조산아의 원인과 예후에 관한 연구 = Etiology and Outcome of Preterm Infants

국문 초록 (Abstract)

신생아 사망 및 유병율의 가장 중요한 요인인 조산아의 원인에 대해 연구분석하여 조산을 예방할 수 있는 가능한 비율 및 방법을 찾고자 하였으며, 재태연령 및 출생체중에 따른 조산아의 생존율을 조사하여 조산아의 처치에 기준을 두기 위하여 본 연구를 시행하였다.

We dertermined the causes and outcome of 288 cases of preterm infants at Sangye Paik Hospital from Jan. 1 to Dec. 31, 1991.
The results were as follows :
1.When the preterm births were divided by etiology, 48.6% followed spontaneous PROM, 31.9% followed spontaneous preterm labor, and 19.4% were indicated.
2.Of 288 preterm infants, 56.6% occured at 35-36 weeks, 30.9% at 31-34 weeks, and 12.5% at or before 30 weeks.
3.Of 13.9% of preterm births following spontaneous onset of labor before 35 weeks' gestation, 5.9% were at less than 3cm dilatation.
4.The neonatal mortality was 185.19 per 1000 live births in indicated delivery, 71.43 in PROM and 86.96 in spontaneous labor.
5.The survival rate was 25% at 26-27 weeks, 54% at 28-30 weeks and over 90% after 31 weeks.
6.When the survival rate was divided according: to birth weight, 28% in 900-1100gm, 60% in 1101-1500gm, 91% in 1501-2000gm, and 99.5% over 2000gm.
7.To increase the suvival rate of preterm infants, the minimal gestastional age should be 27 weeks' gestation and the birth weight be 900gm.
