The authors suggest that the coefficient, representing the ratio between the sizes of the small pelvis section and fetal head section, be used for the prediction of labor outcome for the fetus in women with a contracted pelvis. When the coefficient values K1-K4 were lower than 1.32, 1.35, 0.68, and 0.79, more than 90% of the newborns developed signs of cerebral circulation disorders, this prompting the use of cesarean section for this group of pregnant women. Timely correction of the policy of labor management with due consideration for the anatomical features of the pelvis helped reduce the perinatal mortality in multigravidae to 5/1000, mainly at the expense of carrying out planned cesarean section and monitoring in labor.
作者建议,用代表小骨盆段与胎头段大小之比的系数来预测骨盆狭窄女性胎儿的分娩结局。当系数值K1 - K4低于1.32、1.35、0.68和0.79时,超过90%的新生儿出现脑循环障碍迹象,这促使对这组孕妇采用剖宫产。充分考虑骨盆解剖特征及时纠正分娩管理策略,有助于将经产妇围产儿死亡率降至5‰,这主要得益于实施计划性剖宫产和产时监测。
