[Development and fate of premature infants--then and now]
Insights
Advances in technology enable survival for premature infants with very low birth weight. Historical context reveals evolving survival rates and persistent challenges in reducing serious sequelae for these vulnerable infants.
Area of Science:
- Neonatal care
- Pediatric intensive care
- Perinatal medicine
Context:
- Modern technology improves survival rates for very low birth weight infants.
- Historical analysis of neonatal intensive care programs is crucial for evaluating current effectiveness.
- Early 20th-century work by A. Ylppö laid groundwork for low birth weight infant survival.
Purpose:
- To provide historical perspective on the survival and outcomes of low birth weight infants.
- To discuss the evolution of intensive care for premature infants.
- To highlight the ongoing challenges in reducing morbidity in surviving premature infants.
Summary:
- Survival rates for premature infants have improved due to technological advancements.
- Post-WWII therapeutic innovations initially worsened outcomes, but improvements in the 1960s reduced serious sequelae.
- While mortality has decreased, the rate of severe long-term health issues in surviving premature infants has remained stable for 15 years.
Impact:
- Informs current discussions on the effectiveness and efficiency of neonatal intensive care.
- Emphasizes the need for continued research and technological innovation to reduce long-term morbidity.
- Provides a historical framework for understanding progress and persistent challenges in neonatal survival and outcomes.
Abstract:
New scientific results and progress in technology allow even premature infants with very low birth weight to survive today. A vehement discussion arouse about effectiveness and efficiency of intensive care programs for these infants. However, an appreciation of the results at present should not be made without taking note of those achieved in former decades. A. Ylppö was the first pediatrician in Germany at the beginning of the 20th century, who was working systematically for the survival of low birth weight infants. He achieved remarkable results even at that time. After World War II the chances for survival of low birth weight infants became worse because of dangerous therapeutic innovations. In the 60's the frequency of serious sequelae could be reduced by improved therapeutic approaches. Since then the mortality rate is decreasing, whereas the frequency of serious sequelae remains nearly stable during the last 15 years. We hope that clinical research and new technologies may also reduce the morbidity of surviving premature babies in the future.
