Neonatal Resuscitation (NRP) – Full Detailed Guide

1. Definition

Neonatal resuscitation is the set of emergency interventions provided to a newborn immediately after birth to establish:

• Effective breathing
• Adequate heart rate
• Proper oxygenation and circulation

Most babies transition normally, but ~10% need assistance, and ~1% require extensive resuscitation.

2. Physiology of Birth Transition

At birth, the newborn must rapidly shift from placental to lung-based oxygenation:

Key changes:

• Lung fluid clears
• First breaths expand alveoli
• Pulmonary vascular resistance drops
• Blood flow increases through lungs
• Closure of fetal shunts (ductus arteriosus, foramen ovale)

Failure → asphyxia, bradycardia, hypoxia

3. Causes / Risk Factors

Maternal factors:

• Diabetes
• Hypertension
• Infection (chorioamnionitis)
• Prolonged labor

Fetal factors:

• Prematurity
• Growth restriction
• Congenital anomalies

Intrapartum factors:

• Meconium-stained liquor
• Cord prolapse
• Placental abruption
• Shoulder dystocia

4. Preparation Before Delivery

Resuscitation team readiness:

• At least 1 trained person for every delivery
• Extra skilled staff if high-risk birth

Equipment checklist:

• Radiant warmer
• Suction device
• Bag-mask ventilator
• Oxygen blender
• Pulse oximeter
• Endotracheal tubes, laryngoscope
• Umbilical catheter supplies
• Emergency drugs (epinephrine)

5. Initial Rapid Assessment

Immediately after birth ask:

1. Term gestation?
2. Good muscle tone?
3. Breathing or crying?

If YES to all → Routine care

If NO → Start resuscitation

6. Neonatal Resuscitation Algorithm (Stepwise)

Step 1: Initial Stabilization (First 30 sec)

Actions (Warm, Dry, Stimulate):

• Provide warmth (prevent hypothermia)
• Position airway (sniffing position)
• Clear secretions only if obstructing
• Dry thoroughly
• Gentle stimulation

Evaluate:

• Respirations
• Heart rate (HR)
• Color / oxygen saturation

Step 2: Positive Pressure Ventilation (PPV)

Indications:

• Apnea or gasping
• HR < 100 bpm

Technique:

• Bag-mask ventilation
• Rate: 40–60 breaths/min
• Use room air initially in term babies

Oxygen:

• Term: start with 21%
• Preterm: start with 21–30%

Target SpO₂ rises gradually:

• 1 min: 60–65%
• 5 min: 80–85%
• 10 min: 85–95%

Ventilation Corrective Steps (MR SOPA)

If chest not rising:

• Mask adjustment
• Reposition airway
• Suction mouth/nose
• Open mouth
• Pressure increase
• Alternative airway (ET tube/LMA)

Step 3: Chest Compressions

Indication:

• HR < 60 bpm after 30 sec of effective PPV

Method:

• Two-thumb technique on lower sternum

Ratio:

• 3 compressions : 1 ventilation
• 90 compressions + 30 breaths = 120 events/min

Oxygen:

• Increase to 100% during compressions

Step 4: Medications

Indication:

• HR < 60 bpm despite ventilation + compressions

7. Drugs in Neonatal Resuscitation (Detailed)

Epinephrine (Adrenaline)

Indication:

• Severe bradycardia/asystole (HR < 60)

Mechanism:

• α1 vasoconstriction → improves coronary perfusion
• β1 stimulation → increases HR and contractility

Dose:

• IV/umbilical: 0.01–0.03 mg/kg

* (0.1–0.3 mL/kg of 1:10,000 solution)

• Endotracheal (less effective): 0.05–0.1 mg/kg

Pharmacokinetics:

• Rapid onset (seconds IV)
• Short half-life

Adverse effects:

• Tachycardia
• Hypertension
• Arrhythmias

Contraindications:

• None in cardiac arrest

Monitoring:

• HR response every 30 sec

Counselling:

• Emergency life-saving drug only

Volume Expansion (Normal Saline)

Indication:

• Suspected hypovolemia (blood loss, shock)
• Poor perfusion, weak pulses

Dose:

• 10 mL/kg IV over 5–10 min

Adverse effects:

• Fluid overload
• Pulmonary edema

Glucose

Indication:

• Prolonged resuscitation → hypoglycemia risk

Dose:

• D10W bolus 2 mL/kg IV

Naloxone (Rarely Used Now)

Not recommended routinely due to withdrawal risk.

8. Airway Management

Endotracheal Intubation Indications:

• Prolonged PPV
• Need for suction below cords
• Chest compressions
• Suspected diaphragmatic hernia

Tube size:

• <1 kg: 2.5 mm
• 1–2 kg: 3.0 mm
• > 2 kg: 3.5 mm

9. Special Situations

Meconium-Stained Liquor

• No routine suctioning
• If non-vigorous + obstruction suspected → intubation suction

Premature Infant

• Prevent heat loss (plastic wrap)
• Gentle ventilation (avoid lung injury)
• CPAP may help

Congenital Diaphragmatic Hernia

• Avoid bag-mask ventilation
• Immediate intubation

10. Post-Resuscitation Care

After stabilization:

• NICU admission
• Maintain temperature (36.5–37.5°C)
• Monitor glucose, electrolytes
• Continuous oxygen saturation + ECG
• Treat seizures if present
• Consider therapeutic hypothermia if HIE suspected

11. Complications

• Hypoxic ischemic encephalopathy (HIE)
• Pneumothorax
• Pulmonary hemorrhage
• Intracranial hemorrhage (preterm)
• Long-term neurodevelopmental delay

12. Key Take-Home Points

• Ventilation is the most important step
• Most newborns respond to PPV alone
• Chest compressions only if HR < 60
• Epinephrine is last step after effective ventilation
