摘　　要：目的探讨NST基线图形对诊断胎儿窘迫的临床价值。方法对2857例孕妇分娩前一周内最后一次NST基线类型、影响因素和妊娠结局进行回顾性研究。结果①异常妊娠组的0型、0～I小型和I小型发生率均明显高于正常妊娠组(P<0.005);两组的I型发生率差异无统计学意义(P>0.05)。②基线变异异常组的异常妊娠发生率明显高于NST无反应组(P<0.005);NST无反应组的胎儿窘迫发生率、新生儿窒息发生率均明显高于基线变异异常组(P<0.005);NST反应组的异常妊娠发生率、胎儿窘迫发生率、剖宫产率明显高于基线变异正常组(P<0.005,P<0.005,P<0.025)。③0型的胎儿窘迫发生率(45.59%)明显高于0～I小型、I小型和I型(P<0.05);0型的新生儿窒息发生率(23.53%)和Ⅱ°～Ⅲ°羊水粪染发生率(21.08%)最高。④0型的剖宫产率(89.71%)明显高于0～I小型(P<0.005);I小型(73.94%)的剖宫产率明显高于Ⅰ型(P<0.05)。结论胎心率基线变异减少或消失提示胎儿在宫内有不同程度的缺氧。Objective To study the clinical value of NST baseline graphics in diagnosis of fetal distress. Methods Totally 2,857 women underwent the last NST baseline graphics one week before their deliveries were enrolled in this study, their types of NST baseline graphics, the influencing factors and their pregnancy outcomes were retrospectively analyzed. Results The incidence rates of types of 0, 0- I small, and I small among abnormal pregnancy women were all significantly higher than those of normal ones （P〈 0. 005）. The rate of type I between abnormal and normal pregnancy women had no statistically significant difference （P 〉 0.05）. The incidence rate of abnormal pregnancy among abnormal baseline variability women was significantly higher than that of NST no response ones （P〈 0.00.5）. The incidence rates of fetal distress and newborn asphyxia among NST no response women were both significantly higher than those of abnormal baseline variability ones （P〈0.00.5）. The incidence rates of abnormal pregnancy, fetal distress, and cesarean section were all significantly higher than those of normal baseline variability ones （ P 〈 0.00.5, P 〈 0.00.5, P 〈 0. 025）. The incidence rate of fetal distress （4.5.59 % ） among type 0 women was significantly higher than those of types 0- I small, I small and I （P〈 0.05）. The incidence rates of newborn asphyxia （23.53%） and degree Ⅱ ^＋- Ⅲ ^＋ amniotic fluid meconium （21.08%） among type 0 women were the highest. The incidence rate of cesarean section among type 0 women （89.71% ） was significantly higher than that of type 0-I small ones （P〈 0. 005）. The incidence rate of cesarean section among type I small women.（73.94 % ） was significantly higher than that of type I ones （P〈 0.05）. Conclusions Reduced or disappeared fetal heart baseline variability hints the different degrees of fetal anoxia.
