目的：探讨分娩方式的变化对产科质量的影响。方法：收集我院１９９３ 年至１９９７ 年不同分娩方式的资料，计算出剖宫产手术平均每年递增速度和阴道助产平均每年递减速度，同时计算出５ 年中每年产后出血率、新生儿死亡率和新生儿窒息率。结果：统计分析表明我院５ 年中剖宫产率以平均每年１２％ 的速度递增，而阴道助产率以平均每年１３．８４％ 的水平下降。分娩方式变化后，新生儿窒息的发生率１９９７ 年比１９９３ 年明显下降（Ｐ＜ ０．０５），而产后出血率、新生儿死亡率下降不明显（Ｐ＞ ０．０５）。结论：剖宫产率上升，阴道助产率下降，可降低新生儿窒息率，但是不能有效降低母亲产后出血率及新生儿死亡率。
Objective: To explore the impact of changes in mode of delivery on the quality of obstetrics. Methods: The data of different modes of delivery in our hospital from 1993 to 1997 were collected to calculate the average yearly rate of cesarean section operation and the average annual rate of vaginal delivery. At the same time, the annual postpartum hemorrhage rate, neonatal mortality rate And neonatal asphyxia rate. Results: Statistical analysis showed that in our hospital, the rate of cesarean section increased at an average rate of 12% per year in 5 years, while the vaginal delivery rate decreased at an average rate of 13.84% per year. Changes in mode of delivery, the incidence of neonatal asphyxia in 1997 decreased significantly compared with 1993 (P <0.05), while postpartum hemorrhage, neonatal mortality did not decline significantly (P> 0.05). Conclusion: Cesarean section rate increases and vaginal delivery rate decreases, which can reduce neonatal asphyxia rate, but can not effectively reduce maternal postpartum hemorrhage rate and neonatal mortality rate.
