A statistical observation was performed on 13,317 cases of neonates who had been delivered at Taegu Catholic Hospital during the past 3 years from Jan, 1st 1988 to Dec. 31st 1990.
@ES The results obtained were as follows:
@EN 1) Among 13,317 neonates, the male was 7,234 and the female 6,083, with the sex ratio of male to female being 1.19:1
2) Percentage distribution by birth weight was 5.6% for 2.500gm or less, 3.3% for 4,001gm or more. The mortality rate was 8.4 per 1,000 live births and 61.1% for very low birth weight infants. 57.1% of neonatal death occured within 24 hours
after
birth
and the most common cause of death was prematurity (53.6%).
3) The mean growth data at birth were as following: Weight: 3,253±484gm in male, 3,160±456gm in female; Height: 50.11±2.59cm in male, 49.57±2.50cm in female; Head circumference: 33.60±1.74cm in male, 33.12±1.64cm in female; Chest
circumference:
32.83±1.83cm in male, 32.41±1.75cm in female.
4) Among 13,317 noenates, 352 (2.6%) were under 37 wks and 555 (4.2%) above 42 wks and 92.6% very low birth weight infants under 37 wks.
5) 44.2% of 13,317 neonates, was the highest-density distribution which was between 47.5∼52.4cm by length and 3,001∼3,500gm by weighing.
6) The admission rate was 13.7% and the causes of admission in order of frequency were neonatal infection (47.9%), premature or low birth weight infant (12.9%), neonatal jaundice (11.3%), asphyxia neonatorum (6.9%), respiratory disress syndrome
(5.4%),
etc.
7) Among all neonates, 2.2% had neonatal asphyxia (a 1-minute Apgar score of 6 or less). The highest incidence was 19.7% in the breech delivery group by delivery mode and 33.6% in the prematurity by gestational age.
8) The types of delivery in order of frequency were spontaneous vaginal delivery (72.5%), Cesarean section (21.9%), vacuum delivery (5.0%), breech delivery (0.5%) and forceps delivery (0.1%).
9) The incidence of twin babies was 182 (91 pairs), 1.37% of all neonates, 1 pair per 145 neonates. Of all twins, 50.5% were below 2,500gm of birth weight and 20.9% premature.
10) The incidence of neonatal jaundice was 63.0%. Of icteric neonates, 8.2% had pathologic jaundice treated by phototherapy or exchange transfusion.
11) Among all neonates, there were 7,705 cases (57.9%) with high risk factors; the order of frequency was Cesarean section (37.8), meconium stained (13.3%), premature rupture of membranes over 24 hours (12.7%), birth weight 2,500gm or less
(9.6%),
etc.
