5.1 Immediate Neonatal Assessment, APGAR Scoring & Resuscitation

5.1 Immediate Neonatal Assessment, Apgar & NRP 9th Edition

The 2025 AHA/AAP neonatal resuscitation guidance is reflected in NRP 9th Edition. The central principle is simple: establish effective ventilation promptly. Heart-rate response—not color or Apgar—determines escalation.

Preparation, Cord Management & Initial Assessment

Before every birth, complete a team briefing: gestational age, maternal/fetal risks, cord plan, equipment check, role assignment, anticipated escalation, and who will document. At least one person whose sole responsibility is the newborn must be able to perform initial steps and PPV; additional skilled personnel attend when risk is higher.

For most term and preterm newborns who do not require immediate resuscitation, defer cord clamping for at least 60 seconds while maintaining warmth and assessing transition. The cord plan changes when placental circulation is interrupted or immediate care cannot be provided safely with the cord intact.

At birth ask:

1. Is the newborn term?
2. Is tone good?
3. Is the newborn breathing or crying?

A newborn meeting all three remains skin-to-skin for warmth, drying as needed, airway positioning, and ongoing observation. If any answer is no, move to a warm environment, position the airway, dry and stimulate, and clear secretions only when obstruction is suspected. Routine suction can cause delay, bradycardia, and trauma.

Apgar Scoring

Apgar assigns 0, 1, or 2 points for Appearance, Pulse, Grimace, Activity, and Respiration at 1 and 5 minutes. If the 5-minute score is below 7, repeat every 5 minutes through 20 minutes while continuing care.

Never wait for the 1-minute score to start ventilation. Apgar describes the newborn at a point in time and response to care; it does not diagnose asphyxia by itself.

PPV: The Priority Intervention

Begin positive-pressure ventilation within the first minute when the newborn is apneic or gasping or the heart rate is below 100/min after initial steps. Use a cardiac monitor when resuscitation is underway and pulse oximetry when PPV or supplemental oxygen is used; place the saturation probe preductally on the right hand or wrist.

Initial oxygen concentration:

• 35 weeks or more: 21%
• 32 through 34+6 weeks: 21% to 30%
• Below 32 weeks: 30% to 100%

Titrate blended oxygen to the newborn's response and current preductal targets. Under the 2025 algorithm, displayed targets begin at 2 minutes because the cord is commonly left intact for at least 60 seconds:

Ventilate at 40 to 60 inflations/min and look for visible chest movement and a rising heart rate. If the heart rate is not rising and the chest is not moving, correct ventilation: adjust the mask, reposition the airway, suction only if obstructed, open the mouth, increase pressure gradually until chest movement occurs, and place an endotracheal tube or laryngeal mask when needed. The familiar MR SOPA sequence is a memory aid; reassessment after each step matters more than reciting it.

If the heart rate is 60 to 99, continue effective PPV and corrective steps. If it reaches at least 100 with spontaneous breathing, wean support according to respirations, oxygenation, and clinical condition.

Chest Compressions & Medication

Start compressions only when the heart rate remains below 60 after at least 30 seconds of ventilation that moves the chest, preferably through an alternative airway. Use the two-thumb encircling technique on the lower third of the sternum, depress about one-third of the chest depth, coordinate 3 compressions to 1 ventilation, and use 100% oxygen. Reassess after 60 seconds of coordinated compressions and ventilation.

If heart rate remains below 60:

• Give intravascular epinephrine 0.01 to 0.03 mg/kg of 0.1 mg/mL solution through umbilical venous or intraosseous access. Flush according to the current NRP route-specific protocol and repeat every 3 to 5 minutes as indicated.
• While vascular access is being obtained, endotracheal epinephrine 0.05 to 0.1 mg/kg may be used, but vascular dosing is preferred because absorption through the tube is less reliable.
• If blood loss or hypovolemia is suspected and heart rate remains below 60 despite effective ventilation, compressions, and epinephrine, give normal saline or blood 10 to 20 mL/kg using the current resuscitation order and reassess. Pallor, weak pulses, poor perfusion, abruption, vasa previa, cord disruption, or fetomaternal hemorrhage increase concern.

After resuscitation, prevent hypothermia, monitor glucose, oxygenation, ventilation, perfusion, neurologic status, and recurrence of apnea or bradycardia, and arrange the appropriate level of neonatal care and family communication.
