399명의 고위험 임부를 대상으로 483예의 NST를 실시한 본 연구에서는 다음과 같은 결과를 얻을 수 있었다. 1. 대상임부의 적응증에서 고혈압성 질환이 107예(23.1%)로 가장 많았고, 과숙아 95예, 조산 31예등의 순이었다. 2. 평균 임신주수는 40.04주였고, 평균 신생아체중은 3,050 gm이었다. 3. NST 483예중 반응성은 411예(85.1%)였으며, 무반응성은 69예(14.3%)였고, 판독부적합은 3예(0.6%)였다. 4. NST 반응성 307예중 저 Apgar 점수를 나타낸 경우가 4예(1.3%)였던 반면에, 무반응성 56예중 13예(23.2%)에서 나타나 통계학적으로 유의한 차이를 보였다.

For the antepartal evaluation of fetal well-being in high risk pregnancy, the nonstress test has been found to be clinically efficacious. From June 1, 1981, to April 20, 1982, 483 nonstress tests were performed on 399 women with high risk pregnancy. The results of this study were as follows; 1. The most common indication for nonstress test was hypertensive disorders during pregnancy(23.1%). 2. The mean gestation week in nonstress test group was 40.04 week, and the mean birth weight in delivered cases was 3,050 gm. 3. Among 483 nonstress tests, reactive result was noted in 411 cases(85.1%), nonreactive in 69 cases(14.3%), and unsatisfactory in 3 cases(0.6%). 4. Low Apgar score was found in 23.2% (13/56 cases) in nonreactive group, and 1.3% (4/307) cases) in reactive group respectively
