Management of extremely low-birth-weight infants.

ABSTRACT

Better health care of women during pregnancy and delivery, improvement in neonatal intensive therapy and technology have led to a decrease in neonatal mortality and morbidity and to lower limits of birth weight and gestational age for survival. This paper refers to the management protocol used in the Department of Perinatal Pathology of the Provincial Maternity Hospital of Milan for extremely low-birth-weight (ELBW) infants (birth weight < 1000 g). In this hospital, all newborn infants presenting evidence of life, irrespective of birth weight and gestational age, are resuscitated and transferred to the Neonatal Intensive Care Unit (NICU) for clinical management. After the introduction of this protocol the mortality rate of ELBW infants dropped from 71.4% in 1977-78 to 48% in 1987-88. In a group of 72 ELBW infants with a mean birth weight of 850 g and a mean gestational age of 27 weeks, 80% presented a normal outcome, 12% presented a mild neurological impairment and 8% were affected by severe cerebral palsy at the age of two years. The intact survival of a newborn infant of 450 g at birth is also reported.
