Neonatal Resuscitation

Quick Reference

Critical Alerts

Critical Point: Most newborns do NOT require resuscitation: Approximately 85-90% of term newborns transition successfully to extrauterine life without any intervention. [1,2]

Critical Point: Ventilation is the cornerstone: The single most important and effective action in neonatal resuscitation is achieving adequate lung inflation. Heart rate almost always improves with effective positive pressure ventilation (PPV). [1,3]

Critical Point: The Golden Minute: Initial steps (warmth, dry, stimulate, assess) should be completed within the first 60 seconds of life. PPV should begin by 60 seconds if the newborn remains apneic or has HR less than 100 bpm. [1]

Critical Point: Room air for term infants initially: Current guidelines recommend initiating resuscitation with 21% oxygen for term infants, titrating to preductal SpO2 targets. Routine use of 100% oxygen is no longer recommended due to oxidative stress concerns. [1,2,4]

Critical Point: Delayed cord clamping: For vigorous term and preterm newborns, delay cord clamping for at least 30-60 seconds to optimize placental transfusion, improve iron stores, and reduce intraventricular hemorrhage risk. [1,5,6]

Critical Point: Epinephrine: IV/IO preferred route: 0.01-0.03 mg/kg (1:10,000 concentration). Endotracheal route requires higher doses (0.05-0.1 mg/kg) and is less reliable. [1,7]

Definition and Overview

Clinical Definition

Neonatal resuscitation encompasses the systematic, evidence-based interventions provided to newborns who fail to establish spontaneous and adequate respiration at birth or who demonstrate cardiovascular compromise during the transition from intrauterine to extrauterine life. [1,2]

The Neonatal Resuscitation Program (NRP) developed by the American Academy of Pediatrics (AAP) and American Heart Association (AHA) provides the international standard for delivery room resuscitation, with the most recent major update in 2020. [1]

Classification of Newborn Transition

Normal Transition (85-90% of newborns):

• Spontaneous breathing within 30 seconds
• Heart rate > 100 bpm
• Central cyanosis resolving by 5-10 minutes
• Good muscle tone

Requires Basic Intervention (5-10%):

• Drying, warming, stimulation
• Airway positioning
• Brief PPV

Requires Advanced Resuscitation (less than 1%):

• Prolonged PPV with intubation
• Chest compressions
• Medications (epinephrine, volume)

NRP Algorithm Framework

The structured approach follows a stepwise escalation:

1. Initial Steps (0-60 seconds): Warmth, position, clear airway, dry, stimulate
2. Positive Pressure Ventilation: If apnea or HR less than 100 after initial steps
3. Chest Compressions + PPV: If HR less than 60 after 30 seconds of effective PPV
4. Medications: If HR less than 60 after 60 seconds of coordinated compressions + PPV

Epidemiology

Global Burden

Birth asphyxia and related complications account for approximately 23% of neonatal deaths worldwide, representing over 650,000 deaths annually. [8] The majority of these deaths occur in low and middle-income countries where access to skilled birth attendants and resuscitation equipment is limited.

Pathophysiology

Normal Fetal-to-Neonatal Transition

The transition from intrauterine to extrauterine life involves profound cardiopulmonary changes that must occur within minutes of birth:

Pulmonary Adaptation:

1. Lung fluid clearance: Approximately 30 mL/kg of fetal lung fluid must be absorbed, primarily through sodium channels in alveolar epithelium, driven by catecholamine surge during labor. [9]
2. Establishment of functional residual capacity (FRC): First breaths generate negative intrathoracic pressures of -40 to -100 cm H2O to inflate fluid-filled alveoli.
3. Surfactant activation: Surface tension reduction permits alveolar stability.

Circulatory Adaptation:

1. Pulmonary vasodilation: Oxygen and mechanical lung expansion trigger dramatic decrease in pulmonary vascular resistance (PVR).
2. Increased systemic vascular resistance: Cord clamping removes low-resistance placental circulation.
3. Foramen ovale closure: Functional closure occurs as left atrial pressure exceeds right atrial pressure.
4. Ductus arteriosus constriction: Oxygen exposure and prostaglandin withdrawal trigger ductal closure.

Pathophysiology of Failed Transition

When normal transition fails, a predictable sequence of deterioration occurs:

Primary Apnea:

• Initial gasping followed by cessation of breathing
• Heart rate decreases but remains above 60 bpm
• Responds to stimulation and PPV
• Typically reversible with basic intervention

Secondary Apnea:

• Follows unrelieved primary apnea
• Progressive bradycardia (less than 60 bpm)
• Hypotension and poor perfusion
• Does NOT respond to stimulation alone
• Requires PPV and potentially compressions

Exam Detail: The Apnea-Bradycardia-Hypoxia Cycle: Failed lung inflation → Hypoxemia → Pulmonary vasoconstriction → Persistent fetal circulation → Right-to-left shunting → Worsening hypoxemia → Myocardial hypoxia → Bradycardia → Decreased cardiac output → Multi-organ hypoxic injury

This cycle emphasizes why effective VENTILATION is the key intervention - establishing lung inflation reverses the cascade.

Molecular Mechanisms of Hypoxic Injury

Prolonged hypoxia-ischemia triggers a cascade of cellular injury:

1. Energy failure: ATP depletion from anaerobic metabolism
2. Excitotoxicity: Glutamate accumulation and NMDA receptor activation
3. Calcium influx: Activation of destructive enzymes
4. Free radical generation: Oxidative stress (particularly during reperfusion)
5. Inflammatory response: Microglial activation and cytokine release
6. Apoptosis/Necrosis: Programmed and unprogrammed cell death

This understanding underpins the rationale for therapeutic hypothermia, which attenuates multiple steps in this cascade. [10,11]

Preparation and Anticipation

Pre-Delivery Preparation

Every delivery should be attended by at least one person trained in neonatal resuscitation whose primary responsibility is the newborn. [1]

For high-risk deliveries, a full resuscitation team should be present:

• Leader (coordinates, monitors, communicates)
• Airway manager (PPV, intubation)
• Circulation support (compressions, medications)
• Monitor/recorder

Equipment Checklist

Thermoregulation:

• Radiant warmer (preheated)
• Warm blankets/towels
• Plastic wrap/bag for preterm infants (less than 32 weeks)
• Chemical warming mattress (optional)
• Temperature probe and thermometer

Airway Management:

Medications and Vascular Access:

Initial Steps - The Golden Minute

Step 1: Provide Warmth

Prevention of hypothermia is critical - cold stress increases oxygen consumption and metabolic acidosis, worsening outcomes.

Term Infants:

• Radiant warmer (preheated)
• Dry thoroughly with warm towels
• Remove wet linens immediately
• Place skin-to-skin with mother if vigorous

Preterm Infants (less than 32 weeks):

• Polyethylene plastic wrap/bag without drying (except head)
• Increase delivery room temperature to 23-25°C
• Consider thermal mattress
• Target temperature: 36.5-37.5°C

Clinical Pearl: Preterm infants lose heat rapidly due to high surface area-to-volume ratio, thin skin, and minimal subcutaneous fat. The plastic wrap technique reduces evaporative heat loss by up to 90% and is evidence-based practice. [12]

Step 2: Position and Clear Airway

Optimal Position:

• Supine with head in neutral "sniffing" position
• Slight neck extension (avoid hyperextension or flexion)
• Small shoulder roll (1-2 cm) may help in preterm infants

Airway Clearance:

• Gentle suctioning ONLY if obvious obstruction
• Mouth before nose (prevents aspiration of oral secretions during gasping)
• Limit suction to 10 seconds
• Avoid deep pharyngeal suctioning (causes vagal bradycardia)

Critical Point: Routine suctioning is no longer recommended - even for meconium-stained amniotic fluid in vigorous infants. Aggressive suctioning can cause vagal bradycardia, mucosal injury, and delays initiation of ventilation. [1,13]

Step 3: Dry and Stimulate

• Dry thoroughly while suctioning/positioning
• Additional stimulation: Flicking soles of feet, rubbing back
• Stimulation should be brief (10-15 seconds maximum)
• If no response to stimulation → assume secondary apnea → begin PPV

Step 4: Assess Response

At 30 seconds and again at 60 seconds:

1. Breathing: Crying, regular respirations, apnea, or gasping?
2. Heart rate: Use auscultation, pulse oximetry, or ECG
   • Auscultation at left chest/apex remains the gold standard for initial assessment
   • ECG provides most accurate continuous monitoring
   • Pulse oximetry may have 60-90 second delay in signal acquisition

Decision Point at 60 seconds:

• If breathing AND HR ≥100 → Routine care, monitoring
• If apneic or gasping OR HR less than 100 → Begin PPV immediately

---

Delayed Cord Clamping

Current Recommendations

The 2020 AHA/AAP guidelines recommend delayed cord clamping (DCC) for all vigorous term and preterm newborns:

Physiological Benefits

Placental Transfusion Effects:

• Transfer of 25-35 mL/kg blood volume
• 30-50 mg/kg iron stores (prevents iron deficiency for 6-8 months)
• Higher hemoglobin levels at birth

Preterm-Specific Benefits: [5,6]

• Reduced intraventricular hemorrhage (IVH)
• Reduced need for blood transfusion
• Improved transitional circulation
• Lower incidence of necrotizing enterocolitis (NEC)

Term Infant Benefits:

• Improved iron stores at 3-6 months
• Reduced iron deficiency anemia
• Better neurodevelopmental outcomes in some studies

Umbilical Cord Milking

Alternative when DCC not feasible (emergency cesarean, maternal hemorrhage):

• Strip cord toward infant 2-4 times over 2-3 seconds
• Provides similar volume of placental transfusion
• Note: Avoided in less than 28 weeks gestation due to IVH concerns in some studies

Evidence Debate: Active vs. Passive Cord Milking in Extremely Preterm Infants: Recent evidence suggests intact umbilical cord milking may be associated with increased severe IVH risk in infants less than 28 weeks. The PREMOD2 trial was stopped early due to safety concerns. Current guidance recommends caution with milking in this population, favoring DCC when possible or cut-cord milking if immediate resuscitation is required. [6]

Positive Pressure Ventilation

Indications for PPV

PPV should be initiated if, after completing initial steps:

• Apnea or gasping respirations
• Heart rate less than 100 bpm despite stimulation

PPV Technique

Device Options:

Ventilation Parameters:

Assessment of Effective Ventilation

Signs of Adequate Ventilation:

1. Visible chest rise (most important indicator)
2. Improving heart rate (primary target)
3. Improving oxygen saturation
4. Improving color and tone

If No Chest Rise → MR SOPA Corrective Steps:

M - Mask Adjustment:

• Ensure proper size (covers chin to bridge of nose)
• Create seal by applying gentle downward pressure
• Use two-handed technique if needed (jaw thrust with mask held by assistant)

R - Reposition Airway:

• Ensure neutral position (avoid flexion or hyperextension)
• Use shoulder roll for preterm infants
• Lift chin/jaw forward

S - Suction:

• Suction mouth then nose
• Limit duration to 10 seconds
• Use appropriate pressure (80-100 mmHg)

O - Open Mouth:

• Slightly open infant's mouth
• Can use oropharyngeal airway if tongue obstructing

P - Pressure Increase:

• Increase PIP by 5-10 cm H2O increments
• First breaths may require higher pressures
• Maximum 40 cm H2O for term infants

A - Alternate Airway:

• Consider endotracheal intubation
• Laryngeal mask airway (LMA) for infants ≥34 weeks or > 2000g
• LMA cannot be used for suctioning or medication delivery

Clinical Pearl: The Two-Person Technique: When mask ventilation is challenging, one person applies the mask using both hands (E-C technique with jaw thrust) while a second person squeezes the bag. This dramatically improves mask seal and airway patency.

Oxygen Management

Rationale for Room Air Initiation: [4,14]

Randomized controlled trials and meta-analyses have demonstrated:

• No survival benefit from 100% oxygen
• Room air (21%) is as effective as 100% oxygen for term resuscitation
• High oxygen exposure causes oxidative stress
• Hyperoxia may worsen reperfusion injury
• Time to first breath and establishment of spontaneous breathing similar

Titration Strategy:

• Start at 21% for term, 21-30% for preterm
• Apply pulse oximeter to right hand/wrist (preductal)
• Increase FiO2 if not meeting targets
• Decrease FiO2 if exceeding targets
• Target SpO2 values based on minute of life

---

Endotracheal Intubation

Indications

Equipment Selection

ETT Size by Gestational Age/Weight:

Insertion Depth Formula:

• Nasal-tragus length + 1 cm
• OR: Weight (kg) + 6 cm (for oral intubation)

Laryngoscope Blade Selection:

• Miller 0: Preterm infants
• Miller 1: Term infants
• Straight blades preferred for neonates (lifts epiglottis)

Confirmation of Placement

Primary Confirmation:

1. CO2 detection (colorimetric or capnography) - MOST RELIABLE

   • Color change yellow = CO2 detected = esophageal intubation ruled out
   • May be false negative in cardiac arrest (no pulmonary blood flow)

2. Clinical Assessment:

   • Visible chest rise
   • Bilateral equal breath sounds
   • Improving heart rate
   • Misting of ETT

Secondary Confirmation:

• Chest X-ray (tip at T1-T2, above carina)
• Note: CXR should not delay resuscitation

Laryngeal Mask Airway (LMA)

Indications:

• Failed intubation and ineffective mask ventilation
• Infants ≥34 weeks gestation or > 2000g
• Normal airway anatomy

Limitations:

• Cannot use for tracheal suctioning
• Cannot deliver endotracheal medications
• Not suitable for very preterm or very small infants

---

Chest Compressions

Indications

Critical Point: Chest compressions are indicated when the heart rate remains less than 60 bpm after 30 seconds of effective PPV with visible chest movement. This emphasizes that ventilation must be established FIRST - most neonates with bradycardia respond to ventilation alone. [1,3]

Technique

Recommended Method - Two-Thumb Encircling Technique:

• Thumbs on lower third of sternum (just below nipple line)
• Fingers encircle chest, supporting back
• Compress to 1/3 anterior-posterior diameter of chest
• Allow full chest recoil between compressions

Alternative - Two-Finger Technique:

• Two fingers on lower third of sternum
• Other hand supports back
• Used when umbilical catheter is being placed

Compression-to-Ventilation Ratio:

• 3:1 ratio (different from pediatric/adult 15:2 or 30:2)
• 90 compressions + 30 ventilations = 120 events/minute
• Rhythm: "One-and-Two-and-Three-and-Breathe"

Exam Detail: Why 3:1 in Neonates? Neonatal cardiac arrest is almost always due to respiratory failure (hypoxic arrest) rather than primary cardiac arrhythmia. Therefore, ventilation is prioritized over compressions. The 3:1 ratio optimizes oxygen delivery while maintaining cardiac output. Animal studies suggest this ratio provides better outcomes in asphyxia models than higher compression ratios. [1,15]

Exception: In cases of suspected primary cardiac etiology (known congenital heart disease, arrhythmia), a higher ratio (15:2) may be considered.

Coordination with Ventilation

• Intubation strongly recommended before/during compressions for synchronization
• Pause compressions briefly for ventilation (not continuous compression)
• Assess heart rate every 60 seconds
• Discontinue compressions when HR ≥60 bpm

Duration and Reassessment

• Reassess heart rate after 60 seconds of coordinated compressions + ventilation
• If HR ≥60 → Discontinue compressions, continue PPV
• If HR still less than 60 → Administer epinephrine, continue CPR
• Consider reversible causes (HOTT - Hypovolemia, Obstruction, Tension pneumothorax, cardiac Tamponade)

---

Medications

Epinephrine (Adrenaline)

Mechanism: Alpha-adrenergic vasoconstriction increases diastolic blood pressure and coronary perfusion pressure during CPR; beta-adrenergic effects increase heart rate and contractility.

Indication: Heart rate remains less than 60 bpm after at least 60 seconds of effective ventilation AND chest compressions.

Dosing: [1,7]

Administration:

• IV route via umbilical venous catheter is fastest and most reliable
• Flush with 0.5-1 mL normal saline after administration
• May repeat every 3-5 minutes if HR remains less than 60
• Maximum single dose: 0.03 mg/kg IV or 0.1 mg/kg ET

Critical Point: IV/IO is the preferred route because absorption from the trachea is unpredictable and lower plasma levels are achieved. The 2020 guidelines emphasize establishing vascular access promptly if anticipating need for epinephrine. While waiting for IV access, an initial dose via ETT may be given, but IV dosing should follow as soon as access is obtained. [1,7]

Volume Expansion

Indication: Suspected hypovolemia with signs of shock (pallor, weak pulses, poor perfusion, no response to resuscitation) AND history suggesting blood loss.

Causes of Hypovolemia:

• Placental abruption
• Placenta previa
• Cord avulsion
• Fetomaternal hemorrhage
• Vasa previa
• Traumatic delivery

Fluid Choice:

• Normal saline (0.9% NaCl) - first line
• O-negative packed red blood cells (if severe blood loss suspected)
• Lactated Ringer's solution (acceptable alternative)

Dosing:

• 10 mL/kg IV bolus
• Administer over 5-10 minutes
• May repeat if inadequate response
• Avoid excessive volume in preterm infants (risk of IVH)

Sodium Bicarbonate

• NOT routinely recommended in acute neonatal resuscitation
• May be considered only after prolonged arrest with documented metabolic acidosis
• If used: 1-2 mEq/kg of 4.2% solution (0.5 mEq/mL) slow IV
• Risk of intracranial hemorrhage, paradoxical intracellular acidosis

Naloxone

• NOT recommended as part of initial resuscitation
• Risk of acute withdrawal seizures in infants of opioid-dependent mothers
• PPV should support respiration regardless of maternal opioid exposure
• May be considered later (post-resuscitation) in specific circumstances

Glucose

• NOT given during acute resuscitation (no indication for dextrose bolus)
• Hypoglycemia should be assessed and treated in post-resuscitation period
• Target blood glucose: 40-50 mg/dL minimum (> 2.2-2.8 mmol/L)

---

Umbilical Venous Catheter (UVC) Placement

Indication

Emergency vascular access for epinephrine and volume administration during resuscitation.

Technique

1. Clean umbilical stump with antiseptic solution
2. Place sterile tie around base of cord loosely
3. Cut cord 1-2 cm from skin with sterile blade
4. Identify vessels: 1 large, thin-walled vein (at 12 o'clock); 2 smaller, thick-walled arteries
5. Insert catheter (3.5-5F) into umbilical vein
6. Advance just until blood return (2-4 cm) - do not advance far in emergency
7. Aspirate to confirm blood return
8. Flush and secure

Tips for Emergency UVC

• Keep catheter insertion depth shallow (just past abdominal wall)
• Deep insertion risks hepatic vein placement and liver injury
• If resistance encountered, do not force
• Alternative: Intraosseous access at proximal tibia

Meconium-Stained Amniotic Fluid

Updated Approach (2020 Guidelines)

The management of meconium-stained amniotic fluid (MSAF) has changed significantly based on evidence that routine tracheal suctioning does not improve outcomes. [1,13,16]

For Vigorous Newborns

Definition of Vigorous: Good muscle tone, breathing or crying, HR > 100 bpm

Management:

• NO routine suctioning (including intrapartum oropharyngeal/nasopharyngeal suctioning)
• Standard initial steps (dry, warm, stimulate)
• Observation for respiratory distress
• Routine care if remains well

For Non-Vigorous Newborns

Definition of Non-Vigorous: Depressed tone, apneic or gasping, HR less than 100 bpm

Management:

• Standard initial steps
• Begin PPV if apneic or HR less than 100
• If airway obstruction suspected (no chest rise despite corrective ventilation steps) → Consider intubation and tracheal suctioning
• Do NOT delay PPV for suctioning

Evidence Debate: Routine Tracheal Suctioning is No Longer Recommended The 2015 and 2020 guidelines moved away from routine intubation and tracheal suctioning for non-vigorous infants born through meconium-stained fluid. The evidence showed:

• No improvement in mortality or morbidity with routine suctioning
• Delayed initiation of ventilation with suctioning protocol
• Tracheal suctioning does not prevent meconium aspiration syndrome (MAS) if already aspirated in utero

Intubation and suctioning should now only be considered if there is suspected airway obstruction preventing effective ventilation. [13,16]

Meconium Aspiration Syndrome (MAS)

Pathophysiology:

• Mechanical obstruction (complete or ball-valve)
• Chemical pneumonitis
• Surfactant inactivation
• Pulmonary hypertension (PPHN)

Management of Established MAS:

• Supportive respiratory care (supplemental O2, CPAP, mechanical ventilation)
• Surfactant replacement (may be beneficial)
• Inhaled nitric oxide for PPHN
• ECMO for refractory hypoxemia
• Therapeutic hypothermia if HIE criteria met

---

Post-Resuscitation Care

Immediate Post-Resuscitation Monitoring

Laboratory Assessment

Immediately Post-Resuscitation:

• Blood gas (arterial or capillary) - pH, pCO2, base deficit, lactate
• Blood glucose
• Complete blood count
• Blood culture (if sepsis suspected)

Within First Hours:

• Electrolytes, BUN, creatinine
• Liver function tests
• Coagulation studies (if prolonged resuscitation or bleeding)
• Cardiac enzymes (if cardiac injury suspected)

Disposition

NICU Admission Criteria:

• Any infant requiring more than brief PPV
• Preterm infant less than 35 weeks
• Ongoing respiratory distress
• Hemodynamic instability
• Suspected sepsis
• Encephalopathy or neurologic concerns
• Hypoglycemia requiring IV dextrose
• Need for further investigation or monitoring

---

Therapeutic Hypothermia for HIE

Hypoxic-Ischemic Encephalopathy (HIE)

HIE occurs when hypoxia-ischemia during the perinatal period causes brain injury with characteristic encephalopathy. It affects 1-6 per 1000 term births and is a leading cause of neonatal mortality and long-term neurodevelopmental disability. [10,11,17]

Therapeutic Hypothermia - Mechanism

Hypothermia (cooling to 33-34°C) is neuroprotective through multiple mechanisms:

• Reduced cerebral metabolic rate
• Decreased excitatory neurotransmitter release
• Reduced inflammatory cytokine production
• Decreased free radical generation
• Inhibition of apoptotic pathways

Eligibility Criteria

Therapeutic hypothermia should be considered for infants meeting ALL of the following criteria: [10,11,17]

Criteria A - Evidence of Perinatal Asphyxia (any of):

• Apgar score ≤5 at 10 minutes
• Continued need for resuscitation at 10 minutes
• Cord or early arterial pH less than 7.0
• Base deficit ≥16 mEq/L

Criteria B - Evidence of Moderate-Severe Encephalopathy:

• Altered level of consciousness (lethargy, stupor, coma)
• Abnormal tone (hypotonia or extensor posturing)
• Abnormal reflexes (weak/absent suck, Moro)
• Clinical seizures (may be subtle)
• Abnormal amplitude-integrated EEG (if available)

Additional Requirements:

• Gestational age ≥36 weeks
• Age ≤6 hours at initiation of cooling
• No congenital anomalies or alternative diagnoses explaining encephalopathy

Cooling Protocol

Target Temperature: 33.5°C ± 0.5°C (whole body cooling) or 34-35°C (selective head cooling)

Duration: 72 hours of therapeutic hypothermia

Method:

• Whole body cooling: Cooling blanket, servo-controlled
• Selective head cooling: Cool cap with mild systemic hypothermia

Rewarming:

• Slow rewarming over 6-12 hours (0.2-0.5°C/hour)
• Monitor for seizures during rewarming

Outcomes with Therapeutic Hypothermia

Evidence from Landmark Trials (CoolCap, NICHD, TOBY, ICE, neo.nEURO.network): [10,11,17]

• Reduction in death or major disability: NNT = 7-9
• Reduction in mortality: Absolute risk reduction ~10%
• Improvement in survival without disability: From ~40% to ~50%
• Benefits demonstrated at 18-24 month follow-up, sustained to school age

Critical Point: Time Is Brain: Therapeutic hypothermia must be initiated within 6 hours of birth for maximum benefit. If an infant meets criteria for cooling, passive cooling (turning off warmer, removing blankets) should begin immediately and the infant should be transferred urgently to a cooling center. Do NOT delay transfer for investigations.

Passive Cooling During Transport

• Turn off radiant warmer
• Remove blankets (leave diaper)
• Target rectal/esophageal temperature 33-35°C
• Monitor temperature continuously
• Avoid overcooling (less than 32°C)
• Avoid hyperthermia (worsens outcomes)

---

Special Populations

Preterm Infants (less than 32 Weeks)

Preterm infants have unique physiological vulnerabilities requiring modified resuscitation approaches:

Thermoregulation:

• Polyethylene bag/wrap without drying (except head)
• Increase ambient temperature to 23-25°C (up to 26°C for less than 28 weeks)
• Chemical thermal mattress
• Target temperature 36.5-37.5°C

Respiratory Support:

• Start with lower FiO2 (21-30%)
• T-piece resuscitator preferred for consistent PEEP
• Consider CPAP for spontaneously breathing preterm infants with respiratory distress
• Lower threshold for intubation and surfactant

Circulation:

• Delayed cord clamping (30-60 seconds if vigorous)
• Caution with volume boluses (IVH risk)

Specific Risks:

• Intraventricular hemorrhage (avoid wide BP swings, hypercarbia, hypoxia)
• Retinopathy of prematurity (avoid hyperoxia)
• Bronchopulmonary dysplasia (avoid lung injury from high pressures/volumes)

Congenital Diaphragmatic Hernia

Recognition: Scaphoid abdomen, respiratory distress, bowel sounds in chest, heart displaced

Key Modifications:

• Immediate intubation - avoid bag-mask ventilation (causes gastric distension)
• Low ventilation pressures (avoid barotrauma to hypoplastic lung)
• Insert orogastric tube for gastric decompression
• Prepare for possible ECMO
• Do NOT place infant in trendelenburg position

Airway Anomalies

Pierre-Robin Sequence: Micrognathia, glossoptosis, cleft palate

• Prone positioning may relieve obstruction
• Nasopharyngeal airway
• Early anesthesia/ENT consultation for difficult airway

Choanal Atresia: Bilateral obstruction causes severe distress

• Infants are obligate nasal breathers
• Insert oral airway; maintain open mouth

Suspected Blood Loss

Signs: Pallor, weak pulses, poor perfusion despite resuscitation, history of abruption/previa

Management:

• Urgent IV access
• Volume resuscitation: Normal saline 10 mL/kg initially
• Consider O-negative blood if significant hemorrhage suspected
• May need higher volumes (up to 30-40 mL/kg) in severe cases

---

Discontinuation of Resuscitation

When to Consider Stopping

This is one of the most difficult decisions in neonatology and should involve the entire team and, when possible, the family.

Consider Discontinuation When:

• No heart rate detected after 20 minutes of optimal resuscitation
• Gestational age or birth weight at threshold of viability without response
• Lethal congenital anomaly confirmed

Factors to Consider:

• Gestational age and presumed prognosis
• Underlying etiology (reversible vs. irreversible)
• Response to resuscitation (any heart rate present)
• Time elapsed since birth
• Quality of resuscitation efforts
• Parental wishes (prenatal counseling)
• Local resources and capabilities

Critical Point: An Apgar score of 0 at 10 minutes is associated with very high mortality (> 95%) and severe disability in survivors. However, individual cases with good outcomes have been reported, and the decision to stop should not be based solely on time. [1,18]

Communication with Family

• Involve parents as soon as feasible
• Provide honest, compassionate information
• Explain what has been done and what is being observed
• Allow parents to see/hold their baby
• Offer spiritual/cultural support
• Involve palliative care if available

---

Documentation

Required Elements

Apgar Score Documentation

Apgar scores should be assigned at 1 and 5 minutes. If 5-minute score is less than 7, continue scoring every 5 minutes until 20 minutes.

Note: Apgar scores are NOT used to guide resuscitation decisions but serve as documentation of newborn status. [1]

Quality Improvement

Performance Metrics

Team Training

• NRP certification: Recommended for all healthcare providers attending deliveries
• Simulation training: Regular practice improves team performance
• Debriefing: Post-event debriefing identifies areas for improvement
• Mock codes: Regular drills to maintain readiness

---

Key Clinical Pearls

Assessment Pearls

Clinical Pearl: Heart rate is the primary indicator of successful resuscitation. An improving heart rate indicates effective ventilation and oxygenation. Failure of heart rate to improve suggests inadequate ventilation - troubleshoot with MR SOPA before escalating.

Clinical Pearl: The majority of neonatal resuscitation is about effective ventilation. Unlike adult arrest (often cardiac arrhythmia), neonatal arrest is almost always hypoxic in origin. Establishing lung inflation breaks the hypoxia-bradycardia cycle.

Clinical Pearl: Chest rise is the best indicator of adequate ventilation, not the manometer pressure. If you see chest rise and the heart rate is improving, ventilation is effective regardless of the measured PIP.

Treatment Pearls

Clinical Pearl: Avoid routine deep suctioning - it can cause vagal bradycardia, mucosal injury, and delays initiation of ventilation. Gentle suctioning only if visible obstruction.

Clinical Pearl: Room air is appropriate for term resuscitation. The evidence shows no benefit to starting with 100% oxygen, and potential harm from oxidative stress. Titrate FiO2 to preductal SpO2 targets.

Clinical Pearl: Epinephrine is rarely needed - only 0.01-0.03% of deliveries require it. If you're reaching for epinephrine, ensure ventilation is truly effective first. Most HR less than 60 will resolve with optimized PPV.

Clinical Pearl: Delayed cord clamping benefits almost everyone - unless immediate resuscitation on the warmer is essential, wait at least 30-60 seconds. The blood volume and iron transfer have lasting benefits.

Disposition Pearls

Clinical Pearl: Think hypothermia for HIE early - if an infant has required significant resuscitation and shows signs of encephalopathy, begin passive cooling and arrange transfer within the 6-hour window for therapeutic hypothermia.

Clinical Pearl: Communicate with parents - they should be kept informed throughout and as soon as possible after resuscitation. Honest, compassionate communication helps families process these events.

Q: What is the compression-to-ventilation ratio in neonatal resuscitation? A: 3:1 (3 compressions followed by 1 ventilation), totaling 120 events per minute.

Q: What is the recommended initial FiO2 for term infant resuscitation? A: 21% (room air), titrating to preductal SpO2 targets.

Q: A term infant is born through meconium-stained fluid and is not breathing. What is the first step? A: Initial steps (warm, dry, stimulate, position). If apneic or HR less than 100, begin PPV. Do NOT delay ventilation for suctioning. Consider intubation only if airway obstruction prevents effective ventilation.

Q1: What are your immediate priorities?

• Provide warmth, position in neutral sniffing position
• Assess breathing and heart rate
• If HR less than 100 or apneic → Begin PPV immediately
• Do NOT delay resuscitation for suctioning

Q2: The heart rate is 80 bpm and there is no chest rise with PPV. What do you do?

• Apply MR SOPA corrective steps systematically
• Check mask seal, reposition airway, suction if needed, open mouth, increase pressure
• If still no chest rise → Consider intubation for tracheal suctioning if obstruction suspected

Q3: You intubate and suction thick meconium. The heart rate drops to 50 bpm. Next steps?

• Begin chest compressions (3:1 ratio with ventilation)
• Ensure effective ventilation post-suctioning
• Prepare epinephrine and UVC access
• Continue 60 seconds, reassess

Q4: What post-resuscitation concerns would you have?

• Meconium aspiration syndrome
• Hypoxic-ischemic encephalopathy (assess for cooling criteria)
• PPHN
• Respiratory support requirements

Scenario 2: Extreme Preterm Infant

Stem: You are attending a delivery at 26 weeks gestation. The mother received antenatal steroids. What preparations would you make?

Questions and Expected Answers:

Q1: What specific equipment and environmental preparations are needed?

• Polyethylene bag/wrap for thermoregulation
• Increase room temperature to 25-26°C
• T-piece resuscitator with PEEP capability
• Small ETT sizes (2.5 mm) available
• Surfactant available

Q2: The baby is born with good tone and HR 110 but has subcostal recession. How do you manage?

• Apply polyethylene wrap without drying
• Apply CPAP (5-6 cm H2O) via mask
• Apply pulse oximeter to right wrist
• Start FiO2 at 21-30%, titrate to SpO2 targets
• Delayed cord clamping if stable

Q3: What oxygen targets would you aim for?

• More gradual rise in preterm infants
• Avoid hyperoxia (risk of ROP)
• Target SpO2 85-95% by 10 minutes

• Bronchopulmonary dysplasia from lung injury

Scenario 3: Failed Resuscitation

Stem: You are resuscitating a term infant who required compressions and epinephrine. After 15 minutes, the heart rate remains undetectable.

Questions and Expected Answers:

Q1: What reversible causes should you consider?

• Hypovolemia (bleeding - give volume)
• Tension pneumothorax (decompress)
• Congenital heart disease (ductal dependent lesion)
• Severe metabolic disorder
• Congenital diaphragmatic hernia

Q2: When would you consider discontinuing resuscitation?

• No detectable heart rate after 20 minutes of optimal resuscitation
• Consider prenatal counseling, prognosis, family wishes
• Apgar 0 at 10 minutes associated with > 95% mortality/severe disability

Q3: How would you communicate with the family?

MCQ/SBA Practice Questions

Question 1

A term newborn is delivered and appears apneic with poor tone. After drying, warming, and stimulation for 30 seconds, the infant remains apneic with a heart rate of 80 bpm. What is the most appropriate next step?

A. Continue stimulation for another 30 seconds B. Administer epinephrine via endotracheal tube C. Begin positive pressure ventilation D. Perform chest compressions E. Intubate immediately

Answer: C

Explanation: PPV should be initiated when an infant remains apneic or has HR less than 100 bpm after initial steps. The heart rate is 80 (below 100), indicating the need for PPV. Chest compressions are only started if HR less than 60 after 30 seconds of effective PPV. Epinephrine is given only if HR remains less than 60 despite compressions. [1]

Question 2

During neonatal resuscitation, you have provided 30 seconds of effective PPV with visible chest rise. The heart rate is now 55 bpm. What is the correct ratio for coordinated chest compressions and ventilations?

A. 15:2 B. 30:2 C. 5:1 D. 3:1 E. Continuous compressions with asynchronous ventilation

Answer: D

Explanation: Neonatal resuscitation uses a 3:1 compression-to-ventilation ratio (90 compressions + 30 breaths per minute). This differs from pediatric (15:2) and adult (30:2) ratios because neonatal arrest is almost always due to respiratory failure, making ventilation the priority intervention. [1,15]

Question 3

A preterm infant at 28 weeks gestation is born and placed in a polyethylene bag. The infant has weak respiratory effort with HR 90 bpm. What is the recommended initial FiO2?

A. 100% B. 50% C. 40% D. 21-30% E. 21%

Answer: D

Explanation: For preterm infants less than 35 weeks, initial resuscitation should begin with 21-30% oxygen, titrated to preductal SpO2 targets. This reduces oxidative stress and risk of retinopathy of prematurity. Term infants start at 21% (room air). [1,4]

Question 4

Which of the following is an indication for therapeutic hypothermia in a newborn?

A. 35-week preterm infant with Apgar 4 at 5 minutes B. Term infant with Apgar 3 at 10 minutes and moderate encephalopathy C. Term infant with cord pH 7.15 and base deficit -10 D. 38-week infant with meconium aspiration but normal neurological exam E. Term infant requiring brief PPV but fully recovered by 5 minutes

Answer: B

Explanation: Therapeutic hypothermia requires: (1) ≥36 weeks gestation, (2) evidence of perinatal asphyxia (Apgar ≤5 at 10 min, or pH less than 7.0, or BD ≥16, or ongoing resuscitation at 10 min), AND (3) moderate-severe encephalopathy. Option B meets all criteria. The preterm infant (A) does not qualify based on gestation. [10,11,17]

Question 5

What is the recommended dose of epinephrine via the intravenous route during neonatal resuscitation?

A. 0.1-0.3 mg/kg of 1:1,000 solution B. 0.01-0.03 mg/kg of 1:10,000 solution C. 0.05-0.1 mg/kg of 1:10,000 solution D. 0.1 mg/kg of 1:1,000 solution E. 1 mg flat dose

Answer: B

Explanation: The IV/IO dose of epinephrine in neonatal resuscitation is 0.01-0.03 mg/kg of 1:10,000 solution (0.1-0.3 mL/kg). The higher dose (0.05-0.1 mg/kg) is used for the endotracheal route due to unpredictable absorption. Never use 1:1,000 concentration for neonates. [1,7]

Clinical Case Studies

Case 1: Routine Resuscitation

Presentation: A 39-week infant is born via normal vaginal delivery. At birth, the infant is blue, has weak cry, and moderate tone.

Initial Assessment:

• Place under radiant warmer
• Dry and stimulate
• Position airway (neutral sniffing)

At 30 seconds: Infant begins crying, improving tone, HR 120 bpm, acrocyanosis persisting

Management:

• Continue observation
• Apply pulse oximeter to right wrist
• Skin-to-skin with mother when stable
• Routine newborn care

Apgar Scores: 1 min: 6, 5 min: 9

Teaching Points:

• Most newborns need only warmth, drying, and stimulation
• Central cyanosis resolves over first 5-10 minutes
• Acrocyanosis (blue hands/feet) is normal and not an indication for intervention

Case 2: Requires PPV and Intubation

Presentation: A 41-week infant is delivered by emergency cesarean for fetal bradycardia. At birth, the infant is pale, floppy, and apneic.

Initial Assessment:

• Place under warmer, dry, stimulate
• Position airway
• No response to stimulation

At 30 seconds: Apneic, HR 70 bpm

Management:

• Begin PPV with room air at 40-60 breaths/min
• Apply pulse oximeter
• No chest rise initially → MR SOPA steps
• Reposition, increase pressure → now chest rise present

At 60 seconds: HR 50 bpm despite chest rise

Escalation:

• Begin chest compressions 3:1 ratio
• Intubate for coordinated CPR
• Continue compressions + ventilation

At 2 minutes: HR 45 bpm

Further Management:

• Administer epinephrine 0.02 mg/kg IV via UVC
• Continue compressions
• Consider volume if hypovolemia suspected

At 3 minutes post-epinephrine: HR 100 bpm, compressions stopped

Post-Resuscitation:

• Continue ventilation, assess for spontaneous breathing
• Check blood gas, glucose
• Assess for encephalopathy → meets cooling criteria
• Begin passive cooling, arrange transfer

Apgar Scores: 1 min: 1, 5 min: 3, 10 min: 5

Teaching Points:

• Escalation follows algorithm systematically
• Ensure ventilation is effective before adding compressions
• Epinephrine rarely needed but critical when indicated
• Early identification of HIE candidates for cooling
