Premature infants born at <25 weeks of gestation may be compromised by currently recommended resuscitation techniques

Area of Science:

• Neonatal Resuscitation
• Perinatal Medicine
• Pediatric Critical Care

Background:

• Standard resuscitation guidelines often lack specific data for extremely preterm infants.
• Delivery room management of preterm infants (<29 weeks) requires tailored approaches.
• Evaluating existing protocols in this vulnerable population is crucial.

Purpose of the Study:

• To assess the effectiveness of a standard delivery room resuscitation protocol in preterm infants born at <29 weeks gestational age.
• To compare resuscitation outcomes across different gestational age subgroups.
• To identify potential limitations of current protocols for borderline viable infants.

Main Methods:

• Observational study utilizing prospectively collected video recordings of 73 preterm infants.
• Comparison of bradycardia rates, time to target oxygen saturation, and intervention extent.
• Stratification into three gestational age groups: 22-24, 25-26, and 27-28 weeks.

Main Results:

• Infants born <25 weeks showed poorer response to resuscitation, with longer times to reach target oxygen saturation.
• This group required significantly more interventions and experienced higher rates of mortality and severe intraventricular hemorrhage.
• Lower heart rate and oxygen saturation correlated with intraventricular hemorrhage.

Conclusions:

• Current resuscitation recommendations may be inadequate for extremely preterm infants at the borderline of viability.
• These infants face increased mortality and morbidity due to challenges in achieving timely lung aeration.
• Alternative strategies like sustained inflation and delayed cord clamping warrant further investigation.
