摘要
目的从初产妇剖宫产率和适应证的变化中,探讨剖宫产率升高的原因。方法抽样选择1984～2004年21年初产妇剖宫产病例671例,比较及分析其剖宫产率及适应证的变化。结果①剖宫产率呈逐年上升趋势,而产钳率呈逐年下降趋势;②剖宫产占难产分娩的比例逐年增高,同期产钳助产占难产分娩的比例逐年下降;③2000年以前居于前4位的剖宫产手术指征是:相对头盆不称、胎儿窘迫、胎位异常、胎膜早破;1999年起珍贵儿指征已出现,2004年已跃居第2位;④新生儿出生体重的增加和产妇年龄的增大也是影响初产妇剖宫产率增高的原因。结论初产妇增多并不是引起剖宫产率增高的主要原因。应加强孕产期保健,鼓励产妇阴道分娩,严格掌握剖宫产指征。
Objective To investigate the changing trend of Cesarean section rates and indications of primipara, and to analyze the causes of increased cesarean section rates. Methods A total of 671 primiparae who underwent Cesarean section were selected sampling from 1984 to 2004, and changes in Cesarean section rates and indications were analyzed. Results（1） The Cesarean section rate increased gradually year after year since 1984, while decrease trend of forceps delivery rate was observed. （2） The ratio of cesarean section birth to dystocia delivery increased year by year, with reverse trend of forceps delivery. （3） The top four indications of Cesarean section before 2000 were relative cephalopelvic disproportion, fetal distress, breech presentation and premature rupture of membranes. Precious fetus became one of the indications since 1999 and up to be the second in 2004. （~ The growing birth weight of newborn and advancing maternal age were also the influencing factors to elevate cesarean section rate. Conclusions The increase of primipara is not the main cause of increase of cesarean section rate. We should strengthen maternal health care, encourage spontaneous vaginal delivery and control the indications of cesarean section.
