# Neonatal Resuscitation and Delivery Room Management

## Overview

Approximately 10% of newborns require some assistance at birth, and roughly 1% need extensive resuscitation. The Neonatal Resuscitation Program (NRP) algorithm provides a standardized, evidence-based approach to delivery room management. The cornerstones of successful neonatal resuscitation are preparation, team communication, and anticipation of risk factors before the infant is delivered.

## Antenatal Risk Assessment

Effective delivery room management begins before birth with a thorough review of the maternal history. Key factors include gestational age, prenatal ultrasound findings, and maternal comorbidities such as diabetes, preeclampsia, and chorioamnionitis. High-risk deliveries requiring full team preparation include preterm birth before 35 weeks, multiple gestations, known congenital anomalies (particularly congenital diaphragmatic hernia and airway masses), non-reassuring fetal heart tracing, meconium-stained amniotic fluid, and prolonged rupture of membranes. When these risk factors are identified, a full resuscitation team should be assembled and equipment checked before delivery.

## NRP Algorithm (8th Edition Updates)

### Initial Steps (within 30 seconds)

The initial steps of neonatal resuscitation focus on warmth, stimulation, and assessment. The infant is placed on a radiant warmer, with plastic wrap and an exothermic mattress added for infants less than 32 weeks gestation. The infant is dried and stimulated by back rubbing or flicking the soles. The airway is positioned in a neutral "sniffing" position, with suctioning performed only if the airway appears obstructed. The provider then assesses tone, breathing effort, and heart rate.

### Positive Pressure Ventilation (PPV)

PPV is indicated if the infant is apneic, gasping, or has a heart rate below 100 beats per minute after initial steps are completed. Ventilation begins with room air (21% FiO2) for term infants or 21-30% for preterm infants. A T-piece resuscitator is preferred because it provides consistent peak inspiratory pressure and PEEP delivery. The ventilation rate is 40-60 breaths per minute. Chest rise is assessed with each breath, and if it is inadequate, the MR SOPA corrective steps are followed in sequence: Mask adjustment to improve seal, Repositioning the airway, Suctioning the mouth and nose, Opening the mouth, increasing Pressure, and finally considering an Alternative airway (laryngeal mask airway or endotracheal tube).

### Cardiac Compressions

Cardiac compressions are initiated when the heart rate remains below 60 beats per minute despite 30 seconds of effective PPV. The two-thumb encircling hands technique is preferred, providing compression on the lower third of the sternum. The compression-to-ventilation ratio is 3:1, reflecting the predominantly respiratory etiology of neonatal arrest. FiO2 is increased to 100% during compressions. The heart rate is reassessed after 60 seconds of coordinated compressions and ventilation.

### Epinephrine and Volume Expansion

If the heart rate remains below 60 bpm despite effective compressions and ventilation, epinephrine is administered. Volume expansion with 10 mL/kg of normal saline or O-negative packed red blood cells is indicated for suspected hypovolemia from conditions such as placental abruption or cord avulsion.

| Medication | Route | Dose | Notes |
|-----------|-------|------|-------|
| Epinephrine | IV (UVC preferred) | 0.01-0.03 mg/kg | Preferred route for reliable absorption |
| Epinephrine | Endotracheal | 0.05-0.1 mg/kg | Use while IV access being established |
| Normal saline | IV | 10 mL/kg | For suspected hypovolemia |
| O-negative PRBCs | IV | 10 mL/kg | For acute blood loss |

## Delayed Cord Clamping

Delayed cord clamping for at least 30-60 seconds is recommended for vigorous term and preterm infants. In preterm infants, the benefits include improved transitional circulation, higher hematocrit, and reduced risk of intraventricular hemorrhage and necrotizing enterocolitis. Intact cord milking serves as an alternative when delayed clamping is not feasible, such as when a non-vigorous infant requires immediate resuscitation at the warmer. However, cord milking remains controversial in infants less than 28 weeks due to the potential for rapid volume shifts and increased risk of intraventricular hemorrhage.

## Management of the Depressed Neonate

For the non-vigorous infant born through meconium-stained amniotic fluid, routine intubation and tracheal suctioning are no longer recommended. Instead, PPV is initiated if the infant is not breathing, and intubation is reserved for cases of airway obstruction. Therapeutic hypothermia is indicated for moderate-to-severe hypoxic-ischemic encephalopathy in infants at 36 weeks gestation or greater. It should be initiated within 6 hours of birth, targeting a core temperature of 33.5 degrees Celsius for 72 hours. Passive cooling (turning off the radiant warmer) should begin during transport to a cooling center.

## Temperature Management

Maintaining axillary temperature between 36.5 and 37.5 degrees Celsius is a fundamental goal of delivery room care. Both hypothermia and hyperthermia are associated with increased morbidity and mortality. For preterm infants less than 32 weeks, temperature protection requires polyethylene wrapping, an exothermic mattress, and a pre-warmed delivery room at 23-25 degrees Celsius.

## Oxygen Management and Monitoring

Pre-ductal SpO2 monitoring (using a sensor on the right hand) is indicated for all infants requiring resuscitation. Target oxygen saturations rise progressively during the first minutes of life:

| Time After Birth | Target SpO2 |
|-----------------|-------------|
| 1 minute | 60-65% |
| 2 minutes | 65-70% |
| 3 minutes | 70-75% |
| 4 minutes | 75-80% |
| 5 minutes | 80-85% |
| 10 minutes | 85-95%  |  FiO2 is titrated based on these targets to avoid hyperoxia, which is particularly damaging in preterm infants and associated with retinopathy of prematurity and bronchopulmonary dysplasia. |

## Post-Resuscitation Care

After resuscitation, infants require monitoring for complications including persistent pulmonary hypertension, metabolic acidosis, hypoglycemia, and end-organ injury. Blood gas analysis (both cord and infant samples) provides information about acid-base status and oxygenation. Transfer to the NICU should be considered for ongoing monitoring. Documentation of the resuscitation and a debrief with the team are essential for quality improvement and team learning.

## Ethical Considerations

Periviability counseling for deliveries at 22-25 weeks involves shared decision-making with the family. Institutional guidelines vary, and decisions should consider available survival data, the burden of long-term morbidity, and family values. When resuscitation is initiated, ongoing assessment of the infant's response guides decisions about whether to continue resuscitation or redirect to comfort care.

## Clinical Pearls

Effective ventilation is the single most important step in neonatal resuscitation, and the vast majority of newborns respond to PPV alone without requiring compressions or medications. Heart rate is the most reliable indicator of resuscitation effectiveness and should be reassessed at every decision point. Equipment should always be checked before every delivery, and the MR SOPA mnemonic guides systematic troubleshooting when ventilation is ineffective. Delayed cord clamping is not appropriate when the neonate requires immediate resuscitation at the warmer. Hypothermia prevention is a priority, especially for preterm infants, who lose heat rapidly through evaporation and have limited thermogenic capacity. Apgar scores should not guide resuscitation decisions; they are assigned retrospectively and serve as a summary of the infant's condition, not as a real-time decision tool. Post-resuscitation glucose monitoring is critical, with a target of greater than 45 mg/dL, as both hypoxia and the stress response predispose to hypoglycemia.
