747 Caesarean sections carried out during the years 1974-97 inclusive have been examined on the basis of retrospective data. From the study it emerged that Caesarean section gradually increased in frequency from 6% in 1974 to 29% in 1986-87, that it is more frequently performed in primigravidas, that repeated Caesarean sections are increasing constantly and that its indications, whether maternal or foetal or mixed, are expanding. It also turned out that the practice of blood transfusion concomitant with C.S. has been failing continuously for 5 years. As for maternal and perinatal morbidity-mortality, it was evident that only neonatal morbidity is lower in C.S. compared to vaginal delivery, and only maternal mortality due to operated vaginal delivery is higher than C.S.-induced maternal mortality: for the rest, statistics all speak in favour of vaginal delivery. In spite of this, many Authors write in favour of the percentage increase in C.S. and the reasons are given.
对1974年至1997年（含）期间进行的747例剖宫产手术进行了回顾性数据分析。研究发现，剖宫产的频率从1974年的6%逐渐上升至1986 - 1987年的29%；初产妇中剖宫产更为常见；再次剖宫产的比例持续增加；剖宫产的指征，无论是母体因素、胎儿因素还是混合因素，都在不断扩大。还发现，剖宫产术中输血的情况已连续5年持续下降。至于孕产妇和围产期的发病率及死亡率，显然只有新生儿发病率在剖宫产时低于阴道分娩，且只有因阴道助产导致的孕产妇死亡率高于剖宫产所致的孕产妇死亡率：其他方面，统计数据均表明阴道分娩更具优势。尽管如此，许多作者仍支持剖宫产比例的增加，并给出了相应理由。
