Neonatal Resuscitation (Pediatric)

1. Definition

Neonatal resuscitation refers to a series of interventions performed at birth to support airway, breathing, and circulation in newborns who fail to establish effective spontaneous respiration or adequate heart rate after delivery.

About 10% of newborns require some assistance to begin breathing, while 1% require extensive resuscitation measures.

2. Goals of Neonatal Resuscitation

1. Establish effective ventilation
2. Maintain adequate oxygenation
3. Support cardiac output and circulation
4. Prevent hypoxia and acidosis
5. Maintain normal body temperature

3. Physiological Changes at Birth

At birth the neonate must transition from placental circulation to pulmonary respiration.

Key changes:

| Fetal State | Neonatal State |

| ------------------------------------------------------- | ---------------------------- |

| Placenta provides oxygen | Lungs provide oxygen |

| High pulmonary vascular resistance | Low pulmonary resistance |

| Right-to-left shunts (ductus arteriosus, foramen ovale) | Functional closure of shunts |

| Fluid-filled lungs | Air-filled lungs |

Failure of this transition leads to asphyxia requiring resuscitation.

4. Indications for Neonatal Resuscitation

Resuscitation is required if any of the following are present:

• Apnea or gasping

• Heart rate <100 beats/min

• Poor muscle tone

• Cyanosis or persistent low oxygen saturation

• Poor respiratory effort

5. Risk Factors for Neonatal Depression

Maternal factors

• Diabetes

• Hypertension

• Infection

• Sedative drugs

• Antepartum hemorrhage

Intrapartum factors

• Prematurity

• Meconium-stained amniotic fluid

• Prolonged labor

• Cord prolapse

• Placental abruption

Fetal factors

• Congenital anomalies

• Intrauterine growth restriction

• Multiple gestation

6. Preparation Before Delivery

Team

Minimum one skilled person trained in neonatal resuscitation must be present.

Equipment

Airway:

• Suction device

• Bulb syringe

• Laryngoscope

• Endotracheal tubes

Breathing:

• Self-inflating bag

• T-piece resuscitator

• Oxygen source

Circulation:

• Umbilical venous catheter

• Medications (epinephrine)

Thermal control:

• Radiant warmer

• Warm towels

Monitoring:

• Pulse oximeter

• Stethoscope

• ECG monitor

7. Initial Assessment Immediately After Birth

Three questions are asked:

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

If YES to all → routine care

If NO → begin resuscitation

8. Initial Steps of Resuscitation (Golden Minute)

Must be completed within first 60 seconds.

Steps:

1. Provide warmth
2. Position airway (sniffing position)
3. Clear secretions if needed
4. Dry the baby
5. Stimulate breathing

9. Airway Management

Position

Head in sniffing position to maintain airway patency.

Suctioning

Indications:

• Obstructed airway

• Excess secretions

Order:

1. Mouth
2. Nose

Suction pressure:

<100 mmHg

Routine suction for meconium is not recommended unless airway obstruction is present.

10. Breathing Support

If after initial steps:

• Apnea

• Gasping

• HR <100 bpm

→ Start Positive Pressure Ventilation (PPV)

Method

Bag and mask ventilation.

Ventilation parameters

| Parameter | Value |

| -------------- | --------------------------- |

| Rate | 40–60 breaths/min |

| Initial oxygen | 21% (room air) in term baby |

| Preterm oxygen | 21–30% |

| Peak pressure | 20–25 cm H₂O |

Goal: chest rise and HR improvement

11. Assessment After 30 Seconds of PPV

Check heart rate.

| Heart Rate | Action |

| ---------- | ------------------------ |

| ≥100 bpm | Stop PPV, observe |

| 60–99 bpm | Continue PPV |

| <60 bpm | Start chest compressions |

12. Chest Compressions

Indication:

Heart rate <60 bpm despite effective ventilation for 30 seconds

Technique

Two-thumb encircling method preferred.

Compression location:

Lower third of sternum.

Ratio

3 compressions : 1 ventilation

Rate

120 events/min

(90 compressions + 30 breaths)

Depth:

1/3 of chest diameter

13. Reassessment

After 60 seconds of compressions + ventilation

Check heart rate.

| HR | Action |

| ------- | ----------------- |

| ≥60 bpm | Stop compressions |

| <60 bpm | Give medications |

14. Medications

1. Epinephrine

Indication

Heart rate <60 bpm after ventilation and chest compressions

Mechanism

Alpha and beta adrenergic agonist → increases heart rate and contractility.

Dose

IV: 0.01–0.03 mg/kg

Concentration:

1:10,000 (0.1 mg/mL)

Route

Preferred: Umbilical vein

Adverse effects

• Hypertension

• Arrhythmia

• Myocardial ischemia

Monitoring

Heart rate and blood pressure.

2. Volume Expansion

Indication:

Suspected hypovolemia or blood loss

Fluid:

Normal saline

Dose:

10 mL/kg IV

15. Oxygen Saturation Targets After Birth

| Time after birth | Target SpO₂ |

| ---------------- | ----------- |

| 1 min | 60–65% |

| 2 min | 65–70% |

| 3 min | 70–75% |

| 4 min | 75–80% |

| 5 min | 80–85% |

| 10 min | 85–95% |

16. Advanced Airway Management

Indications for intubation:

• Ineffective mask ventilation

• Need for prolonged PPV

• Chest compressions required

• Congenital diaphragmatic hernia

Endotracheal tube size:

| Weight | Tube Size |

| ------ | ---------- |

| <1 kg | 2.5 mm |

| 1–2 kg | 3.0 mm |

| 2–3 kg | 3.5 mm |

| >3 kg | 3.5–4.0 mm |

17. Post-Resuscitation Care

Newborns needing resuscitation must be monitored for:

• Hypoglycemia

• Hypothermia

• Hypoxia

• Seizures

• Organ dysfunction

Management includes:

• Oxygen therapy

• IV fluids

• Glucose monitoring

• NICU admission

18. Complications of Birth Asphyxia

• Hypoxic ischemic encephalopathy

• Seizures

• Cerebral palsy

• Multiorgan failure

• Death

19. APGAR Score

Evaluated at 1 minute and 5 minutes

| Parameter | Score 0 | Score 1 | Score 2 |

| ------------------- | ------- | ------------ | --------------- |

| Heart rate | Absent | <100 | ≥100 |

| Respiration | Absent | Slow | Good cry |

| Muscle tone | Flaccid | Some flexion | Active |

| Reflex irritability | None | Grimace | Cry |

| Color | Blue | Body pink | Completely pink |

Score interpretation:

• 7–10 : Normal

• 4–6 : Moderate depression

• 0–3 : Severe depression

20. Neonatal Resuscitation Algorithm (Summary)

1. Birth → assess breathing, tone, gestation
2. Initial steps (warm, dry, stimulate)
3. If HR <100 → PPV
4. After 30 sec → check HR
5. HR <60 → chest compressions
6. If still <60 → epinephrine

If you want, I can also give 20–30 difficult NEET PG / USMLE / Pediatric residency MCQs on Neonatal Resuscitation, which are commonly asked in exams.
