Neonatal resuscitation (NNR)
Dr. Renu Singh
Burden of the problem
• Birth asphyxia• 23% of the 1 million neonatal deaths in India• Long term neurological complications• Death• NNR (Neonatal resuscitation) :simple,
inexpensive, cost effective method• Problem: NNR often not initiated, incorrect
use of methods
Successful NNR: factors
1. Anticipation: call a skilled personnel2. Adequate preparation3. Accurate evaluation, algorithm based4. Prompt initiation of support
1.Anticipation: High risk delivery • Maternal condition– Advanced maternal age ,DM, HT, stillbirth, fetal loss, early
neonatal death
• Fetal condition– Prematurity, post maturity, congenital anomalies, multiple
gestations
• Ante partum complications: APH, oligo /polyhydramnios
• Delivery complications– Malpresentation, MSAF, instrumental delivery, antenatal
asphyxia with abnormal FHR
2. Adequate preparation
• Radiant warmer is turned on,& is heating• Oxygen source is open with adequate flow
through the tubing• Suction apparatus tested, functioning properly• Laryngoscope is functional with bright light• Resuscitation bag & mask demonstrates an
adequate seal & generation of pressure
Radiant warmer
Successful NNR: factors
1. Anticipation: call a skilled personnel2. Adequate preparation3. Accurate evaluation, algorithm based4. Prompt initiation of support
Evaluation, algorithm based
• Rapid assessment of neonate clinical status
• Is the infant full term?• Is the infant breathing or crying?• Does the infant has good muscle tone?
• Yes: no resuscitation, routine neonatal care• No: needs resuscitation
Approach to resuscitation2010 AHA, AAP
• A: initial steps(provide warmth, clear airway if necessary, dry, stimulate)
• B: breathing(ventilation)• C: chest compressions (circulation)• D: administration of drugs &/or volume
expansion
Resuscitation: initial steps
• Provide warmth• Head position “ sniffing position”• Clearing the airway, if necessary• Drying the baby• Tactile stimulation for breathing
AAP Algorithm
AAP Algorithm
PPV: Positive pressure ventilation
• Form of assisted ventilation• Needed when there is no improvement in HR• Also assess chest wall movements• Should be delivered at rate of 40-60
breaths /min, maintain HR>100 /min• Devices: BMV, ET (endotracheal
tube),LMA(laryngeal mask airway)
Bag & mask ventilation
Endotracheal tube
• If BMV is ineffective/prolonged• When chest compressions are performed• Initial endotracheal suctioning of non vigorous
meconium stained newborn
Endotracheal tube
LMA(Laryngeal mask airway)
• Soft mask, fits over laryngeal inlet when inflated, occludes the oesophageal opening
• Done when BMV is unsuccessful & tracheal intubation is unsuccessful or not feasible
LMA(Laryngeal mask airway)
Targeted SPO2 after birth
1 minute 60-65%
2 minutes 65-70%
3 minutes 70-75%
4 minutes 75-80%
5 minutes 80-85%
10 minutes 85-90%
1. Initial steps in resuscitation2. PPV
AAP Algorithm
Chest compressions
• Started when HR<60 per minute despite adequate ventilation with 100% oxygen for 30 sec
• Delivered at lower third of sternum, to depth 1/3 of AP diameter of chest
• 2 techniques: – 2 thumb-encircling hands technique– Compression with 2 fingers ,second hand
supporting the back– 3:1 ratio::[ 90 comp:30 ventilations]
1. Initial steps of resuscitation2. PPV(ET)3. CHEST COMPRESSIONS
AAP Algorithm
Medications
• Rarely indicated• Most important step to treat bradycardia is
establishing adequate ventilation• HR remains <60bpm,despite adequate
ventilation(ET) with 100% Oxygen & chest compressions
• Epinephrine or volume expansion or both
Epinephrine
• Route of administration: intravenous(IV),ideal• Recommended dose: 0.01-0.03 mg/kg per
dose• Desired concentration: 1:10,000 0.1 mg/ml
Volume expansion
• Suspected or known blood loss• Isotonic crystalloid solution ; normal saline• Blood• Dose calculation: 10 ml/kg
The golden minute
• <30 seconds: complete initial steps• Warmth• Drying• Clear airway if necessary• Stimulate
• 30-60 seconds: assess 2 vital characteristics• Respiration (apnea/gasping/labored/unlabored)• Heart rate (<100/>100bpm)
• Golden Minute Project: skill based training
AAP Algorithm
Post resuscitation care
• Needed for those who required PPV• At risk of deterioration– Hypo/hyperthermia ,hypoglycemia, CNS
complications(apnea, HIE), pulmonary complications(TTN, Pneumonia), hypotension
• Need monitoring ,evaluation• NICU may be necessary
NNR : not indicated
• Conditions with certainly early death• Extreme prematurity(GA<23 weeks)• Birth weight<400g• Anencephaly• Chromosomal abnormality: Trisomy 13
NNR: nearly always indicated
• High rate of survival• Acceptable morbidity• GA≥ 25 weeks• Those with most congenital malformations
NNR?
• Conditions associated with uncertain prognosis
• Survival borderline
• Parental desires concerning initiation of resuscitation should be supported
Discontinuing resuscitative efforts
• Newborn with no detectable heart rate, consider stopping NNR if the heart rate remains undetectable for 10 minutes
Summary
• Most infants transfer from intrauterine to extra uterine life
• 10% need some intervention,1% need extensive resuscitation
• Anticipate the need for NNR• Adequate preparation for NNR• Evaluate the newborn as per AHA/AAP
guidelines & follow the recommended protocol
