Summary

Despite improved neonatal care, very preterm infants face high rates of neurodevelopmental handicap. Continued research into obstetric and neonatal interventions is crucial for better long-term outcomes in high-risk infants.

Background:

Long-term outlook for very preterm infants has improved significantly with advancements in obstetric and neonatal care since the 1950s.
However, neurodevelopmental handicap rates in these infants remain unacceptably high compared to term infants.
Infants experiencing Intrauterine Growth Restriction (IUGR), especially severe cases, do not reach their full intellectual potential.

Purpose of the Study:

To highlight the persistent issue of high neurodevelopmental handicap rates in very preterm infants.
To emphasize the need for continued research and testing of obstetric and neonatal care modifications.
To investigate the impact of IUGR on intellectual development and identify necessary interventions.

Main Methods:

Review of existing data on preterm infant outcomes and neurodevelopmental handicaps.
Analysis of the impact of supportive obstetric and intensive neonatal care.
Identification of potential insults (hypoxic, traumatic, biochemical) affecting preterm infants and those with IUGR.

Main Results:

While overall outlook has improved, neurodevelopmental handicap rates in very preterm infants persist at high levels.
Severe IUGR is associated with impaired intellectual potential.
Specific neonatal complications like hypoxia, hypothermia, hypoglycemia, polycythemia, and hyperbilirubinemia contribute to handicap.

Conclusions:

Further modifications in obstetric and neonatal care are essential to reduce neurodevelopmental handicaps in preterm infants.
Fundamental research is needed to understand preterm labor mechanisms for improved prevention and treatment.
Identifying and managing neonatal complications in IUGR infants is critical to mitigate handicap. Further research is required to understand IUGR's specific impact on intellectual development.
