I now have comprehensive information from multiple authoritative textbooks. Here is a complete 10-mark exam answer on Neonatal Resuscitation:

Neonatal Resuscitation

Introduction

Approximately 10% of newborns require some assistance to begin breathing at birth, and about 1% need extensive resuscitative measures. The Neonatal Resuscitation Program (NRP), jointly developed by the American Heart Association (AHA) and American Academy of Pediatrics (AAP), provides the standard framework for managing newborns at birth.

Pre-delivery Preparation

Before every delivery, a brief team briefing and equipment check is mandatory. Essential equipment includes:

Radiant warmer (pre-heated), warm blankets, hat
Self-inflating bag (450 mL) and flow-inflating bag with appropriately sized masks
Laryngoscope with straight blades (sizes 00, 0, 1)
Endotracheal tubes (ETT) - uncuffed, sizes 2.5, 3.0, 3.5, 4.0 mm
Suction device, bulb syringe, suction catheters (5, 8, 10 Fr)
Pulse oximeter and ECG leads
Epinephrine (1:10,000), normal saline
Umbilical venous catheter (3.5 Fr, 5 Fr)
Polyethylene bags for infants <29 weeks gestation

NRP Algorithm (Timed Sequence)

Initial Assessment at Birth (First 30 Seconds - "The Golden Minute")

Three questions are asked immediately:

Is the baby term gestation?
Does the baby have good tone?
Is the baby breathing or crying?

If YES to all three → routine care (skin-to-skin with mother, warmth, airway positioning, drying, ongoing evaluation).

If NO to any → place under radiant warmer and proceed with initial steps:

Warm - radiant warmer, prewarmed blankets
Position airway - "sniffing" position (slight neck extension, towel under shoulders)
Clear secretions - only if visible obstruction; suction mouth first, then nose (routine suctioning is no longer recommended)
Dry and stimulate - rub the back 2-3 times; if no response, flick soles of feet
Assess - respiratory effort and heart rate

Ongoing Resuscitation (30-60 Seconds)

After warming, drying, stimulation - reassess:

If HR >100 bpm but labored breathing or persistent cyanosis:

Open airway, suction if obstruction visible
Apply pulse oximetry to right wrist/hand (preductal)
Supplemental O2 to reach targeted SpO2
Consider CPAP

If apneic, gasping, or HR <100 bpm:

Begin Positive Pressure Ventilation (PPV)
Attach SpO2 monitor; consider ECG monitor
Start with room air (21% O2) in term infants (avoid hyperoxia)
Rate: 40-60 breaths/min
Peak inspiratory pressure: 20 cm H2O (initial breaths may need 30 cm H2O to clear lung fluid)
Assess chest rise as marker of adequacy

Targeted Preductal SpO2 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%

Advanced Resuscitation (>60-90 Seconds) - HR <100 bpm Despite PPV

Check and correct ventilation (MR SOPA):

Mask adjustment
Reposition airway
Suction
Open mouth
Pressure increase
Airway alternative (ETT or laryngeal mask)

ETT size by gestational age:

<30 weeks: 2.5 mm
30-34 weeks: 3.0 mm
≥35 weeks: 3.5 mm
Depth (cm) = weight (kg) + 6

Chest Compressions - HR <60 bpm Despite Adequate Ventilation for 30 Seconds

Technique: Two-thumb encircling method (preferred) or two-finger method
Location: Lower one-third of sternum
Depth: One-third of anteroposterior chest diameter
Ratio: 3 compressions : 1 breath = 90 compressions + 30 breaths per minute
Compressions and ventilations must NOT be simultaneous
If not already done, intubate and switch to 100% O2
Establish emergency umbilical venous catheter (UVC) access
Stop compressions when HR >60 bpm

Medications - HR <60 bpm Despite Compressions + Adequate Ventilation (45-60 Seconds)

Epinephrine (drug of choice):

IV/IO: 0.01-0.03 mg/kg (0.1-0.3 mL/kg of 1:10,000 solution)
Intratracheal (if no IV access): 0.05-0.1 mg/kg (0.5-1 mL/kg of 1:10,000 solution)
Route: Umbilical venous catheter is preferred; IO if UVC not possible

Volume expansion (if hypovolemia suspected - pallor, poor perfusion, weak pulses):

Normal saline 0.9% - 10 mL/kg IV over 5-10 minutes
Or O-negative blood 10 mL/kg
Give slowly in preterm infants (risk of IVH)

Drugs no longer recommended:

Naloxone - not recommended for respiratory depression; contraindicated if maternal opioid addiction (risk of neonatal seizures)
Sodium bicarbonate - not recommended routinely (worsens intracellular acidosis)

APGAR Score

Assessed at 1, 5, and 10 minutes:

Sign	0	1	2
Heart rate	Absent	<100 bpm	≥100 bpm
Respirations	Absent	Slow, irregular	Good, crying
Muscle tone	Limp	Some flexion	Active, good flexion
Reflex irritability	No response	Grimace	Cough/sneeze
Color	Blue/pale	Pink body, blue extremities	Completely pink

1-minute score: assesses need for resuscitation
5-minute score: assesses efficacy of resuscitation
Score <7 at 5 min: repeat every 5 minutes until ≥7

Special Situations

Meconium-stained amniotic fluid:

Routine intrapartum oropharyngeal/nasopharyngeal suctioning is NOT recommended (even for thick meconium)
Tracheal suctioning is also NOT recommended for vigorous infants
Only if poor tone, poor respiratory effort, or HR <100 bpm after 1 min of PPV - consider tracheal suctioning

Preterm infants (<29 weeks):

Wrap in polyethylene bag (plastic wrap) to prevent hypothermia
No cord milking in <28 weeks (risk of IVH)
Delayed cord clamping (30-60 seconds) for vigorous term and preterm infants

Delayed cord clamping:

Recommended for at least 30-60 seconds for vigorous term and preterm infants
Improves iron stores, blood volume, reduces need for transfusion

Post-resuscitation Care

Transfer to NICU for monitoring
Therapeutic hypothermia (cooling to 33.5°C for 72 hours) for term/near-term (≥36 weeks) newborns with moderate-to-severe hypoxic-ischemic encephalopathy (HIE) - reduces mortality and improves neurological outcomes
Monitor for hypoglycemia (associated with adverse outcomes in birth asphyxia)
Avoid hyperglycemia as well

When to Discontinue Resuscitation

If no signs of life (no heartbeat, no breathing) after 10 minutes of complete, adequate resuscitative efforts, it is appropriate to consider stopping resuscitation. Counseling should be done with the family.
