Abstract

Purpose
: This study was undertaken to review the clinical and hematologic findings of the preterm infants delivered from pregnancy induced hypertension(PIH) mothers.
Methods
: The data were collected by reviewing the medical records on the current prognosis of preterm birth and sending questionnaires on the status of NICU. We reviewed the medical records from two university hospitals and two resident training hospitals in Gwangju-Chonnam to evaluate the neonatal prognosis of preterm birth from Jan. 1, 1995 to Dec. 31, 1997.
Results
: The average survival rate of total preterm babies was 79.6%. According to birth weights, survival rate from less than 1,000 gm was 10%, 1,000-1,499 gm was 55.3%, 1,500-1,999 gm was 82.2%. Maternal risk factors were pretmature rupture of membrane(42.2%), preterm labor (21.3%), PIH(10.7%), multiple pregnancy(8.2%) and incompetent internal os of cervix(4.2%). The average gestational age and birth weight were 34.2¡¾2.3 weeks and 1,940¡¾620 gm in the preterm infants born to mothers with PIH. The death rate was 12.9% in the preterm infants born to mothers with PIH. There were no significant differences in the incidence of RDS, use of assisted ventilation and surfactant, and frequency of the blood transfusion between the preterm infants born to normotensive mothers and those to mothers with PIH. There were significant differences in the total WBC count, platelet count and the concentration of the Mg, Ca and P between the preterm infants born to normotensive mothers and those to mothers with PIH.
Conclusion
: Our results may be helpful to predict the perinatal complications and manage the preterm infants by considering the clinical and hematologic findings of preterm infants born to mothers with PIH.
