There is considerable variation in the timing of elective pre-labour caesarean section at term where there is no immediate threat to the life of the mother or baby. Given the outcomes, elective or pre-labour caesarean section ought not be offered or performed before 39 completed weeks' gestation. Primary data sources indicated that the rate of term elective caesarean sections with no medical indication undertaken before 39 weeks' gestation at our institution was ~30% in 2005 and 2006. A project was undertaken during the 6-month period from March 2007 to August 2007 with the aim of reducing this rate to 10%. Over the 6-month period, the rate of elective caesarean section with no medical indication done before 39 weeks' gestation in the target group fell to 10%. Over the same timeframe the number of admissions to the neonatal nursery of term babies born by caesarean section at less than 39 weeks fell to zero. Although the numbers are small and not statistically significant, this work suggests implementation across larger jurisdictions or states could result in significant improvements in clinical outcomes.
在对母亲或婴儿生命无直接威胁的情况下,足月选择性剖宫产的时机存在很大差异。鉴于相关结局,不应在妊娠满39周之前进行选择性或临产前剖宫产。主要数据来源表明,2005年和2006年在我们机构,妊娠39周前无医学指征的足月选择性剖宫产率约为30%。在2007年3月至2007年8月的6个月期间开展了一个项目,目标是将该比率降至10%。在这6个月期间,目标组中妊娠39周前无医学指征的选择性剖宫产率降至10%。在同一时间段内,孕周小于39周的剖宫产足月儿入住新生儿重症监护室的人数降至零。尽管数量较少且无统计学意义,但这项工作表明,在更大的司法管辖区或州推广实施可能会显著改善临床结局。
