Operative delivery prevalence is considered in two periods: 1980-1985 and 1986-1990. Reduced prevalence of repeated cesarean section is reported for the second period as opposed to the first one. A larger prevalence of cesarean sections for anomalous presentation (breech presentation included), fetal distress. EPH gestosis, abruptio placentae is reported in the second half of '80's. Vacuum Extractor applications are reduced in the second period compared to the first one for with concern secondary uterine hypokinesia; larger V.E. applications are reported in the second period for fetal distress in the second stage of labor. Relatively rare forceps applications in both periods.
1980 - 1985年和1986 - 1990年。与第一个时间段相比，第二个时间段重复剖宫产的发生率有所降低。80年代后半期，因胎位异常（包括臀位）、胎儿窘迫、妊娠高血压综合征、胎盘早剥进行剖宫产的发生率更高。与第一个时间段相比，第二个时间段因担心继发性子宫收缩乏力，真空吸引器的使用减少；第二个时间段因第二产程胎儿窘迫，真空吸引器的使用更多。两个时间段产钳使用都相对较少。
