Closed-loop automated oxygen control in preterm ventilated infants: a randomised controlled trial.

Area of Science:

• Neonatal Medicine
• Respiratory Care
• Medical Technology

Background:

• Preterm infants often require mechanical ventilation and supplemental oxygen.
• Maintaining optimal oxygen saturation is critical but challenging in this population.
• Current manual oxygen control methods may lead to suboptimal oxygenation.

Purpose of the Study:

• To compare the duration of mechanical ventilation in preterm infants managed with closed-loop automated oxygen control (CLAC) versus manual oxygen control.
• To evaluate the impact of CLAC on oxygenation targets and respiratory outcomes.

Main Methods:

• Randomized controlled trial conducted in a tertiary neonatal unit.
• 69 preterm infants (median gestational age 27.0 weeks) were randomized to CLAC or manual oxygen control.
• Primary outcome measure was the duration of mechanical ventilation.

Main Results:

• CLAC group experienced significantly shorter mechanical ventilation duration (11 vs 40 days) and supplemental oxygen duration (33 vs 47 days).
• Incidence of bronchopulmonary dysplasia (BPD) was lower in the CLAC group (55% vs 83.9%).
• CLAC improved time spent within target oxygen saturation range (91%-95%) and reduced hypoxemia and hyperoxemia.

Conclusions:

• CLAC use in preterm infants is associated with better oxygen saturation control.
• CLAC led to shorter durations of mechanical ventilation and supplemental oxygen, and reduced BPD incidence.
• Larger multicenter studies are needed to confirm findings before widespread clinical adoption.
