【摘要】 目的 :探讨剖宫产率增高的因素及指征的变迁。方法 :对 8年来 4148例剖宫产病例进行回顾性研究分析。结果 :剖宫产率前 5年随年份增加而显著增高 (P <0 .0 5 ) ,后 3年增高不明显 (P >0 .0 5 ) ;剖宫产指征中胎儿因素增加不明显 (P >0 .0 5 ) ,但仍居首位 ,母亲因素及社会因素增加显著 (P <0 .0 5 ) ;围生儿死亡率下降 1.19倍。结论 :剖宫产率升高在一定程度上降低了围生儿死亡率。但围生儿死亡率的进一步降低需依靠整个围生医学的发展。更多还原

【Abstract】 Objective: To investigate the changing trend of cesarean section rates in 8 years. Methods: The total cases of cesarean section in 8 years(from 1991 to 1998)were analysed. Results: Cesarean section rates increased from 1991 to 1998. The causes of this trend may be related to the following:(1)Improvement of skill and safety of operation;(2)Change of indications of cesarean section;(3)Social factors. Conclusion: The decrease of perinatal mortality rate was not relevant only to the cesarean section rate, but dependent more on good perinatal care.更多还原
