Newborn Resuscitation
Key Points
- The primary priority in neonatal resuscitation is establishing effective ventilation.
- Temperature control (36.5 C to 37.5 C target) is tightly linked to respiratory and metabolic outcomes.
- Positive-pressure ventilation is initiated when spontaneous breathing is absent or ineffective and heart rate remains low.
- Escalation pathways include CPAP, intubation/mechanical ventilation, and advanced therapies when hypoxemia persists.
Pathophysiology
Newborn cardiac compromise generally follows respiratory failure, so delayed ventilation rapidly worsens oxygenation and perfusion. Effective lung inflation is the pivotal intervention that improves heart rate and stabilizes transition.
Hypothermia increases glucose consumption, acidosis risk, and respiratory instability. Resuscitation therefore requires simultaneous respiratory support and thermal protection.
Classification
- Initial supportive transition: Drying, stimulation, airway positioning/clearing, thermal support.
- Basic ventilatory support: Positive-pressure ventilation and oxygen titration.
- Advanced respiratory support: CPAP, intubation, conventional or high-frequency ventilation.
- Rescue-level support: Inhaled nitric oxide and ECMO for refractory cardiopulmonary failure in eligible infants.
Nursing Assessment
NCLEX Focus
Priority questions test when to escalate from routine transition support to active resuscitation.
- Assess breathing/crying effort, tone, and heart rate immediately after birth.
- Trend oxygen saturation and work of breathing during and after interventions.
- Monitor for signs of persistent hypoxemia, bradycardia, or respiratory fatigue.
- Monitor thermal status continuously and correct hypothermia rapidly.
- Reassess response after each intervention step to guide escalation/de-escalation.
Nursing Interventions
- Initiate airway positioning, drying, stimulation, and warmth without delay.
- Start positive-pressure ventilation at protocol rate when indicated and monitor heart-rate response.
- Titrate oxygen carefully to saturation targets and avoid unnecessary hyperoxia.
- Prepare/assist with intubation and surfactant delivery when respiratory failure persists.
- Coordinate multidisciplinary escalation for nitric oxide or ECMO candidacy in refractory cases.
Ventilation Delay
Delayed initiation of effective ventilation significantly increases risk of severe morbidity and death in compromised newborns.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| surfactants | Beractant (Survanta) context | Used in surfactant-deficient lungs; monitor for desaturation, bradycardia, and hemodynamic changes. |
| inhaled-nitric-oxide | iNO context | Pulmonary vasodilation support for selected severe hypoxemia/pulmonary hypertension pathways. |
| oxygen-therapy | Supplemental oxygen context | Deliver humidified/warmed oxygen with close saturation monitoring and titration. |
Clinical Judgment Application
Clinical Scenario
A newborn at 1 minute remains apneic with poor tone and heart rate under 100 bpm despite stimulation and airway repositioning.
Recognize Cues: Persistent apnea and bradycardia indicate failed spontaneous transition. Analyze Cues: Ventilatory failure is primary cause of ongoing instability. Prioritize Hypotheses: Immediate priority is effective ventilation and thermal stabilization. Generate Solutions: Begin PPV, apply monitoring, reassess heart rate, and escalate respiratory support if inadequate response. Take Action: Implement protocolized resuscitation sequence and call neonatal team support. Evaluate Outcomes: Heart rate rises and respiratory effort improves, or advanced support pathway is activated.
