Delivery room management for extremely low birth weight infants has evolved, with strategies in 2011 aligning more closely with current guidelines than in 1997. Key changes include adjusted oxygen and pressure levels, and altered intubation criteria for these vulnerable newborns.
Area of Science:
- Neonatalogy
- Pediatric Intensive Care
- Perinatal Medicine
Background:
- Guidelines for extremely low birth weight (ELBW) infant delivery room management have advanced significantly over two decades.
- Local treatment practices and their alignment with current recommendations remained unclear.
Purpose of the Study:
- To assess changes in delivery room management strategies for ELBW infants between 1997 and 2011.
- To determine if these strategies reflect current clinical recommendations.
Main Methods:
- A questionnaire survey of neonatal intensive care units (NICUs) in Germany (1997) and Germany, Austria, Switzerland (2011).
- Comparison of delivery room management practices between the two survey periods.
- Analysis of treatment strategies including oxygenation, ventilation pressures, intubation criteria, and surfactant administration.
Main Results:
- Response rates were consistent across both surveys (63.6% in 1997, 66.2% in 2011).
- Significant changes observed by 2011 included lower initial fraction of inspired oxygen (FiO2) and peak inspiratory pressure (PiP).
- Apnea duration tolerance increased, apnea became less of a sole intubation criterion, and surfactant was used at lower FiO2 levels.
Conclusions:
- Delivery room management for ELBW infants underwent significant evolution between 1997 and 2011.
- The observed changes in treatment strategies largely align with current evidence-based recommendations.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
