Neonatal ventilatory techniques - which are best for infants born at term?

Area of Science:

• Neonatal Medicine
• Pediatric Pulmonology
• Critical Care

Background:

• Limited research exists on ventilatory modes specifically for term-born infants.
• Various ventilation strategies have shown mixed or short-term benefits.

Purpose of the Study:

• To review current evidence on different ventilatory modes in term-born infants.
• To identify optimal ventilation strategies and areas for future research.

Main Methods:

• Review of existing studies on ventilatory modes in term infants.
• Analysis of outcomes associated with different ventilation types, including SIMV, IMV, HFOV, and NO therapy.
• Evaluation of extracorporeal membrane oxygenation (ECMO) in severe respiratory failure.

Main Results:

• Synchronous intermittent mandatory ventilation (SIMV) may reduce ventilation duration compared to intermittent mandatory ventilation (IMV).
• High-frequency oscillatory ventilation (HFOV) benefits were not consistently confirmed in randomized trials.
• Nitric oxide (NO) may reduce mortality and ECMO need in term infants, excluding those with congenital diaphragmatic hernia (CDH).
• ECMO reduced mortality and long-term disability in severe refractory hypoxemic respiratory failure, except in CDH cases.

Conclusions:

• Optimal ventilation strategies for term-born infants require further investigation.
• Randomized trials focusing on long-term outcomes are essential to guide clinical practice.
• Specific treatments like NO and ECMO show promise in select cases but require careful consideration.
