A statistical obsevation was performed on 13,317 cases of neonates who had been delivered at Taegu Catholic Hospital during the past 3 years from Jan. 1 st 1988 to Dec. 31 st 1990.
The results obtained were as follows:
1) Among 13,317 neonates, the male was 7,234 and the femlae 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 4,001 gm 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¡¾484gm in male, 3,160¡¾456gm in female;
Height: 50.11¡¾2.59cm in male, 49.57¡¾2,50cm in female;
Head circumference: 33.60¡¾1.74cm in male, 33.12¡¾1.64cm in female;
Chest circumference : 32.83¡¾1.83cm in male, 32.41¡¾1.75cm 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(21.9%), 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. |
