drug must be followed by 0.5-1.0 ml normal saline to clear the drug from catheter.
ADRENALINE: Preparation: 1:10,000 (1g/10,000ml,
100mg/l or 100µg/ml) Dose: 10µg/kg, 0.1ml-0.3 ml/kg (0.5-1.0
ml/kg via endotracheal tube) Route: Umbilical venous catheter or
endotracheal tube Rate: Rapidly
SODIUM BICARBONATE: Preparation: 4.2% (or 8.4% diluted 1:1) Dose: 1-2 mmol/kg (2-4ml/kg) Route: umbilical venous catheter Rate: 1mmol/kg/min
VOLUME EXPANDERS: Preparation:
Normal saline Ringer lactate O negative blood, cross matched with mother’s blood if
time permits (if prenatal diagnosis has suggested low fetal blood volume)
Dose: 10 ml/kg Route: Umbilical vein Rate: over 5-10 min
DEXTROSE Preparation: 10%
Dose: 250 mg/kg or 2.5 ml/kg
Route: umbilical vein
Reassess after every 30 seconds, and
take no longer than 10 seconds.
1. Ambu bagging not effective2. Prolonged ventilation is expected3. Suspected diaphragmatic hernia 4. Severe anatomical or functional upper
airway obstruction5. Need for high pressure to maintain
adequate oxygenation 6. Need for bronchial or tracheal suctioning
in meconium stained un-responsive baby7. Instability or high probability of any of
the above occurring before or during transport.
Different methods are used for its calculation
Formula 1:gestational age (weeks)/ 10 Formula 2:
Tube size Weight (g) Gestational age (wk)
2.5 < 1,000 < 28
3.0 1,000-2,000 28-34
3.5 2,000-3,000 34-38
3.5-4.0 >3,000 >38
Different methods are used for its calculation
Formula 1: baby’s weight (in kilograms) + 6
Formula 2: Length of tube according to weightWeight Depth of insertion
(in cm from upper lip)

1. The conditions suitable for a neonate should be maintained during the transfer.
2. Transferring team must be able to deal with any problems arising during transportation.
3. The receiving hospital should be informed before departure.
1. Monitor vital signs, glucose
2. Monitor events & complications
3. Care of endotracheal tube & vascular lines
4. Skin to skin contact with mother where
possible
5. Reassess the baby as required
6. Keep record
7. Communicate with parents

Reassess (every 30 sec)Regular breathing, good HR
Continue CC, ventilation / rescue breaths
Consider drugs
Reassess (every 30 sec)
Good HR Slow HR
Slow heart rate
Abandon resuscitation after 10 minutes of undetectable HR
Effective spontaneous breathing has been established as evidenced by: Increasing heart rate Spontaneous breathing
Senior staff and parents must be consulted before stopping positive pressure ventilation in cases of: Signs of established biological death The existence of DNR is established If there is no detectable heart rate for >10 min
despite adequate measures
Standard algorithm of ‘ABCD’ is used but
with minimal variation.
Attempts to aspirate meconium from nose & mouth of the unborn baby , while the head is still on the perineum is not recommended.
If at birth, a meconium stained baby has: Normal respiratory effort normal muscle tone heart rate grater than 100beats/min
Intervention:1. Use a bulb/penguin sucker or large bore suction
catheter to clear secretions from oropharynx and nose.
2. Do not intubate or do blind oropharyngeal suction.
If at birth, a meconium stained baby has: depressed respiration depressed muscle tone heart rate <100 beats/min Intervention:1. immediate endotracheal intubation and
direct suctioning of trachea is done without stimulation.
2.
Results from:Positive pressure ventilationLung malformation
If the chest is not expanding adequately despite proper positioning of airways , ambu-bagging, giving adequate pressure, placing Guedel airways and there is no improvement in heart rate, then this condition must be considered.
Removing obstruction of lung airways by external chest drainage of air through placement of needle or chest drain in pleural space.
In neonate it may results from:Hydrops fetalisChylothorax
Manage by chest drain insertion.
If Chest is not expanding adequately despite proper positioning of airways, ambu-baging, giving adequate pressure, placing Guedel airways and there is no improvement in heart rate.
Think CDH and confirm on examination.
Resuscitation with a bag and mask contraindicated.
Should have immediate endotracheal intubation and place a large orogastric catheter.
Babies are nasal breathers.
Should be considered where after proper airway opening and clearing maneuvers, good expansion of the chest cannot be obtained by ambu-baging.
Intervention:
Inserting a plastic oral airway will allow air to pass through mouth.
Developmental malformation of palate and oropharynx.
Small mandible results in critical narrowing of pharyngeal airway.
Tongue, posteriorly placed, falls back into pharynx and obstructs it just above larynx.
Maintain airway by positioning or use of plastic oral airway.
Get hypothermic earlier than term babies.
Fragile lungs and thus inability to breath effectively.
Maintain body temperature during resuscitation and use lower pressures for chest expansion.
Naloxone is no longer recommended as part of initial resuscitation in a delivery room.
Giving a narcotic antagonist is not the
correct first therapy for a baby who is not breathing.
The first corrective action is positive pressure ventilation.
Indications: 1. Continued respiratory depression after PPV has
restored a normal HR. 2. A history of maternal narcotic administration
during labour within 4 hours.
Naloxone : DOSE : 0.1 mg/kg I/V bolus.
Caution: Do Not give Naloxone to the newborn whose mother is suspected of being addicted to narcotics.
