Perinatal management and outcome in the infant weighing 1,000 to 2,000 grams
Insights
Reducing neonatal mortality in infants under 1,500 grams is crucial. An active obstetric approach combined with neonatal intensive care significantly improved survival rates for both low birth weight and larger infants.
Area of Science:
- Obstetrics and Neonatology
- Perinatal Medicine
- Neonatal Intensive Care
Background:
- Neonatal mortality in infants weighing less than 1,500 grams remains a significant challenge in obstetrics.
- A substantial number of births involve infants with low birth weight (1,000-1,500 grams) and very low birth weight (1,501-2,000 grams).
Purpose of the Study:
- To evaluate the impact of an active obstetric approach and immediate neonatal intensive care on neonatal mortality and morbidity.
- To improve survival rates for infants weighing less than 1,500 grams and manage morbidity in infants weighing 1,501-2,000 grams.
Main Methods:
- Retrospective analysis of live births between January 1, 1976, and December 31, 1978, in a Perinatal Unit.
- Categorization of infants based on birth weight: 1,000-1,500 grams and 1,501-2,000 grams.
- Assessment of outcomes following the implementation of an active obstetric strategy and neonatal intensive care.
Main Results:
- Immediate neonatal intensive care effectively managed morbidity and prevented deaths in infants weighing 1,501-2,000 grams.
- A more active obstetric approach positively impacted both mortality in infants under 1,500 grams and morbidity in the heavier group.
- A corrected survival rate of 100% was achieved in both weight groups during 1978.
Conclusions:
- An active obstetric approach is vital for improving neonatal outcomes, particularly for low birth weight infants.
- The combination of proactive obstetrics and prompt neonatal intensive care can significantly reduce neonatal mortality and morbidity.
- The study demonstrates the successful implementation of strategies leading to 100% survival in targeted neonatal populations.
Abstract:
Accomplishing reduction of the neonatal mortality rate in the infant weighing less than 1,500 grams accounts for one of the major areas of potential impact in obstretrics today. Of the 8,169 live births occurring in the Perinatal Unit, Women's College Hospital, between January 1, 1976, and December 31, 1978, 79 infants weighed between 1,000 and 1,500 grams and 135 were between 1,501 and 2,000 grams. Analysis of approach and outcome shows that with immediate neonatal intensive care, morbidity in the larger group can be managed to prevent death. The mortality rate in the infant weighing less than 1,500 grams, as well as morbidity in the larger group, is improved by a more active obstetric approach for the sake of the neonate. In this study, such an approach resulted in a corrected survival rate of 100% in both groups during 1978.
