用灰色系统理论分析剖宫产率上升的原因

The Reasons of Cesarean Section Rate Increasing Analyzed by Grey Model Theory

目的 :为降低剖宫产率提供依据。方法 :采用灰色系统理论关联度分析法 ,对影响剖宫产率的十种因素进行分析。结果 :因胎儿宫内窘迫剖宫产数排在首位 (关联度为0 .82 0 ) ;其他因素依次是头盆不称 (0 .71 0 )、胎儿珍贵 (0 .6 2 6 )、臀位或横位 (0 .6 2 4 )、妊高症(0 .6 1 9)、胎膜早破 (0 .6 0 9)、脐带绕颈 (0 .6 0 9)、二次剖宫产及前置胎盘 (0 .6 0 7)、宫缩乏力 (0 .6 0 4 )、高龄初产 (0 .6 0 1 )。结论 :提高胎儿宫内窘迫的诊断水平、减少巨大儿的出生、控制社会因素。

Objective: To provide foundation for decreasing cesarean section rate. Methods: Contacting relation degree of Grey Model Theory was used in analyzing ten reasons of effecting cesarean section rate. Results: The highest cesarean section rate is the fetal distress in uterus (0.820), the next is cephalopelvic disproportion (0.710), fetus valuable (0.626), breech and transverse lie (0.624), hypertension of pregnancy syndrome (0.619), premature rupture of fetal membranes (0.609), umbilical cord around neck (0.609), secondcesareansectionandplacentaprevia(0.607),uterineatony(0.604), firstchildbirthatelder age (0.601). Conclusion: The key of decreasing cesarean section rate is to improve the diagnosis level of fetal distress in uterus, decrease birth of macrosomia, control social factors and find abnormal fetal position in time.
