Preterm delivery of infants before 37 completed weeks gestation complicates 8-10% of births and is considered as a leading cause of neonatal morbidity and mortality(Berkowitz and Papiernik, 1993). Moreover, the sequelae for those infants who survive often causes permanent disabilities with mental and physical impairment. Efforts to prevent preterm deliveries have been hampered by a poor understanding of the underlying pathophysiology, inadequate diagnostic tools, and generally ineffective therapies. However not all preterm deliveries are the consequence of preterm parturition.
The major problems of preterm deliveries are preterm, premature rupture of fetal membranes, spontaneous preterm labor in pregnancies with intact fetal membranes, and complications of pregnancies that jeopardize fetal or maternal health(or both) that mandate delivery for reasons independent of labor or rupture of the membranes. The authors reviewed the medical records of 199 patients who had delivered preterm babies, of 210 babies of theirs including 11 sets of twins and of the same number of those who had given birth at term at the department of Obstetrics and Gynecology,
Konkuk University Medical Center from January 1, 1995 to December 31, 1997 and tried to find out the risk factors that could cause preterm deliveries.
The results were as follows : 1. The overall incidence of preterm delivery was 8.4%; 199 cases among 2,372 cases of total deliveries.
2. The mean age of the mothers of preterm babies(28.9±0.35 year) was statistically significantly higher than that of the mothers of term babies(27.8%±0.25 year), (p<0.05).
3. The mean gravidity of mothers of preterm babies(2.92±0.14) was statistically significantly higher than that of the mothers of term babies(2.39±0.09), (p<0.05).
4. The mean parity of mothers of preterm babies(1.80±0.06) was statistically significantly higher than that of the mothers of term babies(1.62±0.04), (p<0.05).
5. The mean number of artificial abortion of the mothers of preterm babies(1.14±0.13) was significantly higher than that of the mothers of term babies(0.73±0.07), (p<0.05).
6. There was no significant difference between the mean hemoglobin concentration of the mothers of preterm and term delivery group.
7. The mean Apgar score of the babies of preterm and term babies were 6.96±0.19 and 8.73±0.05 at 1 minute; 8.56±0.14 and 9.78±0.04 at 5 minute. There were statistical significances among each of those values (p<0.05).
8. The perinatal morbidity and mortality rate of prematurely born babies were 60.5% and 27.1%.
9. The major obstetrical complications of preterm deliveries were preterm labor(44.2%), PROM(44.2%), followed by PIH(14.1%) and multiple pregnancy(11.1%).
10. The major postnatal complications of the premature babies were sepsis(15.8%), germinal matrix hemorrhage(15.2%), perinatal asphyxia(8.5%), hyaline membrane disease(5.5%) and patent ductus arteriosus(4.8%) in order.
