Abstract

Clinical observation was performed on 1412 cases of neonates which was seen at S.N.U.H. during the past 2years from Jan. 1975 to Dec. 1976. The results ware as following: 1. The incidence of prematurity (below 38wks) was 12.1% and the incidence of S.B.W. was 9.8% 2. The mortality rate of prematurity and L.B.W. was 7.35%. 3. The average sex ration of male to female was: Total neonates: 1.14:1 Prematurity: 1.06:1 : 0.88:1 4. High incidence of prematurity and L.B.W. was peaked on Dec. and Feb. 5. The mortaity rate was: under 1000gm: 100% under 1500gm: 50% under 24wks:100% under 30wks: 63% So liability was increased after 30wks and 1500gm. 6. The aberage duration of admission date was: 1000~1500gm: 30days 1500~2000gm: 20days 2000~2500gm: 5~8days 7. The relating factors to prematurity and L.B.W. was C-section, preeclampsia and eclampsia, twin, breech delivery and congenital syhpilis. 8. Autopsy was done only one cases, and the diagnosis ws primary atelecasis. 9. High mortality was seen from Dec. to Feb. and nearly within 24 hours. 10. Low incidence was seen 20~24 maternal age group. 11. High incidence rate in primipars (49.5%). 12. The physiologic weight loss was seen about 4~% days, aerage 9% (167.0gm). 13. Weight gain was: under 1250gm: 14.2gm/d over 1250gm: 27.5gm/d 14. Average discharge weight was (over 5 days admission): 2150gm.
