Neonatal Resuscitation Program (NRP): Delivery Room Guidelines

The birth of a child requires a profound, rapid physiological transition from intrauterine to extrauterine life. Within seconds of delivery, the newborn must clear fluid from the lungs, expand the alveoli, drop pulmonary vascular resistance, clamp the umbilical venous flow, and switch to pulmonary gas exchange. Approximately 90% of newborns complete this transition without assistance. However, about 10% require some support, and 1% require intensive resuscitation.

The Neonatal Resuscitation Program (NRP), developed by the American Academy of Pediatrics (AAP) and the American Heart Association (AHA), outlines the standardized algorithmic response for managing neonates who experience failure of transition at birth. Adherence to the NRP algorithm, particularly within the "Golden Minute," directly impacts neurological survival.

1. The First Steps (0 – 30 Seconds)

Resuscitation preparedness is mandatory for every delivery. At birth, the clinician must ask three initial questions:

• Is the infant term?
• Does the infant have good muscle tone?
• Is the infant breathing or crying?

If the answer to all three is yes, the newborn remains with the mother for routine care (warming, drying, positioning the airway, ongoing evaluation).

If the answer to any question is no, the infant must be moved to the radiant warmer to receive initial stabilization:

1. Warm: Maintain body temperature between 36.5В°C and 37.5В°C under the radiant warmer.
2. Position & Clear Airway: Position the head in a slight extension ("sniffing position") to open the airway. Suction the mouth then the nose if secretions obstruct breathing.
3. Dry & Stimulate: Dry the infant to prevent evaporative heat loss. Gently rub the back or flick the soles of the feet to stimulate spontaneous respiration.

2. Positive Pressure Ventilation (The Golden Minute)

Within the first **60 seconds** of life, if the infant remains **apneic, gasping, or has a heart rate <100 bpm**, Positive Pressure Ventilation (PPV) must be initiated immediately.

• Ventilation Rate: 40 to 60 breaths per minute ("Breathe, two, three, breathe, two, three").
• Initial Pressure: PIP (Peak Inspiratory Pressure) of 20–25 cm H2O, PEEP (Positive End-Expiratory Pressure) of 5 cm H2O.
• Oxygen Blending: Start at 21% FiO2 for term infants (≥35 weeks), and 21%–30% FiO2 for preterm infants (<35 weeks). Do not use 100% O2 initially to prevent oxygen free-radical tissue damage.

The Ventilation Check (MR. SOPA)

If the heart rate remains <100 bpm and chest movement is inadequate during PPV, perform the MR. SOPA troubleshooting steps sequentially:

Step	Action	Clinical Practice
M	Mask Adjustment	Reapply the mask, ensure a tight seal on the face.
R	Reposition Airway	Re-establish the sniffing position; extend the neck slightly.
S	Suction Airway	Suction the mouth and nose using a bulb syringe or suction catheter.
O	Open Mouth	Open the infant's mouth slightly and reapply mask.
P	Pressure Increase	Increase pressure in increments of 5 cm H2O (Max 40 cm H2O).
A	Alternative Airway	Perform endotracheal intubation or place a laryngeal mask (LMA).

3. Target Post-Ductal Oxygen Saturations

Newborns do not achieve normal adult oxygen saturation values immediately. Oxygen therapy should be adjusted using a pulse oximeter placed on the **right hand or wrist** (post-ductal saturation) matching these target ranges:

Time Post-Birth	Target SpO2 Range
1 Minute	60% – 65%
2 Minutes	65% – 70%
3 Minutes	70% – 75%
4 Minutes	75% – 80%
5 Minutes	80% – 85%
10 Minutes	85% – 95%

4. Advanced Resuscitation (Heart Rate <60 bpm)

If the heart rate is **<60 bpm** after at least 30 seconds of effective PPV (causing chest movement, ideally via ETT):

• Chest Compressions: Initiate compressions at a 3:1 ratio (90 compressions and 30 ventilations per minute, yielding 120 total events). Use the two-thumb technique on the lower third of the sternum. Increase FiO2 to 100%.
• Epinephrine: If HR remains <60 bpm despite compressions:
  • IV/IO Dose: 0.01 to 0.03 mg/kg of the 0.1 mg/mL (1:10,000) concentration.
  • Endotracheal (ET) Dose: 0.05 to 0.1 mg/kg if venous access is not yet established.
• Volume Expansion: Administer 10 mL/kg of Normal Saline or O-negative blood over 5-10 minutes if blood loss is suspected.
