Evidence-based resuscitation techniques for the compromised neonate: a guide for NICU teams

Recent trends

Institutional resuscitation protocols are increasingly integrating delayed cord clamping for uncompromised infants while refining approaches for the depressed neonate. Teams now prioritize ventilation-first strategies, with target oxygen titration guided by pulse oximetry rather than routine free-flow oxygen. Simulation-based training is becoming standard to reinforce team roles and communication during high-stakes resuscitations.

• Shift toward less invasive ventilation, such as sustained inflations, though definitive mortality benefits remain under investigation.
• Renewed emphasis on maintaining normothermia from the point of delivery, with use of polyethylene wraps and radiant warmers for very low birth weight infants.
• Growing adoption of video laryngoscopy for training and difficult airway scenarios, despite limited long-term outcome data.

Background

Neonatal resuscitation has evolved from largely anecdotal practices to structured, evidence-driven algorithms. The Neonatal Resuscitation Program (NRP) and equivalent international guidelines provide a stepped framework: assess tone and breathing, provide warming and stimulation, then move to positive-pressure ventilation, chest compressions, and medications as needed. The underpinning principle is that the majority of compromised neonates improve with effective ventilation, making airway management the priority over early compressions or epinephrine. Robust studies on oxygen use have refined the acceptable range of initial FiO₂ to avoid hyperoxia injury in term and near-term infants. Hypothermia therapy remains standard for moderate-to-severe hypoxic-ischemic encephalopathy.

User concerns

NICU teams face several practical challenges when applying these techniques. Uncertainty about the optimal duration and pressure of sustained inflations for extremely preterm infants; consensus is partial. Difficulty in distinguishing central cyanosis from acrocyanosis in low-light conditions. Disagreements within teams over when to escalate from mask ventilation to intubation, especially when saturations improve slowly. The risk of oxygen toxicity versus hypoxia during the first few minutes. Additionally, achieving consistent chest compression-to-ventilation ratios during two-thumb compression is a frequent training gap. Finally, limited access to high-fidelity simulation equipment can hinder rehearsal of rare but critical events.

Likely impact

Formal adoption of structured, team-delineated resuscitation algorithms is expected to reduce variation in care across centers. As more units implement standardized debriefing after each resuscitation, opportunities for process improvement will multiply. Focused training on the transition from delayed cord clamping to immediate resuscitation in the preterm infant may reduce blood transfusion needs. Wider use of non-invasive carbon dioxide monitoring should lower rates of hypocarbia and hypercarbia during manual ventilation. Ongoing large-scale trials comparing 2:1 to 3:1 compression-to-ventilation ratios may shift future protocol details. In low-resource settings, simplified bag-mask training and task-shifting are likely to improve timeliness of basic resuscitation, potentially lowering early neonatal mortality.

What to watch next

• Results from randomized controlled trials assessing sustained lung inflation in extremely preterm infants and their effect on bronchopulmonary dysplasia rates.
• Integration of real-time feedback devices for ventilation parameters (tidal volume, rate, leak) into standard resuscitation.
• Clarification of optimal oxygenation targets during the first ten minutes for infants born below 32 weeks gestation.
• Expansion of telemedicine support during neonatal transports to improve adherence to resuscitation guidelines en route.
• Development of standardized team communication tools (e.g., closed-loop checklists) tailored to neonatal code settings.
